any solution appreciated.
you can add code onresume method. checks if user has updated version of google play services, , if not, popup redirecting him google play shown.
@override protected void onresume() { super.onresume(); int errorcode = googleplayservicesutil.isgoogleplayservicesavailable(this); if(errorcode != connectionresult.success && googleplayservicesutil.isuserrecoverableerror(errorcode)){ dialog d = googleplayservicesutil.geterrordialog(errorcode, this, 0, new oncancellistener() { @override public void oncancel(dialoginterface dialog) { //as application heavy use of maps, if user cancels dialog, finish fragmentactivity mainfragmentactivity.this.finish(); } }); d.show(); } } hope helps, cheers!
