Unity Error : Error building Player

Question

I am new in Unity and created my first Unity game for Android. When I try to build the .apk file, it shows me this error:

Error building Player: CommandInvokationFailure: Unable to list target platforms. Please make sure the android sdk path is correct. See the Console for more details. C:/Program Files/Java/jdk-9\bin\java.exe -Xmx2048M -Dcom.android.sdkmanager.toolsdir="C:\Users\PC\AppData\Local\Android\Sdk\tools" -Dfile.encoding=UTF8 -jar "C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\sdktools.jar" -

External tools Android

sdk : C:\Users\PC\AppData\Local\Android\Sdk

jdk : C:/Program Files/Java/jdk-9

Edit :

After downloading the android sdk tools_r25.2.3 and replacing the old tools folder inside Android SDK folder i have those errors :

first error :

I had the same problem so right now I'm using Unity v2017.1.1f1 and I fixed this by downloading the android sdk tools_r25.2.3 and replacing the old tools folder inside Android SDK folder (note: don't remove the old tools folder of Android sdk).
