This is runtime block I have tried android:text which was suggested and also enable multiDexEnabled true in gradle(app) file nut nothing works for me Can anyone help me out?.. **It is simple app only showing weather information from the api key it works on emulator but not on phone **
Blockquote
The error seems to be: Cleartext HTTP traffic to api.openweathermap.org not permitted.
Clear text means any information transmitted that is not encrypted, which means you are either trying to contact the API through an http url instead of https, or that the API of the device where you are running the code is higher than Android 9, where clear text communication was disabled.
Check out the official Android documentation for this and also this question for further information.
