→Deploy the application on the target
=== Introduction ===
This tutorial shows you how to develop your first Android application and run it on the DACU platform. You can watch the full procedure on the [] video.
=== Boot the system ===
Let's assume the system is configured to boot loading the kernel and root file system from the internal flash.
Start the system as described in the [[DacuIndustrial_Tablet#.22Normal.22_mode | Running Android in "normal mode"]] section. {{ImportantMessage|text='''The default IP address is 192.168.0.122'''}}
==== Change the default ip address ====
[[File:Dacu-serial-console-cable.jpg|thumb|none|border|350px|Dacu serial cable]]
and start your preferred terminal emulator, as described in the [[DacuIndustrial_Tablet#.22Full_control.22_mode | Running Android in "full control mode"]] section.
On the u-boot console, please enter the following command to check the default ip address:
==== Check the Android Debug Bridge (ADB) and connect to the target ====
Start a connection through the Android Debug Bridge as described in the [[DacuIndustrial_Tablet#Running_the_Android_Debug_Bridge_.28ADB.29 Running_the_Android_Debug_Bridge | Running ADB]] section. Please note that setting the correct IP address on the target and is mandatory to make ADB work.
=== Develop your first application with Eclipse ===
==== Launch the application on the emulator ====
To launch the application on the DACU emulator:
# click on "Run" on the top menù
# select "Run Configurations..."
# on the "Run Configurations" window, enter the project name and select the "do nothing" option
# click on "Run"
# after a while, the emulator will start and you'll see the Android lock screen
# drag the "lock" icon upwards to access the Android desktop
# on the right of the desktop there are three icons: click on the middle one (between the globe icon and the phone icon)
# click on the "MainActivity" icon: it will open the "Hello, world!" window.
Please refer to the following pictures:

=== Deploy the application on the target ===
To install the application on the target, please follow these steps: # close the running emulator# check that [[Industrial_Tablet#Running_the_Android_Debug_Bridge | ADB is running]]# open a shell and move to the workspace directory containing the project files (example: /home/user/workspace/MyFirstApp)# enter the bin sub-directory. If you list the content of this directory, you should see the application .apk file# Using ADB, please lauch the following command:
<pre class="workstation-terminal">
adb install <>/MyFirstApp.apk
</pre>
Now you can access the device, go to the applications screen and touch the "MainActivity" icon to run the application.
