今天在调用MediaRecorder.stop()，报错了，java.lang.RuntimeException: stop failed.
E/AndroidRuntime(7698): Cause by: java.lang.RuntimeException: stop failed. E/AndroidRuntime(7698): at android.media.MediaRecorder.stop(Native Method) E/AndroidRuntime(7698): at com.tintele.sos.VideoRecordService.stopRecord(VideoRecordService.java:298)
报错代码如下：
if (mediarecorder != null) {
mediarecorder.stop();
mediarecorder.release();
mediarecorder = null;
if (mCamera != null) {
mCamera.release();
mCamera = null;
}
}
stop()方法源代码如下：
/**
* Stops recording. Call this after start(). Once recording is stopped,
* you will have to configure it again as if it has just been constructed.
* Note that a RuntimeException is intentionally thrown to the
* application, if no valid audio/video data has been received when stop()
* is called. This happens if stop() is called immediately after
* start(). The failure lets the application take action accordingly to
* clean up the output file (delete the output file, for instance), since
* the output file is not properly constructed when this happens.
*
* @throws IllegalStateException if it is called before start()
*/
public native void stop() throws IllegalStateException;
源代码中说了：Note that a RuntimeException is intentionally thrown to the application, if no valid audio/video data has been received when stop() is called. This happens if stop() is called immediately after start().
现在，在mediarecorder.stop();这一句报错了，现在在mediarecorder.stop();这句之前加几句就不会报错了
mediarecorder.setOnErrorListener(null);
mediarecorder.setOnInfoListener(null);
mediarecorder.setPreviewDisplay(null);
改后代码如下：
if (mediarecorder != null) {
//added by ouyang start
try {
//下面三个参数必须加，不加的话会奔溃，在mediarecorder.stop();
//报错为：RuntimeException:stop failed
mediarecorder.setOnErrorListener(null);
mediarecorder.setOnInfoListener(null);
mediarecorder.setPreviewDisplay(null);
mediarecorder.stop();
} catch (IllegalStateException e) {
// TODO: handle exception
Log.i("Exception", Log.getStackTraceString(e));
}catch (RuntimeException e) {
// TODO: handle exception
Log.i("Exception", Log.getStackTraceString(e));
}catch (Exception e) {
// TODO: handle exception
Log.i("Exception", Log.getStackTraceString(e));
}
//added by ouyang end
mediarecorder.release();
mediarecorder = null;
if (mCamera != null) {
mCamera.release();
mCamera = null;
}
}
