android - Onactivityresult returning null bitmap, selecting image from device not working -


I am trying to choose a picture from all the pictures on the device. I was working this code on the last app but for some reason this will not work. A Nalpointer exception gives me an exception while trying to set the selected image to an image view, so I think the bitmap is empty. I tried many tutorials and used that code, rewritten everything, but every time the same problem occurs. I have tried many devices, running Android 4.4 and Android 4.2.2 (so this is not just a KitKat problem).

My code: 

  Public class Iconize activity expanded {Public ImageView ivMain; Linear layout topscrolls; Bitmap bitmap; Int REQUEST_CODE = 1; Frame layout flow; Reference C; @ Override Protected Zero (InstanceStat saved from bundle) {// Todo auto-generated method stub super. Connet (Saved Instantstate); setContentView (R.layout.activity_iconize); C = getApplicationContext (); Topscrolls = (linear layout) this.findViewById (R.id.ll_topscrollview); Fl = (frame layout) this.findViewById (RIDFreemelAutholder); // Some questions do not relate to this question // ///// Last reference C = getApplicationContext (); PickImageFromDevice (); } @ Override Protected Zero ontop () {// TODO Auto generated method stub super.onStop (); Println ("Stop"); } Public Zero pickImageFromDevice () intent = intent (new intention); intent.setType ("image / *"); Intent.setAction (Intent.ACTION_GET_CONTENT); Intent.addCategory (Intent.CATEGORY_OPENABLE); StartActivityForResult (intent, REQUEST_CODE); } {IfCode == REQUEST_CODE & amp; amp; resultCode == Activity.RESULT_OK} try {if (! Bitmap = null) {bitmap} to protect @Override zero onActivityResult (integer requestCode, integer resultCode, intent data) Recycle (); } InputStream stream = getContentResolver (). OpenInputStream (data.getData ()); Bitmap = bitmapfender Aodestream (stream); Stream.close (); ivMain.setImageBitmap (bitmap); } Hold (FileNotFoundException e) {e.printStackTrace (); } Hold (IOException e) {e.printStackTrace (); } Hold (NullPointerException e) {e.printStackTrace (); } Super.onActivityResult (requestCode, ResultsCode, Data); }}   
  and stacktrace:

 Where is the error where the error occurs :  
  ivMain.setImageBitmap (bitmap);   
 I think I'm really forgetting something, because it should not be difficult and I did this work on previous projects ...   <
 
 
 Are you sure that  ivMain  is started properly?
