I'm trying to use the camera in an Android app using the 1.5 API. I want the camera to flash for every picture. However, when I looked at the API for camera.parameters, the setFlashMode() method is only supported for 2.0 and higher. Yet my Cliq XT, which runs 1.5, has a flash that I can set in the menu - I take this to mean there is a way to do this for the 1.5 API, though I was unable to find it.
Does anyone know how to set the flash mode using the 1.5 API?
You can use the following code to set the flash in older versions of the API:
Parameters params = camera.getParameters();
params.set("flash-mode", "on");
camera.setParameters(params);
I just guessed on the values to send to the .set method, but I just tested it and this turns on the flash.
Does anyone know how to set the flash mode using the 1.5 API?
There is no API for that in 1.5, sorry. A device manufacturer is not limited by the public SDK and therefore can access capabilities that you, as a third-party developer, cannot.

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
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.
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`m new in Android development. I work with Android version 4.x, and it has emulated web cam with very low resolution, like 640x480.
I need to make an emulated webcam so it will work in high-def modes, like (4320x2880). In android 2.x I used variables hw.camera.maxHorizontalPixels and hw.camera.maxVerticalPixels, but it looks like they don't work any more in Android 4.x emulator of webcam.
Please assist, how to set high-def camera resolution in new emulator.
Short form: there does not appear to be an option for this today.
Long form: devices.xml, in your Android directory (e.g., ~/.android/), uses this XML schema an XML schema that I cannot find anymore. The only configurable options for the camera appear to be location (front/back), flash, and autofocus. Since devices.xml is what now controls what your emulator behaves like, it would appear that there is no equivalent to the old resolution options.
