Connecting ATOL KKM to AndroidStudio (update to FZ-54)
Good afternoon, Habr. Last summer, I had to connect ATOL KKM to the project in AndroidStudio. Having successfully coped with the task, I published a post on Habré to ease the way for those who go my way: Connect the ATOL CMC to AndroidStudio .
In light of the legislation update (FZ-54), updated drivers were released for the ATOL KKM, which require a slightly different approach for connection than the one described earlier.

Under the cut, you will see exactly what I did. But I’ll say right away that the Android development pro will probably not find anything interesting for themselves, but for beginners like me, it will ease the development path a little.
To connect the updated drivers, the following steps were taken:
1) Delete the old module from the project: File - Project Structure - select the old module from the Modules section, and click on the red minus;
2) Added a new module: File - New - Import Module - look for the folder (in the provided folder, I have: Trade_equipment_drivers / android / jar) FptrLibRes and add it to the project;
3) Further, as in the previous article, add to jniLibs (path: app / src / main), folders armeabi and armeabi-v7a;
4) Add to the libs folder (path: app / src / main) - jar files: fptrlib.jar, fptrproxylib.jar, paycardlib.jar, usblib.jar Right-click on the jar-files, and select "Add As Library ";
5) We make changes to gradle (I give an example from a test project that was created for the last article):
6) From the manifest, delete the lines (if they were, as in the last test project):
7) Errors will appear in the code. To fix, change:
It will also give an error to operators containing the words "Reciept". They need to change to "Receipt".
Sample test application:
Next, we work on the official manual.
So let me leave. I hope someone will save time and nerves. If someone has comments and prompts, with great pleasure I will listen to them.
PS: I recently got the opportunity to test my application on a device with API23. When creating and reading a file, it constantly caught an exception. So I faced a new security policy regarding permissions. A wonderful article from OneeL : Android runtime permissions helped me figure this out . Why, why and how .
Having estimated that the capabilities of API23 in my application seem to be useless, I lowered targetSdkVersion to 22. In this case, everything began to work fine.

To fix, change:
fptr = new IFptr(); fptr = new Fptr(); It will also give an error to operators containing the words "Reciept". They need to change to "Receipt".
