Making an app using ProgressDialog, and it shows up fine on JellyBean but when testing with Lollipop I only see the title and message, no progress spinner.. I am using
compile 'com.android.support:appcompat-v7:22.2.0'
Support library and AppCompatActivity
The code is:
ProgressDialog progressDialog = new ProgressDialog(AddBuddyActivity.this);
progressDialog.setMessage("Loading...");
progressDialog.setCancelable(false);
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.show();
You can see another question I posted on the same topic here.

NOTE: You can see a pseudo-duplicate of this question here. The one in the link is a little more thorough, but both have the same solution.
The answer seems to be that if a user has transitions turned off in developer options, your animations in a ProgressDialog (namely the Progress Spinner) will not show. Turn them on and restart the app and you will see the spinner!
A solution that would allow for animations with those settings turned off seems to be to make a custom dialog, which admittedly would probably look better than the default ProgressDialog.
And, as a fair warning to people attempting to abuse the ProgressDialog, heed these words from the developer documentation:
Android includes another dialog class called ProgressDialog that shows a dialog with a progress bar. However, if you need to indicate loading or indeterminate progress, you should instead follow the design guidelines for Progress & Activity and use a ProgressBar in your layout.
From this, I take that using them for long calls over the network are OK, while loading information or doing a long local process should be indicated using one of the other progress components.

I am using this in Lollipop. Let me know if it works for you. The support library I am using is android-support-v4.jar
import android.app.ProgressDialog;
ProgressDialog dialog = ProgressDialog.show(this, "Title", "Message ", true, true);//Put this where you need it
This is working fine for me on: Droid Razor M with 4.4.2 Samsung Note 4 with 5.0.1 Samsung Galaxy 6 Edge with 5.1.1
