Share files with others using Wi-Fi Direct

Published by:

Connecting devices directly to one another is often seen as the job of Bluetooth, but Android offers another option in the shape of Wi-Fi Direct. So, what is Wi-Fi Direct? It is a wireless technology that enables users to connect directly. There is no need for users to be connected to a network or hotspot. However, users will need to have Android 4.0 or later to take advantage of the feature. Wi-Fi Direct is effectively a peer-to-peer connection and enables users to interact and operate, like Bluetooth, but at a greater range. Wi-Fi Direct is hidden away within the Settings menu and users will not find the feature with a cursory glance. A look inside the Wireless & Networks Wi-Fi settings menu reveals the hidden Wi-Fi Direct feature. Wi-Fi will need to be switched on for Wi-Fi Direct to be active. In addition, Wi-Fi Direct will need to be enabled on all devices that wish to connect. Multiple devices can be connected this way, dependent on support, ready to share files in double-quick time.

Wi-Fi Direct


Step by Step How to use Wi-Fi Direct

Find Wi-Fi Direct

To start using Wi-Fi Direct, you’ll need to first head to the Settings app on your Android device. This will display Wi-Fi under Wireless & Networks. This needs to be switched on for Wi-Fi Direct to work. Tap Wi-Fi to open and select Wi-Fi Direct from the menu.


The moment that Wi-Fi Direct is tapped in the menu the device will start searching for other devices. Only devices with Wi-Fi Direct switched on will be picked up. Before switching on another device, first take a note of the name given to the device. You’ll need this later on.

Other device

To connect two devices together, both need to have Wi-Fi Direct switched on. On the second device follow the instructions in step 1 to make sure that Wi-Fi is on along with Wi-Fi Direct. Again make a mental note of the name assigned to the second device.

Peer devices

The second device will now display the name it has been assigned along with the name of the other device under the Peer Devices heading. Hit search on the first device to display the name of the other device. Now both devices will be displaying a name under Peer Devices.

Send an invite

Connecting the two devices can be done on either device. Tap the name of the device, under Peer Devices and the Available line will change to Invited. This informs the user that an invitation has been sent to the selected device and is awaiting a reply.

Get connected

The receiving device will now have a message on screen named Invitation to connect. The user can now choose whether to accept the invitation or decline the invitation. Once the invitation has been accepted the two devices will wait to connect.

Up and running

When a device is connected, the status of both devices will change to connected. Heading back to the Wi-Fi list, the Wi-Fi Direct connection will now be there. This will adopt the name assigned to the connection under groups, eg DIRECT-0t-Android_93e94.

Rename device

The Wi-Fi Direct feature automatically assigns a name to the current device. The name is typically a prefix of Android with an alphanumeric after, eg Android e_895. Tap Rename device to give the device a more instantly recognizable name, making it easier to identify.

Remember groups

Each time a connection is made it is assigned an ID (see step 7). The connection details are stored for future use under Remembered Groups. This enables the same devices to connect without having to be invited. Tap the connection to remove or forget the group.

Multiple connections

Wi-Fi Direct offers the option to connect to more than a single device. However, it is worth noting that this feature is not supported on every device. If the feature is supported users will see Available devices with a check box next to it. Tap the checkbox next to the devices to connect.

Share an image

When a device or devices are connected with each other, users can start to transfer fi les from one device to another. To share an image, locate the folder that contains the images, for example, Gallery. Tap to select an image, then the Share icon and select Wi-Fi Direct.

Sharing files

Sharing files via Wi-Fi Direct is much the same process as using other options. Select the file, folder or app to share and tap the related Share icon. From the list, select Wi-Fi Direct to share. Note that Wi-Fi Direct will only appear on supported devices.


Wi-Fi Direct will keep the connection behind devices active until the user chooses to terminate the connection. To disconnect a device, simply head to the Wi-Fi screen and tap the name of the connected device. A message will appear; press OK to disconnect the current device.

Android Apps development

Published by:

Android apps is using by millions of users now the days. Android is the most usable OS in the world now. There is more than 1.2 Billion Android apps users worldwide. Here I will discuss with you “How to develop Android apps”? Showing you some of the basic points that you have to keep in mind before Start developing Android apps.


Learn the language for Android Apps

Predominantly, Android apps are written in Java. There are multiple versions of Java available for Android developers, with most using the x86 versions over the sometime problematic 64-bit version.

Using XML

At the backbone of what makes certain Android apps look great is XML. Using XML is a relatively easy way to take complete control of each and every design aspect of the app, without losing hours and hours stuck in messy code.

DIY apps

By scouring the web, you’ll now find several online app creators, enabling everyone to produce their own app. The MIT App Inventor is fairly straightforward for everyday users to get to grips with.

Do I need Android Studio?

Yes! Android Studio is a complete package for developers, helping them create, debug and test any new application. For new developers, it includes a template wizard which takes you through the entire development process.

Tools of the trade

The key thing any developer will need is to download the Android SDK file. Game developers will want to also download the Unreal Development Kit which powers many AAA mobile gaming titles.

Testing apps

The Android SDK fi le includes ‘monkeyrunner’, an API that can be used to scrutinize each aspect of the app before publishing. For seasoned developers, there’s also the much more advanced JUnit.

Learn SQL

Android uses SQLite to help keep a database of the inner workings of your app. The version that Android users have access to is a more stripped back offering than the full SQL database.

Tablet apps made easy

Use Android Studio to ensure your app is also tailored for tablets and other devices. Within this suite you can implement flexible layouts which can then be optimized to fit a wide range of screen sizes.

Master the Android Asset Studio

Everything from the Roboto font to the inner workings of the Holo theme can be found in the Android Asset Studio. It’s the best way to keep your app in line with pure Android.

The cost of publishing

Google charge a one-off fee of $25 to distribute apps. When uploading an app, the APK can’t be bigger than 50MB. You can include up to 4GB of additional file downloads if needed.

Built-in Windows 8 tweaks

Published by:

Windows 8 offers all kinds of customization opportunities, and the first crops up only seconds after you turn on your PC. How would you like to have your PC display a custom message before the Lock screen appears? It could be a reminder or a even a warning of some kind. Setting this up is easy. First launch REGEDIT and browse to HKEY_LOCAL_ MACHINESOFTWAREMicrosoft Windows NTCurrentVersionWinlogon. Then double-click the option ‘LegalNoticeCaption’ and set its value to the title of your message. Double-click ‘LegalNoticeText’ and set its value to the message itself. That’s it, you’re done – the message will appear when you next reboot. With any welcome message out of the way, you’ll normally see the standard Windows 8 Lock screen. The default background image in windows 8 is a bit bland, but the Bing app can help you find a new one. Launch it and check out the current images, then right-click on your favorite and select ‘Set As Lock screen’ to use it.

Windows 8 tweaks

Start screen

The Start Screen looks great in windows 8, but one problem is you get very little control over the size of your Live tiles. One way around this is to tell the system you have a different size monitor. Windows 8 may then re-scale your Start screen to make the tiles larger or smaller. Launch REGEDIT and browse to HKEY_LOCAL_MACHINESOFTWARE MicrosoftWindowsCurrentVersion ExplorerScaling (create the Scaling key if you don’t see it). Right-click in the right-hand pane, select ‘New > String value’ and call it Monitor Size. Double-click ‘MonitorSize’, and give it a value representing the monitor size (in inches) you’d like to use – ‘21’, for example. Using a value larger than your actual monitor size should produce smaller tile sizes, while a smaller value normally increases tile size. This doesn’t always work, and you may have to experiment with different values, but it’s worth a try. Don’t forget you’ll need to reboot to see changes.

Coping with faulty hardware

Your PC’s failing? Here’s how to get by…

Even the most expensive PC can be brought down by simple problems, like a mouse that stops working, but there are some tricks to help you get by. Click ‘Control panel > Ease of access > Change how your mouse works > Turn on Mouse keys’. Click ‘setup Mouse keys’ to configure your system, then you’ll be able to use the arrow keys on your numeric keypad to move the mouse cursor, left-click, etc. Your speakers have stopped working? Click ‘Ease of access > Replace sounds with visual clues’, check ‘Turn on visual notification for sound’ and you can setup your PC to flash a program window, for instance. If your keyboard has failed, then running OSK.EXE (the on-screen keyboard) will help until you can get another. Maybe you can’t see the text cursor on a laptop screen – click ‘Ease of access > Optimize visual display’ and increase its thickness to whatever you like.

Revitalize your desktop

Refresh your PC with new backgrounds, icons, sounds and more If you’re bored of the regular Windows desktop wallpaper then right-click the desktop, click ‘Personalise > Desktop background’ and you can choose from various bundled images, your own pictures and even solid colours. If that’s not enough, right-click the desktop, click ‘Personalise > Get more themes online’ and a browser window will open at Microsoft’s Themes page. A Theme is a collection of backgrounds, colours and sounds, and the site has hundreds available, organised into categories like animals, art, movies, landscapes and more. Just browse the site, and download what you need. Sometimes you might like just one wallpaper from a theme, but this doesn’t have to be a problem. Extract the contents of the theme pack file (or install 7-Zip from and use whatever images you need.

Launch Windows 8 apps from the desktop

You don’t need to use the Start screen to access apps – we’ll show you how If you spend most of your time on the Windows 8 desktop, then accessing an app isn’t straightforward. You’ll normally have to switch back to the Start or Search screens, then find and launch it manually. Create the right shortcut, though, and you could launch any of the regular Windows 8 apps directly from your Taskbar. To try this with the New app, right-click your desktop and select ‘New > Shortcut’. Type cmd.exe /c start bingnews: && exit into the Location box and click ‘Next’. Type News as the name and click ‘Finish’. Right-click the new shortcut, select ‘Properties > Change icon’ and choose something appropriate. Sites like have lots of free icons to try. You can now double-click the icon at any time to launch the News app. This handy solution also works well with other apps, so feel free to get customising your Taskbar!

Set your default programs

Launch the right application whenever you double-click a file In theory, double-clicking a photo should open it in your favourite image editor. Windows 8 doesn’t always use the right default programs, but it’s easy to fix. Launch Control Panel and click ‘Programs > Set your default programs’. Browse the list of programs on the left, looking for and selecting whatever you’d prefer to use to open JPEG’s or any other file type. If you want that program to handle every file type it possibly can, click ‘Set this program as default’. If you would like more control, click ‘Choose defaults for this program’ and you’ll see a list of every file type the program can open. Check the box next to anything you’d like it to handle (or check ‘Select all’ for the full set), click ‘Save’, and double-clicking a file of that type should open it in the

Master Facebook privacy settings page to keep your all-important personal information private. Despite only being founded in 2004, Facebook now has well over a billion users sharing their thoughts, photos and more. However, as it’s grown in popularity – and with people putting more and more personal details on the site – the question of privacy has come firmly to the fore for Facebook users. The really worrying thing about all this is that criminals can easily gain access to your information, making it simple for them to target you – whether that’s with seemingly harmless spam, or by stealing your identity. Facebook doesn’t make it obvious that your privacy is at stake, either. The good news, however, is that you can easily adjust Facebook’s settings to determine exactly which people get to see what’s on your profile.

New Facebook privacy controls

When you share on Facebook, make sure you’re sharing it to the people you want to, otherwise it’ll go out indiscriminately to everyone on your Friends list. If you’re not careful, it may even go out to everyone on Facebook. On your main Facebook homepage, click on the drop-down arrow next to Home and select ‘Privacy Settings’ from the list that appears.

Access restrictions

You can lock down your entire profile in one fell swoop ensuring any future updates can only be viewed by a select few. Click on the ‘Edit’ option next to ‘Who can see your future posts?’ and then choose ‘Custom’ from the drop-down menu that appears. To ensure only your approved friends can see your updates, click ‘Share this with’ and select ‘Friends’.

Extra control

If you want to be a little more particular about who you share with, click on ‘Specific People or Lists’ and in the text box below type the name of the person or organisation that you want to share all your updates with. Alternatively, if you want to exclude a certain person, group or organisation, type the names in the text box underneath ‘Hide this from’.

Share on the fly

Alternatively, you might want to choose who you share with as and when you make an individual update to your Facebook account. To do this, write something in the status box on your profile page or choose a photo to share – when you’re ready, click the drop-down menu button next to ‘Post’ and select who you want to add to from the list that’s generated.

Disguising your presence

To gain a little more control over your other Facebook activities, go back to the main page on your Facebook account and click on the little ‘padlock’ icon next to the Home button. Now, under ‘Who can contact me?’ click on the drop-down menu located underneath ‘Who can send me friend requests’ and select the option called ‘Friends of friends.

Play tag

If a friend tags you in a photo on Facebook, it will automatically appear on your Timeline – but what if you don’t want it to? The answer is to get Facebook to request your permission each time. To do this, Go to your homepage, click on ‘Activity log > Posts You’re Tagged In’. From here, hit the ‘gear’ icon at the top and enable the ‘Timeline Review’ controls.


Hide from search engines

You can’t escape being publicly searched for, but if you keep your profile private, nobody can see what your status updates or photos. You can also make sure your Timeline doesn’t appear in searches, too. Go to ‘Privacy Settings > Who can look me up > Do you want other…’, click ‘Edit’ – from here, untick ‘Let other search engines link to your Timeline’.

See how you look

It’s a good idea to check how your page looks to the rest of the world – this will give you an idea of just how private (or open) it is. Navigate to your profile page ‘cog’ icon, and in the drop-down menu select ‘View As’. By default, it appears as ‘Public’, but you can set it to appear as a specific person. Hit ‘OK’-now your Facebook page will be as private as you want it to be.

10 Things you need to know about Android Privacy

Published by:

Every time when we use Android we should aware about some privacy Settings. Here I am showing you some tips that you need to know about Android Privacy.

Hide apps

There are plenty of apps available on the Play store that can help password protect the apps stored on your phone. One of the best is NQ Mobile Vault, which adds an individual PIN number to each app, enabling you to keep them safe from prying eyes. This is particularly useful if you use your phone for mobile banking.

Remain hidden online

All of the main Android web browsers contain a private browsing feature of some kind that enables you to browse the internet without leaving any virtual track of what you’ve been searching for, or the websites you’ve been visiting. Perfect if you’ve been doing some present shopping.

Stop Intruders

Some applications come with a brilliant feature that will take a snapshot of anyone who tries to get into your phone when you’re not near your device. This is a great feature to add if you want to keep messages, emails and other files private.

Manage Google apps

There’s no denying that Google collects a lot of data about you through its range of apps, but it’s easy enough to remove and stop any collected data getting to the internet giant. Go on to the Chrome Browser and find the Apps section from which you’ll be able to manage each individual Google app and control the data it has collected.

Facebook posts

Depending on how open you’re on Facebook, it’s possible to keep your posts private from everyone on your friends’ list and instead specifically select the people you want to share that post with. A great way of keeping on top of privacy.

Location sharing

Another key privacy issue to consider is geo-tagging, especially when you create posts on various social media sites. If your GPS isn’t turned off you’ll find that most sites include a location sharing feature that lets people know exactly where your current location is when you post.

Checking app permissions

When you download an app, make sure that you check out the various app permissions that come as standard. With many of the bigger applications, especially social media ones, you’ll find that permissions can be pretty intrusive on your device. Have a close look at them.

Online storage (making files private)

Apps like Google Drive and Dropbox are great solutions for those needing some cloud storage, but one of the features that are usually forgotten about is that each fi le you upload can be made privately available to a handful of users.

Removing search history

Every time you conduct a Google search, the app automatically saves the history of the search. Google in turn will then target adverts at you based on your history. Go to the Settings in Google Search to remove your history and to keep your searches private.

What has been reported?

One app you should definitely download is Clueful, a clever piece of software that shows you how your installed apps use your data. The software then scans the applications on your device in great detail to provide fixes from them and make them safe to use without your data being distributed around.
