调用startActivityForResult（）时，Android 8.1关闭活动

Question

有人来救我。我正在构建一个Android应用程序，需要从设备相机拍摄照片并将缩略图加载到ImageView中，请注意我不想保存此图像，我只想将其加载到ImageView中并从中获取位图ImageView以后。

这就是我已经实现的：启动相机：

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if(cameraIntent.resolveActivity(activityWeakReference.get().getPackageManager()) != null){
startActivityForResult(cameraIntent, UPLOAD_PICTURE_CAMERA);
}

下面是调用onActivityResult(int requestCode, int resultCode, Intent data)时调用的startActivityForResult()：

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK && requestCode == UPLOAD_PICTURE_CAMERA) {
try{
                    Bundle extras = data.getExtras();
                    Bitmap imageBitmap = (Bitmap) extras.get("data");
                    imageViewphoto.setImageBitmap(imageBitmap);

                }catch (Exception e){
                    Log.e(TAG, Utility.stringify(e));
                }
}

问题：上面的代码适用于Android 7.0，但在Oreo 8.1上，活动立即关闭Camera打开，因此不调用onActivityResult()。

这是我可以得到的所有日志：

I/PhoneWindow: isNeedChangeStatusBarColor taskInfo: [android.app.ActivityManager$RunningTaskInfo@c7a24ee] size: 1
    isAPPNeedChangeSBColor pkgName: com.a3lineng.softwaredev.freedom_app needKeep: false

谁在Oreo面临同样的问题？，任何建议都将受到赞赏。

我已经能够在我的情况下解决这个问题，我发现它是在设备上启用的名为Kill Background Activities的用户设置。我所做的只是取消选中它，并且调用活动可用于从Camera意图接收结果。

谢谢你的帮助。
