Bitmap is returning null from BitmapFactory.decodeFile(filename)

When I am calling this function there is no image in image view bitmapFactory.decodefile(filename) showing null .. please help for this. Here is my code : public Bitmap ShowImage(String imageName,String userImageName ) { File sdcard_mainDirectory = new File(Environment.getExternalStorageDirectory(),"UserImages").getAbsoluteFile(); File file = new File(sdcard_mainDirectory, userImageName).getAbsoluteFile(); if (file != null) { try { String imageInSD = "/sdcard/UserImages/"+userImageName; Bitmap bitmap = BitmapFactory.decodeFile(imageInSD); return bitmap; } catch (Exception e) { e.printStackTrace(); } } return null; }
Answer:

Why are you doing this String imageInSD = "/sdcard/UserImages/"+userImageName; I think If you get a .png file is present then just, Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath()); NOTE: Also check you have a Android supported image file is present in that location..

It's simple: your file either is not an image or image that is not supported by Android's Bitmap implementation, or you path is invalid. See documentation for http://developer.android.com/reference/android/graphics/BitmapFactory.html#decodeFile%28java.lang.String%29: Returns the resulting decoded bitmap, or null if it could not be decoded. Usually when bitmap cannot be decoded some logs are printed to logcat. Inspect them carefully.

Hi it is null because may be the image size is big and getting exception please check your log and see is there any error of outofmemory bitmap if yes then use options for that: BitmapFactory.Options options; try { String imageInSD = "/sdcard/UserImages/" + userImageName; Bitmap bitmap = BitmapFactory.decodeFile(imageInSD); return bitmap; } catch (OutOfMemoryError e) { try { options = new BitmapFactory.Options(); options.inSampleSize = 2; Bitmap bitmap = BitmapFactory.decodeFile(imageInSD, null, options); return bitmap; } catch(Exception e) { Log.e(e); } }
