Android 5.0 offers better access to SD cards for devs
But in recent years, Google has made several changes to how Android was managing access to these cards, limiting the ability of Android applications actually write data to removable storage such as a micro-SD card.
Today, it seems that Google is back to basics, and made some changes that could make micro-SD cards much more useful.
Basically, the changes mean that applications can write data not only in specific directories on a micro-SD card, but also on the whole of this expandable memory . Users will be prompted to grant or deny access to a high standard SD card, and the first time an application requests permission. Once you have made your choice, you will never be able to change it.
There is also a new way for applications to create a specific directory for those, and allow other applications to access data from that file.
If you wonder why you want to leave access to all data for an application on your micro SD card, think about the Camera application, Gallery, or photo editing applications. It is important to know that you can use any application to take a picture and you can use any image editing application to edit the photo, as both can access files stored in shared directories.
Here are some information about the tools for removable storage Android 5.0:
- New methods to access SD cards require Android 5.0, so do not expect to see major changes to the applications running on Android 4.4 or later
- This will be third-party developers to exploit these new tools, so do not expect that all Android 5.0 enjoying the writing and reading enhancers for SD cards
- The first to adopt Android 5.0 probably will not access new features as the Nexus 4, the Nexus 5, the Nexus 6, the Nexus 7, the Nexus 9 and Nexus 10 does not have a port for a microSD card -SD
- You still can not install applications on an SD card. Indeed, applications can only write data to an SD card to store photos, videos or other large files to avoid cluttering your primary storage.
