I know that an embedded emulator has been introduced in Android Studio 4.1+. I am not able to see options to enable it.
The changelog says that you need to enable it manually. Follow these steps:
Steps
Open Android Studio and goto Preference / Settings
Expand the Tools tab and goto emulator
Check 'Launch in a tool window'
Apart from the previous, if you dont't see the emulator tab in IDE:
I found that adding a "<module fileurl="file://$PROJECT_DIR$/android/..." line in Project directory, file .idea/modules.xml the tab appears:
<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
<component name="ProjectModuleManager">
<modules>
<module fileurl="file://$PROJECT_DIR$/renal_calc_flutter.iml" filepath="$PROJECT_DIR$/renal_calc_flutter.iml" />
<module fileurl="file://$PROJECT_DIR$/android/renal_calc_flutter_android.iml" filepath="$PROJECT_DIR$/android/renal_calc_flutter_android.iml" />
</modules>
</component>
</project>
I started to learn Android Studio. I try to echo out simple "Hello World":
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="#+id/activity_main"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="16dp"
android:paddingBottom="16dp"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</RelativeLayout>
but when I clicked "design" view, this error is showing?
Design editor is unavailable until a successful build
How can I fix this error.
I just noticed that my xml code is causing error. Is that why this may be not working?
Go to File > Sync Project with Gradles Files.
Quit the Android Studio ( not close the project Quit the Android Studio) then open the project and go to Android Studio > Build > Clean Project
Then
Android Studio > File > Sync Project with Gradles Files as the pic below
If your problem still exists then click the Install build tool as the pic below and then
Android Studio > File > Sync Project with Gradles Files
None of the above worked for me. what worked for me is to go to File -> Invalidate Caches / Restart
I faced same issue even after rebuilding my project multiple times successfully. I closed the project and re-opened, issue resolved.
First, find your build.gradle in your all modules in project, include app/build.gradle. Find the compileSdkVersion inside android tag, in this case, compile sdk version is 30:
Next, open SDK Manager > SDK Platforms, check for install SDK versions that there modules using, then apply to install selected platforms.
After installed, go to menu File > Sync project with Gradle files....
This issue often appear when project has many modules, each module use different compile SDK version, so app may be able to build but IDE have some issue while processing your resources.
Simply restart the Android Studio. In my case, I was offline before starting the Android Studio, but online when I did restart.
Do this
Build -> Rebuild Project
Install missing plataform and sync project
Go online before starting android studio. Then go file->New project
Follow onscreen steps. Then wait It will download the necessary files over internet. And that should fix it.
I got this problem after i added a line in my build.gradle file.
compile 'com.balysv:material-ripple:1.0.2'
Solution:
I changed this line to
implementation 'com.balysv:material-ripple:1.0.2'
and then pressed sync again.
Tada! all was working again.
In my case, it was because it didn't like that I left the minSDK and targeSdk in the manifest. Go figure.
just click file in your android studio
then click Sync Project with Gradle Files..
if it won't work,
click Build
click Clean Project.
it always work for me
The Android SDK Platform API Level that the project requires for targetSdkVersion may not exist.
Check the console of the Event Log tab of the IDE to see any errors eg. of the following type:
Gradle sync failed:
com.android.tools.idea.gradle.project.sync.idea.issues.SdkPlatformNotFoundException:
Module: 'common' platform 'android-29' not found.
Then install some API Level (29) in SDK Manager -> SDK Platforms and finally Sync again.
Edit you xml file in Notepad++ and build it again. It's work for me
I have the latest Android Studio 3.6.1 and yet couldn't build a simple 'Hello World' app as documented here "https://codelabs.developers.google.com/codelabs/android-training-hello-world/index.html?index=..%2F..%2Fandroid-training#3".
I applied various steps discussed above including the 2 most viable options which should have really solved this issue,
'File->Sync Project with Gradle Files' and
'File->Invalidate Caches/Restart' but to no avail.
Even though, I suspect standard answer should be one of these 2 options only for most, but for me the resolution came only after I went inside the 'File->Project Structure' and checked my SDK versions configured!
Android Studio and Gradle were using different JDK versions and locations.
Android Studio: C:\Program Files\Java\jdk1.8.0_241
Gradle: C:\Program Files\Java\jdk-13.0.2
I had previously defined my JAVA_HOME environment variable by downloading latest JAVA SDK on my own from ORACLE website. Where Gradle was using the %JAVA_HOME% JAVA SDK version and Android Studio the built in SDK which came along with Android Studio.
Once I switched both to versions JDK 1.8.* (Any version as long as it is JDK 1.8. for that matter*) then simple 'File->Synch...' option worked perfectly fine for me!
Good luck the solution is in between one of these 2 options only if you are stuck, just ensure you validate JDK versions being referred to!
there are different solutions to this problem but I at the first u have to check to (build.gradle) maybe it empty. this especially if u downloaded code, not u created
and u will find just this line "// Top-level build file where you can add configuration options common to all sub-projects/modules."
in this case, u need to open a new project and make copy-paste.then check the SDK and other settings.finally u have to sync
In my case, the Windows Firewall was blocking Android Studio (i.e. java.exe from Android Studio's jre/bin folder) from connecting to sites and downloading data. After Windows asked me if I wanted to allow the app through the firewall, I had to do a manual sync File -> Sync project with gradle files. After that, things were still disfunctional, a manual download of an SDK version 28 was necessary from Tools -> SDK Manager.
If you are in corporate setting where there is a proxy server, double check your proxy settings.
Go File -> Settings
Search for Proxy.
Fill out as appropreate.
Test connection.
If you think you fat-fingered the password, there is a Clear passwords button you can click to where you can re-enter your creds. HTH
I had tried to change SDK Version:
Check below image: In that I changed 27 from Android P
I have the 2.2.3 version of Android Studio on Ubuntu and I clicked "Ignore this update" by mistake. How can I apply the update without having to reinstall Android Studio?
I found the answer below, but I can't find the other.xml neither updates.xml files:
Removing Ignored Android Studio (or Intellij) Update Builds
In Linux go to ~/.AndroidStudio2.2/config/options folder and edit updates.xml.
Remove ignoredBuildNumbers block.
In my updates.xml file, it was like below. Removing this block solved it.
<ignoredBuildNumbers>
<item value="162.3764568" />
</ignoredBuildNumbers>
On my MacOS it was present on :
~/Library/Preferences/AndroidStudio2.2/options/updates.xml
And I removed the following lines
<ignoredBuildNumbers>
<item value="162.3764568" />
</ignoredBuildNumbers>
I'm switching our project from Eclipse to Android Studio. I had the proxy settings in our project's gradle.properties file, but then I realized that I have to check this file into version control and it would expose my passwords.
I moved these settings to [USER_HOME]/.gradle/gradle.properties and it works fine, except for Android Studio asks at every gradle sync if I want to copy the configuration back to the project folder.
How do I turn this notification off?
In ${idea.config.path}/options/options.xml file, there is a /application/component[#name='PropertiesComponent']/property[#name='show.do.not.copy.http.proxy.settings.to.gradle'] element node.
If its value is true(default value), "Proxy Settings" dialog will be shown normally;
<property name="show.do.not.copy.http.proxy.settings.to.gradle" value="true" />
if its value is false, Android Studio will "do not ask again".
<property name="show.do.not.copy.http.proxy.settings.to.gradle" value="false" />
Tips:
Don't forget to click Synchronize(Ctrl+Alt+Y) button or File->Synchronize, after change this file.
idea.config.path is set in android-studio\bin\idea.properties, whose default value is ${user.home}/.AndroidStudio${version}/config
Tested with Android Studio 1.4 Preview 2 # Win8.1 X64
In 1.3 version of Android studio there is a checkbox "do not ask again". And that exactly is the problem I'm having. I've checked it because everything was functioning OK without it but now I'd like to bring that dialog back as for the past couple of days the projects don't compile because gradle can not resolve new dependencies.
This setting <property name="show.do.not.copy.http.proxy.settings.to.gradle" value="true" /> could also be located in your project's folder in the file .idea\workspace.xml.
I try to run Butterknife project samples on Android studio 1.2 and keep getting that issue :
"Error:Android Source Generator: [butterknife-sample] AndroidManifest.xml file not found"
If I try to run the SimpleActivity, same issue : AndroidManifest.xml doesn't exist or has incorrect root tag.
Any idea
