App funktioniert nicht auf neues Gerät

Question

Ich habe eine App, die auf dem Samsung S7 und der Tribute funktioniert. Ich habe es kürzlich auf dem Samsung S5 ausprobiert und es ist abgestürzt. Ich bekomme das:

Es stürzt ab, wenn ich den Aufnahmeknopf drücke. Die Schaltfläche zeichnet auditorische Informationen mit audioRecord und dem Beschleunigungssensor auf. Auf der Tribute und SAMSUNG S7 funktioniert der gesamte Code ohne Probleme.

public void Recordbutton(View view) { 

    if (recordbuttonstatus) { 
     playBtn.setEnabled(true); 
     recordbuttonstatus = false; 
     startBtn.setText(getString(R.string.stoprecording)); 
     sensorManager.registerListener(accelListener, sensor, SensorManager.SENSOR_DELAY_NORMAL); 

     Thread accelerometerrecord = new Thread(new Runnable() { 

      @Override 
      public void run(){ 
       File accoutputFile = new File(Environment.getExternalStorageDirectory(), "accelerometervals.txt"); 
       try { 
        accoutputFile.createNewFile(); 
       } catch (IOException e){ 
        e.printStackTrace(); 
       } 
       try { 
        writer = new FileWriter(accoutputFile, false); /*When false, the file is overwritten, when true, the file is appended.*/ 
       } catch (IOException e) { 
        Log.e(LOG_TAG2, "failed"); 
       } 
      } 
     }); 

     accelerometerrecord.start(); 

     Thread recordThread = new Thread(new Runnable() { 

      @Override 
      public void run() { 
       File file = new File(Environment.getExternalStorageDirectory(), "test.pcm"); 

       try { 
        file.createNewFile(); 

        OutputStream outputStream = new FileOutputStream(file); 
        BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(outputStream); 
        DataOutputStream dataOutputStream = new DataOutputStream(bufferedOutputStream); 

        int minBufferSize = AudioRecord.getMinBufferSize(samplingFreq, 
          AudioFormat.CHANNEL_IN_MONO, 
          AudioFormat.ENCODING_PCM_16BIT); 

        short[] audioData = new short[minBufferSize]; 

        AudioRecord audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, 
          samplingFreq, 
          AudioFormat.CHANNEL_IN_MONO, 
          AudioFormat.ENCODING_PCM_16BIT, 
          minBufferSize); 

        audioRecord.startRecording(); 

        while (!recordbuttonstatus) { 
         int numberOfShort = audioRecord.read(audioData, 0, minBufferSize); 
         for (int i = 0; i < numberOfShort; i++) { 
          dataOutputStream.writeShort(audioData[i]); 
         } 
        } 

        audioRecord.stop(); 
        dataOutputStream.close(); 

       } catch (IOException e) { 
        e.printStackTrace(); 
       } 

      } 

     }); 

     recordThread.start(); 

    } else { 
     startBtn.setText(getString(R.string.newrecording)); 
     recordbuttonstatus = true; 
     sensorManager.unregisterListener(accelListener); 

    } 
} 

Answer 1

prüfen AndroidManifest.xml für diese Berechtigungen

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

und in Ihrer Tätigkeit Griff für Eibisch Laufzeit Erlaubnis.

Überprüfen Sie die Audioaufnahmeberechtigung und schreiben Sie eine externe Speicherberechtigung, bevor Sie die Datei auf die SD-Karte schreiben.

 if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { 
     ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.RECORD_AUDIO}, REQUEST_CODE); 
     }else { 
     //Write Data to SD Card 
    } 

und überschreiben onRequestPermission Methode der Aktivität.

@Override 
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
      switch (requestCode) { 
       case REQUEST_CODE: { 
       if (grantResults[0] != PackageManager.PERMISSION_GRANTED||grantResults[1] != PackageManager.PERMISSION_GRANTED) { 
         this.finish(); 
         Toast.makeText(this, "Permission is required.", Toast.LENGTH_LONG).show(); 
       } 
     return; 
    } 
    default: 
     super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
     break; 

     }
