Intent to Navigation Drawer Activity not working

I have been trying to add a Navigation Drawer Activity to my code, I followed an old tutorial that upon creation didn't create fragments, but I tried to make ti work none the less, I think I did everything right but when opening then emulator, the app doesn't take me to the activity but to the launcher one(?), is it the emulator or is it the code?
Navigation Drawer:
public class NavigationDrawerActivity extends AppCompatActivity {
private AppBarConfiguration mAppBarConfiguration;
FirebaseDatabase database;
DatabaseReference category;
TextView txtFullName;
RecyclerView recyclerView;
RecyclerView.LayoutManager layoutManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation_drawer);
Toolbar toolbar = findViewById(R.id.toolbar);
toolbar.setTitle("Options");
setSupportActionBar(toolbar);
//Init. Firebase
database = FirebaseDatabase.getInstance();
category = database.getReference("Category");
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_home, R.id.nav_gallery, R.id.nav_slideshow)
.setDrawerLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
//Set name for User
View HeaderView = navigationView.getHeaderView(0);
txtFullName = findViewById(R.id.txtFullName);
if (Common.currentUser != null) {
txtFullName.setText(Common.currentUser.getName());
finish();
} else if (Common.CurrentFirebaseUser != null) {
txtFullName.setText(Common.CurrentFirebaseUser.getDisplayName());
finish();
}
//Load Options
recyclerView = findViewById(R.id.recycler);
recyclerView.setHasFixedSize(true);
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
loadFilter();
}
private void loadFilter() {
FirebaseRecyclerAdapter<Category,FilterViewHolder> adapter = new FirebaseRecyclerAdapter<Category, FilterViewHolder>(Category.class, R.layout.filter_item, FilterViewHolder.class, category) {
#Override
protected void populateViewHolder(FilterViewHolder filterViewHolder, Category category, int i) {
FilterViewHolder.txtFilterName.setText(category.getName());
Picasso.with(getBaseContext()).load(category.getImage())
.into(filterViewHolder.imageView);
Category clickItem = category;
filterViewHolder.setItemClickListener(new ItemClickListener() {
#Override
public void onClick(View view, int position, boolean isLongClick) {
Toast.makeText(NavigationDrawerActivity.this, ""+ clickItem.getName(), Toast.LENGTH_SHORT).show();
}
});
}
};
recyclerView.setAdapter(adapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.navigation_drawer, menu);
return true;
}
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
}
SignIn leading to the Navigation Drawer (ignore the login logic):

I tried to see if the fragments created were the problem, if the NavigationDrawerActivity should use an other xml file or if I was missing some logic, but I still don't understand why it would take me to the Launcher Activity instead of the NavigationDrawer one, the SignIn logic does work with other activities other than the NavigationDrawer one

Unable to solve error - javax.mail.authenticationfailedexception: [EOF]

I have created an application where it scans bar codes and QR codes on the phone and send an email of the collected data to my personal email which is a gmail. However, recently it stopped sending emails and prompted me an error as shown below:

I have been told to change it from SMTP to SSL but I cant seem to fix the issue.

I have problem when i play video it's not working

Anyways Part of the tutorial makes use of a RecyclerView and I can't access it on my activity_main.xml file stating that v7 is an unresolved package. android.support.v7.widget.RecyclerView shows up with v7 onwards as red text. I know I can revert it back to older versions but I guess I am trying to make this work since moving forward its expected to know how to use androidx right?
I don't know how to add the RecyclerView to the project with my current project migrated to androidx.
What I've tried:

v7 RecyclerView is legacy now and you should use the androidx package instead.
to do this, add the androidx RecyclerView dependency to build.gradle(Module:app) like this
dependencies {
...
implementation "androidx.recyclerview:recyclerview:1.2.1"
...
}
and then change it's head name in xml layout to this :
<androidx.recyclerview.widget.RecyclerView
... />
and it will work as intended.
N.B : three dots (...) in my code means that I don't care the code written here and you should include your code instead.
for more information about how to deal with androidx RecyclerView check this Android Developers Tutorial

Call php script inside java activity after click

I am parsing a JSON title, URL etc. from a PHP script. I want to give a reward with PHP script after the user click my link. Reward code -
String awr = Config.Base_Url+"videos/award.php";
Now everything is working, there is just no reward, no call to my PHP script...
How do i need modify my script to get correct reward? My java activity -

How to start New Layout (activity) from ListView

When I click the ListView, I'd like to start a new Activity
Here is my MainActivity.java
package com.theheran.listviewicon;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
public class MainActivity extends Activity {
//Declarasi Array Menu dan gambar
ListView list;
String[] menu = {
"#The_Heran",
"www.theheran.com",
"Add",
"Delete",
"Next",
"Back",
"Find",
"Warning"
} ;
Integer[] imageId = {
R.drawable.ic_launcher,
R.drawable.signal,
R.drawable.add,
R.drawable.trash,
R.drawable.next,
R.drawable.back,
R.drawable.find,
R.drawable.warning
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CustomListView adapter = new
CustomListView(MainActivity.this, menu, imageId);
list=(ListView)findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
Toast.makeText(MainActivity.this, "You Clicked at " +menu[+ position], Toast.LENGTH_SHORT).show();
// HERE THE PROBLEM (Intent)
Intent intent = new CustomListView(MainActivity.this,);
startActivity(intent);
}
});
}
}
My CustomListView
package com.theheran.listviewicon;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class CustomListView extends ArrayAdapter<String> {
//Declarasi
private final Activity context;
private final String[] web;
private final Integer[] imageId;
public CustomListView(Activity context,String[] web, Integer[] imageId) {
super(context, R.layout.list_single_data, web);
this.context = context;
this.web = web;
this.imageId = imageId;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
//Load Custom Layout untuk list
View rowView= inflater.inflate(R.layout.list_single_data, null, true);
//Declarasi komponen
TextView txtTitle = (TextView) rowView.findViewById(R.id.txtList);
ImageView imageView = (ImageView) rowView.findViewById(R.id.imgIcon);
//Set Parameter Value
txtTitle.setText(web[position]);
imageView.setImageResource(imageId[position]);
return rowView;
}
}

// HERE THE PROBLEM (Intent)
Intent intent = new CustomListView(MainActivity.this,);
startActivity(intent);
Here you are trying to use a wrong structure.
Use this:
Intent intent = new Intent(MainActivity.this, NextActivity.class);
MainActivity.this.startActivity(intent );

Try this way ,
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(MainActivity.this, "You Clicked at " +position , Toast.LENGTH_SHORT).show();
Intent MoveToNext = new Intent(getApplicationContext(), Your_Next_Activity.class);
startActivity(MoveToNext);
}
});

This is how I have done it. You start a new activity using the startActivityForResult(intent, 2); Where you throw a intent and a number (number that you check for when you go back to the starting page).
private void registerButtonClickList() {
ListView list = (ListView) findViewById(R.id.listView);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(InThisClass.this, GoingToThisClass.class);
intent.putExtra("Position", position);
startActivityForResult(intent, 0);
}
});
}
Use this where in the same class as you started the other one form the list. This is needed since you are expecting a return when you start with startActivityForResult()
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0) {
if (resultCode == Activity.RESULT_OK) {
//See what u should do using the requestCode
//and check if it ended OK
}
if (resultCode == Activity.RESULT_CANCELED) {
//what you do when canceled
}
}
}
And in the activity that you started you need to end with this because you are expected to return something. This you do by using setResult().
Button btn = (Button) findViewById(R.id.btn);
btnCANCEL.setOnClickListener(new View.OnClickListener() {
#TargetApi(Build.VERSION_CODES.CUPCAKE)
#Override
public void onClick(View v) {
Intent intent = new Intent();
setResult(Activity.RESULT_OK, intent);
//intent.putExtra("something", something); if you need to send something back
finish();
}
});
Hope this helps!
