title: Progressbar not filled on API 19
body: <p>I'm building a ProgressBar dynamically at Runtime, and the Progressar is not filled on API 19 only, it works on higher APIs, the green bar that represent the percentage does not appear.</p>
  
  <p>Why it doesn't work on API 19 ?</p>
  
  <pre><code>    private ProgressBar drawProgressBar(MatiereProgression mat) {
          ProgressBar progress = new ProgressBar(mContext, null, R.style.Widget_AppCompat_ProgressBar_Horizontal);
          LinearLayout.LayoutParams progressLayout = new LinearLayout.LayoutParams(0, dpToPx(4));
          progressLayout.weight = 11;
          progressLayout.gravity = Gravity.CENTER_VERTICAL;
  
          progress.setLayoutParams(progressLayout);
          progress.setIndeterminate(false);
          progress.setMax(100);
          progress.setMinimumHeight(0);
          progress.setMinimumWidth(150);
          progress.setProgress(mat.mProgress);
          progress.setProgressDrawable(ContextCompat.getDrawable(mContext, R.drawable.progressbar));
  
          return progress;
  }
  </code></pre>
