Found solution for me. Chose obfuscators, the last one is -o Rebuild. Than align obfuscated apk file with zipalign, I used the next command: zipalign -p 4 app-debug_obfuscated.apk outline.apk After that sign outline.apk with apksigner, I used the next command: apksigner sign --ks key.jks signed.apk - you should paste your keystore pass and key pass. And thats all, you receive signed apk.

Hi @trafficteam7, thanks for reporting the issue and the solution. We will use apksigner instead of jarsigner in a future release of Obfuscapk, so issues like this should be solved (hopefully).
