Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 19 declared in library [androidx.lifecycle:lifecycle-livedata-core:2.8.0-alpha01] C:\Users\gideo\.gradle\caches\transforms-3\c77661fbbe9852b1e5ccd34f49c507f9\transformed\lifecycle-livedata-core-2.8.0-alpha01\AndroidManifest.xml as the library might be using APIs not available in 15
Suggestion: use a compatible library with a minSdk of at most 15,
or increase this project's minSdk version to at least 19,
or use tools:overrideLibrary="androidx.lifecycle.livedata.core" to force usage (may lead to runtime failures)
