Android - 无法在Service类中设置变量

Question

我有一个名为ForegroundService的服务类，在onstartCommand中我需要设置一个变量：

@Override
   public int onStartCommand(Intent intent, int flags, int startId) {
     VariableManaging.isStop=false; //<==variable i need to set. Here i got an exceptioninInitializer error when my bootReceiver start service on startup. If service is start by button on activity got no error. 
   }

VariableManaging类以：

开头

static boolean isStop=true;
static ProgressDialog progressDialog=new ProgressDialog(Main.activity); //<== I noted that if i remove this all working well

有一种设置变量的方法吗？

您的代码是正确的，但除非您像这样启动此服务，否则不会调用方法onStartCommand()：

startService(new Intent(getApplicationContext(), ForegroundService.class));
