Can't package empty Android project for Shipping

VinnyBlood · October 24, 2017, 1:09pm

I can’t package empty Android project for Shipping.

SDK is isntalled in default directory (1R6u1).
I create empty bluprint project.
I unckeck “Use Gradle instead of Ant”
I set up project for Shipping

I copy key android file in Build/Android directory.
I successfully package project in Development mode. No errors.
I switch build configuration to “Shipping” and packaging fails. Here’s my log:

In 4.17 same steps works fine.

I tried this on 2 different PC’s. Fails at bothof them

I have the same problem. A game that I could package without problem in Android Shipping configuration using UE4.17 now fails during packaging with proguard-related errors.
The only workaround I found is to edit Build/Android/project.properties and comment out the line “proguard.config=…”. Then the packaging completes without errors.
I’m writing this as a comment rather than an answer, because I have no idea what the consequences might be as I don’t know what proguard is used for. Use with caution

Xaser3D · November 16, 2017, 8:12am

I have the same Error in UnrealEngine 4.18.1 no problem in 4.17

Can you post the log on C:\Users\butte\AppData\Roaming\Unreal Engine\AutomationTool\Logs\E+Program+Files+Epic+Games+UE_4.18\UAT_Log.txt

also it seems it is complaining about some warnings:

omg… It actually worked. Thanks A lot

Same issue here…

Xaser3D · November 28, 2017, 5:49pm

install latest android code work… for update find and run android.bat in android sdk

rcortese · November 29, 2017, 2:57pm

Tried updating CodeWorks with Android.bat, but now I get an unsupported version error (log attached).
(NDK = ‘android-19’; SDK = ‘matchndk’)

Also tried updating Proguard as instructed somewhere else, next attempt is fully migrating assets to a new project

Xaser3D · November 29, 2017, 3:16pm

Min SDK version for today is 21. Proguard is updated automatically after you check all necessary updates in android.bat. You need to set SDK to use 21 Lollipop and edit project.properties if necessary.You may still need to import/migrate your project manually from older version because Unreal unable to convert all you’re setting in 4.18

rcortese · November 29, 2017, 5:26pm

Still no success. Tried the following:

Update Platform SDKs only // Result: Proguard error
Setting MinSDK = 21; TargetSDK = 24; SDKAPI = ‘android-24’; NDK API = ‘android-24’ (as well as many combinations of versions [19-24]) // Result: no difference whatsoever
Update Android SDK Tools (25.2.3 → 25.2.5) // Result: unsupported version error

I have manually migrated my project and reconfigured everything by hand. No help as well

I haven’t found how to use -dontwarn on proguard yet, but am going to. Seems more promising

rcortese · November 29, 2017, 6:34pm

Got it to package!!!

Just add " -dontwarn com.google.protobuf.** " to the last line of

Thank you … after hours and hours of searching …
