Android Question android.media.action.IMAGE_CAPTURE and targetSdkVersion="26"

[Semen Matusovskiy]

Hi, guys --

Just found Erel's CameraIntent - https://www.b4x.com/android/forum/threads/intent-based-camera.69215/

Original code works in Oreo emulator. But if to change targetSDKVersion to 26, appears

(FileUriExposedException) android.os.FileUriExposedException: file:///storage/emulated/0/Android/data/b4a.example/files/tempimage.jpg exposed beyond app through ClipData.Item.getUri()

Is it possible to fix a problem somehow ?

Especially

- 24 - must use FileProvider when sharing files (https://www.b4x.com/android/forum/t...om-your-app-with-file-provider.70458/#content)

CameraIntent was updated with the required changes.

Great. Many thanx. Works fine under Oreo. But now there are problems in old Android releases.
https://developer.android.com/reference/android/support/v4/content/FileProvider.html talks - added in version 22.1.0
As I understand, it's necessary to use previous code for SDK < 23. Correct ?

And another question. The emulator rotates a photo. Meanwhile on native smartphones I don't see similar trouble. This is emulator's bug or it's necessary to check something ?

No. This is the support library version. It will work on Android 4.0+.

And another question.

This is not the correct place to post another question.

New release doesn't work on my Samsung S4 (Android 4.4) and API 19 emulator (Unfortunately, Camera has stopped). Probably a problem not in FileProvider
Meanwhile, works in API 21 emulator

You need to test it on a real device. If it fails then post the error message from the logs.

Erel --
Like I wrote before, I tested on physical smartphone also (Samsung Galaxy S4 with Android 4.4)
Old release works, new release gives an error. But the error is inside Camera application, so there is no log.

Probably, old applications are not "FileProvider"-ready.

 

[Erel]

It is possible that the camera app doesn't work properly with non-file uris.

You can combine both options. Pass a file uri to old devices and pass a FileProvider uri to new devices.

Thanx, Erel. I did exactly so. The difference in one fragment only. Instead of

 i.PutExtra("output", CreateFileProviderUri(imageFolder, tempImageFile)) 'the image will be saved to this path

shoud be

 If SdkVersion >= 23 Then
        i.PutExtra("output", CreateFileProviderUri(imageFolder, tempImageFile)) 'the image will be saved to this path
Else
        uri.Parse("file://" & File.Combine(imageFolder, tempImageFile))
        i.PutExtra("output", uri) 'the image will be saved to this path
End If
