当我尝试初始化 HERE Maps Android Premium API map fragment 时，收到 MISSING_LIBRARIES 错误代码。我遵循了所有指示here我仍然收到相同的错误代码。供引用:这是我的 AndroidManifest:

The API key for Google Maps-based APIs is defined as a string resource.
(See the file "res/values/google_maps_api.xml").
Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.

请告诉我需要做什么才能消除此错误，我已经按照说明多次操作，但仍然无法消除该错误。谢谢!
最佳答案
MISSING_LIBRARIES 错误表示无法找到 SDK 所需的 jar 或 native 库(位于armeabi-v7 文件夹中)。
我知道您提到过您遵循了说明 here多次，但为了确定，请尝试按照 "Add HERE SDK Libraries to Your Project" 进行操作再次部分。
具体:
- 从安装 HERE SDK 的目录中，将 HERE-sdk/libs/文件夹的内容(armeabi-v7a 文件夹除外)复制到项目的 app/libs/文件夹中。
- 从安装 HERE SDK 的目录中，将 HERE-sdk/libs/armeabi-v7a 文件夹的内容复制到项目的 app/src/main/jniLibs/armeabi 文件夹中。您需要创建 jniLibs 和armeabi 子文件夹。
- 在 Android Studio 项目的 app/libs/文件夹中，右键单击 *.JAR 文件并选择“添加为库...”，然后在“添加到”模块下选择应用并单击“确定”。
