App not installed Hello,(i have copied this thread to the appropriate subforum) I have written a simple test app that displays the text “test” in a textview. The app works in the emulator on the same android version. On my android device it will not install saying “app not installed” after attempted installation. I have already allowed unknown apps to be installed, and allowed “my files” as a trusted source. I have turned off play protect and restarted. Does anyone know a possible solution? Greetings, Stefan...
