Android Tutorial [B4X] [B4XPages] Intent based camera

This solution will not work with Android 14+. Please use the more powerful MediaChooser instead: [B4X] MediaChooser - cross platform videos and images chooser

B4A + B4i project that uses an intent in B4A and the Camera object in B4i to take a picture using the default camera app.

The B4A code depends on JpegUtils: https://www.b4x.com/android/forum/threads/11629/#content
It rotates the bitmap based on the EXIF orientation attribute.

Don't miss:
- Manifest code in B4A.
- #PListExtra in main module in B4i.

B4i code was updated to fix an issue with the top page being removed from B4XPages stack.

The change adds a line before and after the Wait For Camera_Complete call:

Dim TopPage As String = B4XPages.GetManager.GetTopPage.Id
Wait For Camera_Complete (Success As Boolean, Image As Bitmap, VideoPath As String)
B4XPages.GetManager.mStackOfPageIds.Add(TopPage) 'this is required as the page will be removed from the stack when the external camera page appears.

There was an issue in the B4A implementation. Fixed now.

Excellent project Congratulations Erel!
Could you create an example but save the photos in a database or at least save the route of the photo taken? Thank you!

The above example demonstrates taking a picture with the camera , saving it as a bitmap and setting it to ImageView. (see Button1_Click sub)

Here is some code to save that bitmap to Local SQL database and also retrieving it again (to Bitmap) .. There are many more examples available in the forum.

Imageview.bitmap 2 Blob and vice versa

I looked through the posts (for example SQL Tutorial) and even find only statements pointing to transfer a bitmap file into a byte array (Dim Buffer() As Byte = File.ReadBytes(File.DirAssets, "smiley.gif")). But this is not I am looking for. 1st I need an b4x/b4a example how to transfer layout...

This thread is specifically about a B4XPages example. All the above discussion shouldn't be done in this thread and to avoid confusion I'm deleting it.

You should never post questions in existing threads.

Project updated (B4A only):
- targetSdkVersion set to 33.
- A foreground service is started before the camera intent is sent. This prevents the OS from killing the app while it is in the background. Note that we don't need to request the new post_notifications permission for foreground notifications.
