Thanks in advance!
I have been trying to run the simple heremaps example apps in android studio 3.0.1 using my phone Redmi 4 (marshmallow), but everytime I face this issue ->
ERROR : Cannot initialize map with error : UNKNOWN
And then the on clicking any button the app simply crashes. I have googled a lot and have performed all the steps correctly.
- step 1.
download HERE-sdk.aar into app/libs folder
- step 2.
setting build.gradle
- step 3.
setting app id, app token, license key. The package name in the same in my app and the heremaps website.
Here is the code of AndroidManifest.xml:
