问题
I am using an activity from a third-party library that has set android:noHistory to "true". Is it possible for me to override that value in code before I launch the activity?
Is there an opposite of "FLAG_ACTIVITY_NO_HISTORY" flag I could use with the Intent?

Add an <activity> element to your own app's manifest, with an android:name attribute identifying the activity, and with android:noHistory="false". As part of the manifest merger process, your app's android:noHistory value should override the library's android:noHistory value.
In general, overriding a library's manifest entry is a somewhat risky move, as you could break something that the library depends upon. In this particular case, it should be safe.

If set, the new activity is not kept in the history stack. As soon as the user navigates away from it, the activity is finished. This may also be set with the noHistory attribute.
If set, onActivityResult() is never invoked when the current activity starts a new activity which sets a result and finishes.
