minSdkVersion 16 cannot be smaller than version 19 declared in library

Hello guys i have a problem which i cannot run the application, it says "minSdkVersion 16 cannot be smaller than version 19 declared in library"
I tried to change the number from AndroidManifest.xml in "\transformed\jetified-play-services-maps-18.0.2" and save it using wordpad but it keeps saying the same error

> Task :app:processDebugMainManifest FAILED
C:\Users\Gian\IdeaProjects\Mapy\app\src\main\AndroidManifest.xml Error:
    uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [com.google.android.gms:play-services-base:18.0.1] C:\Users\Gian\.gradle\caches\transforms-3\08cedd8d440dee889f2cf950b3489944\transformed\jetified-play-services-base-18.0.1\AndroidManifest.xml as the library might be using APIs not available in 16
    Suggestion: use a compatible library with a minSdk of at most 16,
        or increase this project's minSdk version to at least 19,
        or use tools:overrideLibrary="com.google.android.gms.base" to force usage (may lead to runtime failures)

See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.

so, how do i fix that? and what have i done wrong?


Thanks!!
