Android X86, React Native and the Android SDK. The goal of this assignment is to load our code into a virtual phone running in VirtualBox.
Here are some videos related to this assignment.
Native with Android SDK
Here is expo running in Android 7.1 hosted in VirtualBox:
Here is our app running in Expo on Android 7.1 hosted on VirtualBox:
Install Android X86
Android X86 is a project that lets you run Android on standard X86 computers. Perhaps you could, for instance, delete Windows and just run Android X86 instead. But we will run the Android X86 in VirtualBox.
NOTE: The sticking point here is that Android is typically designed to run on the kind ARM processors found on phones. It is not designed to run on the kind of hardware we find on our laptops or desktops. Android is an open source project, so some developers have taken that open source code and got it to run on X86 machines.
Download my version of the Android X86 Nougat (Android 7.1) build as an OVA file:
Download my ancient Android X86 6.0.3 OVA:
Double click on the downloaded file to load it into VirtualBox. Be sure to choose to Re-Initialize the MAC address. Run the Pristine Android. Once you reach the Welcome follow the steps in the wizard and log in.
The simplest way to the the Android SDK is to install Android Studio. All we really need is the Android SDK, but the raw Android SDK has only a command line interface, and Android Studio can help us debug our apps. As a result, you probably need Android Studio (or here) unless you have an old version of the SDK already installed.
Android studio comes as a zip file. Unzip it. This should create a folder called android_studio. Move it to your ~/bin directory for save keeping. Navigate to ~/bin/android-studio/bin and run studio.sh like this ./studio.sh. Create a new Android project. Choose the Android Stuff thing at the bottom. Oreo 8.1.
You probably don’t need to do this:
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386
Start the Android virtual machine. Get its IP address from the “About Tablet” section of the Settings app.
Connect to Android X86 from Pristine Lubuntu or where ever you are doing your development. You do this with **adb connect
$ adb connect 192.168.2.21 connected to 192.168.2.21:5555 charlie@rohan-elf:~/temp/footoo $ adb devices List of devices attached 192.168.2.21:5555 device
The Android SDK
Here are the commands to connect to our instance of Android X86 once you have installed and configured with (Android Studio) the SDK.
adb connect 192.168.2.34
Of coure, you have to use your Andriod X86 IP address. To confirm you are connected:
Of course, you should use Bridged Adapter for your version version of Android X86. To the get the IP, use the Phone’s menu. Its something like About tablet and then Status .
Android Studio runs fine in VirtualBox, it is the emulator it includes that will not, to my knowledge, work in VirtualBox.
|Choose **Input||Mouse Integration** from the VirtualBox menu.|
Exit the Android X86 Instance
|In the File menu of VirtualBox, choose **Close||Send the shutdown signal**. A prompt will appear in the VM. Choose to shutdown the tablet.|
Now run adb devices:
$ adb devices List of devices attached e8e5bc06 device
If you need to connect to a Virtual Instance, get its IP and:
adb connect 192.168.2.20
$ adb connect 192.168.2.20 connected to 192.168.2.20:5555 $ adb devices List of devices attached 192.168.2.20:5555 device
npm start or yarn start
Turn it in
Take a screen shot of the Android Native application you built that you are most proud of running in the Android X86 VM.
Build from ISO
There are many releases on the Android X86 site. I’ve picked out a version of Android Nougat (7.1).
You can grab either one one on that page, but perhaps this one is easiest to use:
Download the 64 bit version:
Note the underscore, not hyphen, for the application name:
npm install -g react-native-cli react-native init native_lastname react-native run-android
I thought I had this working, but…
Turn on Debugging
On your phone, go to About Device. Find the build number. Tap it seven times.
Plug in your phone and lsusb:
