Q: Does android have any native video codecs?

A: Hardware acceleration is available for h264 at certain bitrates. (link needed with specs)

Q: Is there some kind of l10n overview?


Q: What is RGB565?

A: The file format for splash screens. You probably want to create a 320x480 image. It is unsupported by any other image software, so the only way to create one is to start with a raw rgb888 file (8-bit raw, the default format in gimp or photoshop when saving as "raw image") and run it through rgb2565. Alternatively, you can save as a png and then run this script by RyeBrye on it (assumes you have working ImageMagick as well as a compiled version of rgb2565 in your path.) If you run rgb2565 with no flags, it will create an uncompressed rgb565 file which should be exactly 307200 bytes. This file can be used for replacing the initial screen you see when you start up the phone, which is done by flashing it via fastboot (details here). If, instead, you specify the -rle flag, rgb2565 will compress the image using a simple RLE algorithm. This file can be placed in the root of your boot image and named initlogo.rle, and it will show up after the initial boot screen but before the animated android screen (details here). Do not attempt to use rle compressed files to flash the initial boot screen.

Q: Where can I report bugs?

Q: What determines the category ("Lifestyle", "Entertainment") that an app is filed under? Does the developer get to pick?


Q: Whats the price for the G1 for developers?


Q: Do the market and have anything in common?


Q: So if i put the on the sd, it will automatically load that?

A:Nope. You have to tell it to load it manually (see Forcing OTA Updates)

Q: Can I run a native app easily?


Q: how does the UI operate?


Q: Is the UI based on X-Windows?

A: No

Q: How do the 3D drivers work?


Q: Not having root sucks. Any progress on a fix?

Brandorr's working notes

  • VOIP support?
    • tauno_: brocktice, "When I talked to Cole Brodman, the CTO of T-Mobile, after the event about what would stop something like Skype from designing a program that could run on the phone, negating the need for a massive voice plan, he said he had "worked with Google" to make sure Android couldn't run VOIP.
