Hi all, just started looking into android app development, and am having troubles getting the apps i create to either display on the emulator or a real device. Even a very simple app like helloworld, installs on the device but it doesnt appear in the programs menu nor does it auto launch.

[2009-07-02 08:59:47 - hello15] Installing hello15.apk...
[2009-07-02 08:59:51 - hello15] Success!
[2009-07-02 08:59:51 - hello15] \hello15\bin\hello15.apk installed on device
[2009-07-02 08:59:51 - hello15] Done!

Any ideas please?

Anyone any ideas?

Do I need to launch the app manually on the device once its installed? Any ideas how to do that if so?

Below is the code.

PHP Code:


			
package com.android.helloandroid;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloAndroid 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("Hello, Android");
       setContentView(tv);
   }
}

After the "installed on device", the app should launch automagically.

I'd say, try to re-install the Android plugin; you should be able to do that without zapping your workspace. Then, also create a new virtual device.

Hey, I had the same problem.

When you are developing in Eclispe, try to make a new project and let the Wizard make a new Activity.

I first had said "Nor Activity" and I could not start the App, but for me it worked with making a new Project and saying Create Activity. (There is a checkbox in the Wizard to do that)
