Answer 1

use this method:

     //HashKey Generator
public static String getProjectHashKey(Context context) {
    String hashKey = "";
    try {
        PackageInfo info = context.getPackageManager().getPackageInfo(
                context.getPackageName(),
                PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            hashKey = Base64.encodeToString(md.digest(), Base64.DEFAULT);
            Log.d("KeyHash:", hashKey);
        }
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    return hashKey;
}
