Question

as a many people i have a problem with big images too.
ok,here my code. I found on stackoverflow how to fix this using BitmapFactory.Options. But in my situations i get image not from file. Can anyone tell me how to do this with Bitmap which already created in memory ( i get this picture from camera on phone)

 public void getImageAndSend( )
  {

     Bitmap newbmp ;
         newbmp= Bitmap.createBitmap(oBmp.getWidth(), oBmp.getHeight(),oBmp.getConfig());////<----------error here
      log("widt oBmp = "+oBmp.getWidth());/// width = 2048
      log(" height oBmp = "+oBmp.getHeight());///height 1538
      //BitmapFactory.Options options = new BitmapFactory.Options(); // <----- it's possible to do it without `BitmapFactory.decodeFile(pathToFile,options) ?? 
      //options.inTempStorage = new byte[16*1024];
          Canvas canvas = new Canvas(newbmp);
          //code 
  System.gc();/// can't right understand but this line fixed this problem on emulator but not on real device   

}

please tell me how to fix my problem ? : (
On emulator im not have this error. But on real device i see this error (bitmap size exceeds VM budget)

since you are getting image from camera,get the uri of the image you capture in onActivityResult() method as follows

Uri selectedImageUri=intent.getData();
String actualPath=getRealPathFromURI(selectedImageUri);
File file=new File(actualPath);
Bitmap bitmap=decodeFile(file); //this is new bitmap which you can use for your purpose 

public String getRealPathFromURI(Uri contentUri) {
        String[] proj = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    }


private Bitmap decodeFile(File f){
        try {
            //Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(new FileInputStream(f),null,o);

            //The new size we want to scale to
            final int REQUIRED_SIZE=70;

            //Find the correct scale value. It should be the power of 2.
            int width_tmp=o.outWidth, height_tmp=o.outHeight;
            int scale=1;
            while(true){
                if(width_tmp/2<REQUIRED_SIZE || height_tmp/2<REQUIRED_SIZE)
                    break;
                width_tmp/=2;
                height_tmp/=2;
                scale*=2;
            }

            //Decode with inSampleSize
            BitmapFactory.Options o2 = new BitmapFactory.Options();
            o2.inSampleSize=scale;
            return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
        } catch (FileNotFoundException e) {}
        return null;
    }

Hope this helps.This is the very familiar problem when u deal with high quality images taken from phone.check this out too
