Hi Peter,
I am testing sending of encrypted emails on android devices with supplied demo and getting this crash:
06-13 14:46:28.195: E/AndroidRuntime(10762): Caused by: java.lang.ClassNotFoundException: Didn't find class "javax.mail.Session" on path: DexPathList[[zip file "/data/app/com.didisoft.android-1/base.apk"],nativeLibraryDirectories=[/data/app/com.didisoft.android-1/lib/arm, /vendor/lib, /system/lib]]
I am using the last downloaded library 1.3.20 and the testing routine is simple. After starting I am using the "Send encrypted email option and filling the screen as it is shown in attached screenshot. Params of my server are hardcoded, though it is not important since the crash point is apparently elsewhere.
There are also other problems which I will report as other posts, but possibly they are bound with this one.
Thanks in advance for your attention!
