Android Note: OnDestroy () bug cannot be executed immediately after the call to finish ()

The project uses the microblog SDK to return when the current activity calls the finish () but cannot immediately execute the OnDestroy (), troubleshooting the source of the problem for a long time still found. Baidu is still really able to solve through this method, make a note it. 650) this.width=650; "src=" Http://img.baidu.com/hi/jx2/j_0012.gif "alt=" J_0012.gif "/>

in the current project (android2.0), a serious bug was found. When a A, B two page is opened, at this time the current page is B., if after the call to finish () in B, although has returned to a, but B did not execute the OnDestroy () method, only on the phone after a certain button is pressed, then the B.ondestroy () will be executed. B will be completely destroyed. Another: This does not happen if you press the Back button that comes with your phone.

Therefore, if there are some operations at this time in the OnDestroy () method, then in return to a do not do the key operation, B is not destroyed in time, so do not do these operations in the method.

After the location modification, it was found that the bug was due to the android:theme= "@android: Style/theme.notitlebar" on page A in androidmanifest.xml. The B-page does not have this parameter set. After adding this setting to B, the problem is resolved.

Although the problem has been resolved, but has not been understood not set Android:theme= "@android: Style/theme.notitlebar" page, why the finish () can not immediately call OnDestroy (). It is supposed that there should be no correlation between the two.
