Use your Android Wear device with an iPhone...

Get your Android Wear device to work cross-platform without hacking...

One of the major problems in the ongoing battle between Apple and Android is the lack of cross-platform integration. Once you’ve committed to one operating system, it becomes very diffi cult to move over as so much of your data, such as your music and photos, refuses to transfer across to the rival platform. Wearables have added another dimension to this issue as an iPhone user may want an Android smartwatch, but then they would not be able to use it with their phone. However, iPhone users can now use some basic functions on their Android Wear device thanks to two new apps. This tutorial will require you to use both an Android and Apple handset in the setup, but after that your smartwatch should be able to sync up with either of your phones. This tutorial will show you how to use both the BLE Utility app and the ‘Aerlink: Wear Connect for iOS’ app in order to turn your Android-only smartwatch into a device that can work with both Android and Apple handsets, giving you many more interesting options for your smartwatch.

1. Download relevant apps.

Download ‘Aerlink: Wear Connect for iOS’ onto your Android phone. It will appear as ‘Aerlink’ on your handset and smartwatch. Download BLE Utility on an iPhone.

2. Locate the Aerlink app

You should already have the Android Wear
app downloaded and your watch synced with your Android phone. Next, tap on the watch’s homescreen where you will see the Aerlink app.

3. Activate iOS Service

Click the app. On the next screen, you will
see a toggle for iOS Service. The slider will be grey; tap it to turn it blue. Your phone will now be able to see and pair with Apple handsets via Bluetooth.

4. Open BLE Utility

BLE Utility fi nds devices that use Bluetooth
Low Energy. Without this, the iPhone still couldn’t locate the watch. Once the app has loaded, tap on Peripheral. This is where the watch will appear.

5. Search for iPhone

Once you had moved the slider, the watch should have told you it had disconnected –this is part of the plan. Tap the magnifying glass icon and it will search for compatible devices to pair with.


6. Pair the phone

When the watch and the phone find each other, this box should appear. Look on the watch’s screen for the code then type in the vacant box. Pairing with an Android phone is a bit simpler.

RecyclerView + CardView example: with Button

This example work on last example of "Gallery-like RecyclerView + CardView example" to show how to add a button and OnClickListener in RecyclerView + CardView. A ImageButton is add over the photo on each cell. Once user click on the ImageButton, the corresponding OnClickListener, to show the info of the corresponding photo.


Modify layout/layout_cardview.xml to add a ImageButton.

Add and Remove view dynamically, another approach

Last post show a example of "Add and Remove view dynamically", each Remove Button have its own OnClickListener object, each OnClickListener object refer to a specified view.

It's another approach: all Remove Buttons share a common OnClickListener object. Inside the OnClickListener, retrieve the associate addView from the trigger view by calling its getParent() method.

Add and Remove view dynamically, keep track of child views

I have a old example of "Add and Remove view dynamically". Somebody ask how the Remove button keep track of the views. So I modify the example to explain in more details.

In this example, when user click on the Add button, it will create a child View, addView. The addView have a Button, buttonRemove. The buttonRemove have its own OnClickListener object. The OnClickListener object refer to the specified addView when it is created.

That means the OnClickListener object of the buttonRemove in the first child view("abc") not the same object in the second child view("abcdef"), not the same object in the third child view("abcdefghi")...All have its own individual OnClickListener object. And each OnClickListener object refer to a specified addView object. Such that it can keep track of the child Views, addView.

100 Times Fastest Technology In Networking is "LiFi":- Tests Prove

With speeds of 1GBps, the technology could enable a high-definition film to be downloaded in seconds

What is LiFi Then:-

LiFi is a disruptive technology which will shift business models and create opportunities ripe for
exploitation. The dominance and lifetime of LED lighting has created a need for new business models in the lighting industry. The need to offer services, including new payment and financing models, creates an unprecedented opportunity for LiFi.



Test Results: Li-Fi is 100 times Faster than Wi-Fi

An Estonian startup company called Velmenni took the technology out of the laboratories and into the real-world offices, and industrial environments in Tallinn for the first time and, believe me, it's really, really fast.

"We are doing a few pilot projects in different industries where we can utilize the VLC technology,"Velmenni's CEO Deepak Solanki told IBTimes UK.

"Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through the light. We're also doing a pilot project with a private client where we're setting up a Li-Fi network to access the Internet in [our] office space."

 Who Invented Li-Fi ?

Li-Fi technology was originated in 2011 by Professor Harald Haas of the University of Edinburgh, who demonstrated that, with a flickering light from a single LED, he could transmit more data than a cellular tower. Professor Haas, delivered a TED talk about his technology in 2011, which has attracted more than 1.7 million views.

YU Testing YU6000, expected to be Yuphoria successor

YU YU6000 appears in GFXBench database, specifications revealed

YU YU6000 specs in GFXBench database

YU a Micromax subsidiary which is yet to complete one year of it's launch is planning ahead very seriously. Their upcoming device YU Yutopia (YU5050) is yet to launch but YU is already testing a new device YU6000 expected to be  YU Yuphoria's successor.

The device's specifications were revealed on GFXBench a graphics benchmark. The device listed was running on SoC: MediaTek MT6753 octa core CPU @1.5GHz a deviation from all Qualcomm Snapdragon based devices from YU. It houses 3GB RAM with 16 GB ROM. The camera listed is 12 MP rear with 7 MP front snapper which could easily be 13MP/8MP combo. It will have 4.6" FHD screen. The device comes with usual set of sensors. 

It looks pretty good on paper as Yuphoria successor if they price it similar to Yuphoria which was launched with initial price tag of ₹6,999. MediaTek MT6753 which is equivalent to Snapdragon 615.

However we do advise you to take this with a pinch of salt as the tests can easily be fooled.

socket.getInetAddress() return null on Android 5

Refer to last example of "Simple HTTP server running on Android", it work on Xiaomi Redmi 2 running Android 4.4.4. But somebody report program stopped on Android 5 devices. So I re-test on Nexus 7 running Android 5.1.1. Yes, the app crash! caused by NullPointerException, because socket.getInetAddress() return null.

Modify MainActivity.java to capture socket.getInetAddress() before and after close():

            return;
        }
    }
}

It's found that on Xiaomi Redmi 2 running Android 4.4.4, socket.getInetAddress() keep no change before and after close().

But on Nexus 7 running Android 5.1.1, change to null after close().

So, we have to read socket.getInetAddress() before close().

Simple HTTP server running on Android

It's my old exercise "Implement simple HTTP server running on Android". Somebody report it's not work, so I re-try it on Android Studio. Actually the code is same as before, and work as expected. Please notice both the server and client have to connect in the same WiFi network.

Updated@2015-11-26:
This code NOT work on Android 5, may be all 5+ version.
Fixed, refer next post "socket.getInetAddress() return null on Android 5".

YU Yunique CyanogenMod Nightlies are Now Available to Install

Install CyanogenMod on YU Yunique now

CyanogenMod Nightlies for YU Yunique

YU Yunique launch few months ago in September with a price tag of  ₹4,999 was the first device from YU to come with Pure Android. It was strange given Cyanogen was the selling point of YU Televentures. However Yunique was promised a Cyanogen OS later for those who prefer customization and tinkering with their phone. But despite being more than two months since the launch of Yunique there's no release in sight which matches with the delayed release of Cyanogen OS 12.1 for Yureka, Yureka Plus and Yuphoria.

CyanogenMod community has once again beaten the Cyanogen and released the first build of CyanogenMod 12.1 for Yunique with a codename 'jalebi'. If you've been waiting for Cyanogen experience on your Yunique, you can go ahead and download the nightlies from the CM website here. Be warned though that this is not official and may contain bugs and/or missing features. So do check the build log before installing. 

If you'd like to know more about the CyanogenMod and differences between Cyanogen OS and CyanogenMod read this wiki here.
