I don't have gradle.build, why? - android-studio

I am using Android-Studio to build my app. In order to add libraries, I need to edit build.gradle file but I don't see it anywhere. Even if I changed files-view from android to project and vice-versa .
Why don't I see/have build.gradle ?

Check in your git repository if it contains the build.gradle files.
If not, you can just add manually to your project.
You should have something like this:
root
|--app
|----build.gradle
|--build.gradle
|--settings.gradle
You can also create a new blank project and copy the build.gradle files into your existing project (of course in the app/build.gradle file you have to change the values and the dependencies).

With huge help from #JuLes (commentting on my question) I figure out how to solve it. Here is what I did:
I totally removed Android-Studio following this guidance, then ...
I installed Gradle from this link, then ...
I re-installed Android-Studio following this link:
I am gussing the main problem was that I didn't installed Gradle manually and hence Android-Studio was using some sort of Gradle-Wrapper to allow the application to run.
Now, finally I can edit build.gradle.

Android Studio: build.gradle (project) not visible in "Project"

I am trying to rebuild an old (working) project in AndroidStudio. It builds Ok but strangely, the project's build.gradle is not visible in the AS Project tab.
Note that the module's build.gradle appears but not the project's build.gradle.
Both files ARE indeed there
Directory of C:\dev\AndroidProjects\apps\Passwords\app
11/09/2020 04:16 PM 767 build.gradle
1 File(s) 767 bytes
Directory of C:\dev\AndroidProjects\apps\Passwords
11/09/2020 03:13 PM 352 build.gradle
1 File(s) 352 bytes
The project otherwise builds just fine.
The projects build.gradle IS active: If I make changes to it outside AS using a text editor, the changes DO take effect.
What I've Tried:
Restart PC and AS
Cleaned/Rebuilt Project
Invalidate Caches & Restart
Searched SO for problem. Question 47406517 was similar but solution didn't work
Copy build.gradle from another known-good project.
Notes:
Android Studio: V3.6.3
PC: Win10-64
Project Name: "Passwords"
I'm at a loss for other things to try. Any suggestions?
(I guess as a work-around, I can always use an external text editor but that's annoying).
I found the answer in SO question #46230078. The solution was simple: Close AndroidStudio, delete the directory ".idea" from the project directory, restart AndroidStudio. This did it!

Cannot open a library at 'FileMapping' in Android studio

Cannot open a library at 'FileMapping(from=/home/alamin/Database/Automail/app/libs/additional.jar, to=/home/alamin/.gradle/caches/transforms-2/files-2.1/5c80954b8617a057a166d4547256bdee/jetified-additional.jar)'
I have added 'additional.jar' in libs folder and have added this dependency in build.gradle
implementation files('libs/additional.jar')
I have also try this solution form this question:
Cannot open a library at 'FileMapping'
You've just deleted the jetified-additional.jar file from the lib folder directly. Now you've to remove the jetified-additional.jar file from the dependencies of the program too. So go on File - Project structure - Dependencies - under app find the "jetified-additional.jar" and remove it from here. Now again run the project the error will not be there because you've also removed the jetified-additional.jar from the file tree structure of your project.
Hope this will help!!! Happy coding :)
I also answered this here Cannot open a library at 'FileMapping'

Android Studio cannot open Android project with Kotlin DSL

I have converted one of our Android projects from the old Groovy settings.gradle and build.gradle files to the new Kotlin DSL, i. e. settings.gradle.kts and build.gradle.kts.
While "it works on my machine" - in particular: the original project I converted from Groovy to Kotlin works fine in its original directory - all my co-workers are unable to open the project when they clone the repo. Importantly, neither can I open the project myself (with the same AS installation on the same machine) when I clone the repo to some other directory. So, I suspect there is some additional detail missing in some configuration file but I cannot seem to figure out which...
Details:
When I just use File > Open... and then select the project folder, I only get the error message "The project 'xxx' is not a Gradle-based project"
When I instead go through Import Project (Gradle, Eclipse ADT, etc.) and then select Import project from external model and Android Gradle Android Studio will create an empty build.gradle file and fail with the error message "ERROR: Plugin with id 'com.android.library' not found." Deleting the build.gradle just goes back to the error message I described in the first bullet point.
I am aware of this Github issue, which seems to describe the same problem, but it's been very quiet and I thought someone around here must have figured out a solution to this...
Oh, command line builds work everywhere - this is purely an Android Studio problem.
UPDATE: When I copy the whole project to a new folder (instead of cloning the repository) I can open it without any problems. So, am I correct in assuming that there must be something inside the folder - but not in Git - that makes it work?
I was able to 'fix' it by deleting the .idea directory and reopening the project. The .idea directory is usually not committed in git but I guess copying the directory invalidates the directory structures in the files within the .idea directory.
The whole bug is easily reproducible when you click on File > Re-import Gradle project.
#Boni2k answer does not work for me.
I have to rename the root build.gradle.kts back to build.gradle, fix the syntax error, sync the project (which works fine immediately), and rename the file back to build.gradle.kts. Then the error is gone and I can sync the project successfully.
What I did to raise the error was that I moved the project to a different folder, and rename the project.

How to create a library project in Android Studio and an application project that uses the library project

How do I create an Android Library Project (e.g. com.myapp.lib1) and the application project (e.g. com.myapp.app) and make the build system include com.myapp.lib1 on the application project?
I went to the Project Structure -> Modules -> My App project and added a dependency to the lib project. IntelliJ now can recognize classes from the lib project when used in the app project, but when I run the app project, there are errors like:
Gradle: error: package com.myapp.lib1 does not exist
I wonder why there is no example of stand alone jar project.
In eclipse, we just check "Is Library" box in project setting dialog.
In Android studio, I followed this steps and got a jar file.
Create a project.
open file in the left project menu.(app/build.gradle): Gradle Scripts > build.gradle(Module: XXX)
change one line: apply plugin: 'com.android.application' -> 'apply plugin: com.android.library'
remove applicationId in the file: applicationId "com.mycompany.testproject"
build project: Build > Rebuild Project
then you can get aar file: app > build > outputs > aar folder
change aar file extension name into zip
unzip, and you can see classes.jar in the folder.
rename and use it!
Anyway, I don't know why google makes jar creation so troublesome in android studio.
To create a library:
File > New Module
select Android Library
To use the library add it as a dependancy:
File > Project Structure > Modules > Dependencies
Then add the module (android library) as a module dependency.
Run your project. It will work.
Google’s Gradle Plugin recommended way for configuring your gradle files to build multiple projects has some shortcomings If you have multiple projects depending upon one library project, this post briefly explain Google’s recommended configuration, its shortcomings, and recommend a different way to configure your gradle files to support multi-project setups in Android Studio:
An alternative multiproject setup for android studio
A Different Way :
It turns out there’s a better way to manage multiple projects in Android Studio. The trick is to create separate Android Studio projects for your libraries and to tell gradle that the module for the library that your app depends on is located in the library’s project directory. If you wanted to use this method with the project structure I’ve described above, you would do the following:
Create an Android Studio project for the StickyListHeaders library
Create an Android Studio project for App2
Create an Android Studio project for App1
Configure App1 and App2 to build the modules in the StickyListHeaders project.
The 4th step is the hard part, so that’s the only step that I’ll describe in detail. You can reference modules that are external to your project’s directory by adding a project statement in your settings.gradle file and by setting the projectDir property on the ProjectDescriptor object that’s returned by that project statement:
The code one has to put in settings.gradle:
include ':library1'
project(':library1').projectDir = new File('../StickyListHeader/library1')
If you’ve done this correctly, you’ll notice that the modules referenced by your project will show up in the project navigator, even if those modules are external to the project directory:
This allows you to work on library code and app code simultaneously. Version control integration also works just fine when you reference modules externally this way. You can commit and push your modifications to the library code just like you can commit and push modifications to your app code.
This way of setting up multiple projects avoids the difficulties that plague Google’s recommended configuration. Because we are referencing a module that is outside of the project directory we don’t have to make extra copies of the library module for every app that depends on it and we can version our libraries without any sort of git submodule nonsense.
Unfortunately, this other way of setting up multiple projects is very difficult to find. Obviously, its not something you’ll figure out from looking at Google’s guide, and at this point, there’s no way to configure your projects in this way by using the UI of Android Studio.
Check out this link about multi project setups.
Some things to point out, make sure you have your settings.gradle updated to reference both the app and library modules.
settings.gradle: include ':app', ':libraries:lib1', ':libraries:lib2'
Also make sure that the app's build.gradle has the followng:
dependencies {
compile project(':libraries:lib1')
}
You should have the following structure:
MyProject/
| settings.gradle
+ app/
| build.gradle
+ libraries/
+ lib1/
| build.gradle
+ lib2/
| build.gradle
The app's build.gradle should use the com.android.application plugin while any libraries' build.gradle should use the com.android.library plugin.
The Android Studio IDE should update if you're able to build from the command line with this setup.
For Intellij IDEA (and Android Studio) each library is a Module. Think of a Module in Android Studio as an equivalent to project in Eclipse. Project in Android Studio is a collection of modules. Modules can be runnable applications or library modules.
So, in order to add a new android library project to you need to create a module of type "Android library". Then add this library module to the dependency list of your main module (Application module).
The simplest way for me to create and reuse a library project:
On an opened project file > new > new module (and answer the UI questions)
check/or add if in the file settings.gradle: include ':myLibrary'
check/or add if in the file build.gradle:
dependencies {
...
compile project(':myLibrary')
}
To reuse this library module in another project, copy it's folder in the project instead of step 1 and do the steps 2 and 3.
You can also create a new studio application project
You can easily change an existing application module to a library module by changing the plugin assignment in the build.gradle file to com.android.library.
apply plugin: 'com.android.application'
android {...}
to
apply plugin: 'com.android.library'
android {...}
more here
You can add a new module to any application as Blundell says on his answer and then reference it from any other application.
If you want to move the module to any place on your computer just move the module folder (modules are completely independent), then you will have to reference the module.
To reference this module you should:
On build.gradle file of your app add:
dependencies {
...
compile project(':myandroidlib')
}
On settings.gradle file add the following:
include ':app', ':myandroidlib'
project(':myandroidlib').projectDir = new File(PATH_TO_YOUR_MODULE)
Don't forget to use apply plugin: 'com.android.library' in your build.gradle instead of apply plugin: 'com.android.application'
Documentation Way
This is the recommended way as per the advice given in the Android Studio documentation.
Create a library module
Create a new project to make your library in. Click File > New > New Module > Android Library > Next > (choose name) > Finish. Then add whatever classes and resourced you want to your library.
When you build the module an AAR file will be created. You can find it in project-name/module-name/build/outputs/aar/.
Add your library as a dependency
You can add your library as a dependency to another project like this:
Import your library AAR file with File > New Module > Import .JAR/.AAR Package > Next > (choose file location) > Finish. (Don't import the code, otherwise it will be editable in too many places.)
In the settings.gradle file, make sure your library name is there.
include ':app', ':my-library-module'
In the app's build.gradle file, add the compile line to the dependencies section:
dependencies {
compile project(":my-library-module")
}
You will be prompted to sync your project with gradle. Do it.
That's it. You should be able to use your library now.
Notes
If you want to make your library easily available to a larger audience, consider using JitPac or JCenter.
Had the same question and solved it the following way:
Start situation:
FrigoShare (root)
|-Modules: frigoshare, frigoShare-backend
Target: want to add a module named dataformats
Add a new module (e.g.: Java Library)
Make sure your settings.gradle look like this (normally automatically):
include ':frigoshare', ':frigoShare-backend', ':dataformats'
Make sure (manually) that the build.gradle files of the modules that need to use your library have the following dependency:
dependencies {
...
compile project(':dataformats')
}
Purpose: Android library at single place - Share across multiple projects

As theczechsensation comment above I try to search about Gradle Build Varians and I found this link: http://code.tutsplus.com/tutorials/using-gradle-build-variants--cms-25005
This is a very simple solution. This is what I did:
- In build.gradle:
flavorDimensions "version"
productFlavors {
trial{
applicationId "org.de_studio.recentappswitcher.trial"
flavorDimension "version"
}
pro{
applicationId "org.de_studio.recentappswitcher.pro"
flavorDimension "version"
}
}
Then I have 2 more version of my app: pro and trial with 2 diffrent packageName which is 2 applicationId in above code so I can upload both to Google Play. I still just code in the "main" section and use the getpackageName to switch between to version. Just go to the link I gave for detail.
There are two simplest ways if one does not work please try the other one.
Add dependency of the library inside dependency inside build.gradle file of the library u r using, and paste ur library in External Libraries.
OR
Just Go to your libs folder inside app folder and paste all your .jar e.g Library files there Now the trick here is that now go inside settings.gradle file now add this line "include ':app:libs'" after "include ':app'" It will definitely work...........:)
In my case, using MAC OS X 10.11 and Android 2.0, and by doing exactly what Aqib Mumtaz has explained.
But, each time, I had this message : "A problem occurred configuring project ':app'. > Cannot evaluate module xxx : Configuration with name 'default' not found."
I found that the reason of this message is that Android 2.0 doesn't allow to create a library directly. So, I have decided first to create an app projet and then to modify the build.gradle in order to transform it as a library.
This solution doesn't work, because a Library project is very different than an app project.
So, I have resolved my problem like this :
First create an standard app (if needed) ;
Then choose 'File/Create Module'
Go to the finder and move the folder of the module freshly created in your framework directory
Then continue with the solution proposed by Aqib Mumtaz.
As a result, your library source will be shared without needing to duplicate source files each time (it was an heresy for me!)
Hoping that this help you.

How To Add Parse to an Android Studio Project?

I'm trying to use the Parse library in Android Studio. I have used the basic example on their website and added the jar to the libs folder as well as added as a global library. Nothing seems to be working without errors:
Gradle: package com.parse does not exist
Gradle: package com.parse does not exist
Gradle: package com.parse does not exist
Gradle: cannot find symbol variable Parse
Gradle: cannot find symbol variable ParseAnalytics
Gradle: cannot find symbol class ParseObject
Gradle: cannot find symbol class ParseObject
Android Studio gives no errors in the code.
I encountered the same problem too and here's what I did:
I placed the entire Parse-1.2.5 in the libs folder (I didn't have to create the folder as Parse's quickstart said).
Open the build.grade file. There are two of them - open the one that's at the same level as the src folder
You'll see two instances of "dependencies". Add the following to the "dependencies" that is NOT nested under "buildscript":
compile files('libs/Parse-1.2.5/Parse-1.2.5.jar')
If that still doesn't work, try right clicking the Parse-1.2.5.jar file and select "Add to Project Library"
Hope that helps!
As of version 1.10.0 the Parse SDK is open source and available on Maven, so now you can just put this in gradle:
compile 'com.parse:parse-android:1.10.0'
Just replace 1.10.0 with whatever the newest verison is at the time you read this.
Alternatively, if you like living on the edge, you can tell gradle to auto-update:
compile 'com.parse:parse-android:1.+'
EDIT: On 1/28/16 Facebook announced that they are retiring the Parse service, so if you are starting a new project I would urge you to consider using a different service.
The problem is that gradle doesnt do a proper rebuild and somehow still reads a cached version of the old build script. Add the libs as per above reply then open a terminal and do a gradle clean. If you are running on windows (or any platform for that matter) I suggest you do a quick internet search on "intellij clean" to see what it does and then simply do a manual clean by deleting the appropriate folder. This should do the trick!
edit: before manually deleting the appropriate folders/caches you can also first try clicking on file -> invalidate caches. If this still doesnt work manually delete all the appropriate folders and caches
1) I unzip the folder into the libs folder:
YourProject/app/libs/Parse-1.9.2/ <<< here all the jar files.
2) and then in the dependencies section from your build.gradle, I set:
dependencies {
...
// Parse 1.9.2
compile 'com.parse.bolts:bolts-android:1.+'
compile fileTree(dir: 'libs/Parse-1.9.2', include: 'Parse-*.jar')
...
}
I set the specific folder where the jars are contained dir: 'libs/Parse-1.9.2'
Hope it helps!
In your app gradle add below code
dependencies {
compile 'com.parse.bolts:bolts-android:1.+'
compile 'com.parse:parse-android:1.+'
}
In AndroidManifest.xml file add below permission
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
In your Application class inside onCreate() method add below code
Parse.initialize(this, "application_id", "client_key");
ParseInstallation.getCurrentInstallation().saveInBackground();
then run. Hope this works, for more info https://parse.com/apps/quickstart#parse_data/mobile/android/native/existing
Place the contents of the Parse-1.. folder in to your libs directory ... not the Parse-1.. folder itself. That worked for me.
donwload parse SDK for android and follow instruction given on below mentioned link:
https://parse.com/apps/quickstart#parse_data/mobile/android/native/existing
Add the SDK to your app in Android Studio
Add the following to your build.gradle
dependencies {
compile 'com.parse.bolts:bolts-android:1.+'
compile 'com.parse:parse-android:1.+'
}
and then
Add the following to your Application#onCreate():
Parse.initialize(new Parse.Configuration.Builder(myContext)
.applicationId("YOUR_APP_ID")
.server("http://YOUR_PARSE_SERVER:1337/parse")
...
.build()
);
Your app must request the INTERNET and ACCESS_NETWORK_STATE permissions, if it isn't doing so already. Add the following lines inside the tag in your AndroidManifest.xml:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
Compile and run!
After installing the SDK, copy and paste this code into your app, for example in your Activity#onCreate():
ParseObject testObject = new ParseObject("TestObject");
testObject.put("foo", "bar");
testObject.saveInBackground();
You will also have to add an import statement at the top of your file:
import com.parse.ParseObject;
Run your app. A new object of class TestObject will be sent to the Parse Server and saved.
Unzip the Parse.zip file
Go to Android Studio. Change Android to Project (top left corner).
Expand the folders and find "libs".
Copy the "parse" folder and paste it in the "libs".
Now, under the "src" open build.gradle
Paste the following under dependencies-
compile files('libs/Parse-1.9.4/Parse-1.9.4.jar')
compile files('libs/Parse-1.9.4/bolts-android-1.2.0.jar')
(give your Parse version name)
Done. You gotta ready to go!!
