在Eclipse上运行Android程序时出现问题

Question

I downloaded complete Android Environment Development Environment Snapshots from marakana.com . I start eclipse and create new Android project. On the Run Configurations , i created New Configuration to run the application, and set the Target to Automatic and select the AVD that appropriate to run the application. But, when i click on the run icon, it starts the new emulator, and after some minutes, just android emulator be ran and my application doesn't run on it.

What do i do to solve the running problem and run my project on emulator ?

NOTE 1 : Console outputs :

[2012-03-07 16:03:49 - New] ------------------------------
[2012-03-07 16:03:49 - New] Android Launch!

NOTE 2 : My Program Source:

package com.android.example;

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

public class NewActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

Thanks for your attention :)

Answer 1

To start an Activity it needs an intent-filter like this:

<activity android:name=".NewActivity">
  <intent-filter>
    <action android:name="android.intent.action.MAIN"/>
    <category android:name="android.intent.category.LAUNCHER"/>
  </intent-filter>
</activity>

Depending on your package name you can start it from the command line like this:

adb shell am start -n your.package.name/.NewActivity
