Java android FloatingActionButton API 19 doesn't see

Question

On samsung galaxy s4 mini I don't see a FloatingActionButton but on samsung galaxy s6 (API 23) I see this buttons. This is how I add this buttons :

  <android.support.design.widget.FloatingActionButton
        android:id="@+id/qick_menu_bt"
        android:layout_width="wrap_content"
        android:layout_height="55dp"
        android:layout_margin="20dp"
        android:src="@drawable/quick_menu"
        app:layout_anchor="@id/mapview"
        app:layout_anchorGravity="bottom|right|end" />


    <android.support.design.widget.FloatingActionButton
        android:id="@+id/list"
        android:layout_width="wrap_content"
        android:layout_height="55dp"
        android:layout_margin="20dp"
        android:src="@drawable/lista"
        app:layout_anchor="@id/mapview"
        app:layout_anchorGravity="bottom|left|end" />

In Android Studio Preview I see this buttons , but on phone I don't see . And this I add in build.gradle :

compile 'com.android.support:design:23.0.1'

Are you sure the positioning of these buttons are appropriate for the device you are testing on? — Kamran Ahmed, Mar 30 '17 at 06:28
It was added in api 22.2.0 therefore it is not visible in api 19. If you want to use for that you can use third party libraries — Vivek Mishra, Mar 30 '17 at 06:31
@KamranAhmed please look this is what I have in Android Studio : http://static.pokazywarka.pl/i/j/s/c65b642750789c7ae47091eb8d65c058_orig.jpg — Krzysztof Pokrywka, Mar 30 '17 at 06:32
@KrzysztofPokrywka here is your answer- http://stackoverflow.com/questions/24605116/floating-action-button-for-lower-version — Gurvinder Singh, Mar 30 '17 at 06:35
@vivek-mishra The design support library is there to provide backward compatibility down to API 9. As mentioned in the question, KrzysztofPokrywka is using it from the support library (android.support.design.widget.FloatingActionButton). It was added in design library v22.2.0, and as KrzysztofPokrywka mentioned he is using v23.0.1. — Kamran Ahmed, Mar 30 '17 at 06:55
@KamranAhmed https://developer.android.com/reference/android/support/design/widget/FloatingActionButton.html. Visit this link and from api level select 19. This class will be grayed out. — Vivek Mishra, Mar 30 '17 at 06:57
@vivek-mishra The reason for that is an app with target 19 cannot work with design library v22.2.0, it will have to target API 22+. — Kamran Ahmed, Mar 30 '17 at 06:59
@KamranAhmed Ok I got your point but ultimately to use it can't be used in with target 19 right? — Vivek Mishra, Mar 30 '17 at 07:01
The target API should be 21+ for this library to be used, as in the case of KrzysztofPokrywka's code, to use the design library of v23.0.1, the target SDK version in the gradle file should be set as 23. — Kamran Ahmed, Mar 30 '17 at 07:04
@KrzysztofPokrywka What is the theme that you are using? Is it a descendent of `Theme.AppCompat`? — Kamran Ahmed, Mar 30 '17 at 07:05
You may try changing it to `Theme.AppCompat.NoActionBar` and see if it helps. — Kamran Ahmed, Mar 30 '17 at 07:14
@VivekMishra I do what you give me in link and in my project I don't see this buttons — Krzysztof Pokrywka, Mar 30 '17 at 08:27

As mentioned in the android documentation FAB is added in API 21 and above, So you have to made it customized for API 19 but that is not the recommended way

Use this might be it will works

compile 'com.android.support:design:22.2.0'

How I can customized for API 19 ? – Krzysztof Pokrywka Mar 30 '17 at 06:45
The design support library is there to provide backward compatibility. As mentioned in the question, @KrzysztofPokrywka is using it from the support library (`android.support.design.widget.FloatingActionButton`). – Kamran Ahmed Mar 30 '17 at 06:50
So what I have to do ? – Krzysztof Pokrywka Mar 30 '17 at 06:55
