I just finished reproducing and confirming the following issue:
UE 4.5.1 + Top-Down Blueprint Deploys and runs fine on mid-range Android Galaxy S4 Mini with following changes:
- Start the project with Mobile-scalability and Starter Content
- Change all materials to “Unlit” and “Fully rough”
- Copy from UE 4.5.1 engine distribution the Android-binaries (namely just 1-2 files) under Engine/Binaries/Android - as the deployment suggests to
- Deploy from editor
Game starts without issues.
Trying to repeat the above with 4.6.x or 4.7.x fails without any clear error message; the game deploys without errors, but the device simply closes the app (either silently or with blunt “has stopped” messagebox). I know there has been changes around manifest files, but there are no obvious permission issues on the logs that would give out the reason for silent-crash failure.
For more background info, the S4 Mini runs with Adreno 305; while it’s not high-end GPU, it’s also found for some other low-mid-range Samsung models such as Galaxy Express 2. These are great devices to be able to run UE4, because they reach much-much wider market than the expected flagship devices. The S4 Mini is also listed in Android Device Compatibility.
I hope someone can help solve the issue; there is no lag on the 4.5.1 example games, so it doesn’t look like it’s on the “barely functional” edge either…
