获取有关所有正在运行的进程的信息

问题描述：

我有一个想法，可以为Android制作任务管理器.有人可以告诉我如何在Android中当前运行的所有进程吗?

I have an idea to make Task Manager for android.Can anyone tell me how to get all the processes currently running in android?

答

使用下面的代码，您可以获取正在运行的进程的列表:-

using the code below you can get the list of running processes:-

ActivityManager actvityManager = (ActivityManager)
this.getSystemService( ACTIVITY_SERVICE );
List<RunningAppProcessInfo> procInfos = actvityManager.getRunningAppProcesses();

for(RunningAppProcessInfo runningProInfo:procInfos){

        Log.d("Running Processes", "()()"+runningProInfo.processName);
}

要获取基于包名称的应用程序名称，请使用 PackageManager 类.

final PackageManager pkgmgr = getApplicationContext().getPackageManager();
ApplicationInfo appinfo;
try {
    appinfo = pkgmgr.getApplicationInfo( this.getPackageName(), 0);
} catch (final NameNotFoundException e) {
    appinfo = null;
}
final String applicationName = (String) (appinfo != null ? pkgmgr.getApplicationLabel(appinfo) : "(unknown)");

要使用PID获取应用名称，请使用:-

public static String getAppNameByPID(Context context, int pid){
    ActivityManager manager 
               = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);

    for(RunningAppProcessInfo processInfo : manager.getRunningAppProcesses()){
        if(processInfo.pid == pid){
            return processInfo.processName;
        }
    }
    return "";
}

最后检查应用是否为系统应用:-

and finally to check if an app is system app or not use:-

private boolean isSystemPackage(PackageInfo pkgInfo) {
        return (pkgInfo.applicationInfo.flags & 
                ApplicationInfo.FLAG_SYSTEM) != 0;
    }
