After looking into it, it basically is saying the items don't exist and it can't save either.
Okay then. It is easier with newer versions. The issues are likely about some safety stuff as far as I can see. Althou it doesn't seems that at first glance.
I mean, it is more about the plugins. I made it with a good amount of plugins but I tested all them before build the final APK. I had to replace some of them due some js errors. So yeah it depends on how the plugins are made. Some works just fine others doesn't so much
