我正在开发一款适用于iPhone的应用程序,它使用相机扫描条形码和拍照.当我们没有Camera访问权限且用户启用了Camera Access时,应用程序崩溃并重新打开.
你能帮我解决这个问题吗？
提前致谢.

我正在为所有Android设备开发一个应用程序.它在所有设备上运行良好,我在三星Galaxy S1,Galaxy Nexus,摩托罗拉Xoom,HTC One以及亚马逊Kindle Fire上进行了测试.它在所有设备上运行都很完美,但是当我尝试在Nexus 7上使用它时,它会崩溃并在日志中显示Out of Memory Error.我尝试System.gc();在Activity#onPause()方法中使用但是徒劳无功.应用程序中存在替代的drawable和布局.请帮我解决这个问题.此问题仅适用于Nexus 7.以下是stacktrace:
