How can i get the path after i take a picture?

Question

I want to develop app that take a picture and then store it on a ImageView like a preview image. and after i want to save the uri path to a dataBase . i know how to take a picture and how to save it on my sd Card but how can i get the specific image to save it on my database table or to create a preview on imageView real time ? here my code:

public class Add_item extends Activity

Not sure what exactly you mean but thats how you set the file path :

FileOutputStream outStream = new FileOutputStream(path + filename,true);

so in your example :

outStream = new FileOutputStream(String.format(myGeneralFolder+"/%d.jpg",(System.currentTimeMillis())));

this String.format(myGeneralFolder+"/%d.jpg" will the path I guess. so assing it to a viariable and use the variable.

go ahead and do this :

    try{    
    String currentPicPath = String.format(myGeneralFolder+"/%d.jpg",(System.currentTimeMillis()));
        ImageView i = (ImageView)findViewById(R.id.image);
        Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(currentPicPath ).getContent());
        i.setImageBitmap(bitmap);
 } catch (MalformedURLException e) {
  e.printStackTrace();
} catch (IOException e) {
  e.printStackTrace();
}

good luck

Yes this is the path . but i cant set this path on imageView. Example **String currentPicPath = String.format(myGeneralFolder+"/%d.jpg",(System.currentTimeMillis())); outStream = new FileOutputStream(currentPicPath); outStream.write(data); outStream.close(); uriImage = Uri.parse(currentPicPath); d_image_pre1.setImageURI(uriImage);** – Matan Jun 17 '14 at 14:50
you should go through debugger and step over the currentpucPath and see what is the path. what is the path when you debug it ? – Zardaloop Jun 17 '14 at 15:00

ok matt I have edited my answer. get the imageviewer by ID, then turn the URL into bitmap them assign the image view with image bitmap. This should work. – Zardaloop Jun 17 '14 at 15:38
Thank your answer ,but it still dont working. :( it is not set the imageView – Matan Jun 17 '14 at 15:59

in your code you above you are not applying what i have suggested you. Also have a look at this : http://stackoverflow.com/questions/22477508/openglrenderer-bitmap-too-large-to-be-uploaded-into-a-texture-in-android-titani – Zardaloop Jun 18 '14 at 08:48
thank you all but i fix it with that solution : " BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 2; Bitmap bm = BitmapFactory.decodeFile(pathHere, options); image.setImageBitmap(bm);" – Matan Jun 18 '14 at 11:03

You can find example with full explanation in Android documentation here http://developer.android.com/guide/topics/media/camera.html how to start camera with intent, how to listen for result and what sort of data to expect in result
