Following the Camera 2 sample I've created simple camera class to capture the images. When it's okay with capturing both flash/non-flash images on any device with Android < 7.0, on mine Nexus 5X with Android 7.1 the same config fire the flash only once on the preview. Pre-sequences are the next:
for the preview I'm using CameraDevice.TEMPLATE_PREVIEW with AE mode set to CameraMetadata.CONTROL_AE_MODE_ON_ALWAYS_FLASH
the same I use for the capture still picture, but with CameraDevice.TEMPLATE_STILL_CAPTURE
If someone can help me with this case - I'll be really appreciated.
This is just additional information on the above issue. I wish to draw some attention to this problem!
My application takes a photo every 5 seconds. I (1) select the camera, (2) acquirer a session and then with each loop I (3) create a Capture request in which I set the Flash Mode and call the capture method on the session.
I have no issues with my Samsung SM-G550T (Android version 6.01), but I was having some issues with the Flash Mode on my Moto G4 (Android version 7.0). I got both phones to Flash, but only with this setting:
CaptureRequest.Builder requestBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE);
requestBuilder.set(CaptureRequest.FLASH_MODE, CaptureRequest.FLASH_MODE_SINGLE);
I am presently having an issue with a LG device (M210N) (Android version 7.0). Using the settings I stated above I get the device to flash just once. If I completely re-initialize the camera (as described above) the device will flash again only once.
If I add the CONTROL_AE_MODE_ON_ALWAYS_FLASH setting to the above requestBuilder, then the LG does not flash at all. So I had to remove that flag.
I have tried many different additional settings and combination for settings and none of them have eliminated this issue. I wonder how many devices are affected by this issue.

I managed to preview back & front cameras simultaneously, using Camera2 API (multiple-camera-streams-simultaneously)
It works pretty well on OnePlus 8 (pro) device BUT didn't work on others such as Samsung Galaxy A32 and OnePlus 7 (pro);
got the error: ERROR_MAX_CAMERAS_IN_USE, while trying to open the second camera.
How can I know which devices can support it ?
I understand there is HW criteria for that, but what is it ?
Thanks
Starting API 30, new methods are added to know availability as well stream configuration for concurrent cameraID that you can use.

We got many samsung user complain that our app's camera "front LED flash" cannot work normal after they upgrade to Android Oreo. But it is work normal at native camera. (so it should not hardware broken issue)
After check, we found that after upgrade to Android Oreo, we cannot get any flash capability from "getSupportedFlashModes" (camera1). We also tried camera2, but it not work either.
// Camera1
Camera.Parameters cameraParameters = mCamera.getParameters();
List<String> supportList = cameraParameters .getSupportedFlashModes();
// Camera2
mCharacteristics.get(CameraCharacteristics.FLASH_INFO_AVAILABLE);
Our app is work normal before upgrade Oreo, and it also work at non-Samsung device. Is there any think I miss? or is there any tricky way to control samsung front flash ? Thanks a lot
When I check the device camera parameter IsVideoSnapshotSupported, it is set to false despite my device seemingly supporting this functionality. This setting is used to detect if a photo can be taken while the device is recording a video. My device can natively do this, and I can successfully take a photo while recording within my app if I just ignore the IsVideoSnapshotSupported value.
I don't like the idea of blindly assuming the feature is supported by all devices using my app, but I am not able to determine why the value of this parameter is false. The only device I have tested is a Samsung Galaxy S4 running Android version 5.0.1. The application is being built using Xamarin. The app is built on API 15.
I am working on an app and using the Camera class that comes with the Android SDK. The class seems to work on my Galaxy Ace, but I've read that it doesn't work on all Android devices. Here's the function I call:
Camera camera;
camera.takePicture(shutterCallback, rawPictureCallback, jpegPictureCallback);
Sometimes OEM's customize default behavior and takePicture was introduced in API level 5. I'm also using this in one of my application and till now I haven't seen a device not supporting this.
Can you be more specific on which device it's not working?
I have developed an application, that captures image by its front camera, using a surface view. It is working fine on other phones except Sony phones.
The log cat for Sony phone says
Permission failure:com.sonyericsson.permission.CAMERA_EXTENDED
I have included this permission also, but its not working.
Thanks in advance.
This permission failure is only a warning; it may prevent using higher resolutions, though. Try 320x240 to begin with, and post more information if this attempt fails.
For those who are working with the new camera HAL introduced in API 21:
I had the same issue for my Sony Xperia Z4 Tablet. The Problem for me was, that i was configuring the flash (to light the scene) with
CaptureRequest.Builder.set(CaptureRequest.CONTROL_AE_MODE, CaptureRequest.CONTROL_AE_MODE_ON_AUTO_FLASH);
This device has no builtin flash, so after removing this it worked fine.
I got the same logcat output as you had.
