Configuring Android SDK on Windows

Getting started with Android Development (whether using Cordova or Native) can be a little tricky for complete beginners. One hurdle is the configuration of Environment Variables required to execute all Android commands easily using command prompt.


Here is how to configure all environment variables in Windows that you need to build an Android App. I am assuming that you have already downloaded and installed the latest version of Android Studio from here.

  1. Right-click on ‘My Computer’ and select Properties.
  2. Go to Advanced system settings and select ‘Environmental Variables’ option.
  3. Under the User Variable table, click New to open New User Variable dialog.
  4. Put ANDROID_HOME as Variable name and provide the path of the SDK folder next to Variable value.
  5. Go to the folder where SDK has been installed.
  6. Inside the SDK folder look for ‘tools’ and ‘platform-tools’ folder.
  7. Copy the path for both tools and platform-tools.
  8. Open ‘Environmental Variables’ dialog box.
  9. Go to System Variables table and locate the Path variable.
  10. Edit the path variable from ‘Edit system Variables’ dialog box.
  11. Add the ‘tools’ and platform-tools’ folder’s full path at the end of the path string. Make sure that all paths are separated by semi-colons.
  12. Close the entire opened dialog box.
  13. This configures the Android. However, to check open the command prompt.
  14. Type the command ‘android’. This will open the Android SDK Manager dialog box,


That is all. Feel free to comment below if you face any problems.


Hello: From Facebook

Facebook announces ‘Hello’ a new dialer app for Android devices. The app is designed as a dialer replacement on your phone and comes with features like caller ID. Hello is being rolling out for public testing in the US, Nigeria and Brazil and can be downloaded for free from the Google Play Store.

The app is a part of Facebook’s Creative Labs initiative for building standalone apps. The dialer is fully compatible with Facebook account and allows users to make calls with Facebook Messenger instead of using their cellular connection.

Dialer is made on Google’s Material Design principles, and is divided into four main tabs: recent calls, the dialer, contacts, and settings. The app is very similar to caller ID app TrueCaller and provides the callers information regardless of whether or not you have the caller’s phone number in your phone contacts list. Facebook will attempt to match any number with a user profile even if its not in your contact list. If it finds a match, and the user has chosen to let Facebook users find them by their phone number, the person profile will pop up. Users will be able to see the callers Hometown, profile pics, any mutual friends, among other information. After the call, users will be able to view the callers email address and website, if they’ve added one to their profile.- See more at:

Twitter Opt-in to get Direct Messages

Twitter has for years tested a feature that would allow anyone to opt in to receive direct messages from other users on its platform, even if the accounts weren’t following each other as per earlier requirements. This setting was rolled out more broadly to a portion of Twitter’s user base in 2013, but never became an option for the general public. That changes today, says Twitter, which announced this morning that anyone on its network can now opt to accept direct messages from any other Twitter user.

Previously, in order to receive a direct message from another person, you would have to be following that user on Twitter. For some public figures, and especially for journalists, that restriction made it difficult to communicate more privately. For reporters, it could also potentially tip people off about one’s sources, since users would have to engage in public tweets asking to get a follow back so they could send that direct message in the first place.

In the past, Twitter users including brands and some verified users have been able to, in some cases, enable a setting that would open up their Direct Message inbox to anyone. But now any Twitter user can turn this option on for themselves if they choose. (Twitter says the feature is rolling out now , so if you don’t yet see it in your Settings, just check back in a bit.)

Related to this change, the company is also updating its messaging rules so you can reply to incoming DMs regardless of whether that person follows you in return.

And to better highlight the newly added option, Twitter says that a new Direct Message button will appear on profile pages on both Android and iPhone. This button will only appear on the profiles of people you can send Direct Messages to, making it more obvious with a glance who’s turned the feature on already.

Finally, if someone who has the “Receive Direct Messages from anyone setting” switched on begins to receive spam or abuse, they can still block the abuser on Twitter in order to stop that account from being able to DM them.

The updates come at a time when Twitter has been focusing heavily on improving the Direct Messaging for its users, in light of a shift in the mobile application ecosystem which sees private communication apps like Snapchat and WhatsApp significantly growing their respective user bases and increasing their users’ engagement. Snapchat reportedly has some 200 million monthly users. WhatsApp recently announced 800 million users. Twitter, however, has 288 million monthly actives.

The company may be hoping that by improving its private messaging functionality, it can grow the number of users who register for accounts as opposed to those who more passively use its service only to view tweets. In recent months, Twitter has rolled out a number of changes to DM’s, including support for group DM’s and the ability to share public tweets via DM’s, for instance.

WhatsApp adds Google Drive backup feature

WhatsApp CEO Jan Koum has confirmed that the app has crossed 800 million monthly active users milestone. The messaging app has also launched chat backup/restore options on Google Drive in the latest update for Android users.

WhatsApp CEO Jan Koum has confirmed that the app has crossed 800 million monthly active users milestone. The messaging app has also launched chat backup/restore options on Google Drive in the latest update for Android users.

Jan Koum in his Facebook post takes a dig at other messaging apps who disclose registered users instead of active users. He wrote, “WhatsApp – now serving 800,000,000 monthly active users. Reminder for the press out there: active and registered users are not the same thing.”

WhatsApp crossed 700 million active users in January, and has added over 100 million users in just four months. The popular messaging app is expected to cross 1 billion monthly active users milestone by the end of this year. WhatsApp recently announced free voice calling feature for Android users, and is expected to launch it for Windows Phone, Blackberry and iOS platforms later this year.

The company has also rolled out backup/ restore options for chat history and media via Google Drive.


The feature will help users to have the messages backup in case they switch off or lose their smartphone. The Google Drive Backup option can be accessed via Settings and users can select the frequency of data transfer from daily, weekly or monthly options. It also has a ‘Backup Now’ option that allows users to transfer the data instantly. Users can also choose to transfer data through Wi-Fi or data. Currently the feature has been rolled out in the latest Android Version v2.12.45, and may be rolled out to other platforms later.
