java.lang.StackOverflowError：android studio上的堆栈大小为8MB。 怎么解决？

Question

正如我在android studio中运行的应用程序遇到了这个问题。

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.user.brain_storming, PID: 11742
    java.lang.StackOverflowError: stack size 8MB
        at com.example.user.brain_storming.MusicService$1.onError(MusicService.java:48)
        at com.example.user.brain_storming.MusicService$1.onError(MusicService.java:48)

我已经检查了第48行的代码

    mPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {

        public boolean onError(MediaPlayer mp, int what, int
                extra) {

            onError(mPlayer, what, extra);
            return true;
        }
    });

我知道如何解决它，我已经开始启用高级分析，因为我引用了这个网站。 但它不起作用=（

下面的代码是我的音乐服务代码

问题：你正在调用错误的onError方法。 你必须在调用onError的MusicService代替。

解决方案：更改您的代码

mPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {

    public boolean onError(MediaPlayer mp, int what, int
            extra) {
        onError(mPlayer, what, extra);
        return true;
    }
});

至

mPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {

    public boolean onError(MediaPlayer mp, int what, int
            extra) {
        // Calling onError of MusicService instead this onError method.
        MusicService.this.onError(mPlayer, what, extra);
        return true;
    }
});
