bitmapArray.length);
} catch (Exception e) {
e.printStackTrace();
}


return bitmap;
}


public static String bitmaptoString(Bitmap bitmap) {


// 將Bitmap轉換成字串
String string = null;
ByteArrayOutputStream bStream = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 40, bStream);
byte[] bytes = bStream.toByteArray();
string = Base64.encodeToString(bytes, Base64.DEFAULT);
return string;
