Such kind of issues occures usually, if lots of operations are performed inside OnAppInitializing().keep the number of operations minimal as as possible inside OnAppInitializing() and restrict it to initialization operations only.

This is my OnAppInitializing. I think I cannot remove nothing more. Maybe the reason is that I am using a Form. bool Game::OnAppInitializing(AppRegistry& appRegistry) { //////////////////////////////////////////////////////////////////////////////////// //this codes is automatically inserted by Tizen Application Wizard. Tizen::Ui::Controls::Frame* pAppMainFrame = new Tizen::Ui::Controls::Frame(); pAppMainFrame->Construct(); pAppMainFrame->SetName(L"MainFrame"); danegry.rozmiar_x = pAppMainFrame->GetHeight(); danegry.rozmiar_y = pAppMainFrame->GetWidth(); AddFrame(*pAppMainFrame); //////////////////////////////////////////////////////////////////////////////////// Form1 *pForm1 = new Form1(); pForm1->Construct(FORM_STYLE_NORMAL); pForm1->SetOrientation(ORIENTATION_LANDSCAPE); pForm1->InitTimer(); pAppMainFrame->AddControl(*pForm1); pAppMainFrame->SetCurrentForm(*pForm1); result r; AppRegistry* pAppRegistry = GetAppRegistry(); String key; key.Clear(); key.Append(L"rekord "); r = pAppRegistry->Get(key, rek.rek); if ( r == E_KEY_NOT_FOUND) {AppLog("NOT FOUND");pAppRegistry->Add(key, rek.rek);} r = pAppRegistry->Save(); if( IsFailed(r)) { AppLog("NOT SAVED"); } datagame.iniciated = false; return true; }

It works fine for me. Does your application's class inherit Tizen::App::UiApp? You may try starting from a new Tizen template and just filling all the code in there - that way you'll avoid some incompatible old bada things. You could also just have almost no code in OnAppInitializing and move it to OnAppInitialized, though I doubt it will solve your problem.

We must use the class, which executes in a different thread, to provide a positive user experience in our application.

By keeping the number of operations performed within OnAppInitializing() to a minimum, the app can start up more quickly and with fewer performance issues. Initialization operations that might be performed within OnAppInitializing() could include setting up any necessary data structures, connecting to databases, or initializing configuration settings. 

In Tizen, when an application is sent to the background or is no longer visible on the screen due to a Home key press or device lock, the OnPause() method is called instead of OnBackground(). OnPause() is where you should pause your game or release any resources that are not needed while the application is not visible.

 

You should also make sure that your application is properly handling the AppControl::ACTION_PAUSE and AppControl::ACTION_RESUME events, as these will be sent when the application is paused or resumed. You can handle these events in the OnAppControlReceived() method of your Tizen::App::UiApp-derived class.

The behavior you are experiencing could be due to differences in the way that backgrounding and foregrounding are handled in Tizen compared to Bada. In Tizen, an app is typically suspended when it enters the background, which means that the app's execution is paused until it is brought back to the foreground.

To pause your game when the user presses the Home key or locks the device, you can listen for the "pause" event using the Tizen application lifecycle events API. Here is an example of how you can use this API to pause your game when the app enters the background:

You can place this code in your app's initialization function (OnAppInitializing) to register the pause listener. When the app enters the background, the registered function will be called and you can pause your game logic.

Similarly, you can use the tizen.application.setAppResumedListener() method to register a listener that will be called when the app is brought back to the foreground. You can use this listener to resume your game logic.

You can place this code in your app's initialization function (OnAppInitializing) along with the setAppPausedListener() call to register both listeners.

Note that the above code assumes that you have access to the Tizen Web API within your app. If you are using a different framework or platform, the approach may be different.

To implement background behavior in your application, you need to ensure that you follow the guidelines and APIs provided by the mobile operating system you are developing for.

I also have the same issue

It is not being called as expected, it can be frustrating and lead to unintended consequences. This problem could be attributed to various factors, such as incorrect implementation of the callback, framework limitations, or even device-specific issues.

You could also have almost no code in OnAppInitializing and move it to OnAppInitialized, but I doubt that will solve your problem.

 

I have the same problem

It might help to verify if the app is correctly handling transitions when going into the background. If anyone has found a reliable workaround. I’d love to hear your approach! Victoria's Drywall Taping Services
