I've recently released a BT 3.0 app in Google Play, but I have since found it doesn't load on two peoples Galaxy devices. They work fine on my tablet and my simulators. The same app compiled into BT 2.0 seems to be OK. I can't figure it out! I've seen a couple of other people post on similar issues, but I've not seen any resolutions. I am considering 'upgrading' the released app to BT 2.0, but before I do, I'd like to know if I can make the BT 3.0 version work. Any and all suggestions welcome please.

They have had problems with flashing when you scroll....I.e the white screen turns black while scrolling. This is a problem for S2 and s3 devices. I resolved it by tweaking the background color and row background colors. Comments I have 3.0 apps working well on S2 ans S3 devices.

The issue is that I don't know why this app doesn't work on the galaxy devices, I cannot reproduce the problem, which bothers me. It suggests there must be something in my app that has pushed a BT 3.0 boundary. New base + my features worked on my devices. Old base + my features = improved compatibility. Currently feels like the way to go unless I can discover the problem. Alan Comments Thanks Susan.

Just drag all the images into all of the folders. The crashes I have seen most often are when a higher resolution device tries to upscale an image because it can't find the image in the hdpi or xhdpi folder. I sometimes resize the images that are used the most often, because that is the high road on how to use the drawable folders.

I put all images in all res drawable folders, but the app bulked out too much. I ended up just putting background images used in plugins in the different res drawables and I believe it made a difference. I managed to test my BT 3.0 version on various devices - all the non-Samsung devices were OK. On all the Samsung devices I tried (Galaxy S3, Note 3, S2 and S5) the app crashed when loading, it didn't get to the start screen. I just updated my app in google play but the only way I could get it to run on a Samsung was to go with BT 2.0, I still don't understand why BT 3.0+Samsung+my app is a no-no.
