Dependency:

     implementation 'com.github.castorflex.smoothprogressbar:library:1.0.0'

XML:

In Res->color

      #ff1635
      
          @color/pocket_color_1
      

      #00ff00
      
          @color/pocket_color_stop
      

In Main:

      public class MainActivity extends AppCompatActivity{
        SmoothProgressBar smoothProgressBar;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          smoothProgressBar=findViewById(R.id.myProcessbar);
          showProcessBar();
          stopAnimation();    // call when required to stop process
        }

        public void showProcessBar(){
          smoothProgressBar.setVisibility(View.VISIBLE);
          smoothProgressBar.setIndeterminateDrawable(new SmoothProgressDrawable.Builder(getApplicationContext())
            .interpolator(new AccelerateInterpolator())
            .progressiveStart(true)
            .progressiveStopSpeed(1000)
            .build());
          smoothProgressBar.setSmoothProgressDrawableBackgroundDrawable(
          SmoothProgressBarUtils.generateDrawableWithColors(
                    getResources().getIntArray(R.array.pocket_background_colors),
                    ((SmoothProgressDrawable)  smoothProgressBar.getIndeterminateDrawable()).getStrokeWidth()));
        }

        public void stopAnimation(){
          smoothProgressBar.setSmoothProgressDrawableBackgroundDrawable(
          SmoothProgressBarUtils.generateDrawableWithColors(
                    getResources().getIntArray(R.array.pocket_background_stop),
                    ((SmoothProgressDrawable)  smoothProgressBar.getIndeterminateDrawable()).getStrokeWidth()));
          smoothProgressBar.progressiveStop();
          Handler handler=new Handler();
          handler.postDelayed(new Runnable() {
            @Override
            public void run() {
               smoothProgressBar.animate().alpha(0.0f).setDuration(6000).translationY(1000);
               smoothProgressBar.setVisibility(View.GONE);
            }
          },1000);
}

      }
