Android的媒体播放器强制力接近onquit [英] Android mediaPlayer causing force close onquit

问题描述

我的code是力量，只要我打的后退按钮离开活动闭幕。这里是。
我认为它的作用是比较自我解释。在调用时，它显示了一些文本加一个按钮，拍了拍当启动录音播放。当有人点击后退按钮，它应该回到previous活动，并停止录制。感谢您帮助我！

 公共类ToBeOrNot延伸活动{@覆盖
保护无效的onCreate（捆绑savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_to_be_or_not）;    }
MediaPlayer的媒体播放器;公共无效反应（查看视图）{
    媒体播放器= MediaPlayer.create（ToBeOrNot.this，R.raw.achord）;
    mediaPlayer.start（）;
}
保护无效的onStop（）{
mediaPlayer.release（）;
媒体播放器= NULL;
}
@覆盖
公共布尔onCreateOptionsMenu（菜单菜单）{
//充气菜单;如果是present这增加了项目操作栏。
//getMenuInflater().inflate(R.menu.activity_to_be_or_not，菜单）;
//与ShareActionProvider找到菜单项
返回true;
}}
 

解决方案

请提供登录猫错误日志，否则它的痛苦看看什么是错。

不过，我想你需要。

 上的onPause媒体播放器，通话停止（）（）
 

如果你想让它继续玩，那么你需要使用的服务。

My code is force closing as soon as I hit the back button to leave the activity. Here it is. I think what it does is relatively self explanatory. When called, it shows some text plus a button that when tapped starts a recording playing. When someone hits the back button, it should go back to the previous activity and stop the recording. Thanks for helping me!

public class ToBeOrNot extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_to_be_or_not);

    }
MediaPlayer mediaPlayer;

public void react(View view) {
    mediaPlayer = MediaPlayer.create(ToBeOrNot.this, R.raw.achord);
    mediaPlayer.start(); 
}
protected void onStop(){
mediaPlayer.release();
mediaPlayer = null;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
//getMenuInflater().inflate(R.menu.activity_to_be_or_not, menu);
// Locate MenuItem with ShareActionProvider
return true;
}

}

解决方案

Please provide log-cat error logs, otherwise its pain to look whats wrong.

But i guess you need to.

call stop() on media player in onPause()

If you want it to keep playing then you need to use service.
