为什么我触摸停止按钮，不幸关闭我的应用程序

这是我的代码，我按下停止按钮后应用程序自动关闭。我调试并跟踪到“myAudioRecorder.stop（）”，它有“exception（s）_during_the_evaluation”异常。我不知道如何解决它。为什么我触摸停止按钮，不幸关闭我的应用程序

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(); 

}

请先添加logcat –

首先添加一个条件，然后停止myaudiorecoring不为空的记录。 – Kishan

您是否检查过MediaRecorder处于有效状态？ [来自参考资料]（http://developer.android.com/reference/android/media/MediaRecorder.html#stop（））：'请注意，如果没有有效的音频/视频数据有意地将RuntimeException抛出到应用程序当stop（）被调用时被接收到。并且'stop（）...抛出IllegalStateException \t如果在start（）之前调用它' –

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

你插入WRITE_EXTERNAL_STORAGE和RECORD_AUDIO许可到应用程序的清单文件？

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

阅读关于Audio Capture的官方教程。

OP使用'AudioRecorder'录制声音。他/她没有尝试读取文件，他们正在尝试写入文件。尝试打开文件进行写入时会抛出'FileNotFoundException' - 它们需要具有'WRITE_EXTERNAL_STORAGE'权限。 – Squonk

@Squonk但提供的logcat不包含有关写入的任何异常。 – Bishan

当试图打开文件进行读取时，不仅仅会引发'FileNotFoundException' - 如果操作失败，尝试打开新文件进行写入操作时也会引发FileNotFoundException。混淆吧？严重的是，搜索stackoverflow，你会发现有关它的问题。 – Squonk

检查了这一点首先：

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

和你插入许可，原因是其是说，文件清单文件中没有发现？

确保您的刻录机被停止只有当录制过程中其他你能处理这样也：

 if (audio_recorder != null) { 

      // Clear recorder configuration 
      audio_recorder.reset(); 

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

     }

，并且确保你已经在你的清单文件中添加了所有所需的权限。

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