change button color cause application crash
I want to change the button color so I used the following selector 

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    
        <item android:state_focused="true" android:color="#FFFF00"/>
        <item android:state_pressed="true" android:color="#FFFF00"/>
    
        <item>
            <shape>
                <gradient android:startColor="#ff00ff00" android:endColor="#bb00ff00" android:angle="270" />
                <stroke android:width="1dp" android:color="#bb00ff00" />
                <corners android:radius="3dp" />
                <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
            </shape>
        </item>
    
    </selector>

and use it like this 

    <Button
        android:id="@+id/SODEOD"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="SOD/EOD" 
        android:background="@drawable/firstbuttoncolorstyle" 
        />

but this cause the application to crash

I want to change the button color so I used the following selector 

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    
        <item android:state_focused="true" android:color="#FFFF00"/>
        <item android:state_pressed="true" android:color="#FFFF00"/>
    
        <item>
            <shape>
                <gradient android:startColor="#ff00ff00" android:endColor="#bb00ff00" android:angle="270" />
                <stroke android:width="1dp" android:color="#bb00ff00" />
                <corners android:radius="3dp" />
                <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
            </shape>
        </item>
    
    </selector>

and use it like this 

    <Button
