Question

在较新的Android版本中，应用程序无法以UnsatisfiedLinkError异常启动。似乎org.qtproject.qt5.android.QtNative.loadBundledLibraries正在尝试加载版本库，但无法加载！

由于我的app.shell.ShellActivity.onCreate()没有直接加载该库（如下所示，其中否 system.load），我不知道如何解决该库加载失败。

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;
}
}

该库是在.pro中配置的，如下所示，

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

请注意，该应用程序在其他较低的Android版本（已在4.4和5.1上测试）上运行良好，但在Android 9.0（Pie）上无法运行。

堆栈跟踪如下所示。知道如何解决吗？

在SO处提出了一些解决方案，但这是用新的SONAME修补.so文件的方法。在这种情况下，我在小精灵内的SONAME是未版本化的。如果我编辑并添加版本，我想它会破坏已经在较旧的android版本上运行的应用程序，或者完全破坏.so加载/重定位。

有没有主意的原因，为什么没有版本更新的android会尝试加载版本控制的版本？
