# JazCom on Droid

Example:
# Metro + React Native Notes - Getting Started
> **Note**: Make sure you have completed the [Set Up Your Environment](https://reactnative.dev/docs/set-up-your-environment) guide before proceeding.
## To Initialize
Install `react-native`, Android Development tools, and recommended tooling for non-Expo development.
* Run `npm install`
## Step 1: Start Metro (dev live reload service)
First, you will need to run **Metro**, the JavaScript build tool for React Native.
To start the Metro dev server, run the following command from the root of your React Native project:
```sh
npm start
```
## Step 2: Build and run your app
With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:
### Android
```sh
npm run android
```
### iOS
For iOS, remember to install CocoaPods dependencies (this only needs to be run on first clone or after updating native deps).
The first time you create a new project, run the Ruby bundler to install CocoaPods itself:
```sh
bundle install
```
Then, and every time you update your native dependencies, run:
```sh
bundle exec pod install
```
For more information, please visit [CocoaPods Getting Started guide](https://guides.cocoapods.org/using/getting-started.html).
```sh
npm run ios
```
If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.
This is one way to run your app — you can also build it directly from Android Studio
## Development Issues
### `:app:installDebug FAILED`
* This [link](https://stackoverflow.com/questions/37500205/react-native-appinstalldebug-failed/54955869#54955869) suggests doing some cleaning
* `pushd android`
* `./gradlew clean`
* `popd`
* Possibly also clean/reinstall packages.
* In my case, it looks like the virtual Android device was simply hung. Force reboot or reset.
### Troubleshooting
If you're having issues getting the above steps to work, see the [Troubleshooting](https://reactnative.dev/docs/troubleshooting) page.
## To trigger debug menu
1. Either shake device or
2. `adb shell input keyevent 82`
## Generate images from largest using `res/gen-images.sh`
## Curl notes
```
curl -H "Accept: application/json" -H "Content-Type: application/json" -H "User-Agent: Dexcom Share/3.0.2.11 CFNetwork/711.2.23 Darwin/14.0.0" -X POST https://share1.dexcom.com/ShareWebServices/Services/General/LoginPublisherAccountByName -d '{"applicationId":"d8665ade-9673-4e27-9ff6-92db4ce13d13","accountName": "jazeee", "password": ""}'
curl -H "Content-Length: 0" -H "Accept: application/json" -H "User-Agent: Dexcom Share/3.0.2.11 CFNetwork/672.0.2 Darwin/14.0.0" -X POST 'https://share1.dexcom.com/ShareWebServices/Services/Publisher/ReadPublisherLatestGlucoseValues?sessionId=abc123-342&minutes=1440&maxCount=1'
```
Output like:
```
[{
"DT":"\/Date(1558231462000-0700)\/",
"ST":"\/Date(1558231462000)\/",
"Trend":"Flat",
"Value":177,
"WT":"\/Date(1558231462000)\/"
},{
"DT":"\/Date(1558231162000-0700)\/",
"ST":"\/Date(1558231162000)\/",
"Trend":"Flat",
"Value":169,
"WT":"\/Date(1558231162000)\/"
}...
DT is device, ST is server. Trends used to be numbers, like 4 is flat, 3 is up, 2 is very up, 5 is down, 6 is very down. Now are strings.
```
## Build Notes
Now: `npx react-native build-android --mode=release`
* Takes 5 minutes to build due to Expo
* `./android/app/build/outputs/bundle/release/app-release.aab`
Truly speaking you only need to run `./build.sh`
Once built, you can upload the output file to Google Play Store:
`android/app/build/outputs/bundle/release/`
You'll then need to do their release process.
### Other Install notes (Obsolete)
Will need a keystore to sign the app. (Must use new file if you forgot the pwd LoL)
`keytool -genkey -v -keystore ~/.gradle/jazcomkeystore -alias jazcomkeystore -keyalg RSA -keysize 2048 -validity 90000`
See `~/.gradle/gradle.properties` for default
```
cd android
./gradlew assembleRelease
ls -la app/build/outputs/apk/release/app-release-unsigned.apk
# Note - you will need to choose your own keystore, and key-alias.
