I want to install Viber and WhatsApp on Android emulator I want to install Viber and WhatsApp on Android emulator. Kindly help me out.
If you got that .apk file downloaded in your system, you can easily install that by the following steps. 


First of all copy the .apk file to the android sdk --> 'platform-tools' directory 
To start the emulator use type the following command on your terminal

cd /path_to_android_sdk/platform-tools    // press enter

then type the following to start the emulator

emulator -avd &lt;emulator_name&gt;  // press enter


&lt;emulator_name&gt; is the name that you have given when you first created that emulator. If you don't know that name, go to eclipse and click window-->Avd and Sdk manager. On that window you can see the AVD name.

After that wait for a couple of minutes so that the emulator starts. After that, unlock the emulator:


Open another tab in terminal or open another terminal and type the following commands

cd /path_to_android_sdk/platform-tools; ls //press enter

Now you should see your application name.

adb install &lt;name_of_the_apk&gt; // press enter
./adb install &lt;name_of_the_apk&gt; // for MAC machine


After that you can see a success message.


Eventually press on the menu launcher button on the emulator where you can see your application installed. Click on the icon to launch that application.
