Java – how to use Google Maps API for Android to limit maps to one country / Region

I am completely unfamiliar with Android's Google Maps API. I want to know if it is possible to limit the area displayed in the map to only one country / region. I mean that my target users are only in my own country / region, and it is useless and illogical to show them the whole world when the application logic is only displayed in that country / region

Any ideas?

PS: if it is not possible in Google's API, can it be used with another API through another source that provides mapping services?

resolvent:

If you are still interested, you can now set it to restrict the user's panning to a given area using the setlatlngboundsforcameratarget method

You will need to update the dependencies of the play service:

dependencies {
    compile 'com.google.android.gms:play-services:9.6.1'
}
