我创建了一个项目，旨在 Android 4.4系统 - API等级19 ，所建议的日食

I have created a project, targeting android 4.4 - API Level 19, as suggested by eclipse.

不管怎么说，在模拟器上的一切看起来很完美 - 在这里是截图：

Anyways, on the emulator everything looks perfect - here is a screenshot:

该问题来当我我真正的设备上安装 - 运行Android 4.1.2 。一切的一切都完美的，工作就像一个魅力，除背景图像。它显示一个白色的背景，喜欢的图片不存在。

The problems comes when I install it on my real device - running android 4.1.2. Everything is just perfect and working like a charm, excepting the background image. It is showing a white background, like the picture does not exists.

下面是我的xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    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=".MainActivity" 
    android:orientation="vertical"
    android:gravity="center"
    android:padding="30dp"
    android:background="@drawable/wg_blurred_backgrounds_12"
>

<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnTopJokes" 
    android:onClick="showTopJokes"   
    android:gravity="center" 
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnNewJokes" 
    android:onClick="showNewJokes" 
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnAllJokes" 
    android:onClick="showAllJokes" 
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnMyFavorites" 
    android:onClick="showFavorites" 
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnCategories" 
    android:onClick="showCategories"
    android:gravity="center"
/>

<Button
    android:layout_marginTop="10dp"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnAddNewJoke" 
    android:gravity="center"
/>

</LinearLayout>

不是机器人：背景=@可绘制/ wg_blurred_backgrounds_12 工作在Android 4.1.2

Isn't android:background="@drawable/wg_blurred_backgrounds_12 working on android 4.1.2 ?

我必须改变在premissions什么？以下是我现在有：

Do I have to change anything in the premissions? Here is what I have now:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

我知道我错过了什么非常小的，但我没能发现它作为一个初学者。

I know that I miss something really small, but I'm not able to spot it as a beginner.

推荐答案

尝试使用较低分辨率的背景。也许太大了。你可以看到在logcat中。

Try with a lower-resolution background. Maybe too big. You can see that in your logcat.
