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

问题

I am a newbee in the Android development. 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. I understood its becuase I used vector images and android 4.1 is not compatible with it. To overcome this I set the code as mentioned below:

 // 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

Please help me in debugging this. I am kind of stuck and would need your help.

回答1:

You are using vector drawables. On Android 4.x and earlier, this is only supported if you:

use Android Support Libraries 23.x or later ✓
enable it in the gradle build file (vectorDrawables.useSupportLibrary = true) ✓
use srcCompat instead of src whenever you use ImageView

The last item is probably the problem that needs to be fixed.
