Issues launching Unreal 5.2 app on headset
Hey folks ... looking for any insight here ... we are moving from 4.27 to 5.2 ... everything builds and packages fine through editor ... installing the app and everything shows up correctly under unknown sources, but running the app just gives the infinite three dots.
SDK and NDK are android-32, and we can launch and run successfully via the project launcher in Editor.
Running adb logcat it looks like the system can't actually find the obb when it tries to execute, and goes into a download wait, which is the infinite three dots. Even though the obb is definitely there on the headset under Android\obb ...
Kinda at a loss as to what the hell is going on ... and why it isn't able to locate the obb. I can't try packaging the data within the apk as it's over 2Gb and the build fails ...
Any help would be much appreciated ...

Replying to myself for any other weary travelers that may pass this way ...
Issue was with UnrealAndroidFileTool ... our OBB isn't packaged with the APK and is quite large (2.4Gb) ... the new install batch file method of copying to headset uses the UnrealAndroidFileTool by default rather than adb ... and the new method does not seem to like large OBB files ... the copy is only partial leaving a corrupt OBB that is a different size from what the manifest says it is, and this fails the 'does file exist' check in the Unreal bootloader.
Solution is to revert to using adb to install ... setting the following should do the trick ...
[/Script/AndroidFileServerEditor.AndroidFileServerRuntimeSettings]
bEnablePlugin=False
