Previously, Google considered SD cards to be unsafe and vulnerable, and the Android 4.4 KiKat update made that clear, causing numerous problems for users. The Android developer team seems to have heard the clamor from the streets and solved the situation with Android 5.0 Lollipop. See below what will change in the use of SD cards.
The Android 5.0 Lollipop firmware provides developers with greater access to the SD card. Your applications will be able to create, update and delete files and directories in external memory without requiring user action. For this, Google created the new command ACTION_OPEN_DOCUMENT_TREE. With it, you will now be able to determine the folder (s) on the SD card that a given application can change.
An application like ES File Explorer, for example, can now move and modify files on the SD card, and QuickPic can change your photo folder and just it. This method is safer and faster than the complicated SD card management brought by KitKat 4.4.
