Method to scale down the bitmap
The system Gallery application displays photos taken using your Android devices's camera which are typically much higher resolution than the screen density of your device
Given that you are working with limited memory, ideally you only want to load a lower resolution version in memory. The lower resolution version should match the size of the UI component that displays it. An image with a higher resolution does not provide any visible benefit, but still takes up precious memory and incurs additional performance overhead due to additional on the fly scaling.
This method used to decode large bitmaps without exceeding the per application memory limit by loading a smaller subsampled version in memory

If you want to use custom resource in your App you can override default resource. For that you have to place your custom resource inside app_root/platform/android/res or app_root/modules/android/titutorial.gallerypicker/0.1/platform/android/res in the same name.
For example, if you want to override default image in Gallery item you have to override your custom image with name of no_media.png
