Admob ads not loading - Failed to load ad: 0

Question

I am trying to load Admob Native ads. Previously (before app was updated) ads used to show but now they are not showing. I have posted the code, xml and the Logcat below.

Answer 1

From the Documentation, Error code 0 means Internal error.

public static final int ERROR_CODE_INTERNAL_ERROR

Something happened internally; for instance, an invalid response was received from the ad server.

Constant Value: 0

This error generally occurs in newly created ads. So wait for few hours for the ads to be loaded.
