Offline translation files not recognized When I try to use Google Translate offline, I get an error:  


  Translation failed.  Offline translation file not available. Please check SD card is inserted.   


In Settings-> Storage I could see that the Translate app was stored in the phone's internal memory.  I tried moving it to the SD card, and even after restarting the device, the same error was still there.  

Using a file browser, I am able to look at the SD card and see that 
/storage/extSdCard/Android/data/com.google.android.apps.translate/files/olpv3/v5/25/r11 contains folders like dict.en_pt_25, lang.en_pt, and lang.pt_en where "pt" is also replaced by some other two-letter language codes. .../r12 contains the files for French. 

How do I get Translate to work?
In the file browser, at e.g. .../r11, Select All and choose Move, and move them to the similar path on internal memory (which works out to be /storage/emulated/0/Android/data/com.google.android.apps.translate/files/olpv3/v5/25/r11) and also move the other revisions (e.g. .../r12 on the SD card to .../r12 on internal memory).  The app itself can still be running on the SD card, but for some reason it can't find the offline translation files there.
