How To Make Background Process in Android Studio

 

[액티비티]

public class App extends Application {

    private static App instance;
    private static Context context;

    @Override
    public void onCreate() {
        super.onCreate();

        App.context = getApplicationContext();

        startService(new Intent(this, YourBackgroundService.class));
    }
}

 

[클래스]

public class YourBackgroundService extends Service {

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        return super.onStartCommand(intent, flags, startId);
    }
}

 

[AndroidManifest.xml]

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

 

 

 

 

참고 2) 

public class YourBackgroundService extends Service {

 @Override
    public IBinder onBind(Intent intent) {
        throw new UnsupportedOperationException("Not yet implemented");
    }
 
    @Override
    public void onCreate() {
        super.onCreate();
        ServerThread thread = new ServerThread();
        thread.start();
    }
 
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }
 
    @Override
    public void onDestroy() {
        super.onDestroy();
    }
    
    
    class ServerThread extends Thread {
    ...
    }

    
}

 

구현하고자 하는 백그라운드 기능들은 onCreate 클래스에 적어주면 된다. 

※ 단 Toast 문자 같은 View에 변화가 생기는 기능은 오류가 생긴다.
