My first Android app attempt

[clayshannon]

I'm trying to run a very simple (my first) Android app in an emulator I've set up, but my app doesn't display within the emulator. I'm expecting to see (code below) a TextView with some Text assigned to it.

All I see is a black "honeycomb" background in the emulator (which looks like a "DOS box" or Command prompt) with the time (5 hours in the future), date, and "Charging (50%)"

I'm using an AVD set up to use a version 3.2 emulator. I've got that (Andorid 3.2 SDK) and Java 7 installed.

Here is what is contained in my Eclipse tabs:

Console:

Code:

import android.app.Activity;

public class YeauxDudimusActivity extends Activity {
    /** Called when the activity is first created. */   
@Override    
public void onCreate(Bundle savedInstanceState) {        
  super.onCreate(savedInstanceState);        
  TextView tv = new TextView(this);        
  tv.setText("Yeaux, Dudimus");        
  setContentView(tv);        
  setContentView(R.layout.main);            
  }
}

Have you tried launching the emulator separately first using Android SDK and AVD Manager? Also, can you create a new Android project and have it run on the emulator?

I don't see anything in your code that would cause a problem, however there is a bug that will give you unexpected results:

@Override    
public void onCreate(Bundle savedInstanceState) {        
  super.onCreate(savedInstanceState);        
  TextView tv = new TextView(this);        
  tv.setText("Yeaux, Dudimus");        
  setContentView(tv);        
  setContentView(R.layout.main);            
  }

You are calling setContentView twice. You either need to remove:

setContentView(R.layout.main);

or add the TextView to your main.xml layout file.
