我想知道我怎么能清洁栈的所有previous活动（除了新建一个），但我想，在Android的API 10（安卓2.3.3）。

I would like to know how can I clean all previous activities of the stack (except the new one), but I want that in Android API 10 (Android 2.3.3).

指导下使用此回答的，我知道这不是直接可能的，因为专用的标志做的，因为API 11存在

Guided with this answer, I know it is not directly possible because the flag dedicated to do that exists since API 11.

不过，我想知道这是可能的，也许有一定的兼容性，或者如果有人有任何解决方案。

But I would like to know if this is possible maybe with some compatibility or if someone has any solution.

在此先感谢。

在办法做到这一点是要始终使用启动活动 startActivityForResult（）。当你要清洁活动堆栈的情况下有当前活动的呼叫的setResult（RESULT_CANCELED），然后调用完成（）。在所有的活动（除了你的主要还是根活动），有以下方法：

On way to do this is to always start your activities using startActivityForResult(). In the case where you want to clean the activity stack have the current activity call setResult(RESULT_CANCELED) and then call finish(). In all activities (except your main or "root" activity) have the following method:

@Override
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_CANCELED) {
        // Want to clear the activity stack so I should just go away now
        setResult(RESULT_CANCELED); // Propagate result to the previous activity
        finish();
}

这将完成所有活动在堆中。

This will finish all activities in the stack.
