新しいデバイスでアプリが動作しない

Question

Samsung S7とTributeで動作するアプリがあります。私は最近サムスンS5でそれを試して、クラッシュしました。私はこれを得る：

私はレコードボタンを押すとクラッシュする。このボタンは、audioRecordと加速度計を使用して聴覚情報を記録します。 TributeとSAMSUNG S7では、コード全体が問題なく動作します。

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); 

    } 
}

これらの権限の確認AndroidManifest.xml

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

とマシュマロのためのあなたの活動ハンドル実行時のアクセス許可インチ

private int REQUEST_CODE = 1; 

SDカードにファイルを書き込む前に、オーディオの書き込み許可と書き込み外部記憶権を確認してください。

 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 
    } 

オーバーライドonRequestPermissionアクティビティの方法。

@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; 

     }
