Android Build fails when the latest Android SDK Tools 25.3.1 version is used



How to reproduce:
1. Update Android SDK Tools to 25.3.1
- In Mac open Android Studio -> Check for updates and update Android Studio version (might be not necessary)
- In Android Studio -> Preferences -> Appearance & Behavior -> System Settings -> Android SDK -> SDK Tools
2. Create a new Unity project
3. Build and run on Android device
Result: Build fails "CommandInvokationFailure: Unable to list target platforms. Please make sure the android sdk path is correct. See the Console for more details. ..."

Reproducible: 5.5.2p2, 5.6.0b11, 2017.1.0a3

Note: I haven't been able to reproduce this issue on Windows machine. As after update via Android Studio, SDK Manager still doesn't see SDK Tools 25.3.1 version and uses 25.2.5

Workaround for the customers.

1) just open
2) scroll down to the bottom of that page
3) go to downloads
4) scroll down to the bottom of that page
5) find Windows "" download and unzip it
5) find MacOSX "" download and unzip it.
6) In the SDK path replace the tools folder.

Unity versions: 5.4.5p2, 5.5.3p3, 5.6.0p3, 2017.1.0b3
SDK Tools have to be updated to 26.x.x

    seems in my case its something to do with a legacy scene i started on 5.6 that includes old vuforia elements (pre-unity 2017.2 )

    a blank scene with a cube will build. so Im going to have to start again from scratch adding things one at a time, nooooooooo!

    Ive come across this problem too,

    Ive tried many variables
    unity 5.6 or 2017.2
    a variety of SDK versions (mainly 26)
    gradle or default builder
    JDK 1.8 or 9
    using that tool_r25 hack or not.

    currently not able to build with
    unity 2017.2
    and that tools_r25 hack

    any help would be much apprecaited

    Finally got it working! Unity 2017.1.2p1, Java SDK 8 (Kit 8u151), Android SDK platform 23 (6.0), replaced the tools folder in the SDK folder with Android SDK tools_r25.2.3.

    I'm new to android development and I can't seem to build an apk.
    I've followed multiple tutorials and it still won't work.
    From what I have read here you need to use different versions of 'SDK' and 'JDK'
    Could someone link me to the exact versions I need to download.

    This is what worked for me....

    1.) Install JDK jdk1.8.0_131 and set it as the JDK Path in Unity
    2.) Delete android sdk "tools" folder : [Your Android SDK root]/tools -> tools
    Download SDK Tools:
    Extract the tools folder in that archive to Android SDK root
    Build your project

    This is still a problem and I can not find a copy of the needed file for the work around. Very frustrating!
