Current status

・ Build completed successfully
・ Check on emulator


The following error occurs when debugging the actual machine (confirmed with Vaio Phone A)

  • Answer # 1

    I think it is the same as below.

    FATAL EXCEPTION Android 6 and later maps fall


    Is added to AndroidManifest.xml.
    [Android] Get location information using FusedLocationProviderClient

    The following pages will be helpful when obtaining permissions.
    A little kind of Runtime Permission support
    Referring to the above

    I think it would be good to get permission for these two.
