Answer 1

If you changed API key in manifest just

• clear data (in android device)

or

• uninstall app and reinstall it

Answer 2

Try to add this permission to to your manifest

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Answer 3

From the Manifest file you posted it looks like you package name: package="com.com.my_package_name"

does not match the package name you used for Google Maps permissions:

<permission
    android:name="com.my_package_name.permission.MAPS_RECEIVE"
    android:protectionLevel="signature"/>
<uses-permission android:name="com.my_package_name.permission.MAPS_RECEIVE/>

You can see that com.com.my_package_name is different from com.my_package_name, this must be your problem.

Answer 4

There are two keys debug and release key. If you signed your apk you want to use release key. I think you used debug key. So only map looks blank. Release key procedures are here.
