I'm currently working on enhancing the user experience for the <snipped> app, and I've run into a bit of a roadblock. I'm trying to optimize the game lobby to ensure smooth navigation and quick loading times, especially as our user base continues to grow. However, I'm finding that even with various optimizations in place, there's still a noticeable delay when fetching and displaying the available game rooms, particularly during peak usage hours. I've tried implementing caching strategies and minimizing network requests, but the issue persists. Does anyone have suggestions or best practices for optimizing the lobby functionality in real-time multiplayer games like ours, particularly in terms of reducing latency and improving overall performance?
How to Optimize RecyclerView performance by implementing the ViewHolder
When working with RecyclerView, always utilize the ViewHolder pattern to improve performance by minimizing the number of findViewById() calls.
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
public static class ViewHolder extends RecyclerView.ViewHolder {
TextView textView;
public ViewHolder(View itemView) {
super(itemView);
textView = itemView.findViewById(R.id.textView);
}
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.textView.setText("Item " + position);
}
@Override
public int getItemCount() {
return 100; // Example size, use your actual data size here
}
}
By caching references to views in the ViewHolder, you avoid repeatedly calling findViewById() in onBindViewHolder(), resulting in smoother scrolling and improved efficiency.
Context: The ViewHolder pattern is crucial in Android development, especially when dealing with RecyclerViews. It's included here because optimizing RecyclerView performance is a common concern for Android developers. Without ViewHolder, each call to findViewById() in onBindViewHolder() can lead to performance issues, especially with large datasets. Implementing this pattern significantly enhances app responsiveness and user experience.

Refresh existing expired notification tokens
Hi Everyone ,
I'm in a bit of a pickle, hopefully someone can provide some guidance.
I have stale Firebase notification tokens in a database for an existing Xamarin application, initially (years back) the application never contained logic to refresh notification tokens.
With the most recent update to the application a background job was implemented with the intention of refreshing tokens, the problem is refreshing existing stale tokens, it doesn't seem that the job runs automatically after the application update is installed (I know this may seem dumb to the more experienced dev, please excuse me).
I've made use of Shiny.Jobs
to implement the background job.
I'm currently using Xamarin version number 4.8.0.1451

Will iPhone 15 bring new updates?
It has to be said that Apple in recent years has not had any particularly eye-catching upgrades. Even, some features that users like very much have been removed, such as fingerprint unlocking. I'm using iPhone 13 now, if I wear makeup sometimes, iPhone 13 can't recognize my face. Once, I failed to unlock many times with "iphone unavailable". Fortunately, I solved it with TunesKit iPhone Unlocker. I heard that the iPhone 15 will bring fingerprint unlocking back. Just look forward to it.

hi guyz,
What are the common problems encountered in mobile application development?
Battery Full / Low Indicator app
Hi, I am a beginner. I am trying to get a audio notification when the Android battery is full and low.
I understand the logic. As in, check battery status, then if battery_full run Android Media Player. I am trying to use it for my home needs. This is the MainActivity.java I have
package me.adminweb.batterydost;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.BatteryManager;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Are we charging / charged?
int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||
status == BatteryManager.BATTERY_STATUS_FULL;
// How are we charging?
int chargePlug = batteryStatus.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;
if(status == BatteryManager.BATTERY_STATUS_FULL){
//Play sound using Android MediaPlayer
MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.batteryfull);
mediaPlayer.start(); // no need to call prepare(); create() does that for you
}
Looks like I am missing a few things. I know @Dani through another forum. So thought of seeking help here. Would be nice if you can help me build this app. Thanks.
