Uploading High res images in android

Uploading High res images in android

Hi I wanted to upload high res images to my php server.Right now i am
sending images to my server using encoded string.Problem here is i can not
upload high res image it leads me to Out of memory. My image is around 1-2
Mb large in size. Here is a snippet how i upload image to server.
String encodedPagerpath="";
if(!FILE_PAGER_PATH.equals("") &&
FILE_PAGER_PATH.length()!=0)
{
byte [] b=imageTobyteArray(FILE_PAGER_PATH,150,150);
if(b!=null)
{
encodedPagerpath=Base64.encodeToString(b,
Base64.DEFAULT);
if(encodedPagerpath==null ||
encodedPagerpath.equals("")){
encodedPagerpath="";
}
}
}
//Convert image into byte array
static byte[] imageTobyteArray(String path,int width,int height)
{ byte[] b = null ;
if(!path.equals("") || path.length()!=0)
{
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
options.inDither=true;//optional
options.inPreferredConfig=Bitmap.Config.RGB_565;//optional
Bitmap bm = BitmapFactory.decodeFile(path,options);
options.inSampleSize = calculateInSampleSize(options, width, height);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
bm=BitmapFactory.decodeFile(path,options);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 70, baos); //bm is the
bitmap object
b= baos.toByteArray();
}
return b;
}
public static int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
// Calculate ratios of height and width to requested height
and width
final int heightRatio = Math.round((float) height / (float)
reqHeight);
final int widthRatio = Math.round((float) width / (float)
reqWidth);
// Choose the smallest ratio as inSampleSize value, this will
guarantee
// a final image with both dimensions larger than or equal to the
// requested height and width.
inSampleSize = heightRatio < widthRatio ? heightRatio :
widthRatio;
}
return inSampleSize;
}
I am sending this encoded string in json object. Is there any better
approach i can go for? If i go beyond 150X150 it leads me to OOM. I want
to upload high res image file without loosing its quality.
