You need also add: implementation 'com.android.support:support-v4:28.0.0' in your gradle file like this:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

and this is a full implementation:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'

you'd have to use api "com.android.support:appcompat-v7:27.1.1" -

or the later (future) api "androidx.appcompat:appcompat:1.0.2" from androidx.

using "release candidates" and "alpha versions" is discouraged, because these are not well tested.

just see the official documentation ...it recommends 27.1.1.

Many answers already on this one but I feel like noone explaines how to keep it up to date, just how to fix this specific version. So here it is

  • The com.android.support:appcompat version must match the compileSdkVersion
  • It is preferable to use stable versions if you release to production
  • Look on the android website to find the lastest stable version that correspond to your compile version (even is this link gets broken, the info will be available somewhere on the official website)

Example, as of today (end of january 2019), the lastest stable support library version is 28.0.0 (according to android website), so the correct implementation is

implementation 'com.android.support:appcompat-v7:28.0.0'

Replace 

implementation 'com.android.support:appcompat-v7:28.1.1

with 

implementation 'com.android.support:appcompat-v7:28.0.0-rc01'

Currently, the most recent available release for appCompat is 28.0.0-rc01, you are trying to pull an unavailable version of appcompat library.

I solved this by trial and error and using some of the answers above.

I changed the appcompat to a lower version "com.android.support:appcompat-v7:27.1.0" along with changing 

compileSdkVersion 27

and targetSdkVersion 27

I'm still getting warnings but Picasso should now run.

Please add these below dependencies to solve the issue, try it:

implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:support-v13:27.1.1'
implementation 'com.android.support:design:27.1.1'

also change the version of AppCompat as:

implementation 'com.android.support:appcompat-v7:27.1.1'

AppCompat Sometimes doesn't work alone. Adding these might solve your issue.

Root cause: The version 28.1.1 is not exist.

Solution: Use the latest stable version

implementation 'com.android.support:appcompat-v7:27.1.1'

or use latest unstable version

implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
