Could not resolve all artifacts for configuration ':react-native-document-picker:classpath'.
If you don't want to wait until this library will release fixed version, here
is how you can fix it:
Just add it to your build.gradle under subprojects section in the root (not app/gradle)
subprojects {
if (project.name.contains('react-native-document-picker')) {
buildscript {
repositories {
jcenter()
maven { url "https://dl.bintray.com/android/android-tools/" }
}
}
}
}
