安卓第一行代码学习 The application may be doing too much work on its main 问题。求助

[皆灾]

最近在学习大神的第一行代码，发现总是提示The application may be doing too much work on its main thread.这个错误。开始没太在意，因为就安卓模拟器的运行来说，有些小例子是可以测试的。但是最近看到了返回数据在logcat中看，但是由于提示The application may be doing too much work on its main thread.这个错误，总是不能看到logcat的值

这是logcat提示。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.first_layout);
Button button1 = (Button) findViewById(R.id.button_1);
button1.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
Intent intent = new Intent(FirstActivity.this,SecondActivity.class);
startActivityForResult(intent,1);
}
});
}
这是FirstActivity中的更改

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_layout);
Button button2 =(Button) findViewById(R.id.button_2);
button2.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v){
Intent intent = new Intent();
intent.putExtra("data_return","Hello FirstActivity");
setResult(RESULT_OK,intent);
finish();
}
});
}
这是SecondActivity中的更改。

这个例子郭霖大神给出的打印信息是
com.example.activity D/FirstActivity：Hello FirstActivity


来论坛找了很多提示The application may be doing too much work on its main thread.这种的错误，发现都是很大规模的程序，那我这种小例子的测试怎么会提示这种呢？费解。求大腿指教一二，感激不尽。

你看看你的Activity有没有定义跳转动画。。 最好把onActivityResult 的代码也贴下

[隔壁村的二傻子]

这些看起来，貌似，没毛病

[moonFY]

你贴出来的代码没有问题，问题在你没贴出来的代码中

[sadyYang]

不要在主线程做耗费时间多的工作，最好开个线程来做。

[皆灾]

代码肯定是没有问题我觉得，因为我反复确认过。我是按照书上所说去选择了basic 或者选择empty都是会提示这个。 现在看到一百多页了，不管运行什么例子都提示这个。醉了，请问是安装环境有问题了么，还是我在创建项目的时候出现问题了

[皆灾]

还是搞不清楚为什么，不过幸好的是我刚刚运行了一个空项目，没有提示这个问题。。

[__椎名真白]

我当时自学的时候也是这个提示，一直logcat里面弹弹弹，百度结果就是不要在主线程做太多的耗时操作，耗时的交给子线程，避免主线程阻塞。不过你也不用管这个，完全没啥影响的，先学东西再说。
