我有一个正在构建的应用程序,但是在返回 START_STICKY 行后遇到了一个错误,指出“无法访问代码”;从 if (Config.DEVELOPMENT) { 开始,我不确定如何解决这个问题,以便我的源代码正确执行。

源代码段:

} else if (extras.getString(Constants.DM_SMS_CONTENT).contains(
            "//USR;0")) {

        // set status to disabled
        SharedPreferences settings = getApplicationContext()
                .getSharedPreferences(Constants.PREFS_NAME, 0);
        Editor editor = settings.edit();
        editor.putString("status", "0");
        editor.commit();
        //stopSelf();

        return flags;

    }

    return START_STICKY;

    if (Config.DEVELOPMENT) {

        period = Constants.PERIOD;
        delay_interval = Constants.DELAY_INTERVAL;

    } else {

        period = Constants.DEBUG_PERIOD;
        delay_interval = Constants.DEBUG_DELAY_INTERVAL;
    }
    startServiceTimer();

}
return startId;

}

一旦您发表return声明;超出它的同一块中的所有代码都无法访问。

要么删除return语句之外的代码,要么将其移动到语句之前,return以便它可以访问。

为了消除多次返回的混淆,首先决定你想要返回什么,然后每个方法只有一个返回语句。

像这样的东西:

public void onStartCommand(){
   int statusId;
   if(...){
       //....
       statusId = someValue;
    }else if(...){
       //...
       statusId = otherValue;
    }else{
      statusId = defaultValue;
    }

    return statusId;
}
