Both "a" and "e" on the DJI RC Pro?

Hi,

I understand that I can't download both the "b" and "e" APK to my DJI RC Pro. However, is there a workaround to download the "a" and "e" to the RC Pro? There is no Google Play on the DJI RC Pro so I can;t get the "a" from the Google Play Store. Is it possible to supply the "a" as an APK?

Regards,

Richard
