How to Install Android SDK properly in ubuntu 12.04 amd64

Android SDK in ubuntu 12.04 amd64

Android SDK is not working properly in ubuntu 12.04 amd64 , because ubuntu 12.04 64-bit dose not   have  ia32-libs package. So it gives adb error on Eclipse like

In this tutorial you will learn how to use AsyncTask in your application. This AsyncTask class perform background operations and update the results on the UI

AsyncTask has three generic type

• Params, the type of the parameters sent to the task upon execution.
• Progress, the type of the progress units published during the background computation.
• Result, the type of the result of the background computation

Private class ShowDialogAsyncTask extends 
        AsyncTask<Params, Progress, Result>{....}

AsyncTask goes through 4 steps

• onPreExecute(),invoked on the UI thread immediately after the task is executed.
•  doInBackground(Paaram ...),invoked on the background thread immediately after onPreExecute() finishes executing.
• onProgressUpdate(Progress...) invoked on the UI thread after a call to publishProgress(Progress...).
•  onPostExecute(Result), invoked on the UI thread after the background computation finishes.

How to Check Android Network / Internet Connectivity Status

It is not complex to Check Android Network / Internet Connectivity Status, bellow DetectConnection class
will help you to check Android Network / Internet Connectivity Status. Here I am going to load Android Wireless & Network Setting if device is not connected to any Network.

• Create an Android project called CheckConnection , visit my previous post  First Android Application in Eclipse Hello world Android Example

CheckConnectionActivity Activity will load Wireless & Network Setting if your Android device is not connected to the Network.

package com.jsupport;

import android.os.Bundle;
import android.provider.Settings;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import android.app.Activity;
import android.content.Intent;

public class CheckConnectionActivity extends Activity {

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.check_connection);

  Button check_connection = (Button) findViewById(R.id.btn_checkConnection);

  check_connection.setOnClickListener(new View.OnClickListener() {

   @Override
   public void onClick(View v) {
    if (DetectConnection
      .checkInternetConnection(CheckConnectionActivity.this)) {
     Toast.makeText(CheckConnectionActivity.this,
       "You have Internet Connection", Toast.LENGTH_LONG)
       .show();
    } else {
     Toast.makeText(CheckConnectionActivity.this,
       "You Do not have Internet Connection",
       Toast.LENGTH_LONG).show();

     CheckConnectionActivity.this.startActivity(new Intent(
       Settings.ACTION_WIRELESS_SETTINGS));
    }
   }
  });
 }
}

Create DetectConnection class

Context.getSystemService(Context.CONNECTIVITY_SERVICE)

which will gives the Network information, network availability and the connectivity status of the device

package com.jsupport;

package com.jsupport;

import android.content.Context;
import android.net.ConnectivityManager;

public class DetectConnection {

 public static boolean checkInternetConnection(Context context) {
