I have tried to install Android SDK Platform 23, but still nothing ... Has anyone ever experienced this? Thanks in advance.

Create a file named local.properties and go to the android folder of your ReactNative project.

The file extension should be .properties . Put the following configuration within the file: 

sdk.dir=C\:\Users\MyName\AppData\Local\Android\Sdk

Generally, Sdk is installed on this path, make sure it is correct before doing so.

If you are using Windows , use \ to enter the path.

If you are using Android Studio or have already used it, you can go to the folder of a created project, copy local.properties and paste it into the Android folder of your project > ReactNative .

If you come across the error below

  

You have not accepted the license agreements of the following SDK components: [Android SDK Platform 23, Android SDK Build-Tools 23.0.1]

You can do the following: Go to the Sdk directory, the same one that was defined in local.properties and open the tools\bin folder, directory, open CMD and do the following: 

cd C:\Users\MyName\AppData\Local\Android\Sdk\tools\bin

C:\Users\MyName\AppData\Local\Android\Sdk\tools\bin>sdkmanager --licenses

It will look something like this:

  

x of and SDK package licenses not accepted   Review licenses that have not been accepted? (y / n)

Type Y and press enter . Proceed by typing Y and pressing enter to accept licenses .
