Hi all.
later many time the google made a new documentation, clear and more easy about how use the camera.
on this link u will see intent codes and one example.
https://developer.android.com/training/camera/photobasics.html
i m trying compile this intents for b4a
i m with a problem on the get thumbnail
i m using StartActivityForResult to call the camera intent take picture and later get the result (path) where is the file.
the first simple result its a thumbnail, like show on google example i made this.
Google Example
What i made
the logs is
where is the problem here?
Like on the description
i m trying convert this i.GetExtra("data") to bitmap but dont works.
i m tryied open a InputStream and i have the same problem.
what is the error here?
like show on the logs the image (thumbnail) its saved with path
content://media/external/images/media/513
but if i try load this put into a bitmap i got the same error.
ps: i m already tryed add .jpg and the error continue.
ps2: if i use Log(i.ExtrasToString) this show
Bundle[{data=android.graphics.Bitmap@f2a52b1, bitmap-data=true}]
the bitmaps is here, now i need know how take this

B4X:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(imageBitmap);
}
}What i made
B4X:
Sub ion_Event (MethodName As String, Args() As Object) As Object
If Args(0) = -1 Then ' = RESULT_OK
Dim i As Intent = Args(1)
Log(Args(1))
Log(i.HasExtra("data"))
Log(i.GetExtra("data"))
Private filename As String = i.GetData.SubString(i.GetData.LastIndexOf("/") + 1)
Private dir As String = i.GetData.SubString2(0,i.GetData.Length - filename.Length)
Log(filename)
Log(dir)
Private bm As Bitmap '= i.GetExtra("data")
Dim input As InputStream = File.OpenInput(dir, filename)
bm.Initialize2(input)
input.Close
ImageView1.Bitmap = bm
End If
Return Null
End Subthe logs is
