Android Tutorial Intent Based Camera

Erel · Jul 21, 2016

Newer example: [B4X] [B4XPages] Intent based camera

This example uses an intent to take a picture with the default camera app.

It is based on this tutorial: https://developer.android.com/training/camera/photobasics.html

It is simple to use and doesn't require any permission (*).

It does rely on the default camera app to work properly and save the image file in the path passed in the intent.
As a fallback, if the image was not saved it tries to get the thumbnail from the intent returned.

Don't miss the manifest editor code that is required for sharing file uris.

Is possibile add an editbox into the form where are "OK" and "Cancel" buttons ?

Erel · Nov 10, 2016

No. The camera dialog is part of a different app.

Hi Guys

This code triggers an exception when used from within a class module

B4X:

Sub GetBA As Object
   Dim jo As JavaObject
   Dim cls As String = Me
   cls = cls.SubString("class ".Length)
   jo.InitializeStatic(cls)
   Return jo.GetField("processBA")
End Sub

The same code works fine if moved to parent activity.

Is there a workaround?

Thanks in advance

Erel · Dec 25, 2016

Try it with:

B4X:

Sub GetBA As Object
 Dim jo As JavaObject = Me
 Return jo.RunMethod("getActivityBA", Null)
End Sub

I haven't tested it.

Good morning,
When i take photo and returns to main app, app starts at landscape and immediately changes to portrait. I want to use this at my app, but this behavior is not professional.
Thank you for your time.

p.s. tried on Galaxy S4

CameraIntent was updated. targetSdkVersion is set to 26 and it uses FileProvider to export the file uri for the camera output.

Pooya1 · Apr 25, 2018

Can i use this code in all android version without problem? (i would like make without any library for take picture from camera)
Problems like "cannot connect to camera","cannot save output" or any problem that it is dangerous

Erel · Apr 25, 2018

The intent based solution should work on Android 4+.

It relies on the default camera app to work as it should. We know for sure that it is not always the case.

Erel · Apr 27, 2018

The code was updated. It now creates a file:// uri for Android 6- devices and a file provider uri for Android 7+ devices.

* - It uses RuntimePermissions.GetSafeDirDefaultExternal which means that you need to add the external storage permission to older versions of Android with this manifest code:

B4X:

AddManifestText( <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="18" /> )

Is there any way to receive video from camera also?

Erel · May 27, 2018

Yes. Change the intent action from android.media.action.IMAGE_CAPTURE to android.media.action.VIDEO_CAPTURE

Hi,

I have changed the example of Erel so that the photos can now be saved under the default order "../DCIM/Camera".

it dose not work for me. (android 7.0)

how can change Erel's code such that taken picture directly save in File.DirRootExternal (for example, or in specific directory).
in the other word manifest be only write external storage and camera permission not default path.

You just have to change the "/DCIM/Camera" folder to your folder.
