我已经看到了很多关于这个帖子，似乎像下面的code应该工作。我已经创建了一个SD卡的图像，并把它添加到仿真器（和正常工作）。

I have seen a lot of posts about this, and it seems like the code below should work. I have created an SD Card image and added it to the emulator (and that works fine).

Intent intent = new Intent(Intent.ACTION_PICK); intent.setType("image/*"); //intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(intent, 1);

它推出并允许用户选择图像，但是当我点击图像，一切都退出和仿真器返回到主屏幕，不回我的应用程序。我onActivityResult永远不会被调用无论是。

It does launch and allow selection of images, but when I click on an image, everything exits and the emulator returns to the home screen, not the back to my app. My onActivityResult is never called either.

我在想什么？

推荐答案

我发现我的问题。我是从一个子活动启动画廊和子活动的意图有标志FLAG_ACTIVITY_NO_HISTORY其中$ P $无法进入该活动pvented回电。

I found my issue. I was launching the gallery from a sub-activity and that sub activity Intent had the flag FLAG_ACTIVITY_NO_HISTORY which prevented the call back from going to that activity.

感谢。
