I got an app to read pdf files it works fine until i installed android 12 on my device.
Manifest:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:requestLegacyExternalStorage="true">
...
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" tools:remove="android:maxSdkVersion" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:remove="android:maxSdkVersion"
tools:ignore="ScopedStorage" />
Permission:
private static final int REQUEST_PERMISSIONS = 20;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.permissionactivity_main);
// Permission einholen
PermissionActivity.super.requestAppPermissions(new
String[]{Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE}, R.string
.runtime_permissions_txt
, REQUEST_PERMISSIONS);
}
@Override
public void onPermissionsGranted(int requestCode) {
startActivity(new Intent(PermissionActivity.this, MainActivity.class));
finish();
}
And the Code :
File myFile2 = new File(Environment.getExternalStorageDirectory().getPath()+"/FploData/");
if (!myFile2.exists()) {myFile2.mkdir();} // works with Android 12
File lister = myFile2.getAbsoluteFile();
Log.e("file2: ", String.valueOf(lister));
File[] files = myFile2.listFiles();
Log.e("file length: ", String.valueOf(files.length));
files.length returns 0 but the directory isn´t empty. The Code worked fine until i updated my Device from Android 11 to 12. I assume there is something wrong with the permission. Can someone help?
