Android Question How do I access Intent.getParcelableExtra?

[NeoTechni]

I am attempting to broadbast Bitmaps generated by one app to another.
I am doing this so all the coded needed to generate the Bitmap is not needed in the destination app, to reduce bloat. I do not want to save the Bitmaps as files cause that puts unwanted strain on the SD card

When I looked it up, Intent.getParcelableExtra will allow me to get the Bitmap from a broadcast intent, how would I use a reflection object to call that since it's not available in the StartingIntent object?

You can convert the Bitmap to an array of bytes, add it to the intent, read it in the other app and convert it back to a bitmap.

The overhead sounds like it would not be able to be used for a framerate of 10/sec

The image will need to be "serialized" in both solutions (parcelable or array of bytes). The bottle-neck will be the interprocess communication. Not converting the image to an array of bytes as it will happen in any solution.

I found the code to get the BMP from the bytearray

Sub GetBitmapFromByteArray(picBuffer() As Byte ) As Bitmap
  Try
      Dim InputStream1 As InputStream, Bitmap1 As Bitmap
      InputStream1.InitializeFromBytesArray(picBuffer, 0, picBuffer.Length)
      Bitmap1.Initialize2(InputStream1)
      InputStream1.Close
      Return Bitmap1
  Catch
      Return Null
  End Try
End Sub

How would I do the reverse?

Sub GetByteArrayFromBitmap(BMP As Bitmap) As Byte()
    Dim Output As OutputStream
    Output.InitializeToBytesArray(bmp.Width * bmp.Height )
    BMP.WriteToStream(Output, 100, "PNG")
    Return Output.ToBytesArray
End Sub

I will test this.

That worked but...

I am making a launcher, and to receive make shortcut intents, I need to be able to get the BMP out of an intent the regular way

Try this:

Dim r As Reflector
r.Target = StartingIntent
Dim bmp As Bitmap = r.RunMethod2("getParcelableExtra", <key>, "java.lang.String")
