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).

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

Crash after isCurrentInputMethodAsSamsungKeyboard on a Samsung tablet

I'm seeing a few crashes from a Samsung Galaxy Tab S tablet. All I have is the stacktrace, which doesn't help much:
Fatal Exception: java.lang.SecurityException: get package info: Neither user 1110217 nor current process has android.permission.INTERACT_ACROSS_USERS.

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1194)
It's obvious that my app doesn't care about INTERACT_ACROSS_USERS. The system ends up requesting that exception after isCurrentInputMethodAsSamsungKeyboard, which I've never seen before.
Any clues?

Android 5.0.1 VerifyError?

I have just updated the OS on my phone to Android 5.0.1. Since this update, an app that I am working on, that is working perfectly fine on my other devices, is now throwing an error in 5.0.1 only. I have no idea what this error means, and it isn't pointing me to a suspicious line of code like it often does.
Has anyone seen this or know what it is about with the new 5.0.1?

For anyone else having any issues since the Android update, I have found and resolved my issue.
The allowed maximum method size has obviously changed. Some of my methods were quite large and complex, and this new limit was obviously exceeded.
This fix was to break larger sections of code into smaller sections.
Hope this helps someone.
