Aviary has updated their plugin app for the Google Android platform.
Aviary Photo Editor now supports image sizes up to 8 megapixels. This means that in most cases you would be able to save modified images in their original resolution.
Fixed a bug which kept edited images from showing up in the gallery.
New settings panel, which includes the option to choose a destination folder for your saved images.
Aviary Photo Editor works as a plugin on your phone. There is no dedicated app that you can open and use. You share your images from third party apps into this plugin to use its features.
