I had the same or at least a very similar problem today with our React Native app. The problem was only on my Mac though. The only plausible explanation we could think of was that I updated a bunch of Android Studio tools and then gradle couldn't build properly with our dependencies. Anyways after excluding the pom.properties and pom.xml from okhttp I kept getting the same error but it turns out that I just had to exclude even more files. This is my complete packagingOptions in build.gradle:

packagingOptions {
  exclude 'META-INF/maven/com.squareup.okhttp3/okhttp/pom.properties'
  exclude 'META-INF/maven/com.squareup.okio/okio/pom.xml'
  exclude 'META-INF/maven/com.squareup.okhttp3/okhttp/pom.xml'
  exclude 'META-INF/maven/com.squareup.okio/okio/pom.properties'
}

to solve your problem please add this to your build gradle

packagingOptions {
    exclude 'META-INF/pom.properties' /*OR*/ 'META-INF/maven/com.squareup.okhttp/okhttp/pom.properties
}

hi thanks for the answer. i try that but same problem i got an error – Denver Bautista Apr 19 '16 at 02:56
/*OR*/ try one of them, and see if the new error is referring to the same file, because you might end up excluding loads of files because of duplicates. – Kosh Apr 19 '16 at 02:58
i tried both same problem i got 2 error post above. – Denver Bautista Apr 19 '16 at 03:06

It seems like okhttp and crashlytics don't work together in newer gradle versions (2.10 in my case). I fixed this by updating the crashlytics to a newer version (which is now called Fabric).

packagingOptions 
{
   exclude 'META-INF/maven/com.squareup.okhttp/okhttp/pom.properties
   exclude 'META-INF/maven/com.squareup.okhttp/okhttp/pom.xml'
}

Please check for correct path "com.squareup.okhttp/okhttp/pom.properties" in your errorlog.
