Android在应用中依据包名启动另外一个APP

以下为TestIntentData工程

MainActivity如下:

package cn.testintentdata;

import android.net.Uri;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.app.Activity;

import android.content.ComponentName;

import android.content.Intent;

import android.content.pm.PackageInfo;

import android.content.pm.PackageManager.NameNotFoundException;

import android.content.pm.ResolveInfo;

/**

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

			} else {

				System.out.println("packageInfo!=null");

			}

		} catch (NameNotFoundException e) {

			e.printStackTrace();

		}

		 

		

		//<data android:scheme="app" android:host="jp.co.cybird.barcodefootballer/" />
