I have two app which use the same package of images. The size of images is 50 Mb. I would like to use these images in both apps but download it only in the internal storage of one of them. Is possible to do this? I know that I can solve this downloading the images in sd card, but in this case I need to download it in internal storage.

If you own both applications, the simplest (and secure) solution is probably to declare a sharedUserId :
If this attribute is set to the same value for two or more applications, they will all share the same ID — provided that they are also signed by the same certificate. Application with the same user ID can access each other's data and, if desired, run in the same process.

This worked for me! Also was helpful for me http://stackoverflow.com/questions/16269956/two-app-with-shared-userid – rei_ayanami Jan 12 '16 at 12:46

internal storage has/had the possibility to set a flag for world readable/writeable, but it is deprecated since api level 17.
another solution is to use content providers which contains your data you want to share. via a content resolver you are able to access these data.
