问题描述

I am trying to integrate Google Signin in my Android App. I am facing issue with building apk when I include Google Services Dependencies. Below are my gradle files and error log. The google services lib is also prompting me to use gradle-wrapper 2.10 and not 2.8

推荐答案

Shahar给出了正确答案，只是我想补充一点是 -

Shahar has given right answer, only point I would like to add in is-

I在我的项目中有上百张图片，并且检查每张图片都是不可能的，因此我所做的是使用一种工具将它们全部转换为PNG格式。我是MAC用户，所以我使用了预览应用程序。我发现其中一个图像保存为PNG，但不是PNG文件。

I had hundred+ images in my project and checking every image was not possible, so what I did is used a tool to convert all of them in PNG at a time. I am MAC user so I used Preview App. I found one of the image was saved as PNG but not png file.
