我只是在一个活动上调用isDestroyed(),得到了这个ex:

我在一个列表中有个活动,我想遍历它并完成所有的活动:
for (Activity act : Variables.pastActivites) {
try {
Log.i("Killing: ", act.getLocalClassName());
if (!act.isDestroyed()) {
act.overridePendingTransition(0, 0);
act.finish();
}
else
{
Variables.pastActivites.remove(act);
}
} catch (Exception ex) {
Log.i("KillerAct: ", ex.toString());
}
}
我甚至可以阅读官方文档,其中有一个名为isdestroyed()的函数。
现在怎么办?
最佳答案
Activity.isDestroyed()
从api级别17开始可用。如果您的应用程序设置用于较低的api,那么您将得到Exception
。
