Android-密钥调度超时

在我的Android应用程序中,我遇到了一个非常奇怪的崩溃,当我按下UI上的一个按钮(图片)时,整个应用程序都冻结了,几秒钟后,我看到可怕的强制关闭对话框出现了。

下面是日志中打印的内容:

findViewById(R.id.endcallimage).setOnClickListener(new OnClickListener() {
                    public void onClick(View v) {
                        mNotificationManager.cancel(2);

                        Log.d("Handler", "Endcallimage pressed");

                        if(callConnected)
                        elapsedTimeBeforePause = SystemClock.elapsedRealtime() - stopWatch.getBase();

                        try {
                            serviceBinder.endCall(lineId);
                        } catch (RemoteException e) {
                            e.printStackTrace();
                        } 
                            dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.FLAG_SOFT_KEYBOARD));
                            dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
                    }
            });     

如果我评论如下,按下按钮(图像)不会导致崩溃:

try {
      serviceBinder.endCall(lineId);
    } catch (RemoteException e) {
      e.printStackTrace();
    } 

上面的代码通过应用程序的几个级别向下调用并进入本机层(NDK),通过几个对象的调用是否会导致强制关闭?这似乎不太可能,因为其他几个按钮做同样没有问题。

本地层呢?我用NDK构建的一些代码会导致这个问题吗?

关于这个问题的起因还有什么其他的想法吗?
