我认为我的代码是正确的（大多数情况下），因为我尽可能地遵循Facebook SDK guide。但是，当我在ActionBar中单击微调器时，我看不到Facebook SDK中的共享对话框。什么都没发生，没有错误，什么也没有。
我的Manifest中有所需的一切（提供商和Facebook活动，我的特殊号码，也是互联网权限）。另外我读到你不再需要使用较新的SDK的墙访问权限，所以我没有在我的代码中包含它（指南也没有提到它）。我肯定必须使用Facebook SDK，而不是图像共享到Facebook黑客，因为它对我的简历很重要。我只是想在Facebook上分享一张位图照片到我的墙上。 Stack上的每个类似问题都没有帮助。
有没有使用当前Facebook SDK经验的人在我的代码中看到了什么问题？感谢。
