監聽應用程式安裝和卸載

第一、             建立監聽類：BootReceiver繼承BroadcastReceiver

publicclass BootReceiver extends BroadcastReceiver {

 

    @Override

    public void onReceive(Context context,Intent intent) {

        //接收廣播：系統啟動完成後運行程式

        if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {

             Intent newIntent = new Intent(context,WatchInstall.class);

newIntent.setAction("android.intent.action.MAIN");             newIntent.addCategory("android.intent.category.LAUNCHER");           newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            context.startActivity(newIntent);

        }

        //接收廣播：裝置上新安裝了一個應用程式套件組合後自動啟動新安裝應用程式。

        if(intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {

            String packageName =intent.getDataString().substring(8);

           System.out.println("---------------" + packageName);

            Intent newIntent = new Intent();

          newIntent.setClassName(packageName,packageName+ .MainActivity");

newIntent.setAction("android.intent.action.MAIN");            newIntent.addCategory("android.intent.category.LAUNCHER");             newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

            context.startActivity(newIntent);

        }

        //接收廣播：裝置上刪除了一個應用程式套件組合。

        if(intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")){

           System.out.println("********************************");

        }

    }

第二、             修改AndroidManifest.xml設定檔

<?xmlversion="1.0" encoding="UTF-8"?>

<manifestxmlns:android="http://schemas.android.com/apk/res/android"

     package="org.me.watchinstall">

    <application>

        <receiverandroid:name=".BootReceiver"

                 android:label="@string/app_name">

            <intent-filter>

                <actionandroid:name="android.intent.action.BOOT_COMPLETED"/>

                <categoryandroid:name="android.intent.category.LAUNCHER" />

            </intent-filter>

            <intent-filter>

             <actionandroid:name="android.intent.action.PACKAGE_ADDED" />

             <actionandroid:name="android.intent.action.PACKAGE_REMOVED" />

              <data android:scheme="package" />

<!-- 注意！！這句必須要加，否則接收不到BroadCast -->

           </intent-filter>

        </receiver>

        <activityandroid:name=".WatchInstall"android:label="WatchInstall">

            <intent-filter>

                <actionandroid:name="android.intent.action.MAIN"/>

                <categoryandroid:name="android.intent.category.LAUNCHER"/>

            </intent-filter>

        </activity>

    </application>

</manifest>
