No guarantee but i may upload a video of how to package, sign and upload and get a game on google play store (basically everything after your finished developing the game). Then maybe a seperate video for AdMob/Google Play Game Services (Achievements/Leaderboard).
Yeah, it took me a LOOOONNNGGGG time to finally figure this out, even after reading much of the documentation. I’m assuming that this is only a problem for people who have never ever created a mobile application. Even after reading all of the documents about signing apks, I was still pretty unsure. Then I watched this quick video:
It basically covers the steps outlined in another link that was cited here ( Sign your app | Android Developers ) but I guess I’m the kind of person who needs to see someone do it first. I didn’t realize you had to access the keytool from the command line until I watched the video I linked to above.
Anyway, after I watched that basic video, and after I was able to reproduce it, and do the same thing, I was still unsure of what to do. Then I read the following post:
That post tells you how to alter the main SigningConfig.xml file. I did that in notepad. I then saved it to my project’s folder. Then, when I went to build the project for shipping, it finally worked!
However, even though I was finally able to upload my .apk to Google Play, I have not been able to figure out how to upload the .obb files. I was live-chatting with their help, and they were like, “when you upload your .apk, it will ask you to upload your extension files”, but I did that so many times, and have not yet seen anything asking me to upload the extension files. So, good luck with that.
This is it. This way you will sign your APK file so you can upload it to the Google Play Store and it will be signed. Ill update this topic to add some screenshots of the process with the above you should be able to sign your APK file.
Not sure if you still need help with this but I would like to ad my experience in hopes it’ll help.
I have NEVER gotten unreal 4 to successfully sign an apk for me. Not sure what i’m doing wrong but I ended up doing it manually which takes me about a minute.
package for android (I use etc1 for max compatibility).
Once its made I move it to my jdk bin folder (which is C:\NVPACK\jdk1.6.0_45\bin on my computer).
Once its there I press shift+right click and open a cmd window.
Once I have that open, I simply follow the steps at the bottom of the page here: http://developer.android.com/tools/publishing/app-signing.html under Signing your APP Manually
Don’t forget to also zipalign your apk.
Ive done this multiple times for our game Lux Protocol, which is now on google play. Hopefully it helps as this took me forever to figure out.
Since this thread is a bit scattered and the process for .apk signing has changed since it was started, I created an Unreal Wiki page that goes step by step through the most current process (as of Unreal 4.12). Link here:
These instructions are based on my own experience struggling to correctly sign an .apk app for distribution recently. If you find any errors or omissions in this walkthrough, please let me know and I’ll do my best to correct it ASAP.
Hi Monotoan, thanks very much for making this Wiki - as this part of the process has had me stumped. So there is one step I also need to make which was messing me up and that is the Android manifest. Is this something that you can help with too please?
