Android Permissions won't work

Question

I'm trying to record a sound in java in android but the app crashes with this exception:

E/AndroidRuntime: FATAL EXCEPTION: Timer-0
Process: com.example.mathieu.telefony1, PID: 31353
java.lang.RuntimeException: setAudioSource failed.

But it is very strange, because I added it to the AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.RECORD_AUDIO"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<application...

and here is my code to record a sound:

MediaRecorder mr = new MediaRecorder();

File file = new File(OUTPUT_FILE);

try {



    mr.setOutputFile(OUTPUT_FILE);

    mr.setAudioSource(MediaRecorder.AudioSource.MIC);

    mr.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);

    mr.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);

    mr.prepare();

    mr.start();

    Thread.sleep(1000);

    mr.stop();





} catch (IOException e) {

    e.printStackTrace();

} catch (InterruptedException e) {

    e.printStackTrace();

}

Above API level 23 you will be given permission pragmatically like:

 private static final int PERMISSION_REQUEST_CODE = 1;

 if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {

    if (checkSelfPermission(Manifest.permission.SEND_SMS)
            == PackageManager.PERMISSION_DENIED) {

        Log.d("permission", "permission denied to SEND_SMS - requesting it");
        String[] permissions = {Manifest.permission.SEND_SMS};

        requestPermissions(permissions, PERMISSION_REQUEST_CODE);

    }
}
