How to upload image on firebase without button android studio

How to upload the image without "upload" button and to use that new image automatically as default user picture? How can I implement this in my code.
mAuth = FirebaseAuth.getInstance();
circlePic = findViewById(R.id.circleImageView);
FirebaseUser user = mAuth.getCurrentUser();
if (user != null) {
Glide.with(this)
.load(user.getPhotoUrl())
.into(circlePic);
public void Profile(View view) {
Intent cpicview = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(cpicview, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageRIntent) {
super.onActivityResult(requestCode, resultCode, imageRIntent);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK)
mProfileUri = imageRIntent.getData();
Uri selectedImage = imageRIntent.getData();
this.circlePic.setImageURI(selectedImage);

first add click listener to your imageview that will open activity to choose an image
profileImage.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Profile Image"), REQUEST_CODE);
}
});
then implement onActivityResult that will be executed when image is selected
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == REQUEST_CODE) {
InputStream inputStream = context.getContentResolver().openInputStream(data.getData());
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
uploadImage(bitmap);
}
}
this is the method to upload Bitmap
private void uploadImage(Bitmap bitmap)
{
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReferenceFromUrl("Your url for storage");
StorageReference mountainImagesRef = storageRef.child("images/" + chat_id + Utils.getCurrentTimeStamp() + ".jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos);
byte[] data = baos.toByteArray();
UploadTask uploadTask = mountainImagesRef.putBytes(data);
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadUrl = taskSnapshot.getDownloadUrl();
Log.d(downloadUrl);
}
});
}
and don't forget to declare REQUEST_CODE in your class
public static final int REQUEST_CODE = 1;
and maybe you will need to add this line in your xml for your profile image view
android:clickable="true"

Firebase upload photo

I have a code for upload an image to Firebase Storage. The code was running well but when I updated Android Studio there is a problem with code. Can you please suggest how should I change the code?
private StorageReference mStorage;
private static final int GALLERY_INTENT = 2;
private ProgressDialog mProgressDialog;
private ImageView imageViewProfilePicturePreview;
...
#Override
protected void onCreate(Bundle savedInstanceState) {
...
mProgressDialog = new ProgressDialog(this);
mDatabase = FirebaseDatabase.getInstance().getReference();
mStorage = FirebaseStorage.getInstance().getReference();
imageViewProfilePicturePreview = (ImageView) findViewById(R.id.imageViewProfilePicturePreview);
}
...
#Override
public void onClick(View view) {
...
if (view == textViewUploadPhoto) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, GALLERY_INTENT);
}
}
...
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GALLERY_INTENT && resultCode == RESULT_OK) {
mProgressDialog.setMessage("Uploading...");
mProgressDialog.show();
StorageReference imageRef = mStorage.child(email);
StorageReference imageImagesRef = mStorage.child("photos/" + email);
imageRef.getName().equals(imageImagesRef.getName()); // true
imageRef.getPath().equals(imageImagesRef.getPath()); // false
Uri uri = data.getData();
imageViewProfilePicturePreview.setImageURI(uri);
imageViewProfilePicturePreview.setDrawingCacheEnabled(true);
imageViewProfilePicturePreview.buildDrawingCache();
Bitmap bitmap = imageViewProfilePicturePreview.getDrawingCache();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] data2 = baos.toByteArray();
UploadTask uploadTask = imageImagesRef.putBytes(data2);
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
Toast.makeText(getApplicationContext(), "Sorry, your image wasn't set, please try again",
Toast.LENGTH_LONG).show();
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Intent intent = new Intent(getApplicationContext(), MapsActivity.class);
startActivity(intent);
Uri downloadUrl = taskSnapshot.getDownloadUrl();
mProgressDialog.dismiss();
Picasso.with(getApplicationContext()).load(downloadUrl).fit().centerCrop().into(imageViewProfilePicturePreview);
Toast.makeText(getApplicationContext(), "Upload done",
Toast.LENGTH_SHORT).show();
}
});
}
}
Thanks for all help.

Firebase Storage, onSuccessListener not doing as intended

I've been trying to create an app which uses Firebase authentication, Firebase storage and Firebase database. Im trying to get the downloadURI from the successListener but it never reaches, and the toast never displays. However, in Firebase Storage it has successfully created a folder with profilepictures and uploaded the image. I dont see what im doing wrong, so any help is appreciated!
public class RegisterLastActivity extends AppCompatActivity {
private EditText displayName;
private Button cheersButton;
private ImageView profilePicture;
private Uri imageFile;
private boolean imageFileChosen = false;
private StorageReference mStorageRef;
private DatabaseReference mDatabase;
private static final int PICK_IMAGE_REQUEST = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register_last);
displayName = (EditText) findViewById(R.id.displayname);
cheersButton = (Button) findViewById(R.id.cheers_button);
profilePicture = (ImageView) findViewById(R.id.profile_picture);
mStorageRef = FirebaseStorage.getInstance().getReference();
mDatabase = FirebaseDatabase.getInstance().getReference();
cheersButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
sendToStorage(imageFile);
startActivity(new Intent(RegisterLastActivity.this, MainActivity.class));
finish();
}
});
}
public void imagePressed(View view) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST); }
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
setImageFile(uri);
imageFileChosen = true;
Log.d("OnActivityResult", "imageFileChosen " + String.valueOf(imageFileChosen));
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
//Log.d(TAG, String.valueOf(bitmap));
profilePicture.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
protected void sendToStorage(Uri uri){
if(imageFileChosen){
StorageReference storageReference = mStorageRef.child("Profilepictures").child(getCurrentToken());
storageReference.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
#SuppressWarnings("VisibleForTests") Uri downloadUri = taskSnapshot.getDownloadUrl();
Toast.makeText(RegisterLastActivity.this, "Kom inn til success!", Toast.LENGTH_SHORT).show();
}
});
}else{
Toast.makeText(this, "Choose an image!", Toast.LENGTH_SHORT).show();
}
}
protected String getCurrentToken(){
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if(user != null){
return user.getUid();
}
return null;
}
public void setImageFile(Uri imageFile) {
this.imageFile = imageFile;
}
}
This doesnt produce any error messages in Android Monitor. Look for sendToStorage(Uri uri) method, that's where i have the error. I had to include the #SuppressWarnings("VisibleForTests") because it gives me an annoying error without.

});
}
};
new Thread(runnable).start();
}
}
}
please help, everything look fine to me.

** This will not save the image in full resolution **
To save a picture in full resolution, research how to do that when you start the TakePictureIntent.
I had the same error and solved it by setting up my picture taking and uploading like this:
//takes the picture
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
startActivityForResult(takePictureIntent, 1);
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == Activity.RESULT_OK) {
//saves the pic locally
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] dataBAOS = baos.toByteArray();
/***************** UPLOADS THE PIC TO FIREBASE*****************/
// Points to the root reference
StorageReference storageRef = FirebaseStorage.getInstance().getReferenceFromUrl("your-root-storage-ref");
StorageReference imagesRef = storageRef.child("image");
UploadTask uploadTask = imagesRef.putBytes(dataBAOS);
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.
Uri downloadUrl = taskSnapshot.getDownloadUrl();
}
});
}
}
This way it will compress and save your image in your Firebase Storage with this file struct:
root -> image

You can pass the InputStream directly from the Uri to the putStream method. You may want to resize the image yourself before uploading it, which would require a bit more work, but this way uses very little memory on the client side.
if (requestCode == IMAGE_PICKER_SELECT && resultCode == Activity.RESULT_OK) {
Uri imageUri = data.getData();
try {
ContentResolver contentResolver = getActivity().getContentResolver();
StorageMetadata storageMetadata = new StorageMetadata.Builder()
.setContentType(contentResolver.getType(imageUri))
.build();
FirebaseStorage.getInstance().getReference()
.child("users")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
.child(UUID.randomUUID().toString())
.putStream(contentResolver.openInputStream(imageUri), storageMetadata)
.addOnSuccessListener(getActivity(), new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot task) {
Uri downloadUrl = task.getDownloadUrl();
Toast.makeText(getActivity(), R.string.image_successfully_uploaded, Toast.LENGTH_LONG).show();
}
})
.addOnFailureListener(getActivity(), new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(getActivity(), R.string.error_uploading_image, Toast.LENGTH_LONG).show();
}
});
} catch (IOException e) {
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
