Bitmap(Compress/Drawing Canvas/Save)

i have a big trouble.

So i'm using camera API to make some photo,after that i need to add some text+rect on image and save into phone memory (internal).

I found solution like this :

1) calling api camera

2) OnActivityResult calling methods, which i converting image to bitmap,adding some text + Rectangle via Paint/Canvas(on image) and after this manipulation,saving my finished image(drawn text+rectangle) via BitmapCompress.



The problem is that Compress function load full image size into RAM memory and if ill make a few photo's,app will crash with OutOfMemoryException. My was trying to make workaround like this(worst variant) :

1)using asynchrone Compress(await mechanism)

2)when Compress is done,calling Bitmap.Recycle()



But this solution doesnt helped me. Await Compress saving photo with delay 2-3 seconds and i need to save my photo immediately (like how it doing Camera Api's).

PS Sorry for my Perfect english skills.

PPS Also have bug with text appearance(always drawing vertically,but i need horizontally).
