I'm trying to add the `react-native-firestack` package to my app. But it keeps giving the following error :

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment.
Go to https://facebook.github.io/react-native/docs/getting-started.html
and check the Android tab for setup instructions.

I tried to add some packages to `exclude group` in several packages. But none worked. Here's the `./gradlew clean :app:dependencies` result: <https://gist.github.com/THPubs/8fe8b4b9c80e3c6cd49541d66887c742>

Tried to follow other similar stack overflow question but looks like this package has a lot of dependencies. I was unable to find the conflict.

My `build.gradle` dependencies:

```
dependencies {
    compile(project(":react-native-firestack"))
    compile project(':react-native-onesignal')
    compile project(':react-native-fbsdk')
    compile project(':react-native-share')
    compile project(':react-native-video')
    compile project(':react-native-uuid-generator')
    compile project(':react-native-udp')

    compile project(':react-native-contacts')
    compile project(':react-native-linear-gradient')
    compile project(':react-native-vector-icons')
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"  // From node_modules
    compile project(':react-native-image-picker')
    compile(project(":react-native-google-signin")){

    }
