Android 开始新活动时的ANR

嗨，我在屏幕上显示了3秒钟，然后我开始了新的活动，但在安卓5.0上，有一个黑屏几乎持续了10秒，而且是ANR。这是活动中显示3秒钟的所有代码：

private static final ScheduledExecutorService worker =
        Executors.newSingleThreadScheduledExecutor();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Crashlytics.start(this);
    setContentView(R.layout.splash_fragment);
    Runnable task = new Runnable() {
        public void run() {
            startActivity(new Intent(SplashActivity.this, MainActivity.class));
            finish();
        }
    };
    worker.schedule(task, 3, TimeUnit.SECONDS);
}

以及来自logcat的日志：

Activity destroy timeout for ActivityRecord
I/InputDispatcher(  725): Application is not responding: AppWindowToken
It has been 5005.0ms since event, 5003.6ms since wait started.  
Reason: Waiting because no window has focus but there is a focused application that may eventually add a window when it     finishes starting up.
I/WindowManager(  725): Input event dispatching timed out sending to application AppWindowToken
 Reason: Waiting because no window has focus but there is a focused application that may eventually add a window when     it finishes starting up.

我做错了什么？我怎样才能修复它？

为什么要花很长的时间，而你有一个简单的过程。正如@Chen在上面所评论的，您可以像这样启动

mainacivity

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        startActivity(new Intent(SplashActivity.this, MainActivity.class));
        finish();               
    }
}, 3000);

您是否尝试使用

Handler.postDelayed（Runnable r，long delaymilis）

？为什么显示启动屏幕？您是否尝试使用

Handler.postDelayed（Runnable r，long delaymilis）
