I am using Android Studio with Gradle. Where in my project do I find the jar files that I am pulling with Gradle with say
compile 'com.squareup.picasso:picasso:2.5.2'
Digging through Android Studio I find a xml file under
/Users/myname/StudioProjects/Myproject/.idea/libraries/picasso_2_5_2.xml
I look inside, opened a terminal and routed to the path suggested. I get to the jar. Now I want to browse it. If I source for picasso-2.5.2-sources.jar using Spotlight Search then nothing is found. So obviously I cannot just get to it to view what's inside. So how might I do that?
When running Gradle, a .gradle folder is created in your home directory: ~/.gradle/caches.

is there a way anyone can help me… or may be tell me where to save gradle-6.1.1.pom on my device.
Thank you
build.gradle file must be like that
dependencies {
classpath 'com.android.tools.build:gradle:7.2.0'
gradle-wrapper.properties file must be like that
distributionUrl=https://services.gradle.org/distributions/gradle-7.4.2-all.zip
I am developing an app using android studio and java. I downloaded gradle 6.1.1.zip and it was working fine. I formatted my system and installed android studio. I want to use the same gradle but I'm getting error.
file:/C:/sam/gradle-6.1.1-all.zip' contains too many directories. Expected to
find exactly 1 directory.
The zip file contains only one gradle. How do I solve this issue?
According to this android dev doc, you can specify the gradle version either in: File > Project Structure > Project menu in Android Studio, or in the file gradle/wrapper/gradle-wrapper.properties . In your case, for gradle 6.1.1.zip, you use the following in the above mentioned file:
...
distributionUrl = https\://services.gradle.org/distributions/gradle-6.1.1-all.zip
...
Android Studio displays in all java files in red : “cannot resolve symbol R” but the project compiles and runs.
I have tried every solution here:
Android Studio "cannot resolve symbol" but project compiles and works, but with no luck.
I tried to :
invalidate caches and restart android studio
delete .gradle and .idea folders
clean and rebuild the project
install a new version of android studio
mess up with gradle file then undo changes and sync project
One thing that I want to try, but I don't know how to achieve, is to reopen the project from scratch as I was opening it for the first time, but I don't know how to do this.
I also tried answers from here:
Android Studio says "cannot resolve symbol" but project compiles,
but again with no luck.
Android studio version = 3.2.1
dependency versions in gradle project file:
classpath 'com.android.tools.build:gradle:3.4.0-alpha01'
classpath 'com.google.gms:google-services:4.0.0'
For some reason that i do not understand ,
this combination of build versions made the issue :
grade version = 4.10.1
classpath 'com.android.tools.build:gradle:3.4.0-alpha01'
when i switched to these build versions :
grade version = 4.6
classpath 'com.android.tools.build:gradle:3.2.1'
The issue was solved !
File -> Close project
Open an existing Android Studio Project
Open you project
Hope it will work.
sometimes, R file is not generated because of package name on android manifest is not match with package module that you have.
Is any wrong syntax or spelling in your xml?
Check your layout or any xml file.
Android Studio seems to have a caching issue with R.java occasionally. I rarely have a problem with this, but when I do, I actually open R.java (double press shift and type "R.java") or navigate to R.java under "app/build/generated/source" directory, opening the file and checking if the relevant XML id has been created. If it has, it forces Android Studio to now recognise the id's that are not being resolved. It's quick to try, and doesn't require clean and rebuild.
From your programs menu, open android studio. instead of opening your project from the recent files, select to open a project from your computer and then locate the path to your project. When all else fails, sometimes this works.
Also, try commenting out the support libraries from your gradle implementation, sync your project, and after sync fails comment them back in and sync again. (not sure if that's what you tried already when you said you messed with the gradle file)
In my case,
I am using
- Android Studio version 3.3.1 at home
- Android Studio version 3.2.1 at office
When i pulled projects to my office computer that are firstly created at my home computer ,
Android Studio can not resolved R file but runs application with no error. Because projects gradle and Android Studio version are incompatible.
Only thing that you sholud do, change the gradle version in project level gradle file
classpath 'com.android.tools.build:gradle:3.3.1'
to
classpath 'com.android.tools.build:gradle:3.2.1'
I was facing same issue,
first thought the issue might because of some xml file or naming of drawable resources incorrectly. After analysing, this case wasn't applicable to me.
So
Updating Android studio from older version 3.2 to newer version 3.3.2 along with new build tool version from SDK manager resolved this issue
for me.
I've tried invalidate cache and Restart AS with clean rebuild all the options but didn't work for me.
It says cannot resolve symbol, but it can run.
In my case, I just reload the needed *.jar files to the libs folder.
File >> invalidate caches/restart
Rebuild Project
Sync
Run
Works for me!
It looks like the library did not load my "imports" properly the first time.
That's why the import methods cannot be seen in my main_activity.xml.
This happened to me when I was going back and forth between different SDK versions.
Apparently SDK manager copied all the source files but it didn't finish cleanly. As a result I could compile and run my project just fine but IDE didn't recognize the SDK and reported all java symbols unresolved.
None of the above and other solutions in SO didn't work for me, but just uninstalling/reinstalling the specific SDK version did a job.
If you renamed your package (inside java folder), make sure you change your Manifest package name to the same
The only thing that worked for me was,
replacing,
import package_name.R
with
import package_name.*
simply go to project settings : settings.gradel and change the rootProject.name to your current name
rootProject.name = "write the project name here"
In trying to get the hang of Fragment, I imported into Android Studio 1.5.1 the unzipped folder FragmentBasics after extracting the downloaded file FragmentBasics.zip to that Folder.
Now I have Gradle problems and I have no clue what to do to be able to run the app. I don't know that the .zip file is from Eclipse as the message suggests.
I did move the folder FragmentBasics to C:\Users\Dov because of the space in "Google Drive" but got same error.
Gradle project sync failed . Basic functionality (e.g., editing, debugging) will not work properly.
Failed to sync gradle project 'FragmentBasics'
Error:Cause: failed to find target with hash string 'android-15' in: C:\Users\Dov\AppData\Local\Android\sdk

ECLIPSE ANDROID PROJECT IMPORT SUMMARY
Risky Project Location:
The tools should handle project locations in any directory. However,
due to bugs, placing projects in directories containing spaces in the
path, or characters like ", ' and &, have had issues. We're working to
eliminate these bugs, but to save yourself headaches you may want to
move your project to a location where this is not a problem.
C:\Users\Dov\Google Drive\AndroidStudioProjects\FragmentBasics

Replaced Jars with Dependencies:
The importer recognized the following .jar files as third party
libraries and replaced them with Gradle dependencies instead. This has
the advantage that more explicit version information is known, and the
libraries can be updated automatically. However, it is possible that
the .jar file in your project was of an older version than the
dependency we picked, which could render the project not compileable.
You can disable the jar replacement in the import wizard and try again:
android-support-v4.jar => com.android.support:support-v4:18.0.0
Moved Files:
Android Gradle projects use a different directory structure than ADT
Eclipse projects. Here's how the projects were restructured:
AndroidManifest.xml => app\src\main\AndroidManifest.xml
res\ => app\src\main\res\
src\ => app\src\main\java\
Next Steps:
You can now build the project. The Gradle project needs network
connectivity to download dependencies.
Bugs:
If for some reason your project does not build, and you determine that
it is due to a bug or limitation of the Eclipse to Gradle importer,
please file a bug at http://b.android.com with category
Component-Tools.
(This import summary is for your information only, and can be deleted
after import once you are satisfied with the results.)
I installed sdk 15 but then had problems with Gradle griping about
gradle-wrapper.properties file having a line with
gradle-2.8-all.zip that needed to be changed to
gradle-2.1-all.zip, so I edited gradle-wrapper.properties file to contain 2.1 instead of 2.8.
Message said after making change, re-import project. And it works.
Before importing I only removed following line from AndroidManifest.xml
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15" />
Worked with FragmentsBasics.zip in Android Studio 2.3.3
Why does Android Studio download gradle every time I try to import a new project?
Initially, I imported one gradle project for which Gradle 2.1 was auto-downloaded. Subsequently, for a second project import, it downloaded Gradle 1.10. Now again while importing a third project, it has downloaded Gradle 2.2.1.
What is happening?
Projects can declare which Gradle they require to run (see gradle.properties file in gradle directory in the root of the project).
Android Studio uses this information to download and run the right version (it's actually not Android Studio, it's the Gradle Wrapper running inside it). And it's a good thing.
What you can do?
Wait. Once you have the version downloaded in ~/.gradle directory, it will be used for any project declaring the same version. It's one-time cache.
Disable the usage of the wrapper when you import the project. I really recommend against it! You project might not build because of that.
Same happens to me.
The answer of JBaruch is allright.
1.- When you're opening a file on the option Gradle project: select the build.gradle that cames on your project
2.- Select the option "Use local grade distribution" and in Gradle home option; go and select in C:\Program Files\Android\Android Studio\gradle\gradle-2.2.1
It will not ask you to download it again (except if needs other version)
...well, here's what I normally do to speed up the initial build on opening a project (target):
1- open a project you already have working and open the file gradle-wrapper.properties a copy the following line (your project most likely will have a different version):
distributionUrl=https://services.gradle.org/distributions/gradle-6.7-bin.zip
2- paste it and replace the code on the same file on the target project
3- open the file build.gradle (project code) from a project you already have working and copy the following classpath, (again, your project most likely will have a different version)
dependencies {
classpath 'com.android.tools.build:gradle:4.2.0-alpha15'
// ...
}
4- paste it on the same file on the target project
This way you can speed up the build of the target project while avoiding the usual 100Mb or so Gradle download.
Basically it downloads the Gradle build files for your current project according to its version and this whole work is done by your gradle wrapper which actually looks towards the basic requirement for your project and downloads the files according to that so whenever you are going to use any another projects of same version or with same requirements then it will not download any additional file at that time.Its just a one time shot!!!!
It usually downloads the Gradle updated version & and external dependencies for each project rather than fetching it from the cache.
So follow these steps:-
Go to settings
Search for Gradle
Untick Download External Dependencies Option.
