In the readme that contains this part using gradle 4 and 5 will have problems.

2. Add the compile line to dependencies in android/app/build.gradle

...
dependencies {
    ...
    compile project(':react-native-activity-recognition')
    ...
}

WARNING: Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'. It will be removed in version 5.0 of the Android Gradle plugin.
