Question

我正在开发使用Secure-Gen Fingerprint SDK的Android应用程序。为此，我使用了 jniLibs ，该应用还具有加密解密功能，因此我使用了 CMake 在 native-lib.cpp 文件中保存一些密码。

当我不使用CMake时，一切正常，但是将两者一起使用会在使用指纹SDK的屏幕上引发异常。

下面是异常的堆栈跟踪：

下面是我的应用程序体系结构的屏幕截图：

我尝试使用以下方法

尝试在abiFilter中添加带有build.gradle的NDK块。
尝试添加 build.gragle文件中的以下代码段

    android {
        splits {
            abi {
                enable true
                reset()
                include 'armeabi-v7a'
            }
        }
    }

试图在android.useDeprecatedNdk=true中添加gradle.properties

以上方法都没有为我工作，但仍然存在异常。

我已经通过分析APK 进行了检查，结果显示这些.so文件已打包。

Answer 1

尝试以下步骤：

1）将所有jniLibs（arm64-v8a，armeabi，x86）文件粘贴到 libs 目录中。

2）在基于应用的gradle文件中编写代码

splits {
    abi {
        enable true
        reset()
        include 'x86', 'armeabi', 'x86_64', 'arm64-v8a'
        universalApk true
    }
}
sourceSets {
    main {
        jniLibs.srcDirs = ["libs"]
    }
}

3）将此行添加到您的依赖项中：

implementation fileTree(include: ['*.jar','*.so'], dir: 'libs')
