android - 找不到vectorDrawbles

Question

我在android studio中创建了一个项目，但没有在其中添加代码。但是，当我尝试将其安装在手机软糖(4.2.2)版本上时。它返回“膨胀时异常”。
我收到这个错误

我试图在Android默认配置上添加“vectorDrawables.useSupportLibrary = true”，但仍无法正常工作。还将这段代码放在build.gradle上。 “generatedDensities = []”和“aaptOptions {AdditionalParameters“--no-version-vectors”}“。我收到此错误“错误:(13，0)没有这样的属性:类com.android.build.gradle.internal.dsl.ProductFlavor_Decorated的generateDensities”

Answer 1

I'm tried to add "vectorDrawables.useSupportLibrary = true"

为了使用它，您需要至少安装android gradle插件的版本2。目前，您正在使用1.3。当涉及 compileSdkVersion， buildToolsVersions和 support library时，您还应该避免混合使用版本。
