[Solved] COP4600 Ex 4-Remote Debugging

5/5 – (1 vote)

Often we need or want to debug software on a remote host via a network debugger. Android (and Reptilian) has a built-in remote debugging system to facilitate development at the Java and native (C/C++) layers. In this project, you will use the network debugging system to push and test a simple Android application on Reptilian. The skills learned will be used in upcoming projects. You will take screenshots of apps results. Youll submit screenshots as well your source file on Canvas.

Structure

The exercise can be completed as follows:

1. 1) Install Android Studio 2020.3.1 (or later), SDK, and NDK
2. 2) Add functionality to the skeleton GUI project provided (see specification below)
3. 3) Build and remotely test (via Android remote debugging / LLDB) application
4. 4) Submit your source file and your screenshots on Canvas.

Reptilian has remote debugging built in, but in order to connect to this system, the VM must port-forward to the local host. In the latest version of Reptilian, this forwarding is already set up for you.

Android Studio

Android Studio is set up to quickly and easily connect to the remote debugging system on Android devices. In this exercise, youll install Android Studio, the Software Development Kit (SDK), the Native Development Kit (NDK), and several tools.

You can download Android Studio from here: https://developer.android.com/studio/index.html. You do not need to install the Android Virtual Device (though you may if youd like). On the first run, youll be prompted to download and install elements of the SDK and support tools. This will take some time!

Once Android Studio starts, on the intro splash page, do the following to install the rest of the necessary software:

1. 1) Click More Actions SDK Manager
2. 2) Under SDK Platforms, add Android 9.0 (Pie)
3. 3) Under SDK Tools, add NDK and CMake.
4. 4) Click Apply to install the added software.

COP4600

Open the SDK manager

Add Android 9.0

Add NDK and CMake

To connect Android Studio to Reptilian, you will need to connect VMware to Android Studios ADB instance. Navigate to Android Studios terminal and run the following command:

$ [Path to ADB] connect [IP Address]For example, your path to ADB may look like the following:$ C:Users[Username]AppDataLocalAndroidSdkplatform-toolsadb.exe

The ADB executable can generally be found in the path to the Android SDK Location, under platform- tools.

Afterwards, your Reptilian instance will appear as a device labeled as VMWare, Inc. VMWare Virtual Platform.

Application

A skeleton Java project is provided for you to work with. We have also included a Kotlin project (a new blessed Android language), but please know that this is just for fun it is not supported, so TAs and the instructor may not be able to help you with problems. (Well try though!)

The skeleton project includes two text boxes leftText and rightText and two buttons leftButton (labelled Copy to Right) and rightButton (labelled Copy to Left).
