Building an APK in React Native

Creating a keystore for your APK is easier than you might think! First, head over to the Android app subdirectory in your project where you’ll want to save your keystore.
Next up, you’ll use the key tool command to specify PKCs 12 as the store type, and remember to set a catchy name and alias for your keystore.
Make sure to configure the key algorithm to RSA with a solid key size of 2048 bits and give it a validity of 6 years .
It’s a good idea to personalize that keystore name and alias for better organization later on.
Don’t forget to whip up a strong password via a password generator to keep things secure; just enter and confirm it when asked.
Lastly, when prompted, enter your name or organization’s name for clear identification of the keystore owner.
Once everything looks good, hit Y to confirm and ensure your settings are saved properly, keeping your keystore safe and sound!.

Alright, let’s dive into how to configure your keystore and whip up that APK! Start by opening the Gradle Properties file in your Android folder; this is where you’ll be configuring your project settings.
You’ll want to set your keystore name to “Device Mart Keystore” and the alias to “Device Mart”—just make sure your passwords match, or you might run into some pesky build errors.
Once that’s done, save your changes and open up the build file in your app directory to tweak define your build configurations.
Remember to switch the signing config from “debug” to “release” for a proper build.
If you’re looking to generate your APK easily, the package JSON has a helpful command script ready to go.
Just hit up the terminal and run yan apk, and voilà—you can even install it directly on a connected device!.

So, when you finish building your Android app, the magic happens in the APK release folder, where your APK gets generated.
This file can then be easily installed on any Android device you want to test it on, whether it’s a mobile phone or an embedded device.
There’s a great video that walks you through making a Distributable Android Package Kit.
Plus, look out for the next video, which dives into using an Android embedded board for kiosk setups.
It’ll cover how to keep your screen bright, hide those pesky status and navigation bars, and ensure your program kicks off automatically when the device starts up..
