Answer 1

You will need to go through the checklist below and your issue will (probably) be fixed:

• Check if the package and class name is written properly in your layout XML file
• If your project has multiple modules, check for availability of the class com.example.awais.mapapp1.CustomAutoCompleteTextView in the module where it is being used in the layout XML
• If you are using ProGuard/DexGuard or any such tools, ensure that it is not being renamed while the XML is untouched (that should ideally never happen).
