Android build failing after update to React Native 0.58.3

After updating to React Native 0.58.3 the Android build is failing. See enclosed log file. There seem to be resources missing for Android 9.

I also encountered this error. It seems that RN updated Android SDK to 28 in 0.58.* while this library still using 27.

FYI, there're some methods to fix it.

• Modify compileSdkVersion and targetSdkVersion in file node_modules/react-native-picker/android/build.gradle to 28 manually. Just make sure its value before every build.

• Refactor the code in node_modules/react-native-picker/android/build.gradle to get versions dynamically:

  def safeExtGet(prop, fallback) {
    rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
  }
  
  android {
    compileSdkVersion safeExtGet('compileSdkVersion', 27)
    buildToolsVersion safeExtGet('buildToolsVersion', '23.0.1')
  
    defaultConfig {
        minSdkVersion safeExtGet('minSdkVersion', 16)
        targetSdkVersion safeExtGet('targetSdkVersion', 27)
        // ...
    }
    // ...
  }

  And in your project's level build.gradle, provide these values:

  buildscript {
  ext {
    targetSdkVersion = 28
    compileSdkVersion = 28
    minSdkVersion = 19
  }
  // ...
  }
