[android] Android EditText Max Length

If you want to see a counter label you can use app:counterEnabled and android:maxLength, like:

<android.support.design.widget.TextInputLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:counterEnabled="true">

  <EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:maxLength="420" />

</android.support.design.widget.TextInputLayout>

DO NOT set app:counterMaxLength on TextInputLayout because it will conflict with android:maxLength resulting into the issue of invisible chars after the text hits the size limit.
