无法创建服务

Question

我是 android 的新手，正在我的一个提醒应用程序中创建服务。但是当我在我的 activity 的 onCreate() 方法中调用 startService() 时，我的服务被触发我无法看到在我的服务的不同方法中使用的 toasts class.As new to android 无法找出问题所在。 主要活动：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_activity_show_reminders);
        isReminders = false;
        dataSrc = new RemitDataSrc(this);
        dataSrc.open();

         rem = dataSrc.findALL();
        refreshDisplay();
    }
    private void refreshDisplay(){
        if(isMyServiceRunning(GeofencingService.class)){
            Intent intent = new Intent(this, GeofencingService.class);
            stopService(intent);
            Toast.makeText(this, "yes service", Toast.LENGTH_LONG).show();
        }else{
        Toast.makeText(this, "No service", Toast.LENGTH_LONG).show();
        }
        if(rem.size()==0){

            Toast.makeText(this, "No Reminders in Database", Toast.LENGTH_LONG).show();
        }


        Intent intent = new Intent(this, GeofencingService.class);
        startService(intent);
            ArrayAdapter<Reminders> remAdpt = new RemindersListAdapter(this, rem);
            setListAdapter(remAdpt);


    }
    private boolean isMyServiceRunning(Class<?> serviceClass) {
        ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
            if (serviceClass.getName().equals(service.service.getClassName())) {
                return true;
            }
        }
        return false;
    }

地理围栏服务：

public class GeofencingService extends Service{
    RemitDataSrc dataSrc;
    /**
     * Geofence Store
     */
    private GeofenceStore mGeofenceStore;
    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }
    @Override
    public void onCreate() {

        super.onCreate();
        Toast.makeText(this, "GeoFencing Service created", Toast.LENGTH_LONG).show();
        dataSrc = new RemitDataSrc(this);
        dataSrc.open();
    }
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Toast.makeText(this, "GeoFencing Service Started", Toast.LENGTH_LONG).show();
        serviceTest sT= new serviceTest();
        dataSrc.open();

        return super.onStartCommand(intent, flags, startId);
    }
    @Override
    public void onDestroy() {

        super.onDestroy();
        Toast.makeText(this, "GeoFencing Service Stoped", Toast.LENGTH_LONG).show();
        dataSrc.close();
    }

}

manifest.xml:

        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"

Answer 1

请将您的服务作为应用程序的子项注册到您的清单中，例如：

<application ..>
..
    <service
            android:name=".GeofencingService"
            android:enabled="true">
    </service>
</application>

Answer 2

在应用程序标签下的项目清单中提及该服务。像这样

<service android:name=".ServiceName" />

Answer 3

正如您在其中一条评论中提到的，服务的包名称与包含 activity 的包不同，请在清单中使用完全限定的 class 名称和包名称。

<service 
android:name="com.afifa.projectreminder.service.GeofencingService" android:exported="false" 
> 
</service>
