集成Easeui报错,com.android.dex.DexException

Error:Error converting bytecode to dex:
Cause: com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;
 
这个是v4包重复吗,我在网上查好像是说重复,但是不知道哪里重复了,还是其他问题,
 
app:

dependencies { 
compile fileTree(include: ['*.jar'], dir: 'libs') 
testCompile 'junit:junit:4.12' 
compile 'com.android.support:appcompat-v7:23.3.0' 
compile project(':easeui') }
 
easeui:

dependencies { 
//release时需要把easemobchatsdk的依赖注释掉，sdk已经被打成jar包放在libs底下 
//compile project(':hyphenatechatsdk') 
compile fileTree(dir: 'libs', include: '*.jar') }
 
 
求解答,谢谢
