How to Upload a Video in Firebase Database using Android Studio?

Last Updated : 11 Jul, 2021

Firebase is a mobile and web application development platform. It provides services that a web application or mobile application might require. Firebase provides secure file uploads and downloads for the Firebase application. This article explains how to build an Android application with the ability to select a video from the mobile gallery and upload the video to Firebase Storage.

Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language. Or open an existing project in which you want to add authentication and add the firebase to that android application.

Step 2. Add these dependencies in the build.gradle (Module:app) file

implementation 'com.google.firebase:firebase-storage:19.1.0'
implementation 'com.google.firebase:firebase-database:20.0.0'

Step 3: Working with the activity_main.xml file

Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.

XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/uploadv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Upload Video" />

</LinearLayout>

Step 4: Working with the MainActivity.java file

Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

Java

import android.content.ContentResolver;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;

import com.google.firebase.storage.UploadTask;

import java.util.HashMap;

public class MainActivity extends AppCompatActivity {

    Button uploadv;
    ProgressDialog progressDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // initialise layout
        uploadv = findViewById(R.id.uploadv);
        uploadv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Code for showing progressDialog while uploading
                progressDialog = new ProgressDialog(MainActivity.this);
                choosevideo();
            }
        });
    }

    // choose a video from phone storage
    private void choosevideo() {
        Intent intent = new Intent();
        intent.setType("video/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(intent, 5);
    }

    Uri videouri;

    // startActivityForResult is used to receive the result, which is the selected video.
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 5 && resultCode == RESULT_OK && data != null && data.getData() != null) {
            videouri = data.getData();
            progressDialog.setTitle("Uploading...");
            progressDialog.show();
            uploadvideo();
        }
    }

    private String getfiletype(Uri videouri) {
        ContentResolver r = getContentResolver();
        // get the file type ,in this case its mp4
        MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
        return mimeTypeMap.getExtensionFromMimeType(r.getType(videouri));
    }

    private void uploadvideo() {
        if (videouri != null) {
            // save the selected video in Firebase storage
            final StorageReference reference = FirebaseStorage.getInstance().getReference("Files/" + System.currentTimeMillis() + "." + getfiletype(videouri));
            reference.putFile(videouri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    Task<Uri> uriTask = taskSnapshot.getStorage().getDownloadUrl();
                    while (!uriTask.isSuccessful()) ;
                    // get the link of video
                    String downloadUri = uriTask.getResult().toString();
                    DatabaseReference reference1 = FirebaseDatabase.getInstance().getReference("Video");
                    HashMap<String, String> map = new HashMap<>();
                    map.put("videolink", downloadUri);
                    reference1.child("" + System.currentTimeMillis()).setValue(map);
                    // Video uploaded successfully
                    // Dismiss dialog
                    progressDialog.dismiss();
                    Toast.makeText(MainActivity.this, "Video Uploaded!!", Toast.LENGTH_SHORT).show();
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    // Error, Image not uploaded
                    progressDialog.dismiss();
                    Toast.makeText(MainActivity.this, "Failed " + e.getMessage(), Toast.LENGTH_SHORT).show();
                }
            }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                // Progress Listener for loading
                // percentage on the dialog box
                @Override
                public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                    // show the progress bar
                    double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot.getTotalByteCount());
                    progressDialog.setMessage("Uploaded " + (int) progress + "%");
                }
            });
        }
    }
