Android Lollipop not showing android:background image

Question

I have designed screen where I have used JPEG image as layout background. The complete UI screen is visible correctly in Android 8(GingerBread) to Android 19(Kitkat). The layout background is not visible in Android 20+(Lollipop)

I am using App Compatibility Library.

See the screenshot below

Emulator Android 8

Solutions already tried

1. Create another folder mipmap and copied the same image there and try to access it using @mipmap\image_background. Nothing changed.

styles.xml, there is NO folder for values-v21

 <resources xmlns:android="http://schemas.android.com/apk/res/android">

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

    -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.

        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    </style>

</resources>

login button drawable

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- On Pressed state -->
    <item android:state_pressed="true" >
        <shape>
            <solid android:color="@color/btn_login_on_press" />

        </shape>
    </item>

</selector>

EDIT 1 : Added Styles.xml and button drawables EDIT 2 : Mention usage of support library

Answer 1

Use this theme for your activity in manifest.xml

<style name="AppTheme" parent="Theme.AppCompat.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/primaryColor</item>
        <item name="colorPrimaryDark">@color/primaryColor</item>
        <item name="colorAccent">@color/primaryColor</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:textColorPrimary">@android:color/white</item>
        <item name="actionMenuTextColor">@android:color/holo_blue_dark</item>
        <item name="android:actionMenuTextColor">@android:color/holo_blue_dark</item>
        <item name="android:windowBackground">@android:color/white</item>
        <item name="android:screenOrientation">portrait</item>
    </style>

and for above API 21 use this create folder in res/values-v21 and use this below theme

<style name="AppTheme" parent="Theme.AppCompat.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/primaryColor</item>
        <item name="colorPrimaryDark">@color/primaryColor</item>
        <item name="colorAccent">@color/primaryColor</item>
        <item name="android:textColorPrimary">@android:color/white</item>
        <item name="android:navigationBarColor">@android:color/black</item>
        <item name="actionMenuTextColor">@android:color/holo_blue_dark</item>
        <item name="android:actionMenuTextColor">@android:color/holo_blue_dark</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/black</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:windowBackground">@android:color/white</item>
        <item name="android:windowContentTransitions">true</item>
        <item name="android:screenOrientation">portrait</item>
    </style>

Answer 2

Assuming that you're applying your drawable using style, you probably forgot to edit additional style in v21 folder if it exists.
