How to clear Media Storage app data programmatically?

Can every Android app with the "Read External Storage" permission access every photo on my phone, along with every other app's saved data?

  • Since almost every app uses this permission, it seems like a mighty big security hole to me.

  • Answer:

    Read external storage permission gives the app access to everything on the SD card. All data stored on the SD card is public data, so it's not violating any privacy. Do check out http://developer.android.com/guide/topics/data/data-storage.html for other ways you can store app data so that it's not available publicly.
