CPP files don't get compiled

There is a problem with compiling the C code.

When adding this entry in grade build:

externalNativeBuild {
        cmake {
            path "src/main/cpp/CMakeLists.txt"
        }
    }

And syncing gradle I get this error message:

Gradle project cmake.path is /Users/houmie/projects/t-android/app/src/main/cpp/CMakeLists.txt but that file doesn't exist
Gradle project cmake.path is /Users/houmie/projects/t-android/app/src/main/cpp/CMakeLists.txt but that file doesn't exist

I went then ahead and created the cpp directory and placed an empty text file called CMakeLists.txt. Then I could sync the gradle.

Then I ran:

./gradlew hideSecret -Pkey=Houmie -PkeyName=YourSecretKeyName 

It creates four files under cpp folder. secrets.cpp, sha256.cpp + headers. Secrets is also generated for Kotlin.

So far so good, but when I run it in the project:

val key = Secrets().getYourSecretKeyName(packageName)

It crashes:

java.lang.UnsatisfiedLinkError: dlopen failed: library "libsecrets.so" not found

It hasn’t built it. What am I missing please? Thank you

@ben-j69 I just tested it again. I deleted the cpp folder and ran ./gradlew hideSecret. And it syncs the files over. You were right.

The steps you mentioned is correct. Yesterday I had mistakenly added externalNativeBuild in gradle before running ./gradlew hideSecret. This caused the issue. So the documentation is correct, I didn’t pay enough attention. 😃

Thank you for recommending Cocopods Keys, I will try it out.

@houmie thanks for your feedback.
