Re: dumb(?) book question...

[Shawn Van Every]

Hi,

There isn't a forum setup as of right now. Perhaps a Google Group would be the way to go. Do you have any thoughts about that? Actually, I just created one and am cross-posting this to that group. (http://groups.google.com/group/android-media-developers)

Not a dumb question at all. I think the issue is that it assumes an SD card is available and mounted by your device. Any chance yours is removed? (It could automatically be mounted by your computer when you connect via USB and therefore unavailable on the phone itself.)

You could try using the INTERNAL_CONTENT_URI instead which will attempt to store the image in the internal phone memory rather than the SD card.

Let me know (hopefully via the android-media-developers group) how it goes.

Best,
shawn

Hi amb,

Thanks for the repost. Were you able to resolve the issue?

I have heard (I haven't used a Droid myself) that it might automount the SD card on your computer and therefore it would be unavailable on the phone making anything that attempts to use it during that time fail.

Hi Shawn:
I tried setting the USB to "charge only", which should keep the SD
card mounted to the device and still see the problem on my Droid 2.
I also tried running on an emulator and I still get a force close.
Could this have something to do with permissions to write to the SD
card?
I'll poke around some more tonight.
Thanks for the help and the follow up!

Hmmn. It shouldn't have anything to do with permissions.

Any chance you tried it with the INTERNAL_CONTENT_URI rather than the EXTERNAL_CONTENT_URI?

I'll have to try this out on a Droid and report back.

Hi Shawn:
I made the suggested changed and tried it on the device and on the
emulator.
Here is the line (as modified):
Log.d("mediaStore","before getContentResolver...");
//imageFileUri = getContentResolver().insert(
// Media.EXTERNAL_CONTENT_URI, new ContentValues());
imageFileUri = getContentResolver().insert(
Media.INTERNAL_CONTENT_URI, new ContentValues());
Log.d("mediaStore","after getContentResolver...");
In both cases, I get the following:
02-09 13:22:09.709: DEBUG/mediaStore(4754): before
getContentResolver...

I am sorry to say that I don't know what the issue is. I can understand that the INTERNAL_CONTENT_URI doesn't work but the EXTERNAL_CONTENT_URI should work.

What version of Android is your Droid 2 running?

Attached is an updated version of the project. If you could run it and give the logcat output I would appreciate it.

[amb]

Yeah!

I tried the example you kindly posted with my existing AVD (platform
2.3 / API level 9) and I get a force close.
On my phone, it doesn't work either (error pasted below). According
to Settings>About Phone, my Android Version is 2.2 and my System
Version is 2.3.20.A955.Verizon.en.US.

Next, I made and started a new AVD with a platform =1.6 and API level
= 4. The example program you posted runs fine!

I tried two other AVDs:
Runs fine with platform = 2.1 update 1 and API level = 7
BUT, it dies with platform = 2.2 and API level = 8

So, I wonder what changed between API level 7 and API level 8???

Thanks again for all the help...
