Android :: Camera / SurfaceView App Returns Icon Not Emulator Checkerboard Image

Sep 29, 2010

I'm using the android SDK in Eclipse on Linux. I've used the code at itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf to write an app to store an image captured through the camera onto SD card (there are various examples of this around). It works ok except that the image returned by the camera is not what's on the preview surface. Instead of getting the checkerboard image I expect, I get different versions of the android icon depending on which version of target I choose. If I render the image to an ImageView this is confirmed as it's the same as on the SD card.

Android :: Emulator - ERROR - User Data Image Is Used By Another Emulator

Apr 13, 2010

Finally strace gave me this:

CODE:................

And several other attempts to call "link" that also fail (sshfs does not support hard links).

Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?

Android :: Prevent Camera Capture On Handet

Jan 7, 2010

Is it possible to write an application to prevent the Android handset from storing the capture picture? My thoughts are

a. Hook onto native camera apps and monitor for camera capture (or events). Once there is a capture event, my application will be able to detect and maybe remove the capture picture

b. Continously monitor camera capture picture storage. Are there any known i/o api l can use to do this?

c. Prevent all writes to the OS. Possible?

Android :: Image Capture Intent / Activity Not Get Called

Jun 26, 2009

I start an IMAGE_CAPTURE Intent like this, and my activity's onActivityResult() get called: Intent i = new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE, null); i.putExtra("return-data", true);
startActivityForResult(i, PICK_ICON_FROM_CAMERA_ID);
But, if I start my Intent like this, the Capture Image Intent did get called, but my activity's onActivityResult() never get called:
Intent i = new Intent (android.provider.MediaStore.ACTION_IMAGE_CAPTURE, null); i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.parse("file:/" + "MyTestFile")); i.putExtra("outputFormat", Bitmap.CompressFormat.PNG.name());
startActivityForResult(i, PICK_ICON_FROM_CAMERA_ID);

Android :: Microphone Audio Capture With Emulator Is Of Very Poor Quality / Make It High?

Jun 2, 2009

As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread: http://groups.google.com/group/android-developers/browse_thread/threa...

It is working; however, the audio is extremely poor -- too staticy for our needs code...

As a comparison, here is a similar audio file captured with audacity on a PC: http://juzzam.org:9090/myAudioFile_onPC.mp3

Has anyone been able to record high quality audio with the emulator? If not, is it any better on the android dev phone?

According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR: http://developer.android.com/reference/android/media/MediaRecorder.html

Here is the Activity source: http://juzzam.org:9090/RecordMicrophone.java.txt

We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options.. we defined the sdcard in the avd manager).

Android :: Motorola Droid - QCIF Camera Preview And Capture

Jun 22, 2010

I am seeing a very annoying behavior on Motorola Droid when trying to do a simple camera preview at QCIF resolution. And I was wondering if someone experienced something similar. Is there a workaround? Am I doing something wrong?

Let me explain the situation.

Firstly, right after boot-up, using native camera application there is nothing out of ordinary, I see preview each time and it is all perfectly well for as long as needed as many times as I want.

The "interesting" behavior starts when I use the slightly modified API Demos (full app available in Android SDK, modified file is attached). My goal is to preview (and later capture) video at QCIF (176 x 144) resolution.

Using CameraPreview module in API Demos application I can start preview and capture normally only the first time - picture is clear, focused, normal colors, etc. Preview and all is nice. The second time I do preview I see a very over-exposed picture, I need to turn it away from any light source to see anything, otherwise it is all white. And even in the shadow, everything is grainy, as if picture is taken with too sensitive settings (high ISO) with too long exposure. The third time, it is the opposite - the preview and capture is way too dark. I need to point the camera directly into the light source to see even a faintest picture. Pointing out of the window does not help, it has to be straight into the lamp or sun. The effect is like taking pictures with much too low ISO setting - it is way too underexposed.

The overexposed and underexposed sessions interchange, but it is not clear-cut which one appears first. So far the prevailing pattern is that overexposed one starts first. Now surprise comes when I try using native camera application. The pattern continues! It is as if hardware or or software (camera process) got "tainted" with the QCIF. This continues until I reboot the device.

Another interesting point is that if I allow device to "rest", symptoms are much less pronounced after 10 minutes, then in 15 minutes they become barely visible. However, it all comes back after the first time I capture in QCIF. Nothing like this is visible when resolution is higher, say, CIF, VGA or similar. The problem is that, for my purposes I need it to be QCIF.

General :: Offline Website Image Capture?

Apr 16, 2013

I made a purchase online utilizing my Razr this weekend and I saved the confirmation website page in my offline saved sites on my phone. I need to print a hard copy of this receipt and when I search on the device for the site I only find a .SKIA type file at the date and time of the purchase. I am assuming that this is the offline image of my save website, but now I can't figure out how to print it.

My phone attempts to search for a WIFI printer, but I don't have one available.

Is their a way to convert the .SKIA to a .pdf and then print it from my desktop or laptop?

HTC Desire HD :: Camera - Can't Find Auto Capture

Nov 28, 2010

Got mine on Tuesday and chuffed to bits with it Have been fiddling away and even reasonably satisfied with battery life now. Lots of top tips on, have read and learnt a lot so thank you all.

On to business: This morning I wanted to take a daft self-portrait of myself (a doddle on the ol' sony erisscon). It's really tricky and I tried self timer etc... So I looked in the big manual. Page 143 and 146 describe an auto capture function - for just such an event as a daft self portrait. Only problem is I can't find it!

I'm in camera - definitely photo not video - and then menu which brings up settings. All the settings are there except that one.

Any ideas? Would be handy to know where my "auto capture" option has gone!

Android :: Capture Image In Android And Show Up In Gallery?

Oct 14, 2009

I was capturing images before that were showing up in the gallery, but now they are not and I can't figure out why. Here is my code:

ContentValues values = new ContentValues();
values.put(android.provider.MediaStore.Images.Media.IS_PRIVATE, false);
String name = "ugc_" + String.valueOf(System.currentTimeMillis());
values.put(android.provider.MediaStore.Images.Media.TITLE, name);
imageURI = getContentResolver().ins (android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

I also tried:
values.put(android.provider.MediaStore.Images.Media.IS_PRIVATE, 0);
As well as leaving out that value, but nothing seems to work now.

Android :: Streaming (live) Video And Audio From Camera Example App?

Mar 23, 2010

Where to get streaming (live) video and audio from camera example for Android? Suppose I want to create some live video streaming service app so I'll have some cool server at the back end. And I know how to do that part. Suppose I have some stand alone app for PCs now I want to go on to mobile devices. So I want to see some sample app grabing audio and video streams from Phone, Synchronizing them, encoding somehow, and sending LIVE stream to server. I need any Open-Source sample that will do this or something like this. Where can I get such one?
