Update Non market android application

Step 1: Create a Class: UpdateapplicationV


import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.AsyncTask;
import android.util.Log;
public class UpdateapplicationV extends AsyncTask<String,Void,Void>{
private Context context;
public void setContext(Context contextf){
    context = contextf;
}

@Override
protected Void doInBackground(String... arg0) {
      try {
            URL url = new URL(arg0[0]);
            HttpURLConnection c = (HttpURLConnection) url.openConnection();
            c.setRequestMethod("GET");
            c.setDoOutput(true);
            c.connect();

            String PATH = "/mnt/sdcard/Download/";
            File file = new File(PATH);
            file.mkdirs();
            File outputFile = new File(file, "update.apk");
            if(outputFile.exists()){
                outputFile.delete();
            }
            FileOutputStream fos = new FileOutputStream(outputFile);

            InputStream is = c.getInputStream();

            byte[] buffer = new byte[1024];
            int len1 = 0;
            while ((len1 = is.read(buffer)) != -1) {
                fos.write(buffer, 0, len1);
            }
            fos.close();
            is.close();

            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/Download/update.apk")), "application/vnd.android.package-archive");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
            context.startActivity(intent);


        } catch (Exception e) {
            Log.e("UpdateAPP", "Update error! " + e.getMessage());
        }
    return null;
}} 


Step 2: Add code in your main activity 

UpdateapplicationV atualizaApp = new UpdateapplicationV();
            atualizaApp.setContext(getApplicationContext());
            atualizaApp.execute("http://Your url/apkfile.apk");

       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
       WifiState = (TextView)findViewById(R.id.wifistate);
       Button OnWifi = (Button)findViewById(R.id.onwifi);
       Button OffWifi = (Button)findViewById(R.id.offwifi);
      
       this.registerReceiver(this.WifiStateChangedReceiver,

How to enable fast scrolling in Android

Fast Scrolling in Android happens when you have a lot of items in your screen and you need to scroll fast. When it is activated you well see an small box coming from the right of the screen and when you drag it up or down it goes really fast. You can see this in your contact list, email or any application that has a lot of data and is sorted alphabetically.

There are 2 ways to enable this functionality in your application:
By adding the property in your XML layout file:

    <ListView

        android:id="@id/android:list"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent" 

        android:fastScrollEnabled="true" />

or by adding it in your java code:

      getListView().setFastScrollEnabled(true);
