android - 为什么我触摸停止按钮，不幸的是我的应用程序关闭了

Question

这是我的代码，应用程序在我触摸停止按钮后自动关闭。我调试并跟踪到“myAudioRecorder.stop()”，它有异常“error(s)_during_the_evaluation”。我还不知道如何修复它。

public void stop(View view){

  myAudioRecorder.stop();
  myAudioRecorder.release();
  myAudioRecorder  = null;
  stop.setEnabled(false);
  play.setEnabled(true);
  Toast.makeText(getApplicationContext(), "Audio recorded successfully",
  Toast.LENGTH_LONG).show();

}

Logcat 结果

Answer 1

java.io.FileNotFoundException: /storage/sdcard0/myrecording.3gp: open failed: EACCES (Permission denied)

您是否已将 WRITE_EXTERNAL_STORAGE 和 RECORD_AUDIO 权限插入到应用程序的 list 文件中？

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