如何从包名获得PID？ [英] How to get PID from package name?

问题描述

我需要创建一个函数，但我不知道如何让应用程序的PID。

  //这里返回-1，但我需要PID杀掉进程
整数的PID1 = android.os.Process.getUidForName（com.android.email）;android.os.Process.killProcess（PID1）;
 

解决方案

尝试

restartPackage code

  ActivityManager AM =（ActivityManager）;
。getApplicationContext（）getSystemService（getApplicationContext（）ACTIVITY_SERVICE）;
aM.restartPackage（com.android.email）;
 

终止后台进程code

  ActivityManager AM =（ActivityManager）
getApplicationContext().getSystemService(Catalogue.content_holder.getApplicationContext().ACTIVITY_SERVICE);
aM.killBackgroundProcesses（com.android.email）;
 

下面是code这获取所有正在运行的应用程序，并请检查是否电子邮件应用程序已经运行与否，如果它正在运行然后杀死该进程

  ActivityManager经理=（ActivityManager）getApplicationContext.getSystemService（getApplicationContext.ACTIVITY_SERVICE）;
清单＆LT; RunningAppProcessInfo＆GT; activityes =（（ActivityManager）经理）.getRunningAppProcesses（）;对（INT ICNT = 0; ICNT＆下; activityes.size（）; ICNT ++）{    的System.out.println（APP：+ ICNT ++ activityes.get（ICNT）.processName）;    如果（activityes.get（ICNT）.processName.contains（com.android.email））{
        android.os.Process.sendSignal（activityes.get（ICNT）.pid，android.os.Process.SIGNAL_KILL）;
        android.os.Process.killProcess（activityes.get㈠.pid）;
        //manager.kil​​lBackgroundProcesses(\"com.android.email）;        //manager.restartPackage(\"com.android.email）;        的System.out.println（内部如果）;
    }}
 

I need create a function but I don't know how to get the PID of the app.

// here return -1 but I need PID to kill process
Integer PID1= android.os.Process.getUidForName("com.android.email");

android.os.Process.killProcess(PID1);

解决方案

try

restartPackage code

ActivityManager aM = (ActivityManager);
getApplicationContext().getSystemService(getApplicationContext().ACTIVITY_SERVICE);
aM.restartPackage("com.android.email");

Kill BackGround Process Code

ActivityManager aM = (ActivityManager)
getApplicationContext().getSystemService(Catalogue.content_holder.getApplicationContext().ACTIVITY_SERVICE);
aM.killBackgroundProcesses("com.android.email");

Here is code which fetches all running Application and check wether email app is already running or not , if it is running then kill that process

ActivityManager manager =  (ActivityManager) getApplicationContext.getSystemService(getApplicationContext.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> activityes = ((ActivityManager)manager).getRunningAppProcesses();

for (int iCnt = 0; iCnt < activityes.size(); iCnt++){

    System.out.println("APP: "+iCnt +" "+ activityes.get(iCnt).processName);

    if (activityes.get(iCnt).processName.contains("com.android.email")){
        android.os.Process.sendSignal(activityes.get(iCnt).pid, android.os.Process.SIGNAL_KILL);
        android.os.Process.killProcess(activityes.get(i).pid);
        //manager.killBackgroundProcesses("com.android.email");

        //manager.restartPackage("com.android.email");

        System.out.println("Inside if");
    }

}
