+This is a list of common Android build issues and how to resolve them:
+* Gradle plugin 4.X not supported, please install 5.X
+
+	-> Change the version in the gradle-wrapper.properties file
+* MinSdkVersion/TargetSdkVersion not supported in AndroidManifest.xml
+
+	-> Remove both versions from AndroidManifest.xml as suggested by Android Studio (as they are taken from build.gradle only since Gradle 5)
+* Command "compile" is obsolete, use implementation instead
+
+	-> Change all dependency declarations to use "implementation" instead of "compile" to support the latest gradle changes - https://github.com/Jumio/mobile-cordova/blob/master/demo/platforms/android/build.gradle#L291
+* Theme.Netverify/Bam/DocumentVerification/Authentication cannot be resolved
+
+	-> Add the Jumio dependencies as proposed here: https://github.com/Jumio/mobile-cordova/blob/master/demo/platforms/android/build.gradle#L95
+* Ressources from styles.xml "cornerRadius" and others not found
+
+  -> Build tools and support library are not at version 28. Change compileSdk and buildToolsVersion as described here -> https://github.com/Jumio/mobile-cordova/blob/master/demo/platforms/android/build.gradle#L222
+* Device-ready not fired after X seconds
+
+  -> The plugin definition in "YOURPROJECT/platforms/android/platform_www/plugins/cordova-plugin-jumio-mobilesdk/www" might be duplicated/corrupted due to the issue mentioned in this Stackoverflow post - https://stackoverflow.com/questions/28017540/cordova-plugin-javascript-gets-corrupted-when-added-to-project/28264312#28264312 , please fix the duplicated "cordova.define()" call in these files as mentioned in the post.
