Avoid overdraft fees, unexpected shortages, the minimum payment treadmill, and that sinking dread when you realize you actually couldn't afford to go out.

That's what Budget is for, and it's easy. You put money into the envelopes at payday, and take it out as you spend. An envelope can represent anything — a bank account, money set aside for groceries, or the cash you're saving to buy that new Android phone off-contract. Think of a checkbook, only more flexible.

Managing money is a drag, but it doesn't have to be painful or difficult.

TL;DR : Just like every other Android project.

To compile in debug mode, run this the first time:

android update project -p .

And run this every time.

ant clean
ant debug

Making a release build is a bit harder, because you need a release key. A howto is available at https://developer.android.com/tools/publishing/app-signing.html. Here's an example for generating the key (only do this once):

android update project -p . # Unless you've already done it, of course.
keytool -genkey -keystore budget.keystore -alias budget -keyalg RSA -keysize 2048 -validity 10000
echo "key.store=budget.keystore" > ant.properties
echo "key.alias=budget" >> ant.properties

And to actually build the program:

ant clean
ant release

If you want to distribute Budget with a custom Android ROM, you'll want to build it this way. Here's an example .repo/local_manifest.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
    <remote fetch="http://github.com/" name="gh" revision="master"/>
    <project name="notriddle/budget-envelopes" path="packages/apps/budget-envelopes" remote="gh" revision="release"/>
</manifest>

This will build Budget, in release mode signed with your platform key. If you want to be able to install your own build of Budget and the one from the Play Store or F-Droid, you can define BUDGET_DEBUG while building:

BUDGET_DEBUG=1 mm
