Alex eReader

The Alex eReader is an e-book reader created by Spring Design. As with the Barnes & Noble Nook, the Alex features two screens. The upper is a 6-inch monochrome electronic ink screen and the lower is a 3.5 inch HVGA (480×320) touch screen color LCD. The device has Wi-Fi and mobile network connectivity and Internet browsing. The device runs on Android version 1.5. International release was expected during the first week of March 2010. Device shipment began April 14, 2010. Retail sales were discontinued in 2011. The device allows downloading content from web sites such as Google Books, Epub Books, Gutenberg, Web Books, Feed Books, Smash words, and others.

The content is stored on a removable microSD card. Users can also copy content to SD with PC or desktop computers.

The Alex e-reader combines two displays, a larger E Ink display mainly for reading, and a smaller color LCD touchscreen for browsing. Comparing the Alex with the nook e-reader, the smaller LCD screen is used for more than navigation. One can view content on either screen and use a button to change the display back and forth between the E Ink screen and color screen. The color screen is used to annotate text with the text on the EPD screen highlighted in gray whenever there is a highlight, text or voice annotation, or hyperlink to other materials.

The Alex reader includes applications such as a book reader, mp3 player, web browser, tools to manage annotations of e-reader content, an email client and a calculator. It also allows recording voice comments and adding hyperlinks.

Spring Design plans to release an Android SDK by mid-2010, encouraging developers to create applications for the Alex. As of 11 September 2010 the SDK is not mentioned on the Spring Design website.

Android – Emulator Tutorial

The Android SDK includes a virtual mobile device emulator that runs on your computer. The emulator lets you prototype, develop and test Android applications without using a physical device.
In this chapter we are going to explore different functionalities in the emulator that are present in the real android device.
Creating AVD
If you want to emulate a real device, first crate an AVD with the same device configurations as real device, then launch this AVD from AVD manager.
Creating Snapshots in Eclipse
Creating snapshots mean saving an emulator state to a file that enables the emulator to be started quickly the next time you try to launch it. The one of the biggest advantage of creating snapshots is that it saves the boot up time.
In order to create snapshot, check mark the option of snapshot while creating your AVD.
The first time you launch the emulator , it will take the usual time of loading. But when you close it and start it again, you will see a considerable amount of time reduction in appearing of emulator.
Changing Orientation
Usually by default when you launch the emulator, its orientation is vertical, but you can change it orientation by pressing Ctrl+F11 key from keyboard.
First launch the emulator.
Once it is launched, press Ctrl+F11key to change its orientation. It is shown below:
Emulator Commands.
Apart from just orientation commands, there are other very useful commands of emulator that you should keep in mind while using emulator.

Emulator – Sending SMS
You can emulate sending SMS to your emulator. There are two ways to do that. You can do that from DDMS which can be found in Android studio, or from Telnet.(Network utility found in windows).
Sending SMS through Telnet
Telnet is not enabled by default in windows. You have to enable it to use it. Once enabled you can go to command prompt and start telnet by typing telnet.
In order to send SMS , note down the AVD number which can be found on the title bar of the emulator. It could be like this 5554 e.t.c. Once noted , type this command in command prompt.
telnet localhost 5554
Press enter when you type the command. It is shown below in the figure.
You will see that you are now connected to your emulator. Now type this command to send message.
sms send 1234 “hello”
Once you type this command , hit enter. Now look at the AVD. You will receive a notification displaying that you got a new text message.
Emulator – Making Call
You can easily make phone calls to your emulator using telent client. You need to connect to your emulator from telnet. It is discussed in the sending sms topic above.
After that you will type this command in the telent window to make a call. Its syntax is given below −
gsm call 1234
Once you type this command , hit enter. Now look at the AVD. You will receive a call from the number your put in the command.
Emulator – Transferring files
You can easily transfer files into the emulator and vice versa. In order to do that, you need to select the DDMS utility in Android studio. After that select the file explorer tab
Browse through the explorer and make new folder , view existing contents e.t.c.

9 Advantages of Android Compared to iOS

Android and iOS is the most popular operating systems today. Android is an open operating system of Google, while iOS is Apple’s operating system that is planted on the iPhone, iPad, and iPod Touch.

Actually there are other mobile operating systems such as Windows Phone, BlackBerry OS, Symbian, but the operating system is far behind the number of devotees are compared to Android and iOS. However, until now remained as Android mobile operating system most widely used in the world. Surely it is because Android has several advantages over rival iOS.
 

Advantages of Android devices than iPhone

1. The larger screen

Android-based phones have varied screen sizes, from 3 inches to 7 inches, even for the tablet can be up to 10 inches. Most Android devices are released have a screen diagonal of more than 4 inches and continues to grow because Android is developed by a lot of vendors competing phones make the device operating system Android, so Android mobile phone models vary widely.
 
Meanwhile, the iPhone until now have only two screen sizes, ie 3.5 inches which is applied to the first generation iPhone to the 4S, and 4 inches were applied to the iPhone 5. The iPhone is only developed by Apple, because it was not as fast as Android development.
For the screen size, Android clearly superior to the iPhone.
 
2. Support to SDCard
 
There are only 4 options available capacity on the iPhone, ie 8GB, 16GB, 32GB, and 64GB. The fourth such capacity is set in stone because the iPhone does not provide SDCard slot. That is, users can not add a memory card to expand the capacity of the device.
The majority of Android-based devices are equipped with a slot SDCard. So if the Android device’s internal storage capacity is full, users can add extra storage capacity to enter into external memory slot SDCard.
 
3. Can replace the battery
 
IPhone unibody design does look more elegant, but this design makes battery components can not be overhauled. That is, if there is damage to the battery, the replacement should be done at the service center of Apple.
Most of Android devices use batteries easy to be overhauled, although there but only a small percentage that uses a unibody design that makes the device battery is not easily removable.
 
4. Customize homescreen with widgets, apps, and wallpaper animation
 
IOS, the operating system used on the iPhone has its own grip. Users can not add application shortcuts, widgets, or wallpaper move. In contrast to Android that gives the freedom to do all that.
 
5. Application of digital map that is better
 
If the iPhone has a digital map application Apple Maps, Android has Google Maps to display the data more accurate than digital map applications are made by Apple.
 
6. Android uses a standard USB charger
 
iPhone 5 comes with a charger port that is different from the preceding generation, from 30 pins to only 8 pins. It is very inconvenient if the user has some smartphone devices, because they have to carry more than one charger.
In contrast to most Android devices using a standard charger, micro USB. Users only need to bring one charger for charging different kinds of mobile phones.
 
7. Synchronization of data Google is very easy
 
Android users enough input 1 their Google account to your phone and all the features of Google’s services can be enjoyed. Meanwhile, iPhone users must enter account data one by one to each Google service.
 
8. The open source operating system
 
Users can participate in developing Android, also makes applications and games. Unlike the iPhone, which is a patent of Apple.
 
9. Applications and Games are very varied
 
Because of its open source, developers from around the world can make Android apps and games.
 
That 9 things that makes android is superior compared with IOS.

How To Increase the RAM Capacity on Android with External Memory

Applications and games needed RAM for running. Each of these applications requires different RAM consumption. The new Android devices even support us to run many applications at once (multitasking). Obviously the greater RAM consumed. Problems will often arise if the Android device we have a small RAM. Ranging from hang, enclosed application itself, until suddenly restart. It is critical RAM symptoms because of fullness.

If before we learn how to optimize RAM, now we will learn how to increase the capacity of RAM to external memory. This method requires access to the system, so make sure your Android device is rooted. Select one of the following ways:

Adding RAM Android with Linux Swap
Linux Swap partition on SDCard android was useful as virtual memory or can be called the second RAM. To create a Linux swap partition on your SDCard, please see: Creating Partitions On MicroSD Android

Adding RAM to RAM Manager Pro Android

Its function is similar to Swapper, but its more complete, in addition to adding RAM, can also be set on the condition of multitasking, gaming hard, and hard multitasking. This application can run without partitions on SDCard.

1. First,
Download RAM Manager Pro v5.3.4 APK Via GoogleDrive (free).
Or you can also buy it for USD 3.98 in Playstore.

2. Install the RAM Manager Pro application, then open the application. If there is a request Superuser select Allow.

3. Check Set On Boot, then select the Swap File, a maximum of 256 MB of virtual RAM can be added.

The process of creating a swap file a little longer, about 3-5 minutes. Once the process is complete try to check the File Manager you in sdcard / rammanager, if there is a file named “swapfile” means you have successfully added a Virtual RAM on your Android device!

I hope this helps.

What is Android? Know Android Closer

Problems and Solutions For Android

There may be a problem on your Android device is uncertain. May not have been, or are being, or you will soon encounter problems on your Android. The problems that occurred in the majority of Android we can solve alone, so no need to bring our Android devices to the service center, which of course it will save us money.

How to resolve common problems that occur in the first Android device is aware of the problem, then look for solutions to overcome them. Below is a list of errors that often occur on Android devices:

HANG
Android devices is said to hang if when playing games, browsing, or doing other activities,  sudden jammed Android devices, can not do any process, any button does not work, the touch screen also does not function. This usually happens because the internal memory and RAM devices already too full.

The solution is to remove applications that are not need, it could also move applications to external memory to relieve internal memory. Or to swap memory (RAM to increase the capacity of the external memory) to address RAM fullness.

BOOTLOOP
What is it bootloop? Android device suddenly stalled and restart itself commonly referred to bootloop. If it continues the device will continue to restart repeatedly. Bootloop itself is divided into 3:
-SOFT bootloop

Soft bootloop ie when initially powered on Android devices running normally and able to go to the homescreen. But after some time and then suddenly Hang then restart itself.

– MEDIUM bootloop

As with the bootloop Soft, Medium bootloop This is a condition in which Android devices can not get to the homescreen, but only stopped in bootanimation. But still able to get into Recovery Mode and Download Mode.

– HARD bootloop

Well this is worse. Hard bootloop This is a condition where Android devices when it is turned on only until the vendor logo. Can not go into Recovery Mode but only able to enter into Download Mode.

Bootloop common because there is a mistake when we tamper with the system. The solution is to do a Factory Reset (restore the device to factory settings).

STUCK

If this is the condition in which Android device suddenly jammed in bootlogo, bootsplash, or in bootanimation. It also happens because of our fault when tinkering with the system.

The solution is try to remove battery, then turn it on. If the problem recur, do the Factory Reset.

IMEI LOST

That is when the check IMEI by pressing * # 06 # on the dial board, then IMEI will appear with the number 0 all.

BLANK SCREEN

Usually characterized by a display screen that suddenly was not clear then after that the entire screen is white. Android devices can still function, audible noise, vibration road, it’s just completely blank screen white. Usually because the battery is too hot so damaging lcd / inside HP, LCD connector is loose, or the LCD is already damaged.

The solution is brought to the Service Center and replace the LCD if the LCD problematic.

BRICK
 
Brick is a state where the Android device will not start at all. Brick is divided into two:

-SOFT BRICK

Android devices can not be switched on, can not go into Recovery Mode or Download Mode. Usually caused by overclocking is too high or Fail Flashing.
If the current in-charge is still no sign of an Android device is on, do the Factory Reset with the aid of a PC. Or more safely taken to the Service Center.

-HARD BRICK
Android device could not be used anymore, can be caused due splashed into the water, falling from a high place, and others so that the engine in it broken.
Because it has touched the hardware, the solution is to bring Android devices Service Center to be replaced machines / hardware.
