当我尝试初始化HERE Maps Android Premium API地图片段时，我收到了MISSING_LIBRARIES错误代码。我按照所有路线here进行操作，我仍然得到相同的错误代码。供参考：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/.

请告诉我需要做些什么才能摆脱这个错误，我现在多次按照说明操作，但我仍然无法摆脱错误。谢谢！
答案 0 :(得分：3)
MISSING_LIBRARIES错误表示无法找到SDK所需的jar或本机库（在armeabi-v7文件夹中）。
我知道您曾多次按照说明here提到您，但为了确定，请再次尝试关注"Add HERE SDK Libraries to Your Project"部分。
具体做法是：
