I was getting the same error (not sure if it was related to react-native-image-picker) but running cd android && ./gradlew clean fixed the issue for me.

I can reproduce, but I have no idea how to fix. Everything online indicates it's an issue with the android support library being included twice, but the only dependency that my library declares is for react-native. If anyone knows how to fix this, please send a pull request.

But it happens only if I install this package

I realize that...there is an issue with this package...I don't know how to fix it....

I've made it out, i tried to change the build.gradle as the other packages and it works

dependencies {
   classpath 'com.android.tools.build:gradle:1.1.3' => 1.3.1
}
defaultConfig {
  targetSdkVersion 22 => 23
}

@nihgwu Can you submit a pull request?

marcshilling on 23 Jun 2016

OK, and thanks for your work, this package is awesome
actually i made several changes, i'll find which one is the key point and then send a PR

nihgwu on 23 Jun 2016

I'm still getting this error. I was checking 0.19.6 and updating targetSdkVersion to 23 didn't help.
Went all the way back to 0.19.3 and it seems to be working.

@3vilguy have you tried to clean the build folders first? i've just add the dependencies section i didn't mention before, please remove the build folders both in the package and in the android folder, ( actually i also remove the .gradle folder for clean up)
one of my friend has solved the issue by update this packge

nihgwu on 24 Jun 2016

@nihgwu yeah I did remove almost anything from android folder which wasn't in original template. In fact I even tried doing:

react-native init AwesomeProject
cd AwesomeProject

npm install react-native-image-picker@latest --save
rnpm link react-native-image-picker

react-native run-android

And this is blowing up. So pretty much brand new project, nothing added yet, not builded yet...

Any other ideas?
