the application can't be displayed on the emulator

Hi guys,

I'm starting with android and writing my first helloworld program, I found a problem. The emulator does not show nothing. I was reading the other posts but there wasn't anything to help out. I was thinking that maybe there was something wrong with the installation, so I did again but the problem remains.

So this is the messages that appear on the console:

[2010-07-27 20:42:20 - HelloAndroid2] HOME is up on device 'emulator-5554'
[2010-07-27 20:42:20 - HelloAndroid2] Uploading HelloAndroid2.apk onto device 'emulator-5554'
[2010-07-27 20:42:20 - HelloAndroid2] Installing HelloAndroid2.apk...
[2010-07-27 20:43:34 - HelloAndroid2] Success!
[2010-07-27 20:43:34 - HelloAndroid2] Starting activity com.example.hello2.HelloWorld on device
[2010-07-27 20:43:46 - HelloAndroid2] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.hello2/.HelloWorld }

Thanks,

jack

The emulator does not show nothing

Means it does show something! :-p

The console messages are normal and your activity has started.

I assume your application looks something like
Code: Select all

class HelloWorld extends Activity {

@override
public onCreate(Bundle b){
    setContentView(R.layout.main);
}
}


If it does, basically your activity is starting and then setting it's contents to be "main".

If you look in your res folder (resources) (R) then in the layout directory (layout) then find a file called main.xml (main) (R.layout.main).

This is what your view is getting set to, now more than likely this is either blank or is just setting a TextView to a string in Strings.xml res/values/strings.xml so either Main.xml is empty or Strings.xml is empty

Go have a play :-)
