应用程序在 android 5.1 和 6.1 中运行良好,但在 4.10(API 16) 中崩溃

App works well in android 5.1 and 6.1 but crashes in 4.10(API 16)

我是 Android 开发的新手。我能够使此应用程序在 Android 5.1 中运行,但是当我尝试在 Android 4.1 中部署此应用程序时,它曾经在主 activity 本身中崩溃。我理解它是因为我使用了矢量图像并且 android 4.1 与它不兼容。为了克服这个问题,我设置了如下代码:

 // Gradle Plugin 2.0+  
 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
    }  
 }  
You’ll note this new attribute only exists in the version 2.0 of the Gradle Plugin. If you are using Gradle 1.5 you’ll instead use
 // Gradle Plugin 1.5  
 android {  
   defaultConfig {  
     generatedDensities = []  
  }  

  // This is handled for you by the 2.0+ Gradle Plugin  
  aaptOptions {  
    additionalParameters "--no-version-vectors"  
  }  
 }

我现在收到这个错误

请帮我调试一下。我有点卡住了,需要你的帮助。

您正在使用矢量绘图。在 Android 4.x 及更早版本中,仅当您满足以下条件时才支持此功能:

  • 使用 Android 支持库 23.x 或更高版本 ✓
  • 在 gradle 构建文件中启用它(vectorDrawables.useSupportLibrary = true)✓
  • 每当您使用 ImageView
  • 时,请使用 srcCompat 而不是 src

最后一项可能是需要修复的问题。
