Question

I am trying to retrieve the available camera image sizes, so I able to adjust the camera to my preferred image resolution.

To retrieve the Android camera size I’ve used the following code:

camera=Camera.open();
Parameters params = camera.getParameters();
List sizes = params.getSupportedPictureSizes();
for (int i=0;i<sizes.size();i++){
    Log.i("PictureSize", "Supported Size: " +sizes.get(i));         
}

This gives me the following output, which I am not sure how to translate into a size.

"Supported size: android.hardware.Camera$Size@65d4c50"
"Supported size: android.hardware.Camera$Size@65d4a70"
"Supported size: android.hardware.Camera$Size@3fe4e00"
"Supported size: android.hardware.Camera$Size@3fe4cd0"
"Supported size: android.hardware.Camera$Size@18f5600"
"Supported size: android.hardware.Camera$Size@13f7860"

If anyone could help me understand the output it would help me a lot, thanks!

Edit: I ended up solving my problem by doing the following:

camera=Camera.open();
Parameters params = camera.getParameters();
List sizes = params.getSupportedPictureSizes();
Camera.Size result = null;
    for (int i=0;i<sizes.size();i++){
        result = (Size) sizes.get(i);
        Log.i("PictureSize", "Supported Size. Width: " + result.width + "height : " + result.height); 
    }

Answer 1

getSupportedPictureSizes() returns a List of Camera.Size objects. Camera.Size has height and width data members that tell you the height and width of the supported picture size.

Here is a sample project that uses the related getSupportedPreviewSizes() to find the preview size with the largest area that is smaller than the SurfaceView‘s size.
