java.lang.UnsatisfiedLinkError：dlopen失败：库“/system/lib/libssl.so”

Question

我试图在我的Android应用程序中加载OpenSSL .so文件，但它正在抛出UnsatisfiedLinkError。

MyCode：

public class MainActivity extends AppCompatActivity {

static {
    System.loadLibrary("ssl");
    System.loadLibrary("crypto");
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}}

例外：

                        ${log-lib} )

这高于我的代码和例外。我还在CMakeList.txt中导入.SO（s），但我无法找到问题的确切问题，因为我还将.SO（s）放在了libs文件夹中。

请建议我一些解决方案。

Answer 1

我的坏，我通过添加$ {ANDROID_ABI}来解决它，我忘了将.SO放在ABI文件夹中。

set(distribution_DIR ${PROJECT_SOURCE_DIR}/src/main/cpp/${ANDROID_ABI})
