I am using a custom ripple drawable
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="@android:integer/config_shortAnimTime"
android:color="@android:color/white">
<item android:id="@android:id/mask">
<shape android:shape="rectangle" >
<solid android:color="@android:color/white" />
</shape>
</item>
</ripple>
but it crashes the app on API 19
android.content.res.Resources$NotFoundException: File res / drawable /
ripple_effect_square2.xml from drawable resource ID #0x7f02017d

What should i do to prevent crashing ?
The RippleDrawable was added in API 21, so it's not available on earlier SDKs.
You can move your drawable file to res/drawable-v21 to ensure it doesn't crash on earlier releases.
I had the same problem.
Mina Samy's answer solved my problem also.
Atef Hares asked for an alternative in older versions. What works for me is to use a selector instead of ripple
for example:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#ccffffff" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle">
<stroke android:color="@android:color/white" />
</shape>
</item>
<item android:drawable="@color/playColor" />
</selector>
where
<color name="playColor">#E8EAF6</color>
Ripple is only available from Lollipop (Android API 21). Here is an example for backwards compatibility which includes states and no default background (Transparent):
Create two drawable xml
files with the same name, one will be placed in the drawable-v21
folder, and the other in the normal drawable
folder.
drawable-v21/ripple_red_solid.xml
:
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="@android:color/red">
<item android:id="@android:id/mask">
<color android:color="@android:color/red" />
</item>
<item>
<selector>
<item android:state_selected="true">
<color android:color="@android:color/red" />
</item>
<item android:state_activated="true">
<color android:color="@android:color/red" />
</item>
<item android:state_focused="true">
<color android:color="@android:color/red" />
</item>
</selector>
</item>
</ripple>
drawable/ripple_red_solid.xml
:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true">
<shape android:shape="rectangle">
<solid android:color="@android:color/red" />
</shape>
</item>
<item android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="@android:color/red" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle">
<solid android:color="@android:color/red" />
</shape>
</item>
</selector>
And then simply use it on the view like:
<LinearLayout
...
android:background="@drawable/ripple_red_solid" />
