Picking images from gallery (SD Card) on my app… ¿How to allow only max 500kb photos?

WHAT I HAVE DONE NOW: i am picking images on my app with android, and showing them on a ImageView of my layout, and sometimes i got an exception java.lang.OutOfMemoryError: bitmap size exceeds VM budget. This happens when the photos are higher than 500kb.

WHAT I NEED TO DO (AND I DONT KNOW HOW TO DO IT): then, what i want to do is to allow the user only to select photos of maximum 500kb. And if the user selects a photo Higher than 500kb, then, my app should show a toast telling the user that only can select photos of max 500kb.... ¿how to do it?

this is my code:

changeImageButton.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Intent i = new Intent(Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
                startActivityForResult(i, ACTIVITY_SELECT_IMAGE);
            }
        }); 



protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
        super.onActivityR开发者_JAVA技巧esult(requestCode, resultCode, imageReturnedIntent); 

        switch(requestCode) {
        case 1:
        {
            setResult(1);
            finish();    
        }
        case ACTIVITY_SELECT_IMAGE:
            if(resultCode == RESULT_OK){  
                Uri selectedImage = imageReturnedIntent.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};

                Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String filePath = cursor.getString(columnIndex);
                cursor.close();

                selectedPhoto = BitmapFactory.decodeFile(filePath);
                //profileImage.setImageBitmap(selectedPhoto);
                profileImage.setImageBitmap(Bitmap.createScaledBitmap(selectedPhoto, 80, 80, false));
            }
        }
    }

profileImage is a ImageView of my layout. and i use scaled butmap to resice the image to 80x80

please give me some help to do that, im searching on google and i can't find nothing

Can't you just use some standard Java to get the file size, then check against your limit?

private long getFileSize(String path) {
    File file = new File(path);
    if (file.exists() && file.isFile()) {
        return file.length();
    } else {
        return 0L;
    }
}

Why do you hate your users so much? You are asking the wrong question... you don't need to cap the file size at all. It's the decompressed image size that's the problem, and you can control that.

Use the version of BitmapFactory.decodeFile() which takes a BitmapFactory.Options parameter, and then set the inSampleSize field of the options parameter to an appropriate value (2 or 4 or something). You may even want to use inJustDecodeBounds first to work out a reasonable value.
