The method of the class is like this:

InputStream photo_stream = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(), my_contact_Uri, true);
BufferedInputStream buf = new BufferedInputStream(photo_stream);
bitmap = BitmapFactory.decodeStream(buf);
try {

The issue has been found on phones running Android 4.4. In many other cases, the method works fine on other operating system versions.
Solution
For anyone who still has such error issues, here’s my conclusion :
After a lot of searching and trying everything I could find online, I fixed it myself. I used DDMS to look at the threads currently running on my device and found that there was an ASyncTask that ran for a long time and never stopped.
It appears to be accessing “something” that the main thread is accessing, and after accessing that “something” for some time, two threads collide causing the application to hang, resulting in an ANR exception.
What I did was remove ASyncTask and instead do this “one-off” operation at the start of the application (when it starts) to ensure it only runs once and not again.
I really recommend using DDMS to see the current thread, as ANRs are often caused by synchronization/concurrency issues. ANR p>
If you receive this error, please feel free to contact me privately.
