android - 如何在android中使用其包名杀死任何应用程序

Question

我正在尝试使用这样的包名称来终止正在运行的应用程序:

String nameofProcess=your-package-name;
    ActivityManager manager=(ActivityManager)MainActivity.this.getSystemService(Context.ACTIVITY_SERVICE);
    List<ActivityManager.RunningAppProcessInfo> listOfProcess=manager.getRunningAppProcesses();
    for(ActivityManager.RunningAppProcessInfo process:listOfProcess)
    {
        if(process.processName.contains(nameofProcess))
        {
            Log.e("Proccess" , process.processName + " : " + process.pid);
            android.os.Process.killProcess(process.pid);
            android.os.Process.sendSignal(process.pid, android.os.Process.SIGNAL_KILL);
            manager.killBackgroundProcesses(process.processName);
            break;
        }
    }

但它并没有杀死应用程序。当我转到最近的任务时，它仍然存在。 有什么问题吗？

在您的 list 文件中添加以下权限:

<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />

下面的函数将使用其包名终止应用程序:

private void killAppBypackage(String packageTokill){

        List<ApplicationInfo> packages;
        PackageManager pm;
        pm = getPackageManager();
        //get a list of installed apps.
        packages = pm.getInstalledApplications(0);


        ActivityManager mActivityManager = (ActivityManager) MainActivity.this.getSystemService(Context.ACTIVITY_SERVICE);
        String myPackage = getApplicationContext().getPackageName();

        for (ApplicationInfo packageInfo : packages) {

            if((packageInfo.flags & ApplicationInfo.FLAG_SYSTEM)==1) {
                continue;
            }
            if(packageInfo.packageName.equals(myPackage)) {
                continue;
            }
            if(packageInfo.packageName.equals(packageTokill)) {
                mActivityManager.killBackgroundProcesses(packageInfo.packageName);    
            }

        }

    }  

下面的代码会杀死除当前应用程序和系统应用程序之外的所有正在运行的应用程序:

                List<ApplicationInfo> packages;
                PackageManager pm;
                pm = getPackageManager();
                //get a list of installed apps.
                packages = pm.getInstalledApplications(0);


                ActivityManager mActivityManager = (ActivityManager) MainActivity.this.getSystemService(Context.ACTIVITY_SERVICE);
                String myPackage = getApplicationContext().getPackageName();

                for (ApplicationInfo packageInfo : packages) {

                    if((packageInfo.flags & ApplicationInfo.FLAG_SYSTEM)==1) {
                        continue;
                    }
                    if(packageInfo.packageName.equals(myPackage)) {
                        continue;
                    }
                    mActivityManager.killBackgroundProcesses(packageInfo.packageName);
                }
