/home/vagrant/build/de.nproth.pin/app/build.gradle:8: Error: Google Play requires that apps target API level 29 or higher.
 [ExpiredTargetSdkVersion]
        targetSdkVersion 28
        ~~~~~~~~~~~~~~~~~~~

   Explanation for issues of type "ExpiredTargetSdkVersion":
   As of the second half of 2018, Google Play requires that new apps and app
   updates target API level 26 or higher.

   Configuring your app to target a recent API level ensures that users
   benefit from significant security and performance improvements, while still
   allowing your app to run on older Android versions (down to the
   minSdkVersion).

   To update your targetSdkVersion, follow the steps from "Meeting Google Play
   requirements for target API level",
   https://developer.android.com/distribute/best-practices/develop/target-sdk.

1 errors, 0 warnings
Lint found fatal errors while assembling a release target.

To proceed, either fix the issues identified by lint, or modify your build script as follows:
...
android {
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}
...

FAILURE: Build failed with an exception.

Could you please take a look? Thanks!
