Answer 1

If you added the latest Facebook SDK or using + for Facebook dependency, revert to a previous version

compile 'com.facebook.android:facebook-android-sdk:4.16.1'

Answer 2

Open your android SDK manager (from C:\Users\youruseraccount\AppData\Local\Android\sdk) and update following to latest versions in,

Tools section section

1. Android SDK Tool

2. Android SDK Platform-Tools

3. Android SDK Build tool

Android 7.1.1 (API 25) section

1. SDK Platform

Extras Section

1. Android Support Repository
2. Android Support Library

Then update your gradle file accordingly.

Answer 3

I had the same problem earlier today. Out of nowhere, I started having those weird error messages. Updating:

1. Android SDK Tool
2. Android SDK Platform-Tools
3. Android SDK Build tool
4. Android Support Repository

did the trick for me. Just go to Tools > Android > SDK Manager in your Android Studio then find and update them. Good luck!

Answer 4

Just updating the Android support repository version to 25 did my work. Thanks to all of you for the guidance!

Answer 5

Facebook updated their SDK to use the latest support libraries. You could replace

compile 'com.facebook.android:facebook-android-sdk:[4,5)'

with

compile 'com.facebook.android:facebook-android-sdk:4.16.1'

if you do not want to update your android sdk just yet.

Answer 6

If you try to remove facebook-sdk compile from dependencies will not show that error. So i think is facebook sdk error.

I was using 'com.facebook.android:facebook-android-sdk:[4,5)' but gives error, i tried this com.facebook.android:facebook-android-sdk:4.+ but is the same. But when i remove it app build successfully. Am i the only i came in this conclude and having the same problem ?
