I had the same problem with my linux laptop. I ran this inside my app root folder and worked:

chmod 755 android/gradlew

You have to give permission on the android/gradlew.

I found the answer on this github issue

And you must also do this:

3. Configure the ANDROID_HOME environment variable
   The React Native tools require some environment variables to be set up in order to build apps with native code.
   Add the following lines to your $HOME/.bash_profile config file:
   export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

   .bash_profile is specific to bash. If you're using another shell, you will need to edit the appropriate shell-specific config file.
