Android 2.2 issue java.lang.NoSuchMethodError:java.lang.String.isEmpty

Hi . good day !

I have android 2.2 running on Archos 28 internet tablet.

I am having this issue while connecting over wifi.

I am building the project online over internet.
I have downloaded the latest .apk from AppInventor web.
The .apk installs and loads well on this mini tablet.
But it just wont connect.
The error i have mentioned pops up on tablet side.
While in the internet browser, it loads to 20% and halts.


You may need to check the Use Legacy Connection option in the companion on a device running such an old version of Android. Otherwise, it'll take a path through newer code than your device can support.
