K-9 Mail for Android

K-9 Mail for Android

Jesse [email protected]

Hi!

I'm Jesse

I'm a Perl Hacker

Also, I like to break things

What is “K-9”?

What is “K-9”?

Email client

For Android

Why “K-9”?

My favorite mail client

mutt

K-9

+ =

Didn't it come with a mail

client?

No Search

No “stars”

No Self-Signed Certificate Support

No BCC-Self

No IMAP IDLE

No multi-select

No keybindings

No IMAP Deletes

I almost returned my new phone

It's Open Source

I could fix it

“How hard could it be?”

It's all Java

..the last time I used Java...

I used Mosaic

Appletswere new

Internet Explorer 1.0

was brand new

Java is supposed to be

“easy” for newbies

How hard could it be?

So I got the code

git clone git://android.git.kernel.org/platform/packages/apps/Email.git

Only one change REALLY mattered

Delete from IMAP Servers

+++ b/src/com/android/email/MessagingController.java

I'm done!

Building K-9(First time)

No Makefile

It's Java

No build.xml

“Just build the whole OS”

No

10 Hours

Worked great in emulator

...but not on a real phone

For “security”

What now?

Submit the change to Android?

I tried

They hadn't yet figured out the

whole community thing

(It's gotten better)

I like to share

How to share?

Fork!

Fork the OS?!?!

What did it take to fork?

Google Code Project

What's next?

Android Developer Account

Pay $20 to become an

Android Market Publisher

Submit a web form

Wait <10s

Profit!

Oh, wait

(It's free)

Jesse,

[...]

Please inform Motorola tech of this as they have recommended your program but disavow any knowledge of how to fix it, as you are 3rd party. They did though, suggest I contact godaddy, and they did give me your email, so they weren't completely useless.

ALSO, IT WOULD BE HELPFUL IF YOU SOMEHOW HAD A PHONE NUMBER ON YOUR SITE, and an easier way to contact your tech people.

Writing end-user

software is... different

What did Google think?

Some:

But why couldn't you

submit patches?

Most:

Awesome...

...So, there's this feature I

want...
