Android 监控程序安装和删除的实现

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
