I've started to learn to make Android apps recently but I've faced a problem in launching Android Studio!
I downloaded android studio and also downloaded SDK tools from here ( I downloaded them separately ) and when I give SDK path to the Studio, it installs SDK successfully but when the project opens, it says that some Android SDK tools are missing!
Error :Gradle sync failed: Failed to find target with hash string 'android-26' in: E:\android-sdk
I'm confused because I can find no problem in my downloading and installing but there is an error!
What should I do?
