java.lang.IllegalArgumentException: uri cannot be null

I am getting and error while uploading an image and storing data to Firebase. I am using Bitmap to display the images. After submitting the data the app crashes and returns to the previous Activity. Also, when I pick an image from the device it is not displaying in the ImageView.
My error:

How to make messages appear on different sides?

I make a chat app using a video tutorial, but this tutorial does not show how to make messages from different people appear on different sides. The sender and receiver see all messages on the left. Could you please give some advices on this? Thanks in advance.
Now it looks like this

Try adding layout_gravity attribute in your BubbleTextView when you need this like this:
android:layout_gravity="right"

Every user will have a unique email - Let say here in the example - d#mail.ru is your email. You need to add user logic to dynamically check to decide whether you want a bubble test layout to be LEFT or RIGHT.
Update the message bubble layout.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/parentLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:id="#+id/message_user"
android:textStyle="normal|bold"
/>

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:id="#+id/message_time"

app:angle="10dp"
app:arrowWidth="8dp"
app:arrowHeight="10dp"
app:arrowPosition="10dp"
app:bubbleColor="#03dac5"
/>
</RelativeLayout>
Adapter code:- you can update as you need either LEFT or RIGHT.
adapter = new FirebaseListAdapter<Message>(options){
#Override
protected void populateView(View v, Message model, int position) {
TextView mess_user, mess_time;
BubbleTextView mess_text;
RelativeLayout Layout = v.findViewById(R.id.parentlayout);
mess_user = v.findViewById(R.id.message_user);
mess_time = v.findViewById(R.id.message_time);
mess_text = v.findViewById(R.id.message_text);
mess_user.setText(model.getUserName());
mess_text.setText(model.getTextMessage());
mess_time.setText(DateFormat.format("dd-MM-yyyy HH:mm:ss", model.getMessageTime()));
if(!model.getUserName().equals("d#mail.ru")) {
mess_text.setGravity(Gravity.LEFT)
} else {
mess_text.setGravity(Gravity.RIGHT)
}
}

Retrofit error in Android

I am trying to create a login page. Onclick of the button, I am calling a method to verify the login credentials if already present in the backend django server. I am able to fetch the values of the username and password. The problem that I am currently facing is, if I give the login credentials already present in the backend server, the application works fine. But if I give login credentials which are not in the backend database, the application crashes. Kindly help
