Couldn't load easemob_jni

 E/AndroidRuntime(4259): java.lang.UnsatisfiedLinkError: Couldn't load easemob_jni from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.baidao.ytxcrm-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.baidao.ytxcrm-1, /vendor/lib, /system/lib]]]: findLibrary returned null

我把libeasemob_jni.so已经放到jni文件夹下了，为什么报这个错，哪位大神帮个忙解决这个问题呢
