Answer 1

You have to require signed apk with SHA-1

Step 1:

Now locate to jdk in C drive(Considering for windows and assigning C drive)

C:Program FilesJavajdk1.7.0in>keytool -list -v -keystore E:A.keystore -alias A

So it will create SHA-1 finger print

Step 2:

    Go to google api console.
    Generate new api key for android you have to used this SHA-1 and current playstore package name.
    Put Api key into your map.

I hope this is enough for you.If any query put comment.
