React native how to fix INSTALL_FAILED_UPDATE_INCOMPATIBLE

When building an adnroid app, you might stumble upon this error: 

`Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE...`. Here's how to fix it:

That's because the app you're trying to test was already installed on the device and the signatures are different now, so it's complaining. The full error will look like something like this:

`Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.example signatures do not match the previously installed version; ignoring!`

You can see that the package ID is `com.example`, well, simply run this command:

`adb uninstall com.example`, it should say `Success` and you're good to go!

Thanks! Should be somewhere in the React Native docs.
