Try to add this to your `build.gradle` file.
subprojects { if (project.name.contains('react-native-vector-icons')) { buildscript { repositories { jcenter() maven { url "https://dl.bintray.com/android/android-tools/" } } } } }

Edit your build.gradle as following.
subprojects { subproject -> if (subproject.name.contains('react-native-image-picker')){ buildscript { repositories { maven { url "https://dl.bintray.com/android/android-tools/" } } } } }
