Using getExternalStorageDirectory not resolves the problem, in the source code he copies trained data from assetManager to the root folder of android. For me it's not good solution. If I can pass path from the tessdata directory direct from my AssetManager or using another approach that not uses statical paths(including external paths from the app such as getExternalStorageDirectory ) or do copies would better.
The better solution would add trained languages in the app and use them without any copy or acessing external paths. The AssetManager would be a good solution, i can create a tessdata folder and insert all trained data. But i don't know how to get path from AssetManager that i can put to the tesseract initialization. if anyone has any ideas would greatly help my progress, thanks.
