Android 11:图像捕获后，相机意图因方向改变而崩溃 [英] Android 11 : Camera Intent Crashes on Orientation Change After Image Capture

问题描述

我正在使用相机意图捕获图像(纵向+横向)，并将其显示在Fragment的图像视图中.

I am capturing an image (Portrait + Landscape) using camera intent and showing it in an image view in Fragment.

我已遵循以下链接中的所有说明

I had followed all instructions from the below link,

https://developer.android.com/training/camera/photobasics

该代码在Android 10之前的设备上都可以正常运行，但在Android 11设备上(尤其是三星手机)上无法正常工作.

The Code is working fine on devices till Android 10, but not working on Android 11 devices (especially Samsung Phones).

我已经尝试了所有关于Stack Overflow的解决方案.

I had tried all possible solutions on Stack Overflow.

该应用程序仅在以下情况下崩溃

The application crashes in the below scenario only,

复制步骤，

1. 用户启动Camera捕获图像
2. 旋转手机以横向模式拍摄图像.
3. 用户成功捕获图像，然后单击对勾或确定".如果以人像"模式捕获图像，则应用程序不会崩溃.

我遇到以下错误，(在Crashlytics上报道)

I am getting the below error, (reported on Crashlytics)

推荐答案

处理配置更改"通过在清单中的活动中添加 android:configChanges ="orientation" .问题是当屏幕旋转回纵向时，回到应用程序后旋转.有些电话可以处理，有些则不能.

Handle "config changes" by adding android:configChanges="orientation" in your activity in Manifest. Problem is rotation after you back to your app when screen is rotating back to portrait. Some phones can handle this, some not.
