[android-porting] Can I use generic/ramdisk.img for my target board?

Hi all, I'm using ARM926EJ-S target board - almost like mainstone board. When I compile android full source using only 'make' command, I can get the 3 images ramdisk.img, system.img, userdata.img under the target/.../generic directory. So can I use these 3 files for my target board? or, should

[android-porting] Re: Can I use generic/ramdisk.img for my target board?

it depends on the File system configuration of your board. ramdisk.img is the root FS with ramdisk format. system.img and data.img will be mounted under /system, /data by default. Of course, images will be built by the cross-compilers attached the Android package. ABI will ensure the system call

When you call autoFocus(), you get a callback after focus is completed with a success or fail indicator. This is where you would display your in-focus indicator in the view finder. If the user releases the shutter button, then the app does nothing. If the user presses the shutter button, you call

You should start by porting the C library, which would involve: - modifying the tools used to generate the syscalls stubs to emit MIPS assembler fragments, and the SYSCALLS.TXT input file for them - probably grab a few OpenBSD mips-related arch-specific header files for configuration purposes - re

this could be quite time consuming. if your platform is same with Aigo MID (aka Gigabyte M528 or Compal Jax10), then the 6680 uses PS/2 port (i.e., you can access it via /dev/psaux). Since IdeaCom doesn't have source code or spec available to the public, the way you can get the touch screen to wo
