我正在尝试在我的android应用程序中使用来自另一个存储库(已经准备好使用本机代码)的本机代码。所以我需要将libs output文件夹和java文件从这个存储库放到我的项目中。我遵循了以下程序:
从以前构建的存储库开始:
修改了文件夹结构以及所有相关的源代码文件,以确保包名与我当前的应用程序目标完全匹配。
确保安装了android ndk并包含在path环境变量中。运行“ndk build-b ndk\u debug=0”。已在libs文件夹中获取已编译的库。
将整个libs文件夹(包括我的应用程序项目app\src\main下的所有子文件夹和内容)以及src/the/package/name下的所有java源代码(demo activity类除外)复制到我的应用程序项目的相应位置。
在模块的build.gradle中添加了以下行:

sourceSets.main {
    jni.srcDirs = [] // disable automatic ndk-build call
    jniLibs.srcDir 'src/main/libs/' // integrate your libs from libs instead of jniLibs
}

在我的应用程序中调用复制的java文件中的方法时,出现以下错误:

我不知道为什么会出现这个错误。我已经检查了其他答案的解决方案,并尝试了他们,没有任何运气。另外,我也不知道为什么在这个错误中,它说“尝试了java\u com\u example\u wbd\u 1tws\u 1demo\u androidhrvapijni\u init\u 1hrv\u 1analysis”。为什么1在那里?我的包名是com.example.wbd\u tws\u demo。1正常吗?
