Getting SHA1 Fingerprint for Google API Console

Here is an Example of Getting SHA1 Fingerprint for Google API Console. As we all know, To use any Google API in Android we need to generate an API Key from Google API Console. This same API key can be used for accessing multiple APIs under the same project but to generate an API key we need SHA1 fingerprint of our Keystore.

Keystore is basically a place where the private keys for your app are kept. In simple words its a certificate generated by the user or a program, used for signing an Android  app.

Type of Keystores in Android

In Android there are two types of keystores:

  1. Debug Keystore

    Debug Keystore has generated automatically when the Android SDK is installed or run for the first time.

  2. Release Keystore

    Release Keystore has to be generated manually by the user for each application before release. As it requires private information such as name, password etc.

We will see how to generate both API key but first of all the question is why we need two Keystores?

As we all know SHA1 is the unique signature that depends upon the Keystore and Debug Keystore is unique for each system and it is automatically maintained by the Android SDK. So according to that if we sign a Release APK with the debug Keystore we have to update the same application with the same Keystore in future which is easy if you are working on the same machine for the lifetime but it is not practically possible. In this scenario, we will get stuck if we have to change the machine so to remove this problem we generate a Release Keystore (.jks) for each App which is transportable and we can update our application from the other machine too by using this Release Keystore.

Obtaining SHA1 Fingerprint from Android Keystore

Debug Keystore

There are two ways to get the Debug Keystore SHA1 which are using the CLI or by using Android Studio. Let’s see both ways:

Using CLI

Windows:
1. Open a terminal window.
2. Change the directory to the JDK bin directory. The path of the JDK depends upon the operating system you are using.

3. Now we have to run the following command using the keytool.exe file in JDK/bin


Ubuntu/Mac:
1. Open a terminal window.
2. Now run the following command

Using Android Studio

Release Keystore

To get the Release key CLI is the only best option we found till now.
Windows:
1. Open a terminal window.
2. Change the directory to the JDK bin directory. The path of the JDK depends upon the operating system you are using.

3. Now we have to run the following command using the keytool.exe file in JDK/bin

Ubuntu/Mac:
1. Open a terminal window.
2. Now run the following command

Example

It will prompt for a password.
Enter the password, you will get the SHA1 and MD5 fingerprint.

We hope this post will help you to get SHA1 Fingerprint for Google API Console. Please check out our other posts to learn React Native.

Example of YouTube Video Integration in React Native

Here is an Example of YouTube Video Integration in React Native. To integrate the YouTube video in our example we will use a library called react-native-youtube. Which provides a YouTube component which is very easy to use.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run
npm install -g react-native-cli
Run the following commands to create a new React Native project
react-native init ProjectName
This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use YouTube we need to install react-native-youtube package. To install this

Open the terminal and jump into your project

Run the following command

This command will copy all the dependencies into your node_module directory, You can find the directory in node_modulethe directory named react-native-youtube.

Linking of Library

To use react-native-youtube library we have to link some dependencies in Android and IOS project files. In order to link the library, you have to run following command

You can see the result like this

You can see the following changes in your android project. If you are unable to find the changes then please do those changes as they are must for this example.

Go to the YoutubeExample> android > app > build.gradle.
Scroll down and you can see the following dependency and if not please add this.

Open YoutubeExample> android > settings.gradle and you can see the following lines and if not please add this.

 

Open YoutubeExample> android > app > src > main > java > com > youtubeexample> MainApplication.java  and you can see the following lines in imports if not then please add

Scroll down and you can see the following line in getPackages after new MainReactPackage() if not then please add a comma(,) and add

 

Here we have done with our installation of the library. If you are still facing the trouble please comment below so that we can help you out from the problem.

Generate the API Key

To use Youtube in your Application we have to get Youtube API key from the Google Developer console. For that, open Developer console and log in from your Google account.

If you have already created any project you can use that or you can create a new one like this

After creating the project you can see all of your created project a drop down in the top left corner. Now select the project from the dropdown and goto to the credential section.

You can find the create credential option there.

Hit on the create credential button and it will create an API key to the user in your YouTube Application

Before we add this API key in our project you have to enable the API Library/ Feature which you want to use in your project. For that, you can search for the Youtube and you will find the Youtube related API Library. We will enable YouTube Data API. Click on YouTube Data API and you will found the enable button to enable the YouTube Data API.

Now after enabling the API key, we have to add this API key in our project’s App.js file. Just replace YOUR_API_KEY everywhere with your generated API key.

You can download the source code from Github

OR

Open App.js in any code editor and replace the code with the following code

App.js

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).

This is how you can integrate Youtube video in your React Native Application. If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned!

Hope you liked it. 🙂
