void uploadCompImage(){
    if (compliantImageUri != null) {
        StorageReference fileReference = mStorageRef.child(type).child(victimNameid.getText().toString()+"."+getFileExtension(compliantImageUri));
        fileReference.putFile(compliantImageUri)
                .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override

                        Toast.makeText(NewCompliant.this,"UPLOAD SUCCESSFUL",Toast.LENGTH_SHORT).show();
                    }
                })

        fileReference.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
            @Override

}

private void imgSearch(){

    imgRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {

            imageUrl = uri.toString();
            uploadCompData(imageUrl);
        }
    });
}

fileReference.putFile(compliantImageUri) is asynchronous the image will take some time to upload to that storage reference but fileReference.getDownloadUrl() will execute immediately after that line so you are immediately trying to access the download url of the image that is not uploaded yet that is why you are getting the the error , the image is uploaded when the

public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    Toast.makeText(NewCompliant.this,"UPLOAD SUCCESSFUL",Toast.LENGTH_SHORT).show();
                }

is executed , so access the download url in that method or anytime after this method is returned.

HAVE A GOOD DAY
