为什么我触摸停止按钮，我的应用程序不幸关闭

时间：2014-01-20 04:12:36

标签： android

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

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

3 个答案:

答案 0 :(得分：2)

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

您是否已将WRITE_EXTERNAL_STORAGE和RECORD_AUDIO权限插入应用程序的清单文件中？

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

阅读有关Audio Capture的官方教程。

答案 1 :(得分：0)

首先检查一下：

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

并且您是否已插入清单文件的权限，因为它说该文件未找到？

答案 2 :(得分：0)

确保录制器仅在录制正在进行时停止，否则您也可以这样处理：

        if (audio_recorder != null) {

            // Clear recorder configuration
            audio_recorder.reset();

            // Release the recorder object
            audio_recorder.release();
            audio_recorder = null;

        }

并确保您已在清单文件中添加了所有必需的权限。

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