Nickelgrass Active Member Licensed User Longtime User Jul 16, 2025 #1 Hello, I have a simple app that works on my phone. It just checks if a website is online by downloading it via HttpJob. Now I installed it on my android TV with the B4A bridge. Installing and running works nicly. But the app crashes with "java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/client/methods/HttpGet;". How can I solve this? Or can I use something else to check if the page is online? Thanks Regards

Maybe you are using https://www.b4x.com/android/forum/threads/httputils2-web-services-are-now-even-simpler.18992/ ? See the 1st sentence in this thread HttpUtils2 was replaced with OkHttpUtils2: https://www.b4x.com/android/forum/threads/okhttp-replaces-the-http-library.54723/ Both libraries are included in the IDE.
