exposed beyond app through ClipData.Item.getUri()

Android7.0调用相机时出现新的错误：

android.os.FileUriExposedException: file:///storage/emulated/0/photo.jpeg exposed beyond app through ClipData.Item.getUri()

　// android 7.0系统解决拍照的问题
        StrictMode.VmPolicy.Builder builder = new     StrictMode.VmPolicy.Builder();
        StrictMode.setVmPolicy(builder.build());
        builder.detectFileUriExposure();
