2 weeks ago Seeing an error when building the apk. Something to do with the environmental variable for the SDK:
cd qt/android && gradle wrapper --gradle-version=6.6.1
openjdk version "21.0.3" 2024-04-16
OpenJDK Runtime Environment (build 21.0.3+9-Ubuntu-1ubuntu1)
OpenJDK 64-Bit Server VM (build 21.0.3+9-Ubuntu-1ubuntu1, mixed mode, sharing)
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring root project 'android'.
> SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
