我有问题，我整整一周都在寻找。我正在创建将照片和一些数据发送到服务器的应用程序。问题是，当我开始活动时，相机必须启动，但是，对于某些设备应用程序崩溃。我无法描述错误，因为设备在其他城市。我有LG G3和HUAWEI P7两者都可以。我认为这可能是权限有问题，但我不确定。

为什么我在onCreate（）方法中看起来可能看起来很愚蠢，这是因为我的LG G3相机正在重新开始拍照。这就是为什么我的onActivityResult（）方法看起来很奇怪。

BTW我在LoginActivity中请求存储权限，我正在创建照片文件夹。

答案 0 :(得分：0)
所以我想出了问题所在。
错误是exposed beyond app through ClipData.Item.getUri()。基本上问题出在这一行i.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);。在搜索此错误后，我在此post
