[BUG] Android 5 devices crashing with UnsatisfiedLinkError libcurl.so

[bigahega]

Describe the bug
Wanted to use the new native library dependencies but apparently Android 5 devices are not happy with this and they are all crashing.

To Reproduce
build.gradle

implementation 'com.android.ndk.thirdparty:openssl:1.1.1g-alpha-1'
implementation 'com.android.ndk.thirdparty:curl:7.69.1-alpha-1'

CMakeLists.txt

find_package(curl REQUIRED CONFIG)
...
target_link_libraries(
        ...
        curl::curl
)

Kt side:

    init {
        try {
            System.loadLibrary("mylib")
        } catch (ignored: UnsatisfiedLinkError) {
            ReLinker.loadLibrary(context, "mylib")
        }
    }

Release build (app bundle)
Android 5 devices: Crash.

Expected behavior
Should not crash like the rest of the Android 6-10 versions?

Is it stated in somewhere that API 21-22 is not supported in these openssl / lib curl releases or am I missing something here?

Also it would be lovely to be able to use the OpenSSL without libcurl.

Interesting. I'll try to find some time to take a look, but unfortunately I have quite a few other things I need to clear off my todo list before I can put much time into these packages.

Also it would be lovely to be able to use the OpenSSL without libcurl.

Why can't you?

Well I don't wanna digress from the original problem here but about that, as far as I remember when I tried adding only the openssl dependency and openssl::openssl instead of the curl::curl, I wasn't able to compile it because of a linker error complaining about openssl. However, adding the libcurl dependency and linking with libcurl instead of the openssl was alright. I will give it another shot and add some more details about the error when I have some spare time.

[DanAlbert]

File another bug for that if you have more info. I haven't actually tried doing that afair but I would expect it to work.

[DanAlbert]

The libcrypto.so in the OpenSSL package definitely has that symbol.

IIRC before M system libraries would be loaded preferentially to libraries in the app if they had the same name, so we're getting /system/lib/libcrypto.so instead of the one in the app :(

Will need to think about how to solve that. Presumably just by making sure every library gets an _ndkports suffix or something like that.

+1 on this issue.
got exactly same error on FireTV sticker (second generation) api level 22 and any Android 5 emulator.

[weikano]

any progress on this issue?

[DanAlbert]

No. We'll post an update when we have progress, but we're currently busy with other issues.
