Is there a problem with my configuration or is something missing while processing Android build?

I also had same issue and solved that problem now.
In my case, empty, or null value is "current_key" value in google-services.jsonso I fill the value (web API key) found in the Firebase console

It's hard to tell for sure without more info on exactly what your app is doing, but this error could be caused by calling PlaceBuffer.get() with an out-of-range index (either < 0 or >= size).

and I can't seem to find anyone with this error. I've followed https://github.com/googlecast/CastHelloText-android/ to the point. I will post the full activity here if it's wanted.

I've found answer on google issue tracking system on https://issuetracker.google.com/issues/37129745
In short, update v7 supprt library to 25.1.1

Well,when I searched for answers,the responses were not useful...
And if you have some wonderful open source project to recommend ,hope you can tell me.Thx.
Sorry for my poor english...

You need to update your google play service of device.
You can see this Bug report which already has been addressed
and possibility you will have to update your gcm dependency then appropriate modifications of code will also required mean the deprecated methods will be needed to replaced with new one in the project for e.g GoogleApiAvailability to register token etc so also make sure you are using the latest gcm dependency in your project

ProGuard causing Jackson error, "Conflicting property name definitions"

I am using the Nest Android SDK and am getting close to releasing my application. I have found that it is not possible to use Proguard with the Nest SDK as it stands today. Once a user is authenticated, the data that comes back causes the crash below.
How can I get passed this, and still keep ProGuard enabled? I created an issue on the github page but I assume it will not be a high priority by Nest.
