Xamarin Android - Take Picture From Camera Then Pass It To Other Activity

I am new to xamarin and I want to take a picture from the camera when I click on a button on my mainactivity and then, once the picture taken, display it in an imageView in an othe

Solution 1:

Try this:

protectedoverridevoidOnActivityResult(int requestCode, Result resultCode, Intent data)
{
    base.OnActivityResult(requestCode, resultCode, data);

    // It's a good idea that you check this before accessing the dataif (requestCode == 0 && resultCode == Result.Ok)
    { 
        //get the image bitmap from the intent extrasvar image = (Bitmap)data.Extras.Get("data");

        // you might also like to check whether image is null or not// if (image == null) do something//convert bitmap into byte arraybyte[] bitmapData;
        using (var stream = new MemoryStream())
        {
            image.Compress(Bitmap.CompressFormat.Png, 0, stream);
            bitmapData = stream.ToArray();
        }

        Intent intent = new Intent(this, typeof(AddFrais));

        intent.PutExtra("picture", bitmapData);

        StartActivity(intent);
    }
    // if you got here something bad happened...
}

Then in your second Activity:

protectedoverridevoidOnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);

    // Set our view from the "main" layout resource
    SetContentView(Resource.Layout.AddFrais);

    picturefrais = FindViewById<ImageView>(Resource.Id.ImageFrais);

    //Get image from intent as ByteArrayvar image = Intent.GetByteArrayExtra("picture");

    if (image != null)
    { 
        //Convert byte array back into bitmap
        Bitmap bitmap = BitmapFactory.DecodeByteArray(image, 0, image.Length);
        picturefrais.SetImageBitmap(bitmap);
    }
}     

As you can see your second activity code is most likely the same, I just added a validation to prevent NullReferenceException if the image is not well extracted from the intent.

Hope this helps!
