Android Question Access JPG File

[MODERN TALKING]

Hi guys,

Please guide me on how to access a picture I snapped with my phone - which is saved on the phone.

With Code.

I tried: (File.DirRootExternal, "picture1.jpg")

But this doesn't work.

Thank you guys!

you took a picture with the phone camera app and you want to access the phone gallery? or did you took the picture with your app?

 

[MODERN TALKING]

Snapped the Picture with the CameraEx App.

 

[ilan]

where have you saved the image?

 

[MODERN TALKING]

Dim filename As String = "picture1.jpg"
Dim dir As String = File.DirRootExternal

camEx.SavePictureToFile(Data, dir, filename)

 

[ilan]

do you want your image to be in the Phone gallery? this is what you mean with access your image?

 

[MODERN TALKING]

No. Want another App to access the Image.

Right now the App accesses the DirAssets. I need the SECOND APP to access this JPG snapped with FIRST APP and saved.

 

[MODERN TALKING]

SECOND APP: myOCR.ExtractFromImage(File.Combine(File.DirAssets, "picture1.jpg"), "", "scene", 20000)

But need it to get "picture1.jpg" which was SNAPPED AND SAVED by FIRST APP on the same Phone.

another app you wrote? or another app like whatsapp...

if it is an app your wrote and you know the path then just load it from that path.
you saved your image to DirRootExternal so load it from there like this:

Dim bmp As Bitmap
bmp.Initialize(File.DirRootExternal,"picture1.jpg")
Activity.SetBackgroundImage(bmp)

if you want other apps to find it on the phone gallery you can use this code (put it after you save your image):

Dim i As Intent
i.Initialize("android.intent.action.MEDIA_SCANNER_SCAN_FILE", _
"file://" & File.Combine(File.DirRootExternal, "picture1.jpg"))
Dim p As Phone
p.SendBroadcastIntent(i)

Thank you Ilan,

But I tried this: myOCR.ExtractFromImage(File.Combine(File.DirRootExternal, "picture1.jpg"),"", "scene", 20000)

and it didn't work.

 

[ilan]

check if the file exists with if file.exists(...) then log("exists")
if it does not exists then something is wrong when you save the file.

 

[MODERN TALKING]

File exists. I can click on it.

Nevermind - I try to figure it out by searching in old posts.

THANK YOU VERY MUCH Ilan

what object is myOCR?

 

[MODERN TALKING]

I don't know what you mean by "object"

 

[ilan]

when you say you want to access the jpg file what do you mean?
do you want to show it on an imageview? or use it in a different way?

can you post the code when you try to load the image to the control you want to?
explain more what the app is doing with the image

 

[ilan]

to what library belongs myOCR?

 

[MODERN TALKING]

Optical Character Recognition (OCR)

Get the TEXT from the JPEG.

Sub Activity_Create(FirstTime As Boolean)
myOCR.Initialize(Me, "myOCR", "0451729a-3d4e-4ef5-9bc3-2b3c1ccd60e0")

ProgressDialogShow("WORKING")

'myOCR.ExtractFromImage(File.Combine(File.DirAssets, "picture1.jpg"), "", "scene", 20000)
myOCR.ExtractFromImage(File.Combine(File.DirRootExternal, "picture1.jpg"),"", "scene", 20000)

End Sub

 

[MODERN TALKING]

OCR (version 1.20) Library

 

[ilan]

is it working from File.DirAssets?

 

[MODERN TALKING]

YES - this is what is confusing.
