Android-用我的背景图片使应用程序崩溃编辑：我的解决方案

Question

the image size is 4 Mb, it's a jpg. I haven't any problem if i try to change the background with another sample image (with a smaller size , for example the ic_launcher sample).

Should be a problem with a size? 2667 × 4733 it's the image dimension.

I use a samsung s4 mini for debug, it may be useful.

this is the code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:columnCount="1"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:background="@drawable/mioartista"    
    tools:context="com.example.settingavatar.MyAvatar" >

    <!-- other things -->

</RelativeLayout>

this is the error log

EDIT : the solution that i adopted:

I changed the dimension. i make 5 set of image ( for the drawable folders) for every screen density. " is not useful use a 4mb's image if the device use at least the 50% of the size".

Answer 1

You said your image has the size of 2667 x 4733 pixels. Since this image will be turned into a Bitmap when being displayed, this is too large (in terms of pixels) and will cause your device to run out of memory.

A 32bit Bitmap of that size will use up 50 MB of RAM.

I recommend to reduce the size of the image drastically and make use of the different resource folders for image sizes . drawable-mdpi , etc.

Also, you can take a look at this question: High resolution Image - OutOfMemoryError

It deals with handling and loading large size images properly.

Answer 2

Check name of image. You may not use the name with : uppercase, - , * , and start with number.
