Android的 - 不能設置在服務類中的變量

Question

我有一個名爲ForegroundService服務類onstartCommand，我需要設置一個變量：

@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類開始：

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

有一種方法來設置該變量？

你的代碼是正確的，但除非你啓動此服務這樣的方法onStartCommand()將不會被調用：

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