ERROR: Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 15 declared in library [androidmads.library.qrgenearator:QRGenearator:1.0.3] C:\Users\***\.gradle\caches\transforms-2\files-2.1\319b03b5fc5e9f0cda1a11565e242d4f\AndroidManifest.xml as the library might be using APIs not available in 14
	Suggestion: use a compatible library with a minSdk of at most 14,
		or increase this project's minSdk version to at least 15,
		or use tools:overrideLibrary="androidmads.library.qrgenearator" to force usage (may lead to runtime failures)

Můžete mi poradit jak na to kde je chyba?díky
