Android Capture Image From Camera And Upload To Firebase Github

Capturing images from the camera on an Android device is a common feature in many mobile applications. In this tutorial, we will teach you how to capture an image from the camera on an Android device and upload it to Firebase Github. Firebase is a mobile and web application development platform that provides various tools and services, including real-time database, authentication, storage, and hosting. Github is a web-based platform that hosts version control repositories using Git. We will use both Firebase and Github services to build our application. Let's get started!

Prerequisites

Before we start, make sure you have the following prerequisites:

Android Studio installed on your computer
A Firebase account
A Github account

Create a Firebase Project

The first step in building our application is to create a new Firebase project. Here are the steps to create a new Firebase project:

Go to the Firebase Console (https://console.firebase.google.com/).
Click on the "Add project" button.
Enter a name for your project and select your country/region.
Click on the "Create project" button.

Once your project is created, you will be redirected to the project dashboard. From here, you can access various Firebase services that we will be using in our application.

Add Firebase to your Android Project

The next step is to add Firebase to your Android project. Here are the steps to add Firebase to your Android project:

Open your Android Studio project.
Click on the "Tools" menu and select "Firebase".
Click on the "Assistant" tab.
Click on the "Authentication" option.
Click on the "Connect to Firebase" button.
Follow the prompts to link your project to Firebase.
Click on the "Add the Firebase Authentication SDK" button.

Once you have added Firebase to your Android project, you can use various Firebase services in your application, including authentication, database, storage, and hosting.

Capture an Image From Camera

The next step is to capture an image from the camera on an Android device. Here are the steps to capture an image from the camera:

Add camera permission to your AndroidManifest.xml file.
Create a new activity to capture the image.
Open the camera and capture the image.
Save the image to the device or upload it to Firebase Storage.

Here is a sample code on how to capture an image from the camera:

private void dispatchTakePictureIntent() {Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);if (takePictureIntent.resolveActivity(getPackageManager()) != null) {startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);}}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {Bundle extras = data.getExtras();Bitmap imageBitmap = (Bitmap) extras.get("data");mImageView.setImageBitmap(imageBitmap);}}

The above code will open the camera and capture an image. The captured image will be displayed in an ImageView.

Upload Image to Firebase Storage

The final step is to upload the captured image to Firebase Storage. Firebase Storage is a cloud storage solution provided by Firebase. Here are the steps to upload the image to Firebase Storage:

Add Firebase Storage dependency to your build.gradle file.
Initialize Firebase Storage in your activity.
Create a reference to the Firebase Storage location where you want to upload the image.
Convert the image to a byte array.
Upload the byte array to Firebase Storage.
Retrieve the download URL of the uploaded image.

Here is a sample code on how to upload an image to Firebase Storage:

mStorageRef = FirebaseStorage.getInstance().getReference();ByteArrayOutputStream baos = new ByteArrayOutputStream();imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);byte[] data = baos.toByteArray();UploadTask uploadTask = mStorageRef.child("images").child("image.jpg").putBytes(data);uploadTask.addOnFailureListener(new OnFailureListener() {@Overridepublic void onFailure(@NonNull Exception exception) {// Handle unsuccessful uploads}}).addOnSuccessListener(new OnSuccessListener() {@Overridepublic void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {// taskSnapshot.getMetadata() contains file metadata such as size, content-type, etc.// ...}});

The above code will upload the captured image to Firebase Storage. Once uploaded, you can retrieve the download URL of the image and use it in your application.

Conclusion

In this tutorial, we have learned how to capture an image from the camera on an Android device and upload it to Firebase Github. We have used Firebase Storage to store the captured image and Github to host our application's source code. With this knowledge, you can build your own mobile applications that capture images and store them in the cloud. Happy coding!
