ANR beim Starten der Audioaufnahme im Hintergrunddienst

Ich versuche eine App zu erstellen, die Audio im Hintergrund aufzeichnet. Ich benutze Service Klasse für diesen Zweck. Da ich meine UI Thread nicht blockieren möchte, habe ich in meiner Service-Klasse eine HandlerThread erstellt, um den Aufzeichnungsvorgang durchzuführen. Wenn ich versuche, die Service auszuführen, löst meine App ANR (Application Not Responding) error. Ich kann nicht herausfinden, wie meine UI Thread blockiert wird. Erwähnenswert ist auch, dass ich einen CountUp Timer erstellt habe, der auf meinem UI Thread läuft.ANR beim Starten der Audioaufnahme im Hintergrunddienst

ist hier mein Code:

public class AudioRecorderService extends Service { 
    private Looper mLooper; 
    private AudioRecorderHandler mAudioRecorderHandler; 
    private MediaRecorder mAudioRecorder; 


    public AudioRecorderService() { 
    } 


    private final class AudioRecorderHandler extends Handler { 

     private String fileName; 

     public AudioRecorderHandler(Looper looper) { 
      super(looper); 
     } 

     @Override 
     public void handleMessage(Message msg) { 

      fileName = Environment.getDataDirectory().getAbsolutePath() + "/" + "test.mp4"; 

      mAudioRecorder = new MediaRecorder(); 
      mAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); 
      mAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); 
      mAudioRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC); 
      mAudioRecorder.setAudioEncodingBitRate(256); 
      mAudioRecorder.setAudioChannels(1); 
      mAudioRecorder.setAudioSamplingRate(44100); 
      mAudioRecorder.setOutputFile(fileName); 

      try { 
       mAudioRecorder.prepare(); 
       mAudioRecorder.start(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 

     } 
    } 


    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 

     Toast.makeText(this, "Recording Started", Toast.LENGTH_LONG).show(); 

     Message msg = mAudioRecorderHandler.obtainMessage(); 
     msg.arg1 = startId; 

     mAudioRecorderHandler.sendMessage(msg); 

     return START_REDELIVER_INTENT; 
    } 

    @Override 
    public IBinder onBind(Intent intent) { 
     // TODO: Return the communication channel to the service. 
     throw new UnsupportedOperationException("Not yet implemented"); 
    } 

    @Override 
    public void onCreate() { 

     android.os.Debug.waitForDebugger(); 

     HandlerThread thread = new HandlerThread("AudioRecorder", Process.THREAD_PRIORITY_BACKGROUND); 
     thread.start(); 

     mLooper = thread.getLooper(); 
     mAudioRecorderHandler = new AudioRecorderHandler(mLooper); 
    } 

    @Override

     if (mAudioRecorder != null) { 
      mAudioRecorder.stop(); 
      mAudioRecorder.release(); 
      mAudioRecorder = null; 
     } 

     Toast.makeText(this, "Recording Done", Toast.LENGTH_LONG).show(); 

     mLooper.quit(); 
     mLooper.getThread().interrupt(); 

    } 
}

erstellen Datei auf Ihrem Weg passieren sie dann auf den Player

File root = new File(Environment.getDataDirectory().getAbsolutePath() + "/" + "recordings"); 
if (!root.exists()) { 
    root.mkdirs();   
    } 

fileName = root.getPath().toString();

Und wenn Sie gegen API kompiliert werden 23 (6.0), dann haben Sie auch Berechtigungen Laufzeit erhalten.

tat ich das, aber ich bin immer noch ANR .... @SohailZahid –

@VaibhavAgarwal Welche API Version Sie verwenden? –

ich es auf API-Ebene leite 17 –

Was ist der Mittelwert von "android.os.waitForDebugger()"? Es wird Ihren Thread (Ihren Hauptthread) schlafen, bis ein Debugger angeschlossen ist.

Ich denke, es ist das Problem.
