Behold, the iCloud Cometh

A number of stories today on the new iCloud service to be offered by Apple. The announcement is planned for next Monday's WWDC keynote along with details on OS X Lion and iOS 5.



Initial indications are that iCloud provides online music storage like the Amazon and Google cloud offerings of the last few weeks. The main difference is that, Apple will be able to read your library and make the music you have purchased available without requiring an upload. Services like this were provided in the 1990s, but all were sued into bankruptcy by the music labels.



I don't see an online library and player as that big a deal. We already have an infrastructure built around the iPhone and iPod. So being able to play music from the net seems a bit redundant and not all that useful.



What we really need is the ability to sync all our devices from a central location. I want to put my music files and movies in one place in cloud. Then, use that master copy to keep all my devices synced. Hopefully that is what will be announced. But somehow I doubt the entertainment industry is ready to go that far.

Play audio using MediaPlayer

To play audio in Android, we can use MediaPlayer. Base on the audio file from last exercise "Start audio recording with intent of MediaStore.Audio.Media.RECORD_SOUND_ACTION", modify to add a Play button to start audio playback using MediaPlayer. Additionally, we have to implement MediaPlayer.OnCompletionListener() method to handle the OnCompletion event.

package com.exercise.AndroidIntentAudioRecording;

import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;

public class AndroidIntentAudioRecording extends Activity {

final static int RQS_RECORDING = 1;

Uri savedUri;

Button buttonRecord, buttonPlay;

 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
     buttonRecord = (Button)findViewById(R.id.record);
     buttonPlay = (Button)findViewById(R.id.play);
     buttonPlay.setEnabled(false);
  
     buttonRecord.setOnClickListener(new Button.OnClickListener(){

 @Override
 public void onClick(View arg0) {
  // TODO Auto-generated method stub
  Intent intent =
   new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
  startActivityForResult(intent, RQS_RECORDING);
 }});
  
     buttonPlay.setOnClickListener(new Button.OnClickListener(){

 @Override
 public void onClick(View arg0) {
  // TODO Auto-generated method stub
  MediaPlayer mediaPlayer = MediaPlayer.create(AndroidIntentAudioRecording.this, savedUri);
  mediaPlayer.setOnCompletionListener(completionListener);
  mediaPlayer.start();
  buttonRecord.setEnabled(false);
  buttonPlay.setEnabled(false);
 }});
 }

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if(requestCode == RQS_RECORDING){
 if(resultCode == RESULT_OK){
  savedUri = data.getData();
  buttonPlay.setEnabled(true);
  Toast.makeText(AndroidIntentAudioRecording.this,

    Toast.LENGTH_LONG).show();
 }else{
  buttonPlay.setEnabled(false);
  Toast.makeText(AndroidIntentAudioRecording.this,
    "User Cancelled!",
    Toast.LENGTH_LONG).show();
 }

}
}

MediaPlayer.OnCompletionListener completionListener
= new MediaPlayer.OnCompletionListener(){

Asus UX21 11.6-inch Light and Thin Laptop Review and Price

Modeling after the Apple MacBook Air is a design feat few have taken on, with the Samsung Series 9 being one of the most recent examples. Now throw Asus into the mix. At Computex 2011, the Asus UX21 takes on more MacBook Air characteristics than any other ultraportable I've seen thus far, and it packs quite a performance punch for a little guy.

The term "unibody" is a design term coined by Apple and one that Asus had no trouble using when it lifted the wraps off of the UX21. Indeed, its unibody frame is entirely engorged in aluminum metal, a much more polished version than the one found on the MacBook Air. The metal is hardened so that any worries about its durability should be put to the rest.Like the Air 11-inch, the UX21 has a sloping design, which starts at 7mm in the back and tapers to 3mm once you reach the front bezel. It tips the scales at 2.2 pounds, which is exactly what the Air 11-inch weighs. The 11.6-inch widescreen and 1,366x768 resolution are also consistent with the Air. It uses a similar Chiclet-style keyboard and glass touchpad, though I found the two mouse buttons a bit too resistant for my tastes.

There are some subtle differences with regards to their feature sets. One of the UX21's two USB ports houses USB 3.0 technology (the Air 11-inch has two USB 2.0 ports). Instead of mini-DisplayPort, the UX21 has a mini-HDMI port. They both don't have built-in SD card readers, which would have been impressive had Asus pulled one off. Storage comes in SSD varieties: 64GB or 128GB. Asus also claims that with these drives, the UX21 can resume from sleep in two seconds.

The UX21 that was on display ran on an Intel Core i5-2557M (1.7GHz) processor, which means it's a standard voltage variant and more powerful than the low-voltage ones found in the Samsung Series 9 and MacBook Airs. Asus also claims that it can scale as high as a Core i7, though it didn't say which one. With a standard volt processor, battery life becomes a concern. And given its size, a more powerful CPU, and the fact that the battery is completely sealed in means that we're looking at no more than five hours.There's no word on pricing yet, but when I asked one of the PR reps if the Asus UX21 will be less expensive than the MacBook Air 11-inch, the answer was a resounding yes.[www.pcmag.com]

New Sony Vaio S Series Laptops review

A new 13.3-inch ultraportable laptop from Sony has recently entered the market. Called the VAIO S Series, the system sports a 13.3-inch 1366 x 768 or 1600 x 900 LED-backlight display, an Intel Core i5-2410M/2520M or Core i7-2620M processor, an AMD Radeon HD 6470M 512MB or AMD Radeon HD6630M 1GB graphics card, up to 8GB DDR3 RAM, up to 640GB HDD or 512GB/1TB SSD, an HD webcam a DVD or Blu-ray drive, an SD card slot, WiFi, Bluetooth, a USB 3.0 port, an HDMI port and runs on Windows 7 OS.

The latest Sony Vaio S Series laptop is boasting a battery life of 15 hours but that is of course only when you partner it with a sheet battery - and with SSD configurations. The new SA Series comes encased in a magnesium-and-aluminum alloy and comes in burnished brown, jet black or platinum silver. Measuring only 24mm in height and weighing 1.7kg, the SA Series boasts some impressive specs. The SA model comes with Intel�s second generation Core i7 processor and combined with a AMD Radeon HD 6630 1GB Hybrid Graphics card (select models), it should provide enough grunt on the move for most users. Also included is a 13.3in display with a resolution of 1600 x 900, a 500GB HDD, fingerprint reader and Blu-ray drive. There is also the option to upgrade to a dual channel SSD, which as we said will improve battery time further. Starting at $1,350 and going up to $1,650 for an SSD-touting model, the SA Series ain�t cheap.Also launched today is the Vaio SB series which comes at a lower price but as you�d expect also with less impressive specs. For $999 you�ll get 512MB of video RAM (compared to 1GB with the SA), a 1366 x 768 resolution display, DVD player and a Core i5 Sandy Bridge processor � though it is possible to upgrade to the more powerful i7 processor. And just in case you don�t like the classy-looking burnished brown or platinum silver of the SA series, then you can get the SB series in pink or navy."Users these days want a laptop that will last for hours without charging, is small and light enough to carry around with you but doesn't sacrifice any of the performance and power that you'd find in a full-sized PC," said Mike Lucas, senior vice president of Networked Technology and Services Division at Sony Electronics. "You can fly nonstop from Los Angeles to Tokyo or attend a full day of classes on just one charge with this S Series laptop when combined with the optional sheet battery."[laptops.techfresh.net]
Price starts at $999.99.

BlueStacks: runs Android OS and apps on Windows PCs

BlueStacks runs Android OS and apps on Windows PCs with instant switch between Android and Windows - no reboot is required. End consumers can now enjoy their favorite Android apps on Windows PCs. Android apps can appear either as icons on the Windows desktop, or within a full-blown Android environment.

BlueStacks helps PC manufacturers to ride the Android momentum by enabling Android apps on x86-based tablets, netbooks, notebooks, convertibles and AiO Windows PCs. With the new hybrid convertible form factors, BlueStacks completely eliminates the need to carry two devices. The end consumer benefits from getting both Android and Windows at the price of a single PC.

Get the list of paired Bluetooth devices

With bluetoothAdapter, the list of paired BluetoothDevice can be retrieved by calling getBondedDevices() function.



Implement a new activity ListPairedDevicesActivity.java

package com.exercise.AndroidBluetooth;

import java.util.Set;

import android.app.ListActivity;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothClass;
import android.bluetooth.BluetoothDevice;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class ListPairedDevicesActivity extends ListActivity {
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);

  ArrayAdapter<String> btArrayAdapter 
    = new ArrayAdapter<String>(this,
             android.R.layout.simple_list_item_1);
  
  BluetoothAdapter bluetoothAdapter 
   = BluetoothAdapter.getDefaultAdapter();
  Set<BluetoothDevice> pairedDevices 
   = bluetoothAdapter.getBondedDevices();

  if (pairedDevices.size() > 0) {
      for (BluetoothDevice device : pairedDevices) {
       String deviceBTName = device.getName();
       String deviceBTMajorClass 
        = getBTMajorDeviceClass(device
          .getBluetoothClass()
          .getMajorDeviceClass());
       btArrayAdapter.add(deviceBTName + "\n" 
         + deviceBTMajorClass);
      }
  }
  setListAdapter(btArrayAdapter);
  
 }
 
 private String getBTMajorDeviceClass(int major){
  switch(major){ 
  case BluetoothClass.Device.Major.AUDIO_VIDEO:
   return "AUDIO_VIDEO";
  case BluetoothClass.Device.Major.COMPUTER:
   return "COMPUTER";
  case BluetoothClass.Device.Major.HEALTH:
   return "HEALTH";
  case BluetoothClass.Device.Major.IMAGING:
   return "IMAGING"; 
  case BluetoothClass.Device.Major.MISC:
   return "MISC";
  case BluetoothClass.Device.Major.NETWORKING:
   return "NETWORKING"; 
  case BluetoothClass.Device.Major.PERIPHERAL:
   return "PERIPHERAL";
  case BluetoothClass.Device.Major.PHONE:
   return "PHONE";
  case BluetoothClass.Device.Major.TOY:
   return "TOY";
  case BluetoothClass.Device.Major.UNCATEGORIZED:
   return "UNCATEGORIZED";
  case BluetoothClass.Device.Major.WEARABLE:
   return "AUDIO_VIDEO";
  default: return "unknown!";
  }
 }

 @Override
 protected void onListItemClick(ListView l, View v, int position, long id) {
  // TODO Auto-generated method stub
  super.onListItemClick(l, v, position, id);
  
     Intent intent = new Intent();
     setResult(RESULT_OK, intent);
     finish();
 }
 
}

Modify main.xml to add a button to start ListPairedDevicesActivity.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<TextView 
    android:id="@+id/bluetoothstate" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
<Button
    android:id="@+id/listpaireddevices" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:text="List Paired Devices" 
    android:enabled="false"
    /> 
<TextView
    android:id="@+id/bluetoothstate" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
</LinearLayout>

Modify AndroidBluetooth.java

package com.exercise.AndroidBluetooth;

import android.app.Activity;
import android.bluetooth.BluetoothAdapter;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class AndroidBluetooth extends Activity {
 
 private static final int REQUEST_ENABLE_BT = 1;
 private static final int REQUEST_PAIRED_DEVICE = 2;
 
    /** Called when the activity is first created. */
 Button btnListPairedDevices;
 TextView stateBluetooth;
 BluetoothAdapter bluetoothAdapter;
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        btnListPairedDevices = (Button)findViewById(R.id.listpaireddevices);
        
        stateBluetooth = (TextView)findViewById(R.id.bluetoothstate);
        bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        
        CheckBlueToothState();
        
        btnListPairedDevices.setOnClickListener(btnListPairedDevicesOnClickListener);
    }
    
    private void CheckBlueToothState(){
     if (bluetoothAdapter == null){
         stateBluetooth.setText("Bluetooth NOT support");
        }else{
         if (bluetoothAdapter.isEnabled()){
          if(bluetoothAdapter.isDiscovering()){
           stateBluetooth.setText("Bluetooth is currently in device discovery process.");
          }else{
           stateBluetooth.setText("Bluetooth is Enabled.");
           btnListPairedDevices.setEnabled(true);
          }
         }else{
          stateBluetooth.setText("Bluetooth is NOT Enabled!");
          Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
             startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
         }
        }
    }
    
    private Button.OnClickListener btnListPairedDevicesOnClickListener
    = new Button.OnClickListener(){

  @Override
  public void onClick(View arg0) {
   // TODO Auto-generated method stub
   Intent intent = new Intent();
   intent.setClass(AndroidBluetooth.this, ListPairedDevicesActivity.class);
   startActivityForResult(intent, REQUEST_PAIRED_DEVICE); 
  }};

 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  // TODO Auto-generated method stub
  if(requestCode == REQUEST_ENABLE_BT){
   CheckBlueToothState();
  }if (requestCode == REQUEST_PAIRED_DEVICE){
   if(resultCode == RESULT_OK){

   }
  } 
 }   
}

Modify AndroidManifest.xml to add activity ListPairedDevicesActivity, also include permission of "android.permission.BLUETOOTH".

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.exercise.AndroidBluetooth"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="7" />
    <uses-permission android:name="android.permission.BLUETOOTH"></uses-permission>

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".AndroidBluetooth"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
  <activity android:name=".ListPairedDevicesActivity" 
      android:label="AndroidBluetooth: List of Paired Devices"/>
    </application>
</manifest>
