[Interest] Preventing sleep on mobile platforms

[Nuno Santos]

You need to override the app delegate and activities on both iOS and Android and then the following does the trick

iOS:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [[UIApplication sharedApplication] setIdleTimerDisabled:YES];

    return YES;
}

Android:

public class YourActivity extends QtActivity
{

...

@Override
protected void onStart()
{
    super.onStart();

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
}
