[Interest] Android 7 issues

[Federico Buti]

Yeah, that's a shame.
I've resorted to use a linux box to compile openssl 1.0.2j; everything went
smoothly and I got my libraries. Then I've modified the .pro file as
follows (according also to this
<http://stackoverflow.com/a/25177281/2538363>):

LIBS += $$PWD/lib/droid/libcrypto.so $$PWD/lib/droid/libssl.so

        PRE_TARGETDEPS += $$PWD/lib/droid/libcrypto.a

        INCLUDEPATH += $$PWD/include/openssl

        INCLUDEPATH += $$PWD/include/openssl

        # ADDITIONAL ANDROID SETTING                        # seems to
be not needed

        #ANDROID_EXTRA_LIBS = $$PWD/lib/droid/libcrypto.so

        #ANDROID_EXTRA_LIBS = $$PWD/lib/droid/libssl.so



I'm just doing a post (application/x-www-form-urlencoded) to a rest service
which works fine on Windows (libeay32.dll/ssleay32.dll) and other
platforms. Still, on android I got the error (via errorString()):


DEB Error string "Error creating SSL context (unsupported protocol)"


The same error occurs in both in a 4.4 and in a 6.0 devices. On the 4.4
device, executing the app without the linked SSL lib result in the same
error. It's like the application is linking to the built-in openssl
library, disregarding my libs. Adding the commented line for extra libs
does not change anything.

Any clue? Did I miss something? The guy from the linked answer warns that
only 0.9.8za worked for him. Is that really true?

Thanks in advance,
F.
