Adobe Flex的从相机胶卷移动选择的图像或拍照重新启动应用程序 [英] Adobe Flex mobile selecting image from camera roll or taking picture restarts the application
问题描述
我有我的工作，我有与轧辊选择图像/拍照问题柔性的移动应用程序。我的应用程序没有标签，但它的一个部分包含一个标签视图导航与整个底部的标签。在这些选项卡之一，我必须将图像上传到我创建了一个Web服务的能力。然而，当我选择一个图像或拍摄照片，它弹出背出初始闪屏和应用程序重新启动。如果我使用的组件独立的（选项卡式视图导航之外）则选择没有任何问题的图像，并上传。
I have a flex mobile application that I am working on that I am having issues with selecting an image from roll/taking a picture. My application is not tabbed, however one part of it contains a Tabbed View Navigator with tabs across the bottom. Within one of those tabs, I have the ability to upload an image to a webservice that I have created. However, when I select an image or take the picture, it pops back out to the initial splash screen and the application restarts. If I use the component standalone (outside of the tabbed view navigator) it selects the image and uploads without any problem.

我已经得到了类似的行为，最近加了我的见解，<一个href="http://stackoverflow.com/questions/8512165/flashbuilder-4-5-android-camera-restarting-my-application/9037019#9037019%29">another问题。我看到的东西的发行说明，AIR 2.5有关Android的杀死你的过程中，当摄像头资源不足的可能性。
I have gotten similar behavior and recently added my insights to another question. I saw something in release notes for AIR 2.5 about the possibility of Android killing your process when the camera is low on resources.
我认为这是一个FOL至少有一段时间，我提交了错误报告（＃3099508）与Adobe。我发现，如果我关掉数据和GPS，因此降低目前正在使用的资源，我有工作的机会较大。非常令人沮丧，但我还没有看到任何解决方法。在我的应用程序，我会通过一个音符（共享对象）来检测的情况时，我$才去拍照p $ PSS按钮，然后清除它，当它返回，但如果应用程序启动与笔记集，我会提出了一个对话框，建议降低资源，这是一个AIR错误。
I think it is a FOL for at least awhile, I filed a bug report (#3099508) with Adobe. I have found if I turn off Data and GPS, so lower the resources being used currently, I have a greater chance of it working. Very frustrating, but I haven't seen any workaround. In my app, I am going to detect the situation by making a note (shared object) when I press the button before going to the camera, then clear it when it returns, but if the app starts with that note set, I will put up a dialog box advising to lower resources and this is an AIR bug.
