我安装了Android Studio 1.0.1版.我从eclipse导入了我的项目,它运行正常.然后我删除了一个模块并将其重新导入我的Android Studio项目.gradle构建说"BUILD SUCCESSFUL",但它弹出一个带有消息的警报窗口

无法完成Gradle执行.原因:已经处理:模块:'MYMODULENAME'

我现在无法启动我的应用程序.知道我能做什么吗？

编辑: 我用以下说明解决了问题:

1. 将项目视图从Android切换到Project
2. 删除条目包括settings.gradle中的"MYMODULENAME"
3. 模块符号中的蓝色框不显示.然后,您可以在上下文菜单中删除该模块
4. 导入模块

我使用Android Lollipop SDK(21)构建我的应用程序.打开一些活动并关闭它们后,一个活动就会出现这个损坏的屏幕.它看起来像是内存错误,但这只发生在Android Lollipop设备上.在Logcat中我看不到错误.

有什么想法是什么？

我有一个在Android 5.1.1设备上运行的应用程序.该应用程序有一个webview(48.0.2564.106),每周7天,每天24小时.有时应用程序崩溃是因为chrome webview有一个未捕获的异常.最新版本的webview也有同样的崩溃.Chrome浏览器应用程序具有相同的问题,但应用程序不会崩溃并显示错误页面.

我可以为webview注册未捕获的异常处理程序,并在没有应用程序崩溃的情况下捕获崩溃吗？

这个问题还有其他解决方案吗？

添加了崩溃报告:

我认为这个问题之前有人问过，但我没有找到解决我的问题的样本或解决方案。我是 opencv 的新手，我想使用 OpenCV CameraPreview 进行纸张检测。在我的示例应用程序中，我使用带有静态初始化的 opencv 3.0.0。我了解对象识别可以通过以下步骤完成：

1. 制作输入图像 Canny
2. 模糊 Canny 图像
3. 在模糊的 Canny 图像上查找轮廓
4. 搜索矩形等
5. 绘制线条或用半透明颜色填充矩形

我的问题是现在我可以精明和模糊图像，但我不知道如何找到轮廓和矩形并用半透明颜色填充它们。

这是我当前的 onCameraFrame 函数：

@Override
public Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame inputFrame) {
    Mat input = inputFrame.rgba();
    Mat output = input.clone();
    Imgproc.Canny(input, output, 50, 50);
    Imgproc.blur(output, output,new Size(5,5));
    //Find Contours
    //Search for biggest Contour/Rectangle
    //Fill Rectangle with half transparent Color
    return output;
}

谁能帮我解决纸张检测的问题并有一个android/java的代码示例？谢谢
