butterknife 10.1.0 < 14

[sensay-nelson]

im getting the following error when trying to build this:

Manifest merger failed : uses-sdk:minSdkVersion 10 cannot be smaller than version 14 declared in library [com.jakewharton:butterknife:10.1.0] /Users/nelson/.android/build-cache/f263ed3f2d86b8bbc41249e7b8e0f9c2c2d4fe9d/output/AndroidManifest.xml
	Suggestion: use tools:overrideLibrary="butterknife" to force usage

I tried following this solution here:
https://stackoverflow.com/questions/27095077/how-do-i-use-toolsoverridelibrary-in-a-build-gradle-file

And kept adding tools:xx,yy,zz until it came down to this issue:

AGPBI: {"kind":"error","text":"No resource identifier found for attribute \u0027appComponentFactory\u0027 in package \u0027android\u0027","sources":[{"file":"/Users/nelson/Code/sensay/aws-device-farm-sample-app-for-android/app/build/intermediates/manifests/full/debug/AndroidManifest.xml","position":{"startLine":30}}],"original":"","tool":"AAPT"}

:app:processDebugResources FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:processDebugResources'.

then i gave up. i'm new to android dev. any suggestions?
