Hello
i am in windows 8.1 unity 2017.2.1, trying to make an android game and when i try to make a build a message tell me sdk tool is outdated 0.0.0 <23.0.0 i try all the method tool v 25.25 but nothing has worked anyone can help me please.

That's a really outdated version... Jokes aside, this is a common issue with android SDK, start by looking at this thread, and in your google search ommit the version numbers, just look for outdated sdk tools. https://stackoverflow.com/questions/43049883/android-sdk-tools-older-version-with-working-android-tool

I know this is an old post but I have recently encountered this problem and have tried many solutions including the ones above.

Surprisingly, running Unity as Administrator solved it for me. Such a simple solution.

I have found the solution download the tool 25.2.5 and open the cmd at bin folder of the tools write in the cmd sdkmanager “platform-tools” press enter and wait when it’s done write sdkmanager “platforms;android-25” wait, after write sdkmanager “build-tool;25.2.5” in unity preference the sdk path is were you have the tools exemple: desktop\sdk25.2.5 or you can follow this tutorial of french game developer here:Unity 2017 installation de la SDK Android et de la JDK Java - YouTube
Download the sdk tools 25.2.5 here:http://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip

PS:sorry for my bad English.

Hello there,

I followed the solutions suggested by @Paraneuf and after doing so I got another error messages saying:

SDK Tools Versions 25.2.5 < 26.1.1

So then I opened Android Studio Settings and checked the default Android SDK Tools versions available and realized that the 25.2.5 version wasn’t downloaded yet (previous error message was: Required API Level 26 so I downloaded through that version)

SDK Manager 25.2.5

And then I got the error “failed to sign APK” again… so it was wasted time.

I know i'm about a year late but the "unsigned APK error" just means that you didnt probably sign the game. to do that just go to "player settings" > "publishing settings" and create a new key
