I am creating turistic app and I have made some significant research about design. Now I want to try in Android display background image in main menu. Do you know, is it possible to have there image, which changes periodically with some transition effects? On background there should be turistic pictures, which will be changing time to time. Is it possible with Android? I am asking here, cos I wasn't able to find solution up to now.
Thanks
Did you tried to use this?
Why not! you can apply a thread which will change the background image from time to time, and if you are going to deploy it not ICS you can have the transition effect also.

I am making an app on android using kotlin and there's this tricky part where the admin has to load an image to the app , when that's done the background of the layout is set to that image , the image itself has these 4 or 5 red dots spread according to a blueprint. What I want to do is to detect where those dots are then put some components over them ( Button, TextView..). I know my question is a bit complex but i hope someone could help me because I don't even know where to start with this. Thank you.
I am interested in what the current best practice for android API 16 is when it comes to changing a notification button.
Currently I set the bigContentView and use setOnClickPendingIntent() to make callbacks to the service but I'm finding the notification to be really slow at being updated as it has to change one of the button images between two different states (like toggling play/pause).
After logging ive traced it down to the code of swapping the drawable button.
setImageViewResource(viewId, srcId);
Takes anywhere from 1.0s - 0.3s which is a noticable delay for the user, surely there must be a better way? Or something I'm blatantly missing?
Any suggestions to avoid the update delay or any feedback on my current implementation would be greatly appreciated.
Load the two ImageViews above each other and switch the visibility between them. This way you will only need to load them once and you will avoid many Garbage Collection calls that could result in slow responsiveness in your app and you can also scale down your resources to a smaller size.
Is it possible to create a fog effect on the screen of an android phone. iFoggy was able to get this effect (see picture) for an iPhone.
Is it possible to achieve the same for an android app. I just want the foggy effect and don't want anything to happen when the user touches the screen.
I'm guessing this might be achieved using Bitmap but I've never used that before so any tips would be helpful.
you can have a look at this question here to have Blur Effect for your screen
Make a transparent activity. Refer this answer. click
And set the background for the layout of this activity, a transparent PNG file. Here is the PNG file.

I have home screen widget that shows images. Images are switching for some scenario. I need to add fade effect on images switching. Is it some way to do it?
I know how to use animation for my purpose on View, but AppWidget uses RemoteViews...
There is no ordinary thing to do that. The only thing you can do - use bitmap alpha channel for fadding image, but it takes all processor time. My advice - do not do that.
I'm attempting to fade between two background images on my Droid, but the animation seems to get 5fps if not less. Is there any method I can use other than fading in\out a couple image views that would be smoother?
You can set your background to be defined by a TransitionDrawable. Used it to develop a nice splash screen that fades in and didn't have any issues.
I'm not exactly sure what you want to do, but if you want to change from one screen to the other within the same app you should use the ViewFlipper.
View Flipper on Android Developer site
This will allow to smoothly change from one screen to the other (much like the iPhone way).
If it is about the actual Android background i can't help you. Sorry.
