Android 監控程序安裝和刪除的實現

通過閱讀Android SDK裏關於intent.action這部分裏面的描述，我們可以找到一些與package相關的系統廣播

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裏的描述是  

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

ACTION_PACKAGE_REMOVED

在SDK裏的描述是

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

ACTION_PACKAGE_REPLACED

在SDK裏的描述是

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

通過這三個廣播消息 我們已經可以監控到Android 應用程序的安裝和刪除

詳細的實現代碼如下:

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, "有應用被添加", Toast.LENGTH_LONG).show();
            }
                else  if(Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())){
                    Toast.makeText(context, "有應用被刪除", Toast.LENGTH_LONG).show();
            }
             /*   else  if(Intent.ACTION_PACKAGE_CHANGED.equals(intent.getAction())){
                    Toast.makeText(context, "有應用被改變", Toast.LENGTH_LONG).show();
            }*/
                else  if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())){
                    Toast.makeText(context, "有應用被替換", Toast.LENGTH_LONG).show();
            }
               /* else  if(Intent.ACTION_PACKAGE_RESTARTED.equals(intent.getAction())){
                    Toast.makeText(context, "有應用被重啓", Toast.LENGTH_LONG).show();
            }*/
              /*  else  if(Intent.ACTION_PACKAGE_INSTALL.equals(intent.getAction())){
                    Toast.makeText(context, "有應用被安裝", Toast.LENGTH_LONG).show();
            }*/

        }

}

然後在AndroidManifest.xml中聲明這幾個Action的<intent-filter>即可在系統裏捕獲這些廣播消息

具體的源代碼如下

<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()可以得到安裝的是哪個apk，如：

      package:com.android.myapp
