Store / Load Filles in External SD Card By Default

[hallahan]

Interestingly, there is no way to do this in the Android SDK, and Stack Overflow has been misleading.

However, I found the VLC app on Github that does access the SD card, and I found code that lets me do it. I implemented those util functions.

We need to use this and have OpenMapKit store things in the SD card by default, and fall back on standard "external" storage as secondary.

https://github.com/mapsme/omim/blob/master/android/src/com/mapswithme/maps/settings/StorageUtils.java

Also, MAPS.ME has similar code, though it's a little less reusable:

https://github.com/mapsme/omim/blob/32f28f0aa4bc7a0564e002f84d292c6dd1849eaa/android/src/com/mapswithme/maps/settings/StoragePathManager.java

When implementing #19 we should do this.

Though I'm able to access the SD card now, I'm unable to create directories in the SD card. Needs further investigation.

Continuing to use external storage until this is resolved (not SD Card).

Also, DownloadManager.Request doesn't seem to have the ability to write to anything that isn't standard external storage.

How about https://developer.android.com/reference/android/app/DownloadManager.Request#setDestinationUri(android.net.Uri)

It lets you set any target for downloading as long as

• the target url is a file uri (file://...)
• it's not an 'internal' target location
• the initiating client has write permission for the target

Did you call File.getCanonicalFile() before trying to create a subfolder on the SD card..?
