# lbry-android development environment inside docker
[scripts/lbry-android.sh](scripts/lbry-android.sh) is a bash script to create a
docker container for lbry-android development.
This is a hybrid approach where the apk is built inside docker, but you run
Android Studio, `adb`, and the app hot-reload bundler, directly on your host.
## Features
* Clones lbry-android source code to a directory on the host, and mounts it
inside the container.
* Installs all build dependencies inside the container, leaving your host
computer clean.
* Mounted `.buildozer` directory to save container space. (Docker containers
should stay under 10GB, and `.buildozer` is too big, so it has to stay in a
mounted host directory instead.)
* The biggest downloads are cached in `.buildozer-downloads` directory so you
can easily remove `.buildozer` and not have to re-download the large cryostax
NDK more than once.
* Instructions for installing on a real Android device, and for setting up
hot-reload.
* Only a handful of commands to go from zero->hero.
## Requirements
Install all of the following on your host computer:
* Tested on Linux x86_64 with BASH.
* [Install Android Studio](https://developer.android.com/studio/).
* The normal install auto-creates a directory in `$HOME/Android/Sdk` to store
SDK downloads in your home directory.
* [Install nodejs](https://nodejs.org/en/download/package-manager/).
* [Install yarn](https://yarnpkg.com/lang/en/docs/install).
* [Install Docker](https://docs.docker.com/install/).
* Install `sudo` and give your user account access to run `sudo docker`.
## Install
Clone `lbry-android`:
```
LBRY_GIT=$HOME/git/vendor/lbryio/
mkdir -p $LBRY_GIT
git clone https://github.com/lbryio/lbry-android.git $LBRY_GIT
cd $LBRY_GIT/lbry-android
```
Install a bash alias to the [scripts/lbry-android.sh](scripts/lbry-android.sh)
script:
```
echo "alias lbry-android=$LBRY_GIT/lbry-android/scripts/lbry-android.sh" >> $HOME/.bashrc
source ~/.bashrc
```
## Usage
* First create the base docker image:
```
lbry-android docker-build
```
(If anytime you change the docker build scripts in the [scripts](scripts)
subdirectory, you should rebuild the image again.)
* Setup buildozer and install dependencies:
```
lbry-android setup
```
* Build the apk:
```
lbry-android build
```
The apk will be built and end up in the `lbry-android/bin/` subdirectory.
## Running on a real Android device
Once you have the apk built, you can install it on a real Android device to
start testing.
Follow the Android documentation for [enabling USB
debugging](https://developer.android.com/studio/command-line/adb#Enabling) on
your device.
Once you have enabled debugging, do the following:
* Plug your device into a USB port on the host computer.
* Run:
```~/Android/Sdk/platform-tools/adb devices```
* ADB should list your device like so:
```
[ryan@t440s lbry-android]$ adb devices
List of devices attached
HT71R0000000 device
```
* The first time you connect, you should see a modal dialog on the device
asking to confirm the host id. You must approve it, or adb will fail to
connect.
* If after trying several times, adb is still not connecting to your device,
and adb lists your device as `unauthorized`, you may need to [follow this
advice](https://stackoverflow.com/a/38380384/56560) and delete your
`$HOME/.android` directory.
* Install the apk (whatever the current version is called) to the device:
```
~/Android/Sdk/platform-tools/adb install ./bin/browser-0.7.5-debug.apk
```
* Open the app on your device, and follow the initial steps to get to the main
lbry-android browser page.
* Create a tcp tunnel over the adb bridge, for the app to handle live-reload:
```
~/Android/Sdk/platform-tools/adb reverse tcp:8081 tcp:8081
```
* Start the live-reload server on the host:
```
cd app/
yarn install
yarn start
```
* With your device currently running the lbry-android app, shake the device
from side to side, and a menu will appear. Choose `Enable Hot Reloading`.
* The app should reload itself.
* Now make a change to the source code to test hot reload. From the host, open
up the main page view source code: `app/src/component/uriBar/view.js`. Find
the line that reads `Search movies, music, and more` (This is the main search
bar at the top of the app.) - Change some of the text and save the file.
* If hot-reload is working, within a few seconds the phone should reload the
page automatically and show the change that you made.
* If the hot-reload does not work, try closing the app (dismiss the window from
the tab overview, via android square button) and reload the app.
