I have made a huge research for resolving this problem and there are two topics just like mine in unity answers but these two can’t also resolve my problem. I tried to set Build System to Gradle, updated sdk, downgraded sdk also did the same for jdk, changed tools folder, put some folders from build-tools to tools I even researched problem as a java error but NO! non of them has resolved my problem. That’s why I’m opening a new question for this issue. Hope somebody can help.
Here it’s my error log:
CommandInvokationFailure: Failed to sign APK package.
