Android 监控程序装配和删除的实现

通过阅读Android SDK里关于intent.action这部分里面的描述，我们可以找到一些与package相关的系统广播

android.intent.action.PACKAGE_ADDED???????
android.intent.action.PACKAGE_CHANGED???????
android.intent.action.PACKAGE_DATA_CLEARED???????
android.intent.action.PACKAGE_INSTALL?????
android.intent.action.PACKAGE_REMOVED?????
android.intent.action.PACKAGE_REPLACED???????
android.intent.action.PACKAGE_RESTARTED??

其中

ACTION_PACKAGE_ADDED

在SDK里的描述是 ?

Broadcast Action: A new application package has been installed on the device.

ACTION_PACKAGE_REMOVED

在SDK里的描述是

Broadcast Action: An existing application package has been removed from the device.

ACTION_PACKAGE_REPLACED

在SDK里的描述是

Broadcast Action: A new version of an application package has been installed, replacing an existing version that was previously installed.

通过这三个广播消息 我们已经可以监控到Android 应用程序的安装和删除

详细的实现代码如下:

package?zy.Broadcast;???
import?android.content.BroadcastReceiver;???
import?android.content.Context;???
import?android.content.Intent;???
import?android.widget.Toast;???
public?class?getBroadcast?extends?BroadcastReceiver?{???
????????@Override???
????????public?void?onReceive(Context?context,?Intent?intent)?{???
??????????????????
??????????????????if(Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())){???
????????????????????Toast.makeText(context,?"有应用被添加",?Toast.LENGTH_LONG).show();???
????????????}???
????????????????else??if(Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())){???
????????????????????Toast.makeText(context,?"有应用被删除",?Toast.LENGTH_LONG).show();???
????????????}???
?????????????/*???else??if(Intent.ACTION_PACKAGE_CHANGED.equals(intent.getAction())){??
????????????????????Toast.makeText(context,?"有应用被改变",?Toast.LENGTH_LONG).show();??
????????????}*/???
????????????????else??if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())){???
????????????????????Toast.makeText(context,?"有应用被替换",?Toast.LENGTH_LONG).show();???
????????????}???
???????????????/*?else??if(Intent.ACTION_PACKAGE_RESTARTED.equals(intent.getAction())){??
????????????????????Toast.makeText(context,?"有应用被重启",?Toast.LENGTH_LONG).show();??
????????????}*/???
??????????????/*??else??if(Intent.ACTION_PACKAGE_INSTALL.equals(intent.getAction())){??
????????????????????Toast.makeText(context,?"有应用被安装",?Toast.LENGTH_LONG).show();??
????????????}*/???
???????????????
????????}???
??????????
}???

然后在AndroidManifest.xml中声明这几个Action的<intent-filter>即可在系统里捕获这些广播消息

具体的源代码如下

<receiver?android:name="getBroadcast"?android:enabled="true"?>???
?????????<intent-filter>???
?????????????<action?android:name="android.intent.action.PACKAGE_ADDED"></action>???
?????????????<!--?<action?android:name="android.intent.action.PACKAGE_CHANGED"></action>-->???
?????????????<action?android:name="android.intent.action.PACKAGE_REMOVED"></action>???
?????????????<action?android:name="android.intent.action.PACKAGE_REPLACED"></action>???
?????????????<!--?<action?android:name="android.intent.action.PACKAGE_RESTARTED"></action>-->???
???????????<!--????<action?android:name="android.intent.action.PACKAGE_INSTALL"></action>-->???
???????????????<data?android:scheme="package"></data>???
??????????????</intent-filter>???
</receiver>??

另： intent.getDataString()可以得到安装的是哪个apk，如：

????? package:com.android.myapp
