Issue
One of the Activities on an app i am building is a profile update activity with an option to upload display picture. I am trying to implement upload picture option using Picasso through the following code. So far i am unable to retrieve the picture from the phone with a constant null for Uri and failure to display picture in the ImageView due to that.

private void UploadPic(){

// save the image with uid of the currently logged user
StorageReference fileReference = storageReference.child(authProfile.getCurrentUser().getUid() + " . " + getFileExtension(uriImage));
//Upload image to storage
fileReference.putFile(uriImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {

progressBar.setVisibility(View.GONE);
Toast.makeText(UploadProfilePicture.this, "Picture Upload is successful", Toast.LENGTH_SHORT).show();

startActivity(intent);
finish();
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Toast.makeText(UploadProfilePicture.this, e.getMessage(), Toast.LENGTH_SHORT).show();
Toast.makeText(UploadProfilePicture.this, "Something went wrong!" ,Toast.LENGTH_SHORT).show();
}
});
} else {
progressBar.setVisibility(View.GONE);
Toast.makeText(UploadProfilePicture.this, "No file was selected", Toast.LENGTH_SHORT).show();
}
}
//Obtaining File Extension of the image
private String getFileExtension(Uri uri){
ContentResolver CR = getContentResolver();
MimeTypeMap mime = MimeTypeMap.getSingleton();
return mime.getExtensionFromMimeType(CR.getType(uri));
}
No errors or noticeable Logcat line related. Simply it would exit the Picture picker and would not display the image in the imageView. Of course it would Toast the message of " Uri is null" since it is following the if statement included to follow the process steps to see the missing task !
Is my code of choosing and uploading picture is wrong or something is missing >
Solution
I guess it was a syntax error in the if statement within the onActivityResult
it was:
if (resultCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null){
Correction :
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null){
At the moment the issue is resolved and image could be chosen and displayed within the app.
Facing a new issue with this code but this should be for another question if needed
E/StorageException: StorageException has occurred.
User does not have permission to access this object.
Code: -13021 HttpResult: 403
