Build failed error: cannot find symbol if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R)

Question

I tried building my ionic app after development; but in the process the following errors surfaced:

C:\incidentApp\platforms\android\app\src\main\java\com\moust\cordova\videoplayer\VideoPlayer.java:123: error: cannot find symbol if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) { ^ > Task :app:compileDebugJavaWithJavac symbol: variable R location: class VERSION_CODES C:\incidentApp\platforms\android\app\src\main\java\com\moust\cordova\videoplayer\VideoPlayer.java:124: error: cannot find symbol dialog.getWindow().getInsetsController().hide(WindowInsets.Type.statusBars()); ^ symbol: variable Type location: class WindowInsets C:\incidentApp\platforms\android\app\src\main\java\com\moust\cordova\videoplayer\VideoPlayer.java:124: error: cannot find symbol dialog.getWindow().getInsetsController().hide(WindowInsets.Type.statusBars()); ^ symbol: method getInsetsController() location: class Window Note: Some input files use or override a deprecated API.

I'd tried everything(removing of android package and re-installing) I could lay my hands on but still not working.

Below is my build.gradle

 project.ext {
      defaultBuildToolsVersion="29.0.3" //String
      defaultMinSdkVersion=22 //Integer - Minimum requirement is Android 5.1
      defaultTargetSdkVersion=28 //Integer - We ALWAYS target the latest by default
      defaultCompileSdkVersion=29 //Integer - We ALWAYS compile with the latest by default
    }

Answer 1

Simply upgrade the compileSdkVersion and targetSdkVersion to 31 in your android/app/build.gradle file.

Answer 2

Updated-: make sure you set compileSdkVersion in your android/app/build.gradle file to 31

Old-: I encounter this error while using the Geolocator plugin in the flutter app. to Solve this error you have to open LocationMapper.java (you can find this path in your Debug console). and remove this part

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S)

and also make sure your android compile version is 30 (For GeoLocator Build.gradle)

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
      position.put("is_mocked", location.isMock());
   } 

Answer 3

Build.VERSION_CODES.R only exists in API 30, but you're compiling with API 29.

The compileSdkVersion should be set to 30 if you want to use Build.VERSION_CODES.R.

Update for cordova-android@10

As of cordova-android@10, compileSdkVersion has been removed android-targetSdkVersion is unified to set both the target & compile SDK versions, so that they always remain consistent.

Update for cordova-android@11

As of cordova-android@11, the ability to independently set the compile SDK and target SDK separately has returned.

Just like before, use android-targetSdkVersion preference to set the Target SDK. Use android-compileSdkVersion preference to set the Compile SDK.

Like before, the target SDK will default to a particular version that cordova-android has been tested with. Cordova-android@11 uses API 32 by default. The compile SDK will default to the configured Target SDK.

Generally speaking, the target and compile should match, but with cordova-android@11 (and 9), you can set the compile SDK higher while keeping the target SDK lower, which can be useful for things that requires the API codes for compatibility checks.
