Map activity does not show up in my phone because I have many activities

Question

I created new activity which is map activity. I think I have problem in AndroidManofest.xml. My phone works perfectly if I create new project with just map activity. If I add it to my project, which has a lot of activities, it does not work. I do not know why.

the problem is about the activities AndroidManofest.xml

I checked every thing APU is enable

AndroidManofest.xml

Where is your MapActivity registered in manifest .i can't see it there . — ADM, Dec 04 '17 at 10:50
I see it now . Checkout the link above by Nilu . It's the same issue . — ADM, Dec 04 '17 at 10:54
You're probably using the API key from the other project you're creating with just the MapsActivity. You need to generate a new API key from google console using your main project's package name iirc — denvercoder9, Dec 04 '17 at 10:55

    android:name="com.google.android.backup.api_key"
    android:value="backupkey" />

Go to the Google Developer console then click on the 'Enable API's and Services' option along with plus icon on the top of the Dashboard tab.Then there is a 'Google Maps Api' option under the Maps Category,select that then there is 'Manage' option which will enable your google maps apis.

After then you can create the map key for your project using your package name and then use it in your manifest.

Note- After using key please reinstall your app ones to reflect the map changes.
