我有问题从资产中获取位图

我尝试在调试模式下运行我的应用程序，当我点击播放（调用保存在资源文件夹中的图像）时，应用程序停止工作，调试器给我这些断点

SceneActivity [line: 536] - onCreate(Bundle)    
SceneActivity [line: 763] - getBitmapFromAsset(String)  
SceneActivity [line: 792] - createObjectResizerManager()    
SceneActivity [line: 796] - createObjectResizerManager()

和这些堆栈

Thread [<1> main] (Suspended (breakpoint at line 763 in SceneActivity)) 
<VM does not provide monitor information>   
SceneActivity.getBitmapFromAsset(String) line: 763  
SceneActivity.onCreate(Bundle) line: 468    
SceneActivity(Activity).performCreate(Bundle) line: 5104    
Instrumentation.callActivityOnCreate(Activity, Bundle) line: 1080   
ActivityThread.performLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 2144    
ActivityThread.handleLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 2230 
ActivityThread.access$600(ActivityThread, ActivityThread$ActivityClientRecord, Intent) line: 141    
ActivityThread$H.handleMessage(Message) line: 1234  
ActivityThread$H(Handler).dispatchMessage(Message) line: 99 
Looper.loop() line: 137 
ActivityThread.main(String[]) line: 5041    
Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]  
Method.invoke(Object, Object...) line: 511  
ZygoteInit$MethodAndArgsCaller.run() line: 793  
ZygoteInit.main(String[]) line: 560 
NativeStart.main(String[]) line: not available [native method]

这是我的代码

    /**
 * Retrieves Bitmap from Asset
 * @param strName
 * @return
 * @throws IOException
 */
    private Bitmap getBitmapFromAsset(String strName) throws IOException {
        AssetManager assetManager = getAssets();
        InputStream istr = assetManager.open(strName);
        Bitmap bitmap = BitmapFactory.decodeStream(istr);
        istr.close();
        return bitmap;
    }
/**

注意：该应用程序工作正常，直到我尝试将其导出为APK，这涉及我在SDK“安装sdk构建工具20”中进行一些更新以解决proguard的问题“无法找到引用的类org.w3c。 dom.bootstrap.DOMImplementationRegistry“
