Hello, I'm programming with B4A 9.0 and I'm happy with this product (easier than Android Studio). I use a TCP Client socket to communicate with a Wi-Fi ESP8266 access point (no internet connection): "Public CltSock As Socket". Everything works great for Android versions 5 to 8. But no Wi-Fi connection with an Android 9.0 smart phone (Huawei). "Sub Client_Connected (ConStatus As Boolean)" returns "ConStatus" false. In the manifest, I added: "CreateResourceFromFile (Macro, Core.NetworkClearText)" but nothing in Wi-Fi connection (as it is said in https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/page-2. ) Here are the B4a and the Android Manifest file. Thank for help.
