android中通过反射实现强制停止应用程序

来源：互联网发布：数据伞监控软件编辑：程序博客网时间：2024/05/19 23:26

private ActivityManager manager;private List<RunningAppProcessInfo> runningProcesses;private String packName;private PackageManager pManager;@Overridepublic void onReceive(Context context, Intent intent) {pManager = context.getPackageManager();manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);killOthers(context);}/** * 杀死其他正在运行的程序 *  * @param context */private void killOthers(Context context) {runningProcesses = manager.getRunningAppProcesses();for (RunningAppProcessInfo runningProcess : runningProcesses) {try {packName = runningProcess.processName;ApplicationInfo applicationInfo = pManager.getPackageInfo(packName, 0).applicationInfo;if (!"com.asms".equals(packName)&&filterApp(applicationInfo)) {forceStopPackage(packName,context);System.out.println(packName+"JJJJJJ");}}catch(Exception e){e.printStackTrace();}}}/** *强制停止应用程序 * @param pkgName */private void forceStopPackage(String pkgName,Context context) throws Exception{        ActivityManager am = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);Method method = Class.forName("android.app.ActivityManager").getMethod("forceStopPackage", String.class);method.invoke(am, pkgName);    }/** * 判断某个应用程序是 不是三方的应用程序 * @param info * @return  */    public boolean filterApp(ApplicationInfo info) {        if ((info.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {            return true;        } else if ((info.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {            return true;        }        return false;    }

说明：如果是在Activity中将onReceiver方法换成onCreate方法即可。

2.需要在AndroidManifest.xml 把package的userid设置为system

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.asms"    android:versionCode="1"    android:versionName="1.0" android:sharedUserId="android.uid.system">
