When executing react-native run-android I am getting an error that is mentioned in multiple questions in stack overflow. However, none of the proposed solutions works for me.

The error is:

`Failed to find target with hash string 'android-28' in: C:\Users\<username>\AppData\Local\Android\Sdk`

This is part of the log that seems related to the problem:

    * What went wrong:
    A problem occurred configuring project ':app'.
    > Failed to find target with hash string 'android-28' in: C:\Users\yossi\AppData\Local\Android\Sdk

I have the following defined as an env. variable:

    ANDROID_HOME=C:\Users\yossi\AppData\Local\Android\Sdk

I also tried to define it (following https://github.com/facebook/react-native/issues/8547#issuecomment-243929377) as:

    ANDROID_HOME=C:\\Users\\yossi\\AppData\\Local\\Android\\Sdk

and added another env. variable called `sdk-dir`, based on the same comment. Didn't help.

In this folder (C:\Users\yossi\AppData\Local\Android\Sdk) I have both `platform-tools` and `platforms`, and under `platforms` I have `android-28`.

I didn't find a solution, so I downgraded to android studio 2.3 and the problem is gone (downloaded it from https://android-studio.en.uptodown.com/windows/download/1500423. I see now that it is also available in https://developer.android.com/studio/archive).

This question So far unresolved!

Still, unresolved. @rahamin1 I have android studio 3.6.1, still facing the issue, as you mentioned it's working in 2.3. so is there any alternate solution or should i also downgrade the android studio?

I'm using MacOS.

ERROR: Failed to find target with hash string 'android-28' in: C:\android-ndk-r21

Still this problem today as well.

Any fix for this bug???

I need ndk r21 for Unreal Engine 4.25 - it is mandatory to have one for 4.25.
