所以我们最近将buildToolsVersion更新为26.0.2现在我们的代码在我尝试创建CircularProgressButton时使用的CircularProgressButton库中崩溃（see library我知道我们使用不受支持的库得到了我们应得的）。
堆栈跟踪表明它是由InflationException“二进制XML文件行＃0”引起的。但是当我在调试时跟踪它时，我可以看到TypedArray.getDimension（）调用抛出了UnsupportedOperationExcetion，这是崩溃的真正根本原因。 getDimension（）方法中发生的事情是我们期望TypedValue是TYPE_DIMENSION但它是TYPE_STRING。有没有人知道我在哪里可以看到属性或TypedValue是如何设置的？
完整堆栈跟踪：

答案 0 :(得分：0)
在项目的build.gradle中，将gradle版本配置为2.3.3，对我有用。
buildscript {
// other codes
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
}
}
