[Interest] Qt Android app crashing on Android 6.0 -

[Turunen Tuukka]

Hi,

When we have been running Android 6 and itse development versions we have not experienced such crashes. The crash you sent is in libcrypto.so though, which is not part of the Android NDK, so if you're using the system version, you're a bit on your own. As we've said in our documentation, you have to bundle OpenSSL with your application if you want to make sure it works with future versions of Android. That said, one of our developers recently tested a Qt example that uses OpenSSL as well, and that also works fine on Android 6.0.

Here's the docs about OpenSSL: http://doc.qt.io/qt-5/opensslsupport.html

Once you have narrowed this down, please make a bug report.

Yours,

	Tuukka
