Android devices

There are lots of different Android devices on the market, ranging from from small screen phones to 10 inch tablets. These instructions are mostly general to Android devices, though there are variations depending on the version of Android used on the device and possible customizations done by the manufacturer.

Where applicable, instructions are made specifically for Samsung Galaxy Mini phones, Samsung Galaxy Tab 2 tablets and the A13-MID tablets, since all of these are used with the GraphoLearn research projects. When referring to PC computers, the instructions assume a Windows operating system.

Accessories

Included with any Android device should be a charger for the device.

Phones usually use a regular Micro USB cable as both the charger cable and the connection cable. Sometimes the USB cable can be detached from the charger to use it as a regular USB cable. The devices can also be charged from a USB port on a computer.

Tablets often have different kinds of cables. The Samsung tablets use a wide, flat 30-pin USB cable and the A13-MID tablets have a separate power cord.

Android basics

This chapter deals with the basic usage of Android devices and the various buttons, gestures and apps you need to use with the device.

Screen

The most prominent feature and the main interaction method with the device is the touch screen. The screen is usually protected during storage with a plastic film, that should be removed. The screens are quite resistant to scratches when using them, but you should not store them for example in a pocket with keys.

The screen can be cleaned using a dry or slightly damp cloth, preferably a microfiber cloth like one would use to clean a laptop’s screen or eyeglasses. Avoid dirty or rough cloths and do not use detergents.

Physical buttons

On every device there’s at least two physical buttons, the power button and the volume button.

Power button

The power button is used to turn the device on/off and to turn the screen on/off.

To start the device, hold down the power button until the screen turns on.

When the device is on, a long press of the power button brings up the close menu, from which you can choose to shut the device down.

NOTE:If a device seems frozen for a long time and does not respond to touch gestures, you can shutdown/restart a device by holding the power button down for 10 seconds. If you can’t turn a device on, first try charging it for at least 10 minutes in case the battery has run out. If you have any other problems with a device, first try shutting it down and turning it back on and see if the problem persists.

Volume button

The volume button is used to control the volume on the device. On phones it controls the ringer volume by default. On tablets or when in an application that plays sounds on phones, it controls the media volume, which includes the sounds played by GraphoGame.

Sound volume can also be changed from the Settings menu.

Touch gestures

The touch screen is the primary interaction method with devices and there are several types of gestures that can be used.

You can watch clarifying videos about the various touch gestures in Wikipedia.

You may also want to change the screen timeout in Settings -> Display to for example 2 minutes, so the screen does not turn off every time you don’t touch it for a moment. You can also disable the auto-rotation of the screen in the display settings.

Internet connection

Depending on the device, there may be several different methods for internet connection.

WiFi

WiFi connection is supported by all Android devices. You can toggle WiFi connection on/off from the notification menu or from the Wireless & Networks menu in settings.

Mobile internet

Using a mobile internet connection requires SIM card support from the device and a SIM card with a data plan from the operator. You can enable or disable mobile data usage from the notification menu or the Wireless & Networks menu in settings.

WiFi tethering

If you have a device with WiFi and a mobile data connection, it is often possible to share the mobile connection through WiFi, effectively changing the device into a mobile WiFi hotspot. This may help in situations, where you need internet access on a tablet that only has WiFi support but there’s no WiFi hotspot available. Look for settings called WiFi tethering or WiFi hotspot to enable this.

Copying files between devices

There are various ways to copy files either between an Android device and a PC or between Android devices. This chapter deals with the most common methods.

Connecting to PC with USB cable

Perhaps the easiest way to connect an Android device with a PC computer is via a USB cable. If the device is not automatically detected by the PC, you may need to download drivers from Windows Update or from the device manufacturer’s site.

With Samsung devices you will need at least Windows XP SP2 and possibly an internet connection so that the PC can fetch drivers from Windows Update. If the PC fails to recognize the Samsung device, you may need to download and install the Samsung Kies software from the Samsung web site at http://www.samsung.com/kies/ .

USB troubleshooting

In case the device isn’t recognized by the PC, some of the following tips may help.

  • Make sure the USB debugging option is off in Settings -> Developer options
  • Try restarting both the device and the PC, then reconnect.
  • Try a different USB port
  • Try a different USB cable
  • If nothing helps, try some other method to transfer files

File Browser on device

To access files on an Android device, you need to use a file browser app. Depending on the device, there may be a pre-installed app available. Samsung devices have an app called My Files, while the A13-MID tablets have an app called File Manager. It is also possible to install a file browser app from the Play Market, such as the free ES File Explorer.

External microSD card

Most Android devices support microSD memory cards. You can also use SD cards with a PC with a a card reader. To use a memory card with an Android device, insert the card in the slot on the device and the device should automatically recognize it. Be sure to go to Settings -> Storage and unmount the card before removing it if you copied file to the memory card, or you might risk losing or corrupting files.

External USB memory

Most new Android devices support USB On The Go (OTG), where you can connect a USB device straight to the Android device with a special USB OTG adapter. This allows you to use a USB memory stick to copy files to and from the device, just like with a microSD memory card.

Bluetooth

If the device has Bluetooth capability, it is also possible to pair the device with another device (PC, phone, tablet etc.) using Bluetooth. Instructions can be found at http://support.google.com/android/bin/answer.py?hl=en&answer=1650159.

Once a Bluetooth connection is established, you can send files by navigating to the with a file browser, long pressing on the file and selecting Send -> Bluetooth. Received files will be found in a folder called /bluetooth/.

WiFi

If you have WiFi access on the device and the PC has an internet connection, you can also transfer files by internet using for example Dropbox. When connected through a WiFi, you can also access shared folders on local networks using a file browser that supports it, for example ES File Explorer.

Installing third party apps

NOTE: You need go to the settings and turn on Unknown sources before trying to install GraphoGame or any other app outside the Play Market. This enables installation of software from outside the Play Market and is necessary to install GraphoGame. You can find the setting in Settings -> Security -> Unknown Sources.

First you need to copy the application package file (APK) to the device. You can either download it directly to the device using the internet browser or copy it from a PC or another device using any method.

Once you have the APK on the device, you need to locate it with a file browser. Touch the APK file to start the installation. If there is already a previous version off the application, you get a prompt asking you if you want to overwrite it. Choose OK and then again OK in the next prompt to accept the program’s permissions and install the app.

To uninstall an application, go to Settings -> Apps / Applications manager to see a list of all the installed apps. Touch an app to open the app info, where you have various options including Uninstall.

 

Google account and Play Store

To get the most out of an Android device, it should be used with a Google account. This allows access to the Play Store, where you can get free and paid apps for your device. Note that GraphoGame is not currently distributed through the Play Store and a Google account is not necessary to play GraphoGame.

If you already have a Google account, you can use it with any Android device. To add an account, go to Settings -> Accounts & sync and choose Add account in the top right corner and choose the type of account from the list. With a Google account you can then choose to create a new account or use an existing one.

NOTE: If the device is not restricted to personal use, you should not use your personal Google account, since that gives anyone using the tablet access to your Gmail account. If the device is shared and for example used by kids in a school, you can opt not to use a Google account on the device at all or create a new account that does not contain any personal data.

Once you have a Google account connected with the device, you can use the Play Store. There are lots of free apps that you can download and use for free. There are also paid apps that you need to purchase before using. For purchasing apps you need a credit card and a Google Wallet account.
