Can anyone tell me what exactly Camera Error 100 is?
At the time of taking picture sometimes I am getting it. It happened when I called camera.takepicutre(); and shutter and raw callback are called, but jpeg-callback is not getting called.
I just want to know what exactly Camera Error 100 is and when it is generated.
Already saw the original android camera code, but didn't find Camera Error 100 there.
And this StackOverflow answer, but couldn't find any help. Because most of the time I am able to get the picture, but sometimes I am getting this error.
After seeing the Android developer site they are saying release the camera resource and start a new one. But still didn't able to find the reason behind that?
maybe you used camera as this order
camera.stopPreview();
camera.takePicture(.....);
camera.startPreview();
but that is false.
you should use it as
camera.startPreview(); //ignore it,if you have started it.
camera.takePicture(.....);
camera.startPreview();
I have tried it,it works fine!
Camera Error 100 - "Media server died. In this case, the application must release the Camera object and instantiate a new one."

I want to capture video without showing a preview. The android docs here say this is possible, but don't explain how:
http://developer.android.com/guide/topics/media/camera.html#capture-video
Note: It is possible to use MediaRecorder without creating a camera preview first and skip the first few steps of this process. However, since users typically prefer to see a preview before starting a recording, that process is not discussed here.
what are the "first few steps" to skip?
Thank you
You misinterpret the documentation. What it really says (emphasis mine):
It is possible to use MediaRecorder without creating a camera preview first and skip the first few steps of this process. However, since users typically prefer to see a preview before starting a recording, that process is not discussed here.
In other words, you can create a preview and immediately start recording. There is no hint that MediaRecorder will let you run a hidden recording session.
Moreover, I agree with the document that the added value of not starting preview before starting recording, is negligible.
You can just skip step 5 of configuring media recorder given in the above link and preview wont be shown. But user will be interested in viewing its preview.
Even though the documentation states it is possible, most of SO answers say otherwise. Take a look at this answer (and the answers linked in it).
The work around this limitation is to create a 1 x 1 px SurfaceView and use it to display the camera preview.
I got a full camera app up and running, but I'd like to have the captured picture show on the screen before saving them (they're not going to the gallery). I've googled extensively and I can't find anything on the topic. I also have no idea how to start, so any advice or links to relevant information I didn't find would be wonderful. Thanks!
First of all, I'm assuming you are using the original Camera APIs, not Camera2. That functionality is really built into the preview capturing, so I'm assuming your code is just clearing the preview too quickly.
After calling Camera.startPreview() to render the live preview on the active surface, at some point Camera.takePicture() is called to trigger the image capture and the result is returned to the PictureCallback. As soon as the image is captured, the camera preview surface is frozen on that frame until it is restarted. So as long as you don't call Camera.startPreview() again inside of onPictureTaken() to restart that process, the SurfaceView will remain frozen on the frame you want the user to see already.
Then if they want to save, you can write the JPEG data to disk, and if not toss away the data.
I try to create an application allowing me to make video recordings. My problem is that when I use the preview of the camera, the recording is very poor of quality. And without the preview, the quality is perfect.
Can anyone explain this result?
To display the preview of the camera, I call this method : camera.setPreviewDisplay(holder);
To better explain my problem, I make screenshots of the result :
In case A, I call the method camera.setPreviewDisplay(holder);
In case B, I delete the method

I had exactly the same problem (but using back camera). I was showing the preview from the camera, but when I started recording (after using setCamera), no matter what I tried, I either ended up with really poor quality, crashing or freezing.
I explained my solution over here: https://stackoverflow.com/a/26098734/1135847
I want to develop a camera demo app using the following web page example.
http://marakana.com/forums/android/examples/39.html
After taking a photo, I want to display the captured image in the main activity. How can I do this? Thanks.
Best to use another example. I can't get this one to work. Judging by the other Camera questions in SO, I think lots of people have the same problem. But before you give up on Marakana's example completely, try moving the elements OUTSIDE the element. And include the Marko forgot.
By doing that, I got past the RuntimeException, and now get a completely different error, one I think is specific to my phone: it is trying to create a Preview with an 'invalid preview size' of 480x604. But Marko's code sets the size from the size of the preview surface created,, so the phone itself is defaulting to an invalid size for the Preview surface.
Hai to All
Anybody know about the camera Api in android.when i used this Api it displayed a black and white grids and a squre moving above it.Anyone know how to get a real time camera preview please help me with some code.

You are calling the last three lines too early. You have to wait for the surface to be prepared before calling setPreviewDisplay() and you have to wait for the surface to be sized (surfaceChanged()) before calling startPreview(). This project has what you need.
You almost got the solution for the camera part, Check the code in the real device, i hope it would be working perfect in the device, since its the view from the emulator, you will be getting "white and black grids and a square moving above it." In the real device you will be getting the preview of what you are focusing on.
You are running your app on emulator, connect android based mobile to emulator and try it or copy that file into mobile and install it and then run it.
It will definatly show camera m
