        reference.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override

                // Toast.makeText(getApplicationContext(),"File Uploaded",Toast.LENGTH_LONG).show();
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(getApplicationContext(),e.getMessage(),Toast.LENGTH_LONG).show();
            }
        }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                double totalProgress=(100*taskSnapshot.getBytesTransferred())/taskSnapshot.getTotalByteCount();
                // Toast.makeText(getApplicationContext(),"File uploaded"+(int)totalProgress,Toast.LENGTH_LONG).show();
            }
        });
    }
}

In Firebase storage, there is one folder called "customers" where I want to store the selected image. When I try to upload the image, it is storing it as a different folder, not the folder which is already created. Here, "customers" is the already created folder.

Answer 1

Try to get file from this file, it could be because of incorrect reference to your folder. Also show code where is your getReference() method is called or it is better how you set reference to your FirebaseStorage.

Answer 2

public void upload(String imageName) {
    if(imageUri!=null) {
        StorageReference reference=storageReference.child("customers).child(imageName);
        reference.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                // Toast.makeText(getApplicationContext(),"File Uploaded",Toast.LENGTH_LONG).show();
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(getApplicationContext(),e.getMessage(),Toast.LENGTH_LONG).show();
            }
        }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                double totalProgress=(100*taskSnapshot.getBytesTransferred())/taskSnapshot.getTotalByteCount();
                // Toast.makeText(getApplicationContext(),"File uploaded"+(int)totalProgress,Toast.LENGTH_LONG).show();
            }
        });
    }
}

In order to retrieve the image name use:-

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        Uri selectedImageUri = data.getData( );
        String picturePath = getPath( getActivity( ).getApplicationContext( ), selectedImageUri );
        Log.d("Picture Path", picturePath);
        upload(picturePath);

    }
}

public static String getPath( Context context, Uri uri ) {
    String result = null;
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver( ).query( uri, proj, null, null, null );
    if(cursor != null){
        if ( cursor.moveToFirst( ) ) {
            int column_index = cursor.getColumnIndexOrThrow( proj[0] );
            result = cursor.getString( column_index );
        }
        cursor.close( );
    }
    if(result == null) {
        result = "Not found";
    }
    return result;
}
