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
[英]App works well in android 5.1 and 6.1 but crashes in 4.10(API 16)
问题描述
I am a newbee in the Android development. 
我是Android开发中的新手。 I am able to make this app work in Android 5.1 and but however when I tried to deploy this app in Android 4.1 it used to crash in the main activity itself. 我可以使该应用程序在Android 5.1中运行，但是当我尝试在Android 4.1中部署该应用程序时，它通常会在主要活动本身中崩溃。 I understood its becuase I used vector images and android 4.1 is not compatible with it. 我理解它是因为我使用了矢量图像，而android 4.1与它不兼容。 To overcome this I set the code as mentioned below: 为了克服这个问题，我将代码设置如下：
// 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"
}
}
I am getting this error now 我现在收到此错误

You are using vector drawables. 您正在使用矢量可绘制对象。 On Android 4.x and earlier, this is only supported if you: 在Android 4.x和更早版本上，只有在以下情况下才支持此功能：
- use Android Support Libraries 23.x or later ✓ 使用Android支持库23.x或更高版本✓
- enable it in the gradle build file (vectorDrawables.useSupportLibrary = true) ✓ 在gradle构建文件中启用它（vectorDrawables.useSupportLibrary = true）✓
- use
srcCompatinstead ofsrcwhenever you useImageView每当使用ImageView时，请使用srcCompat而不是src
The last item is probably the problem that needs to be fixed. 最后一项可能是需要解决的问题。
