HERE Maps API Missing Libraries Error

Question

I'm getting the MISSING_LIBRARIES error code when I try to initialize the HERE Maps Android Premium API maps fragment. I followed all the directions here and I'm still getting the same error code. For reference: here is my AndroidManifest:

Please tell me what needs to be done to get rid of this error, I've followed the instructions multiple times now, and I still can't get rid of the error. Thanks!

Answer 1

The MISSING_LIBRARIES error indicates that either the jars or native libraries (in armeabi-v7 folder) required by the SDK are not able to be found.

I know you mentioned you followed the instructions here several times, but just to be sure, please try to follow the "Add HERE SDK Libraries to Your Project" section again.

Specifically:

1. From the directory where you installed the HERE SDK, copy the contents of the HERE-sdk/libs/ folder , except the armeabi-v7a folder, to your project's app/libs/ folder.
2. From the directory where you installed the HERE SDK, copy the contents of the HERE-sdk/libs/armeabi-v7a folder to your project's app/src/main/jniLibs/armeabi folder. You need to create the jniLibs and armeabi subfolders.
3. In your Android Studio project's app/libs/ folder, right-click the *.JAR files and select Add as Library..., then under the Add To module, select app and click OK.
