我知道我必須使用BOOT_COMPLETED和廣播接收器。但我只需要一個樣本來從Broadcast receiver註冊Geofence。我創建了一個Geofence服務calss，並嘗試從BroadcastReceiver啓動它，但它不起作用。如何在手機重新啓動時註冊地理圍欄？
public class BootCompleteReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
//Or whatever action your receiver accepts
if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
Toast.makeText(context , "APP REBBOT RECEIVED" , Toast.LENGTH_LONG).show();
Intent serviceIntent = new Intent(context , GeoFenceObserversationService.class);
context.startService(serviceIntent);
// GeoFenceObserversationService.getInstant().addGeofences();
}
}}

但我沒有在其他地方添加Geofence。我的服務課程也不盡如人意。 mGoogleApiClient始終爲空且未連接。 addGeofence就是一種方法。 –
那麼，你需要讓你的'服務'工作。你的問題意味着你在重啓時遇到問題。你應該讓你的'服務'先工作，然後解決重啓問題（如果它仍然存在）。 –
你能告訴我我在哪裏犯錯。我是一個新手。我希望你的回答會幫助我 –
