解决办法

我是照着这个博客的方法解决的。
总结下就是两种方法。
1.在开启相机前进行兼容性判断
uri是照片的uri,intent是开启相机的intent

if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
    intent.setClipData(ClipData.newRawUri("", uri));
    intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION|Intent.FLAG_GRANT_READ_URI_PERMISSION);
}

2.直接给予系统相机所需要的权限
grantUriPermission("com.huawei.camera", uri, Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
