How to take screenshot in android device without a third party app?

I have been using android for three years and it's first time that I know how to screenshot in android device, and without using a third party application. Below is the way to do it:

Press and hold down the Power and Volume-down buttons simultaneously
And you will hear a "Beep" sound and see an animation that let you know that the screenshot is taken, and you can use Gallery app or any image app to view it.

Simple as it is!

Good Email App for Pad: TouchDown HD

Our company's email account will force a security setting, which will compel you to use a screen lock with PIN or password etc. This is to say, every time the screen is turned on and off, you need to type the PIN to unlock it.


We understand that this is very important for company security, because the device may contain sensitive information. But it needs to frequently input the password, which is so inconvenient. How can we overcome it? Now we have found a tool that can both satisfy the security needs and avoid the inconvenience of typing the password.

The solution is to use a app called: TouchDown HD.

It contains calendar, email and contacts tabs, and it has powerful configuration settings.
And most importantly, when you configure the email account using TouchDown HD, it only locks itself. The device is not locked, so that you don't need to input password every time you turn on the device.

Download mp3 in embedded player - Using fiddler

We all have experiences that  we open a webpage and have listened to a wonderful song, and we want to save it. But many times the song is played by a Flash player, or to say, it's embedded. Like the picture shown below:



How can find the source of the audio file and start to download it?

Here comes the solution - Fiddler
Fiddler is a great tool that helps you analyze web traffic, for more information you can refer to http://fiddler2.com/



1. I opened the webpage and start to analyze the web traffic
For example, the webpage is: http://tw.streetvoice.com/music/shin260/song/105109/


2. Through analysis on the web traffic,

I found that it's calling a api to play audio, and the JSON result is the songURL.

3. I put the song URL in browser and get a way to save the music.


OK, that's done.

I also would like to share the song and the lyric.
