UnsatisfiedLinkError from qt5.android.QtNative.loadBundledLibraries on Android Pie

JImson James

In newer Android versions, the application is failing to start with UnsatisfiedLinkError exception.
It looks like the org.qtproject.qt5.android.QtNative.loadBundledLibraries is trying to load the versioned library but is not able to!

Since my app.shell.ShellActivity.onCreate() is not loading the lib directly (shown below), I dont have any idea how to tackle this lib loading failure.

public class ShellActivity extends QtActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

    if (running) {
        Log.e(TAG, "An instance of this activity is already running!");
        setResult(-2);
        finish();
        System.exit(-2);
        return;
    }
    running = true;
}

}

The lib is configured in .pro as shown below,

app_android: contains(ANDROID_TARGET_ARCH,armeabi-v7a) {
LIBS += -L$$PWD/lib/android/ -lcrypto -lssl
ANDROID_EXTRA_LIBS =
$$PWD/lib/android/libcrypto.so
$$PWD/lib/android/libssl.so
}

CONFIG += app_android

Please note that the application is running fine in other lower android versions, (tested on 4.4, and 5.1) but failing on Android 9.0 (Pie).
objdump output.
file format elf32-little
NEEDED libdl.so
NEEDED libc.so
SONAME libcrypto.so

The stacktrace is as shown below. Any idea how to solve it?

Ive always built my libs without versions, then linked with them directly.

Linking works..
apk got created...
App works perfectly in 4.4 (android-19) and 5.1 (android-21).
But when i tested it on 9.0 (Android Pie), app crashed.

So I guess org.qtproject.qt5.android.QtNative.loadBundledLibraries has something to do with library loading (versioned and non-versioned) in latest android versions (Atleast I know my app is crashing on Android Pie).
