Signal doesn't run on Kitkat, because it cannot link aesgcm

[raph431]

Is there any chance I can make this library work on Android 4.4.4?
I have an old Samsung GT-S5830i and cannot find a Lollipop update.

Signal startup fails with
W/dalvikvm( 4870): Exception Ljava/lang/UnsatisfiedLinkError; thrown while initializing Lorg/signal/aesgcmprovider/AesGcmProvider;
unless I use Signal version 4.36.2, which cannot send any messages anymore.
