Re: how to get SDCARD serial number
Actually we have support for that in android. See getFatVolumeId() in android.os.FileUtils. This requires the following kernel patch in order to work: http://android.git.kernel.org/?p=kernel/common.git;a=commitdiff;h=0cb89e58ee83afb87f57d054c787489602e4502a Mike On Thu, Jul 23, 2009 at 9:05 AM, Jean-Baptiste Queru wrote: > > I don't remember seeing an API for that, you'll need to contribute one. > > JBQ > > On Thu, Jul 23, 2009 at 5:53 AM, wang yitu wrote: >> >> Can someone tell me how to get the SDCARD serail number in android? >> very appreciating for the answer. >> >> > >> > > > > -- > Jean-Baptiste M.

Re: SystemServer permissions ..
Hi Dan, I have been investigating this, and it looks to me that changing the occurrences of mContext.checkCallingPermission to mContext.checkCallingOrSelfPermission in LocationManagerService.java will fix the problem.

Re: adb remount fails on G1 with Android 1.5 images
Hi Alan, You haven't given me enough information to answer the hypothetical question. If you have all the source code for that device then you could build your own eng build. And if there is a way to reflash the firmware on the fancy new device you could install your own eng build on it. Otherwise you would probably need to contact BrandNew Co.

Re: adb remount fails on G1 with Android 1.5 images
FYI - there are three types of builds that have varying levels of security: "user" builds are secure. there is no way to get root access to the phone (unless you count the keyboard console bug that was fixed in RC30). This is what ships for regular customers. "eng" builds are insecure - adb runs as root user, which allows you to get access to files within the /data partition, remount the /system file system read/write, etc. The eng builds are normally used for development, so it is easier to debug and replace system files with "adb remount" and "adb sync" "userdebug" builds are somewhere in between. The purpose is to run as close as possible to a user build while still allowing access for debugging. adb runs as non-root, but the "su" command is enabled so you can get a root shell. And new in cupcake is the "adb root" command, which restarts adb as root user, which basically allows you to enable the adb commands that work in the "eng" build. eng and userdebug builds also have some extra features enabled not in user builds, like the ability to attach to any Java process with DDMS or a Java debugger and saving bugreport files to the SD card by pressing a key combination. Based on what you are saying (the fact that "adb root" works), it sounds like HTC has a userdebug build on their web site.

Re: getNeighboringCellInfo()
Are you taking internal code from the telephony package and linking it directly in your application? If so, that will probably not work because your application does not have the necessary permissions required for accessing the telephony system.

Re: Phone.java phone location management
Yes, the LocationManager would be the proper way to get the information you are asking for. It is the public API for location services and already handles the IPC and permissions checking necessary for transferring this information from the phone process to an application. Unfortunately it currently does not provide the detailed cell location information you are asking for. We could add the extra cell location information to the Bundle object returned via the LocationListener.onStatusChanged() callback. If you could make a proposal of the information that should be included we could try to add it in a future release.

I'm not sure what a Phidget is, but currently there are no Java APIs for dealing with USB at the moment. We only have built-in support for USB mass storage and ADB.

Re: How to test GPS
The /etc/gps.conf file on G1 looks like: NTP_SERVER=north-america.pool.ntp.org XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin NTP_SERVER is used to specify an NTP server for time injection. The XTRA_SERVER_* entries are for a Qualcomm specific feature. All these are optional - the GPS should be able to function without the gps.conf file. (So that message should really be a warning, not an error I guess...)

Re: SD Card ID
Yes, it uses the mount point, so that would be /sdcard on android.
However, Java code should use
android.os.Environment.getExternalStorageDirectory() to avoid hard
coding the path name.

Re: SD Card ID
Yes, you can get that from android.os.FileUtils.getFatVolumeId(). The native code for this is in android_os_FileUtils.cpp But the FileUtils API is not public so this not accessible from apps built with the SDK. It also requires a kernel change that is not in the mainline Linux kernel, so if you are porting to another platform you will need to pull that code into your kernel.

Re: Would the second partition on SD card be mounted and used?
Hi Brian, mountd has not been tested with multiple partitions on the same card so there is a chance some small fixes might be necessary. But theoretically it should work if you specify the correct block devices and mount points in mountd.conf. The bigger issue is the higher level framework does not provide any support for multiple external storage devices at present.
