推荐答案

我遇到了同样的问题，并且能够解决. 当活动" 未处于恢复状态时，当您尝试调用NFC光束时会发生这种情况.

I have come across the same issue and was able to resolve. This happens when you try to invoke NFC beam, when Activity is not in Resumed State.

NFCBeamShareData检查当前活动是否处于恢复状态.如果当前活动未处于恢复状态，它将返回null对象并导致 NullPointerException 或 DeadObjectException .

NFCBeamShareData checks if the current activity is in resume state. If the current activity is not in resume state, it will return null object and causes NullPointerException or DeadObjectException.
