Change ImageView after choosing photo from Gallery - android-studio

Question

I am trying to change my imageview when its on click and then choose image from gallery then change it. But I don't think its working since when I tried running my project, it just crashes out of the app.
Navigation Drawer
ActivityResult
ActivityResultLauncher<String> mGetContent = registerForActivityResult(
new ActivityResultContracts.GetContent(),
new ActivityResultCallback<Uri>() {
#Override
public void onActivityResult(Uri uri) {
// Handle the returned Uri
}
});
ImageView
profileImage = (ImageView) findViewById(R.id.profilepic);
profileImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mGetContent.launch("image/*");
}
});
p.s. The ImageView is inside my navigation drawer. what I wanted to do is that whenever I click or press the ImageView which is the Hamburger Icon, it will redirect to gallery to choose image and then change it once the user chose one.
