When I try to run https://github.com/Timmmm/MMS on emulator, some error happens:

    java.lang.UnsatisfiedLinkError: Library drmframework_jni not found;tried [/vendor/lib/libdrmframework_jni.so, /system/lib/libdrmframework_jni.so]

    android.drm.DrmManagerClient.<clinit>(DrmManagerClient.java:56)

This is caused by the missing Library drmframework_jni.so. But it does exist in ZTE U950, so it's working there.
