SL4A is broken and almost abandoned by its developers. There is a problem with the QR code scanning. You can manually extract and copy the e4a zip file from downloads and copy it to the SL4A scripts directory, but you won't be able to scan addresses using QR codes.
Yes, this I noticed also. And I noticed, that this electrum script (e4a.py) is not very stable, or maybe SL4A (r6x03, the last version) is the unstable part.
And electrum for SL4A is not the last version of electrum, is a bit behind, is possible?
Is there plans to use
this Python for Android framework for electrum for android instead of this buggy SL4A-thing?
thank
