Android Studio build tools not found error

Question

Everything works as expected when creating a new project in android studio but when an already existing project is imported, error

"No installed build tools found. Please install version 19.0.1 or higher"

is shown. I have set the environment variables correctly. What could be wrong?

Check if the gradle options in setting is not selected to offline — aman5319, Jul 13 '18 at 09:55
Add a screenshot of your android studio window where it shows the error. — Einzig7, Jul 13 '18 at 09:55

You have two options:

Either install the required buildToolVersion. (In your case 19.0.1).

You can just press on button Install. Which appear with this error.
Or if you don't want to collect bunch of buildToolVersion. Then use one already existing in your sdk.

In this case you will follow these steps.

(1) First find existing buildToolVersion. Either find in your old project app level build.gradle or you can see that in sdkFolder>build-tools. In my case it is E:\Khemraj\AndroidDND\Sdk\build-tools

(2) Then replace buildToolVersion in app level build.gradle with already installed build-Tool.

(3) You have to reopen that project. (Because just sync does not work in this case for now (Possibly a bug of Android Studio))

Things to be considered

Offline mode should be disabled in case of installing new build-tool. (File>Setting>Search for offline). Disable Offline mode.
Make sure to reopen project if you change buildToolVersion.

I have a total of 9 build tools version above 19.0.1 already installed. I changed the root build.gradle to one of those versions, closed and opened the project. Still not working ;( – Phoenix Dev Jul 13 '18 at 10:10
Change 19.0.1 with one you have. Then reopen project. I am sure it will work, It is a common problem that every android developer face daily. – Khemraj Sharma Jul 13 '18 at 10:11
Now the final solution is update all the things to latest. – Khemraj Sharma Jul 13 '18 at 11:45
Inside app level build.gradle> update buildToolVersion, compileSdkVersion, all android:support versions. – Khemraj Sharma Jul 13 '18 at 11:46
In your project level build.gradle> update `com.android.tools.build:gradle` version. – Khemraj Sharma Jul 13 '18 at 11:46
In your `gradle.wrapper.properties` update gradle version distributionUrl. – Khemraj Sharma Jul 13 '18 at 11:47
Then you will not have any issue. But you can face some deprecated method in your project. – Khemraj Sharma Jul 13 '18 at 11:48
