I made an XML file with following code :

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
  <shape>
    <gradient
        android:startColor="@color/mainPinkStart"
        android:endColor="@color/mainPinkEnd"
        android:angle="125" />
  </shape>
</item>
</selector>

and my main activity code is :

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

android:paddingTop="@dimen/activity_vertical_margin"

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:orientation="vertical">
<HorizontalScrollView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:overScrollMode="never"
    android:scrollbars="none"

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:orientation="horizontal"

        android:layout_alignParentTop="true"
        android:layout_alignParentStart="true">

        <ImageButton

            android:src="@drawable/home_unpressed"
            android:background="@null"
           android:id="@+id/main_imageButton_home"
            />

    </LinearLayout>
</HorizontalScrollView>
</LinearLayout>
<TextView
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:background="@drawable/main_pink_gradient"/>

<android.support.v7.widget.CardView
    xmlns:card_view="http://schemas.android.com/apk/res-auto"

    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="30dp">

</android.support.v7.widget.CardView>
</RelativeLayout>

My colors file :

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#FF4081</color>
<color name="mainPinkStart">#F44195</color>
<color name="mainPinkEnd">#EE82FA</color>
</resources>

I can't find any issue where this is occuring .... I also tried using this XML file :

<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
    android:startColor="@color/mainPinkStart"
    android:endColor="@color/mainPinkEnd"
    android:angle="125" />
</shape>

but this also didn't work and I got the same error.

Please go through the log. Issue is already specified in the log. — Sujay, Dec 29 '16 at 06:23

yes it say inflaterexception.. which part in that XML file is wrong which makes it an exception... the code that i took was working and answered on questions in StackOverflow questions only. — Ambi Tambi, Dec 29 '16 at 06:26
From log "Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #5 tag requires 'angle' attribute to be a multiple of 45". Thats it — Sujay, Dec 29 '16 at 06:29

gradient tag requires 'angle' attribute to be a multiple of 45

<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="@color/mainPinkStart"
android:endColor="@color/mainPinkEnd"
android:angle="90" />
</shape>

android:angle="125"

125 is not multiple of 45, use multiple of 45

support angle of 45,90,135,180,225,270,315,360
