android 判断是否卸载 android判断进程是否存在

1、权限：

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

2、代码：

public static boolean isServicesExisted(Context context, String serName) {
 
ActivityManager ac = (ActivityManager) context 

.getSystemService(Context.ACTIVITY_SERVICE); 

List<ActivityManager.RunningServiceInfo> serviceList = ac.getRunningServices(Integer.MAX_VALUE); 

for (int i = 0; i < serviceList.size(); i++) { 

RunningServiceInfo serviceInfo = serviceList.get(i); 

ComponentName serviceName = serviceInfo.service; 

if (serviceName.getClassName().equals(serName)) { 

return true; 

} 

} 

return false; 

} 

 

public static boolean isRunningTaskExist(Context context,String processName){ 

ActivityManager am=(ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); 

List<RunningAppProcessInfo> processList = am.getRunningAppProcesses(); 

for(RunningAppProcessInfo info:processList){ 

if (info.processName.equals(processName)){ 

                   return true; 

} 

} 

return false; 

}
