We are using the version more than 2 years ago(4.12.3)，which also have some crash issue，we want to update to new versions to fix these crash issue, but the new versions have above serious issue, we are unable to apply it. while the Android SDK have no problems on the new versions, hope you can fix the problem as soon as possible
