Install Android Studio & Java8

Install Java JDK 1.8

  • Download jdk-8uversion-linux-x64.tar.gz file from http://www.oracle.com/technetwork/java/javase/downloads/index.html
  • Unpack the tarball and install the JDK.
    % tar zxvf jdk-8uversion-linux-x64.tar.gz
  • Set up the JAVA_HOME and ANDROID_HOME
    For example, ANDROID_HOME=/home/demo/java/exo-dependencies/Android/AndroidStudio_Latest/SDK
    JAVA_HOME=/home/demo/java/jdk1.8.0_77
    PATH=/usr/local/bin:$PATH:$JAVA_HOME/bin:$M2_HOME/bin:$GRADLE_HOME/bin:$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools
Install Android Studio on Ubuntu
Setting up Android Studio takes just a few clicks.
While the Android Studio download completes, verify which version of the JDK you have: open a command line and type javac -version. If the JDK is not available or the version is lower than 1.8, download the Java SE Development Kit 8.
To install Android Studio on Linux, proceed as follows:
  1. Unpack the .zip file you downloaded to an appropriate location for your applications, such as within /usr/local/for your user profile, or /opt/ for shared users.
  2. To launch Android Studio, open a terminal, navigate to the android-studio/bin/ directory, and executestudio.sh.
    Tip: Add android-studio/bin/ to your PATH environment variable so you can start Android Studio from any directory.
  3. Select whether you want to import previous Android Studio settings or not, then click OK.
  4. The Android Studio Setup Wizard guides you though the rest of the setup, which includes downloading Android SDK components that are required for development.
Note: If you are running a 64-bit version of Ubuntu, you need to install some 32-bit libraries with the following command:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
If you are running 64-bit Fedora, the command is:
sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686
That's it! The following video shows each step of the recommended setup procedure.

Install appium on Ubuntu14.04

Requirements

Your environment needs to be setup for the particular mobile platforms that you want to run tests on. See below for particular platform requirements.
If you want to run Appium via an npm install, hack with or contribute to Appium, you will need node.js and npm 0.10 or greater (use n or brew install node to install Node.js. Make sure you have not installed Node or Appium with sudo, otherwise you'll run into problems). We recommend the latest stable version.

Skype headphone & microphone & meeting

Headphone (speaker/line out) & microphone(Line-in) để làm một cuộc đàm thoại qua skype

Có 3 jack cắm ở soudcard:
  1. Line-out jack để cắm loa khi nghe người đàm thoại nói hoặc nghe phần mềm âm thanh phát ra từ máy tính.
  2. Microphone jack dùng để cắm microphone dùng để nói vào máy tính rồi máy tính sẽ ghi lại và truyền qua mạng tới người đàm thoại.
  3. Line-in jack this is for connecting a CD-player or cassette tape to the computer.
Playback(phát lại) là điều khiển âm lượng cho chế độ phát âm thanh
Recording là điều khiển âm lượng cho chế độ thu âm.


Audio devices in Windows 7 (and not only this version of Windows) are those devices which you can use to play or record audio. This means that every time you listen to your favorite songs or talk on the microphone you are using audio devices. When you listen to music, or any sound that comes from your computer, you use the playback functionality to hear the sounds in the speakers. On the other hand, when talking about the recording functionality, the audio device makes it possible to record any sound you like, be it from your microphone (recording your voice) or from the computer (recording sounds produced by your playback device).
The Set Default has two options: Default Communication Device which handles all communications such as calls or video conferences done on IM or VOIP and Default Device which handles all the output done without the communication part (if the Default Communication Device is set).
Many computers have three or more jacks that connect to a sound card or sound processor, including a microphone jack, line-in jack, and line-out jack. Your speakers should be plugged in to the line-out jack. If you're not sure which jack this is, try plugging your speakers in to each of the jacks to see if any of them produce sound.

A "Line in" jack is used to imput an audio signal to the computer e.g you can run a minijack to minijack between a CD player and the line-in port and the sound would come out of your PC's speakers, it is very useful also if you have a laptop with rubbish speakers, I do it with mine and it works beautifuly, p.s you can also do the same thing with a microphone socket.
Sound card color code:
ColorConnector
Lime GreenLine-Out, Front Speakers, Headphones
PinkMicrophone
Light BlueStereo Line In
OrangeSubwoofer and Center out
BlackRear Surround Speakers for 5.1 and 7.1 systems
GrayMiddle Surround Speakers for 7.1 systems
GoldMidi / Game port (Joystick)
A computer sound card is an additional card that is often included in the motherboard. This computer component is not compulsory but it is useful to have as most programs use a sound card.
A sound card translates signals into sounds that can be played back(phát lại) through speakers. Many motherboards have a sound card built in making it unnecessary to have a separate sound card. A pc sound card is placed into the PCI slots of a motherboard.
A computer sound card is used by a computer for music, sounds during applications and entertainment (TV, movies and games). A typical sound card usually has four ports. The largest port is the Midi/Game port, which is used for connecting a joystick or gaming controller to. The other three ports look similar and are generally green, pink and blue.

Underneath each port will be a small engraving of what each port does. The pink port is for a microphone which can record sound to the computer. The green port is line out and this is where the speakers are connected to produce sound from the computer. The blue port is line in and this is for connecting a CD-player or cassette tape to the computer.
Remember a sound card by itself is not enough to hear sound. You will still need to purchase some computer speakers or a headphone set. If you want to make use of the microphone feature then you will need to buy a computer microphone and you should then be able to record sound to your computer. Stereo microphones and headphones at JR.com may boost your sound card output.

A sound card is an internal computer component that processes audio files in order to provide high-quality playback through computer speakers. A sound card plays voice as well as music files, and can handle various audio file formats including .wav, .mp3 and .cda to name but a few. The typical sound card has an interface available at the back of the computer with various input and output ports. The quality of the sound card and speakers both affect the overall sound quality of the computer system. Speakers plug directly into the back of the sound card.
A sound card also has a line-in port for listening to or recording from an external device such as a digital audio player. If the source device does not have a line-out port to connect to the sound card, a stereo cable can be run from the headphone jack on the source device to the line-in port on the sound card. Software configurations may be required to hear the device playing.
Another port on a sound card is the microphone port. By plugging in an external mic, one can record notes, lectures, daily personal logs, audio blogs or podcasts. For private listening, every sound card features a headphone jack, which offers the perfect way to enjoy MP3s, DVDs or other audio files without disturbing others.
A sound card typically comes with proprietary software and drivers, though standard Microsoft operating systems automatically detect and load drivers for popular cards. The software interfaces with the sound card to allow the user to set parameters and controls, and to perform checks on the hardware. It might also come with tools for recording, burning, editing or composing.
Advanced sound cards come with added versatility for audiophiles. The sound card might include a digital sound port, midi interface or Sony-Philips Digital Interface Format (SPDIF) in/out ports. Some include a front bay interface that might feature a second line-in, instrument ports for recording original music, a headphone jack with its own volume control, Firewire or other options. Having these ports at the front of the computer in a bay, rather than at the back, is highly convenient for using the computer as a personal recording studio.
Generally, more expensive sound cards come with advanced software programs for editing and recording. They also support surround sound for a high-quality audio experience. This is important to audiophiles and gamers alike.
Many motherboards today have built-in sound cards. These can be disabled in order to use a superior third-party sound card purchased and installed separately. However, a built-in soundcard is likely adequate for those less fanatic about their sound quality. Sound cards range in price from about 20 to 400 US dollars (USD). They are available everywhere computer components are sold.
