2.程序A：

	        ComponentName componetName = new ComponentName(
	                 //package
	                "pers.phoenix.factory",
	                //activity 
	                "pers.phoenix.factory.AccountActivity"); 
	        Intent intent= new Intent();
	        Bundle bundle = new Bundle();
	        bundle.putString("action", "test");
	        intent.putExtras(bundle);
	        intent.setComponent(componetName);
	        startActivity(intent);

3.程序B的AndroidManifest.xml：

            android:name="pers.phoenix.factory.AccountActivity"
            android:theme="@android:style/Theme.NoDisplay" >

                <action android:name="android.intent.action.VIEW" />
            </intent-filter>
        </activity>

4.程序B的代码：

public class AccountActivity extends Activity{
	private static final String TAG = AccountActivity.class.getSimpleName();
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		
		Intent intent= getIntent();
        String value=intent.getStringExtra("action");
        Log.i(TAG, "parameter--------> " + value);   //余下省略......
