Question

I have some picture paths stored in a datastore and i am trying to convert them into drawables and display the in my image view, for some reason im getting a null pointer exception. Can someone please help me? Thanks

String pathName = selectedPlayer.getPicture(); 
Toast.makeText(this, pathName, Toast.LENGTH_SHORT).show();
Drawable d = Drawable.createFromPath(pathName);
imageView.setImageDrawable(d);

You must check file name is not null

then check that first if file exists or not

if(pathName!=null && pathName!="") <--CHECK FILENAME IS NOT NULL
{
    File f = new File(pathName);
    if(f.exists())  <-- CHECK FILE EXISTS OR NOT
    {
        Drawable d = Drawable.createFromPath(pathName);
        imageView.setImageDrawable(d);

    }
}

EDIT :
You have to initialize your imageview first like

imageView=(ImageView)findViewById(R.id.yourimageviewid);
