引入Google Play Service

参考：https://developers.google.com/android/guides/setup

配置AndroidManifest

<meta-data android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

<resources>
    <!-- Android-Sdk\extras\google\m2repository\com\google\android\gms\play-services -->
    <integer name="google_play_services_version">12451000</integer>
</resources>

判断Google Play Service是否可用

public static boolean isGooglePlayServicesAvailable(Activity activity) {
    GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
    Integer resultCode = googleApiAvailability.isGooglePlayServicesAvailable(activity);
    if (resultCode != ConnectionResult.SUCCESS) {
        Dialog dialog = googleApiAvailability.getErrorDialog(activity, resultCode, 0);
        if (dialog != null) {
            dialog.show();
        }
        return false;
    }
    return true;
}
