Whenever I call setprogress() or any of the relevant functions on a progress bar, there seems to be a memory leak,  according to the memory graph (I am using Android Studio v1.5 and my testing device is Lenovo A2010-a - Android 5.1).

For example, let's asume that the activity_main xml defines a simple horizontal progress bar. This code causes a memory leak.

package package.test;

import android.os.CountDownTimer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ProgressBar;

public class MainActivity extends AppCompatActivity {

        private ProgressBar progressBar;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_main);

                progressBar = (ProgressBar) findViewById(R.id.progressBar);


                progressBar.setMax(1000);

                CountDownTimer timer = new CountDownTimer(60*60000, 10) {
                        @Override
                        public void onTick(long millisUntilFinished) {
                                if(progressBar.getProgress() >= progressBar.getMax()) progressBar.setProgress(0);
                                progressBar.incrementProgressBy(1);
                        }

                        @Override
                        public void onFinish() {

                        }
                }
                timer.start();
        }
}

The problem is not caused by the timer, or by the update interval though: even a simple while loop will cause a spike. in the memory graph:

...
progressBar.setMax(1000);
for(int i = 0; i < 1000; i++) progressBar.setProgress(i);
...

This problem may also be able to cause a crash: on Google play I have received a crash report for Galaxy S4 Active (Android 5.0), though I have  not been unable to reproduce it, thus I am not certain that it is directly related to this particular bug.
