Installing an Application
You can use adb to copy an application from your development computer and install it on an emulator/device instance. To do so, use the install
command. With the command, you must specify the path to the .apk file that you want to install:
adb install <path_to_apk>
For more information about how to create an .apk file that you can install on an emulator/device instance, see Android Asset Packaging Tool (aapt).
Note that, if you are using the Eclipse IDE and have the ADT plugin installed, you do not need to use adb (or aapt) directly to install your application on the emulator/device. Instead, the ADT plugin handles the packaging and installation of the application for you.
