App直接飞掉

问题：

Native Looper 初始化失败

根据日志和APP操作查找Looper.preare();出现的地方

    public static void showToast(final String toast, final int showTimeFlag, final Context context)
    {
        new Thread(new Runnable()
        {
            @Override
            public void run()
            {
                Looper.prepare();
                Toast.makeText(context, toast, showTimeFlag).show();
                Looper.loop();
            }
        }).start();
    }

修改：

    public static void showToast(final String toast, final int showTimeFlag, final Context context)
    {
        new Thread()
        {
            public void run()
            {
                System.out.println("Start Looper...");
                // Prepare looper
                Looper.prepare();

                // Register Queue listener hook
                MessageQueue queue = Looper.myQueue();
                queue.addIdleHandler(new IdleHandler()
                {
                    int    mReqCount    = 0;

                    @Override
                    public boolean queueIdle()
                    {
                        if (++mReqCount == 2)
                        {
                            // Quit looper
                            System.out.println("Looper.myLooper().quit()");
                            Looper.myLooper().quit();
                            return false;
                        } else
                            return true;
                    }
                });

                // Show Toast- will be called when Looper.loop() starts
                Toast.makeText(context, toast, showTimeFlag).show();
                // Start looping Message Queue- Blocking call
                Looper.loop();
                System.out.println("It appears after Looper.myLooper().quit()");
            }
        }.start();
    }

and then got this log:
