public class MainActivity extends Activity{

	@Override
	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		Log.e("nafio","start load1");

		ComponentName componetName = new ComponentName(
				//这个是另外一个应用程序的包名
				"com.example.t2",
				//这个参数是要启动的Activity
				"com.a.cc.TActivity");

		try {
			
			Intent intent = new Intent();
			
			intent.setComponent(componetName);
			
			startActivity(intent);
			
		} catch (Exception e) {
			
			Toast.makeText(getApplicationContext(), "可以在这里提示用户没有找到应用程序，或者是做其他的操作！", 0).show();

			Log.e("nafio",e.getMessage());
		}

		Log.e("nafio","end load");
	}

}

被启动的工程，包名为com.example.t2 ,因为TActivity为非Action.Main,要想外部访问，要加android:exported="true"

package com.example.t2;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;


public class MainActivity extends Activity{

	@Override
	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		Log.e("nafio","T2---------------");

		

	}

}

package com.a.cc;

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

public class TActivity  extends Activity{

	@Override
	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		Log.e("nafio","TActivity!!!!!---------------");

		

	}

}

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.t2"
    android:versionCode="1"
    android:versionName="1.0" >
