Android AppCompat Library V7 » 28.0.0-alpha1. The Support Library is a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs. Compatible on devices running API 14 or later. Hi B4a 6 was working properly them suddenly every time I open it gives me missing to library themes.xml. However when I check the library folder it is there but not the jar file. Also don't know where to get android-support-v7-appCompat.jar. In the new library project, expand the libs/ folder, right-click each.jar file and select Build Path Add to Build Path. For example, when creating the the v7 appcompat project, add both the android-support-v4.jar and android-support-v7-appcompat.jar files to the build path. (don't import v4 now. Download JAR files for android.support.v7 With dependencies Documentation Source code All Downloads are FREE. Search and download functionalities are using the official Maven repository.
-->Make sure you download the latest extras as well as the Android 5.0 (API 21) SDK via the Android SDK Manager.
Ensure that you are compiling your application with compileSdkVersion set to 21. You can optionally set the targetSdkVersion to 21 as well.
