Assets

The configuration assets are in a [Google Drive folder](PUT LINK). To access them, ask via email.

The easiest way to copy them in the repo folder, is by downloading the GDrive folder and running the following:

./copy-assets.sh path-of-assets-folder

If you want to do it manually, or understand the process in order to add keys, see the following subsections.

Key stores

debug.keystore and release.keystore files need to be present in the app folder. Also the file app/keystore.properties is needed with the following inside (replace where needed):

store_password=STORE_PASSWORD
key_alias=KEY_ALIAS
key_password=KEY_PASSWORD

If you need to create them, run the following in the app folder:

keytool -genkey -v -keystore debug.keystore -alias KEY_ALIAS -keyalg RSA -keysize 2048 -validity 10000
keytool -genkey -v -keystore release.keystore -alias KEY_ALIAS -keyalg RSA -keysize 2048 -validity 10000

Generic keys file

For the following services, add the files app/src/production/res/values/keys.xml and app/src/staging/res/values/keys.xml (for each environment) with this empty content:

<?xml version="1.0" encoding="utf-8" ?>
<resources>
    <string name="SOME_SERVICE" translatable="false">SOME_SERVICE_TOKEN</string>
</resources>

Fabric

In order to use Fabric, create a file app/fabric.properties with the content (replace with the right values):

apiSecret=YOUR_BUILD_SECRET
apiKey=YOUR_API_KEY

GCM

Place the staging and production google-services.json files in app/src/staging and app/src/production respectively. These are created using [a Google app] (https://developers.google.com/mobile/add?platform=android&cntapi=gcm).

Genymotion

We recommend using Genymotion emulator.

Useful plugins

The plugins for Android Studio that we consider useful are:

.gitignore
For highlighting .gitignore files and finding unused paths in it.
<dt>Android ButterKnife Zelezny</dt>
<dd>For automatically binding views with ButterKnife.</dd>

<dt>Android Material Design Icon Generator</dt>
<dd>Used to add common icons to the projects. Icons come from the <a href="https://design.google.com/icons/">
Material Icons</a>.</dd>

<dt>BashSupport</dt>
<dd>For code highlighting in bash script files.</dd>

<dt>Fabric for Android Studio</dt>
<dd>Mainly for Crashlytics Beta releases (AFAIK it's the only way to do this). Also for viewing
crashes and other Fabric stuff.</dd>

<dt>Genymotion</dt>
<dd>For quick access to Genymotion's emulators.</dd>

<dt>Lombok Plugin</dt>
<dd>In order to avoid receiving "Cannot resolve symbol/method" errors when using Lombok.</dd>

<dt>Markdown</dt>
<dd>Markdown language support.</dd>

Design tips

You can find common color material combinations in MaterialUp, which is based on Google 500 colors. Also, [Color Hunt] (http://colorhunt.co/) can be used for general color combination inspiration.

Warning libpng warning: iCCP: Not recognizing known sRGB profile that has been edited when building an APK

This happens when unrecognised and unnecessary metadata is present in PNG files. To remove it (you need exiftool):

find . -path '*src/main/res/*' -name '*.png' -exec exiftool -overwrite_original -all= {} \;

Location problems in Genymotion

A Genymotion emulator (with Google Play Services installed) will have more problems with Location than a mobile. Getting the last known location shouldn't throw null if location is enabled. See the different answers and comments here for more info.

Check for outdated libraries

Run the following:

./gradlew dependencyUpdates

cURL

Ok2Curl is added so all network activity logs a curl command to be reproduced easily if desired.

Use Google Play Services in Genymotion

Follow this StackOverflow answer.

Asset Studio

Android Asset Studio should be used when trying to generate icons for different screen densities.
