How to install apk files on Android Emulator

   If you are new to Android and looking for a way to test some of the currently available Android applications, here is how to proceed :
First get the Android SDK and unzip it somewhere on your hard drive
Add SDK_ROOT to your system variables pointing to /tools folder under the sdk
Run the emulator
Copy the apk file to /platform-tools folder
Change directory to /platform-tools and run from commandline $adb install your_application.apk
Now check applications list in the emulator and you should see the new application installed and ready.
Some pointed me to the error message when running adb on windows : * deamon still not running * error: no device.
In this case try to shutdown adb server and start it manually using :
$adb kill-server
$adb start-server
You can test if deamon is working by running $adb shell
The uninstall procedure is
$adb shell rm your_application.apk


: In Linux


=> First we should put the .apk file in androidsdk==>platform-tools

=>run the terminal and type (key board shortcut alt+crtl+t)
1.cd[path of android platform tools]

2../adb devices

3../adb install filename.apk



now we can see the result in emulator:
