In my android app I have an image slider using viewpager,which changes images every 2.5 seconds in the main activity,it works fine when I open the app,but the problem is when I jump to another Activity from the MainActivity and come back it,starts to move the images in the slides very fast,as much as I jump to another activity the sliding become more faster.please help.
This is where I have included my 3 slider images slidelist.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:id="@+id/image1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:adjustViewBounds="true"
android:layout_gravity="center"
android:src="@drawable/slidetwo"
android:scaleType="centerCrop"/>
<ImageView
android:id="@+id/image2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:adjustViewBounds="true"
android:layout_gravity="center"
android:src="@drawable/slideone"
android:scaleType="centerCrop"/>
<ImageView
android:id="@+id/image3"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:adjustViewBounds="true"
android:layout_gravity="center"

android:scaleType="centerCrop"/>
</FrameLayout>This the slider layout in content main.xml(included in activity)

<me.relex.circleindicator.CircleIndicator
android:id="@+id/indicator"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_alignParentBottom="true"/>
</RelativeLayout>The following is the adpater class

view.addView(myImageLayout, 0);
return myImageLayout;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view.equals(object);
}
}This is my MainActivity class and here I have defined the timer for the slider
