Emulator stuck on A N D R O I D

[Maciej Klimas]

I built AOSP 2.3.7 from sources for my device (htc vision) but while I want to test if it works on emulator I doesn't boot, I noticed that theres missing overlay.default.so in /system/lib/hw, is this a problem? Board use msm7x30 chip. Do I need to compile my own kernel to get overlay.default.so under /system/lib/hw? Or is it issue due to ext4 partitions that I want to use and thats why they cannot be mounted?

building at ubuntu 12.04 x64, build system works ok, I've used gcc/g++ v.4.4 and sun java6 with it.

by the way

how can I change default emulator config parameters as my devices use 800x480 resolution and has 512mb ram. When I edit file it got recreated with old parameters.

Here's terminal output for emulator:

emulator: User-config was not changed.

[Jean-Baptiste Queru]

You generally can't run device builds on the emulator:

-different kernel
-different userland libraries
-potentially different storage format (emulator uses yaffs over
emulated NAND flash)
-potentially different instruction set (not much an issue any more as
the emulator has ARMv7-A, VFPv3-D32, NEON).

At some point in the past, it was somewhat possible. to build a system
image that'd run on both device and emulator, but that required having
the userland libraries for both at the same time, using the same
filesystem, and using the lowest common denominator for the
instruction set.

That worked well on early engineering hardware, 4+ years ago (the
emulator hardware is somewhat close to one of the development devices
we used before dream), and it stretched OK for dream and sapphire. It
became tricky with sholes and passion, because they used ARMv7-A when
at the time the emulator was ARMv5TE, and impossible with crespo,
because its system partition was ext4 on eMMC.

Today, I wouldn't count on it.

Thanks for your reply.

All the reasons can match my problem here as my build uses ext4, kernel for emulator isn't same as for device, probably it doesn't have ext4 support, can use different libraries, just instruction set should be supported as I used ARMv7-a kernel-qemu image and as said emulator supports it. Well, you explained it better than I excepted, so I'll give up testing it with emulator and go straight to flashing my build and testing on device now. I was searching for solution on this but I found none so I had to ask.

Thanks again for help.
