Is there any other way available to integrate map easily in android, iPhone and Window phone using xamarin ?

Answer 1

If you're using Visual Studio;

Right-click your Droid project, go to the Android Options tab, click Advanced and set Java Max Heap Size to 1G

If you're using Xamarin Studio it should be something similar.

It has to do with all the Java bindings that are being loaded and it loads up to much memory. With this setting you increase the default memory available.

You can read more about it in the relevant bug in Xamarin from a while back here; https://bugzilla.xamarin.com/show_bug.cgi?id=8137#c14

Answer 2

There are 2 possible causes.

1. Your emulator has very low memory, you can increase that
2. You may have some large images showing on Android. Android doesn't do well with images, make sure you shrink them to the correct size.

With your new error messages, go to the directory with the issues and delete all the zip files and contents. VS or Xamarin will download them automatically again.

Also update your compile API target to API 23, you can keep the minimum at 15 though.
