Hello,
I'm in Integration a GPS driver into my Android (2.1) and always get
the following error message:
"Permission denied" from:

Hello,
how it is possible to build only one libary and not the whole system?
--> like: "make libgps.so"
Is it also possible to develope a hal implementation without the
complete android build system -> NDK?
And my last question is which possibilities are there to test a new
hal implementation?

Hello,
I do not understand why I can not find the "libgps.so" at "/system/
lib" in the emulator (Eclair 2.1 with GPS support enabled).
The gps test app GPSStatus works well and receives the NMEA-Messages
via Telnet...
Does the emulator not require this libary?
Best Regards,
Andreas

This is so nice - just few seconds till the libary is built !

Hello Guys,
I have to understand is how I compile native code correctly.
My target is an ARM11-Platform and I use the following Cross-
Toolchain:
CodeSourcery: arm-none-linux-gnueabi-4.3.2 (arm-2008q3) for compiling
the kernel.
This works with no problems, when I set the make params:

Thanks guys for your advice!
But now I have another problem with native code ;-)
Accessing a shared libary by an C executable:
I have built a simple library: "libhello.so"
"hello.h"
extern void hello(void);
"hello.c"

Hi,
I have a question about the android open source project:
Android has its own boot-loader, or is it necessary to take someone
like U-Boot?

Hello Guys,
does anybody know a way to get the kernel console output?
Or need I only read from a /dev/ttySX device?
On the emulator I only found "sh", but I want tab-completion - do I
have therefore build al shell binary for the goldfish like "ash" or is
there an easier

Hello,
which are the native supported processor architecures of official

Is it an ARM with ARMv5TE or ARMv7-A instruction set - or is it just
an issue of optimization, so that generally all ARM processors >=ARM9

Hello,
I have added my own service+manager into the android framework. I'm
just in debugging, but I can't see any logcat messages which are sent
from my manager.
My manager is locatet at frameworks/base/core/java/android/os/
MyManager.java
And my test application can get an instance of it (the r
orks/base/services/java/com/android/server/SystemServer.java
For more details look at the existing Services, like HardwareService.

Hello,
I have added a new kernel module in my Android Eclair 2.1 which is
loaded in init.rc and makes a device node at /dev/mynode.
My problem is about setting the permission of this node:
If I do it by myself: "chmod 0777 /dev/mynode" the rights will be set,
till next reboot - but if I do this
started by init.rc:
service setPermission /system/bin/sh myscript.sh
oneshot
But I also would like to know why this is so a crux - does it give any
possibility to "debug" the init.rc execution without rewriting init?

I think "sSync" is for new Service-connection (by

and "mSync" is for Managers that already have a Service-connection.
Right?

Thank you Ravi!
I would like to get more background for the "vchanneld"-daemon - what

Is a "vchanneld"-daemon optional or is the "rild"-daemon alone not

"init.rc"-file is no good style -> better to outsource it...
Where can I set the "hardware-platform"-variable, which is used by
init to find the appropiate init..rc file?
Is it perhaps set in the kernel-source, and not in the android-
platform-source?

This is not the device name: "ro.product.device". You mean the .
I think this number is hardcoded in the platform sources - you can
look at the adb deamon sources: /system/core/adb,
esp. on "adb.c" from where the command "adb devices" get the serial
