    I built đťobile temple (Android package or package Android ETC1). When run the application on my mobile device, there is a black screen, and then crashes. I looked through the logs (Log cats), so you can see UE4.1 can't find a lot of files. What could be the problem? Settings UI4.1:
    Mobile NO HDR
    Culling NO
    Texture Streaming NO
    Use DXT5 Normal Maps NO
    Allow Static Lighting YES
    Separate Traslucency NO
    Movables in early Z-pass NO.
    Mobiler: CPU - MediaTek MT6572; video - Mali-400

      @Oleg,
      I seem to have read somewhere that you need to something else apart from copying the apk, copying an extra file somewhere if I am not mistaken. I will try to look it up later. I am a UE4 newbie too!

      Been testing more with building for Android. Unfortunately, at least on my device, anything transparent crashes the mobile test Will try to pinpoint exactly what is wrong. The background clouds work, so it must be the way I am building my material?

        I do the Assembly and get a *.bat file that installs apk on the phone. I think the *.bat file must install all the files on my device. Or am I wrong?

          Thanks for al the information you provided. At first when i compiled Tappy Chicken (without modifications) with ETC1 compression and pushed it to my Huawei Honor 2 (U9508 2GB) it starts the apk but gives me a black empty screen and almost freezes my phone. I don't really know what kind of texture compression i should sellect since i can't really find out what type of gpu my phone has other than that its a HiSilicon. When i get back at my development pc i shall look further into those links you provided.

              Thanks everyone for your posts! ... Hopefully together we can all work out how to get this working better.

              I see today Epic have released their roadmap which also allows us to vote on the most useful features we would like to have.

              Of really great interest is the suggestion they are asking us all to vote on, is if we would like to have "Mobile preview in editor"! ... that would help a great deal as we could get on with more development, (especially now), while we wait for better overall support of older phones. ... It is these build times I'm seeing here, that I was posting about, that is a big problem for actual devices currently, but if we can use our PC's as another target device effectively, for mobile development, then that would greatly help us, until they have more time to better support these older phones.

              Here's the link if you would like to vote on it!

                I got it working on my Galaxy S1 (running android 4.4.2 helps im sure) It runs tappy bird at about 30 fps! which isnt bad

                Here is a post about me trying my game and working on UE 4.2 From source (+ some extra commits that haven't been merged)
                https://twitter.com/TheKRushin/statu...17732092846080

                Its phenominal... I'm actually shocked and happy it work. It seems like the only thing that UE kinda struggles at is all the older version of android/ all the variation (that aren't AOSP based)
