在模拟器上启动Android应用程序？

Question

I am new to developing Android Application and developing a HelloWorld app.

@Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        TextView text = new TextView(this);
        text.setText("Hello World");
        setContentView(text);

    }

But when I run my app on AVD, Following comes in my Console.

[2013-04-07 17:01:31 - Myapp] R.java was modified manually! Reverting to generated version!
[2013-04-07 17:01:48 - Myapp] ------------------------------
[2013-04-07 17:01:48 - Myapp] Android Launch!
[2013-04-07 17:01:48 - Myapp] adb is running normally.
[2013-04-07 17:01:50 - Myapp] Performing com.example.myapp.MainActivity activity launch
[2013-04-07 17:01:53 - Myapp] Automatic Target Mode: using existing emulator 'emulator-5554' running compatible AVD 'dv'
[2013-04-07 17:01:53 - Myapp] Uploading Myapp.apk onto device 'emulator-5554'
[2013-04-07 17:01:54 - Myapp] Installing Myapp.apk...
[2013-04-07 17:02:05 - Myapp] Success!
[2013-04-07 17:02:05 - Myapp] Starting activity com.example.myapp.MainActivity on device emulator-5554

Emulator also starts. But it does not print HelloWorld.

How i can make my app run?

Answer 1

Give the emulator some time (about 10 minutes). It takes him a very long time to boot up. If you wait long en ought then the android logo will disappear and you will receive the home screen.

You can take a look at this blog post I wrote on how to speed-up the emulator:

Speed UP the Emulator

Answer 2

The android emulator can take a while to load up. Sometimes it can take three or four minutes before I see the android home screen
