Android: minification obfuscating dynamically accessed classes

I am using Samsung's Motion library to create a pedometer for Samsung phones. When I create an APK without minification in the gradle configuration file the system works. However when I try to apply minification before releasing to the store, 

buildTypes {
    release {
        minifyEnabled true
        signingConfig signingConfigs.config
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        debuggable false
        jniDebuggable false
    }

I got errors claiming the some libraries (e.g. android.hardware.motion) do not exist. I have checked and:

If I remove the line minifyEnabled true I got no error, so it must be the code obfuscation.

I have tried to add to my proguard rules file statements such as 

-keep class android.hardware.** { *; }
-keep class com.samsung.android.sdk.** { *; }

but this does not seem to work. Any idea? Thanks!

The missing classes are indeed only available on the actual device. In order to let ProGuard process your application, you will have to include the following configuration:

-dontwarn com.samsung.android.sdk.motion.**
-dontnote com.samsung.android.sdk.motion.**

This will ignore the warnings and notes originating from the samsung sdk.
