Crash on Samsung Galaxy A12 / Android 11

Description: Opening the email composer crashes the app on android 11 (Samsung Galaxy A12 on Android 11 is a repro case). I also tried to open the email composer with only the subject given, but had the same result.

Exception is:

I just realized that on the master branch, there was already a bug report open (#361) that got fixed with #368. I checked again which version of the plugin I used and it seems to be the most recent one. However, comparing the code against the master branch in getDraft, there was a difference which was considered the fix in #361/#368.

So I'm wondering, when the fix will be officially released in npm?

You are installing this plugin from npm, try to install it directly from this (original) repo

cordova plugin add https://github.com/katzer/cordova-plugin-email-composer.git

Tell me if this works

[m1cster]

Yes, it fixed it! Thank you!!

you are welcomed, we send to NPM after more fixes and after we are sure this version is stable. Right now, you made us further believe it is :)
