Update a native Android app and make it 64-bit compatible

Hi, I need an update on my native Android app (a French-Chinese dictionary). This is what I need: 1. Update every libraries inside the app (google api, sdk, json, and so on…) with latest versions ; 2. Make sure that the new app version support 64-bit devices. 3. Change the version of the app from 4.6 to 5.0 ; 4. Currently, on every page of every (single) Chinese word, we can see a “Info” tab: when we click on it, we can see the Chinese character designed with the “[login to view URL]” font; the tab is displayed only if the character is present in the Character Map file “[login to view URL]”. In this new version, I want : - To delete the check with the “[login to view URL]” file and always display this tab (BUT only if the Chinese word as 1 character and no more) ; - Replace the “[login to view URL]” font with the “[login to view URL]” font that I will provide ; (have a look at "[login to view URL]" file) 5. Create a signed APK file with the [login to view URL] I will provide you. PLEASE, provide the working compiled app, provide the source code of the app, do not sell or redistribute it, do not embed malicious code (malware) or other non-requested feature, and provide a secure and stable application for the user…
