@drawable in the xml file cause the app to crash

Question

I am trying to add a background image to the activity by android:background=@drawable/.. as shown in the code below. But the problem is, when i add this line android:background="@drawable/introbackground" the app crashs, and when i delete it the app works normally.

To note: the image i use, i have resized it so that, it fits the entire screen. is this could be the problem?

XML:

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/introbackground"
android:gravity="center"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.meetingpointlocator_03"

Answer 1

Out of memory on a 121925780-byte allocation.

You app ran out of memory.

To note: the image i use, i have resized it so that, it fits the entire screen. is this could be the problem?

Yes the likely cause is this background image which needs to be scaled down. Each app is allocated a certain heap size. As of android 3.0 and above bitmap pixel data is stored in the heap. You need to scale down the image.

Out of Memory error with Bitmap

Also read Load a Scaled Down Version into Memory

Answer 2

You are getting OOM i.e out of memory and also the inflator exception at

android:background="@drawable/introbackground"

because the image introbackground is of very large size.

Solution

 Use a .jpeg light weight image insted of using .png heavy image.
