第一、 新建監聽類:BootReceiver繼承BroadcastReceiver
public class BootReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
//接收廣播:系統啓動完成後運行程序
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:設備上新安裝了一個應用程序包後自動啓動新安裝應用程序。
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:設備上刪除了一個應用程序包。
if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {
System.out.println("********************************");
DatabaseHelper dbhelper = new DatabaseHelper();
dbhelper.executeSql("delete from users");
}
}
第二、 修改AndroidManifest.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.me.watchinstall">
<application>
<receiver android:name=".BootReceiver"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED" />
<action android: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>
<activity android:name=".WatchInstall" android:label="WatchInstall">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RESTART_PACKAGES"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
</manifest>
