android 监听添加或者删除应用

监听监听，顾名思义就要有broadcast和receive了。

//监听到安装新应用后的处理..
BroadcastReceiver installedBr = new BroadcastReceiver() {

		@Override
		public void onReceive(Context context, Intent intent) {
//有新的应用安装，主要是"android.intent.action.PACKAGE_ADDED"			
if (intent.getAction()
					.equals("android.intent.action.PACKAGE_ADDED")) {

//这个判断条件是防止其他卸载时影响到本应用
				if (context.getApplicationInfo().processName
						.equals("你的进程的名称")) {
				do the things that you wanted
				}
			}
		}
	};

注册监听，

		IntentFilter intentFilter1 = new IntentFilter(
				"android.intent.action.PACKAGE_ADDED");
		intentFilter1.addDataScheme("package");

		this.registerReceiver(installedBr, intentFilter1);

卸载程序也一样

android.intent.action.PACKAGE_REMOVED这个action
