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.app.ProgressDialog; import android.content.ContentResolver; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.view.View; import android.webkit.MimeTypeMap; import android.widget.Button; import android.widget.Toast; import androidx.annotation.NonNull; import androidx.annotation.Nullable; import androidx.appcompat.app.AppCompatActivity; import com.google.android.gms.tasks.OnFailureListener; import com.google.android.gms.tasks.OnSuccessListener; import com.google.android.gms.tasks.Task; import com.google.firebase.database.DatabaseReference; import com.google.firebase.database.FirebaseDatabase; import com.google.firebase.storage.FirebaseStorage; import com.google.firebase.storage.OnProgressListener; import com.google.firebase.storage.StorageReference; 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 + "%"); } }); } } } Output:
