How to retrieve image from firestore in a clickable span widget?

This is my code to retrieve:
this.view.setOnClickListener(new View.OnClickListener() {

Open video playing in ExoPlayer into external player intent

So I have an app which plays media in ExoPlayer2 but now I wanted to add a button which can open the same video in an external player.
I am actually not getting what to add in intent so help is required.
Here's the open in external button option I'm trying to add:
imgPlayer.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(), "video/*");
startActivity(Intent.createChooser(intent, "Complete action using"));
}
});
Now the issue is, idk what to add in Uri.parse(), I want the currently playing video to be played in an external player.
Thanks in advance.

Pass the url of your video, use it like this
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("http://Your URL"), "video/*");
startActivity(Intent.createChooser(intent, "Complete action using"));
For pausing your Exoplayer
exoplayer.playWhenReady(false);

How do I get a gridview class to call itself on click, then on another grid item click, reference another activity?

Another class calls the GridView class below that is populated with images from a parse server, if a user clicks on a grid item, it starts the same GridView class with different bundled strings so it can pull from a different parse database class. Now at this point, when a user clicks an GridView item (from the 2nd gridview that was set up), I want it to start a different activity class.
I tried doing an if/else if statement in the onItemClick that takes the "PARSE_CLASS" bundled string but I can't seem to get that to work. I'm relatively new to android programming so I don't know the best way to do this.
public class DisplayGrid extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
GridView gridView = null;
List<ParseObject> obj;
ProgressDialog loadProgress;
GridViewAdapter adapter;
Bundle extras = new Bundle();
GridViewAdapter itemGridAdapter;
private List<ImageList> imageArrayList = null;
private List<String> categoryNameArrayList = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ws_display_grid);
imageArrayList = new ArrayList<ImageList>();
categoryNameArrayList = new ArrayList<String>();
gridView = (GridView) findViewById(R.id.gridView);
itemGridAdapter = new GridViewAdapter(DisplayGrid.this, imageArrayList);
gridView.setAdapter(itemGridAdapter);
new RemoteDataTask().execute();
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
Intent i = getIntent();
Bundle itemExtras = i.getExtras();
final String activeSupplier = itemExtras.getString("SUPPLIER");
String parseClass = extras.getString("PARSE_CLASS");
#Override
public void onItemClick(AdapterView<?> arg0, View v, int position,
long arg3) {
Intent t = new Intent(getApplicationContext(), DisplayGrid.class);
extras.putString("SUPPLIER", activeSupplier);
extras.putString("PARSE_CLASS", "Items");
t.putExtras(extras);
startActivity(t);
}
});

ParseUser.logOut();
Intent i = new Intent(getApplicationContext(), MainActivity.class);
startActivity(i);
return true;
}
return (super.onOptionsItemSelected(item));
}
//end onOptionsItemSelected
}
This is what I tried. When I tried this, the second GridView wouldn't load. So I'm guessing I'm unable to retrieve the "PARSE_CLASS" bundled string the second time around.
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
Intent i = getIntent();
Bundle itemExtras = i.getExtras();
final String activeSupplier = itemExtras.getString("SUPPLIER");
String parseClass = extras.getString("PARSE_CLASS");
#Override
public void onItemClick(AdapterView<?> arg0, View v, int position,
long arg3) {
if (parseClass == "Categories") {
Intent t = new Intent(getApplicationContext(), DisplayGrid.class);
extras.putString("SUPPLIER", activeSupplier);
extras.putString("PARSE_CLASS", "Items");
t.putExtras(extras);
startActivity(t);
} else if(parseClass == "Items"){
Intent t = new Intent(getApplicationContext(), ItemDisplay.class);
//extras.putString("SUPPLIER", activeSupplier);
//extras.putString("PARSE_CLASS", "Items");
//t.putExtras(extras);
startActivity(t);
}
}
});
ANSWER
Someone on reddit's learn programming was nice enough to point out that I had an issue with string comparisons. had to use
if(parseClass.equals("Categories")){}
instead of
if(parseClass == "Categories"){}
I feel like an idiot, hopefully someone else benefits from this long disastrous effort.
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
Intent t = getIntent();
Bundle itemExtras = t.getExtras();
String activeSupplier = itemExtras.getString("SUPPLIER");
String parseClass = itemExtras.getString("PARSE_CLASS");
#Override
public void onItemClick(AdapterView<?> arg0, View v, int position,
long arg3) {
Log.i("AppInfo", parseClass);
if (parseClass.equals("Categories")) {
Log.i("AppInfo", parseClass);
Intent t = new Intent(getApplicationContext(), DisplayGrid.class);
String categoryName = categoryNameArrayList.get(position);
itemExtras.putString("SUPPLIER", activeSupplier);
itemExtras.putString("PARSE_CLASS", "Items");
itemExtras.putString("CATEGORY_NAME", categoryName);
t.putExtras(itemExtras);
startActivity(t);
} else if (parseClass.equals("Items")) {
Intent t = new Intent(getApplicationContext(), ItemDisplay.class);
//extras.putString("SUPPLIER", activeSupplier);
//extras.putString("PARSE_CLASS", "Items");
//t.putExtras(extras);
startActivity(t);
