Display image with pinch zoom

Hi, Im writing an application that will take pictures and then review these.

I have two problems.

1) The preview picture (using your demo code) before capturing is always in the wrong orientation, any idea how I can get the preview to match with the camera (on my Samsung galaxy S II) ?

B4X:

   cameraRear.StartPreview

2) After capture, how can I display as a full screen picture with pinch zoom capability (so the used can review the quality of the picture before sending it off) ?

I tried webview but couldn't get the picture to load ?!?

B4X:

   viewPicture.LoadHtml("<html><body><img src='file:///" & File.DirRootExternal & "test.jpg' width='100%' height='100%'/></body></html>")

The official camera library only supports landscape orientation. You can try the AdvancedCamera library: Basic4android Search: camera library

You are building the file URL string incorrectly.
Write:

B4X:

Log("'file:///" & File.DirRootExternal & "test.jpg'")

And see what you get.
