image - How to show taken picture after taking a picture in android using ImageView and avoid synchronicity problems -

hello have application using surfaceviews , show preview image of image taken , button let's user retry taking picture. problem having method picturecallback anonymous function void can't homecoming file name or id let's me grab image , display overlaying surfaceview along retry button. know how can this? picturecallback() function here:( have edited original, instead of saving file saving global variable can access later through camerahelper object)

// global variable access bitmap when photographic camera callback has finished processing. private bitmappicture;

method takes picture:

public void takethepicture(camera mcamera) { log.d("camera information","taking image within takethepicture() method"); // image callback method required take image camera.picturecallback mpicture = new camera.picturecallback() { @override public void onpicturetaken(byte[] data, photographic camera camera) { // create bitmap image can later access through other way. bitmappicture = bitmapfactory.decodebytearray(data, 0, data.length); } }; mcamera.takepicture(null,null,mpicture); }

this way of accessing image has been working problem is, returning previous image took, there synchronicity problem time of access bitmappicture variable , time when info gets saved it.

hope can help me :) thanks!

it not possible because picturecallback asynchronous (and that's why void). may take hundreds of milliseconds capture picture.

the typical solution send message handler of activity, , allow handler show image view. means takepicture(camera) method can't static, have access parent activity or handler.

android image camera save surfaceview
