从服务开始活动花费的时间太长 [英] Start activity from service takes too long

问题描述

我有一个Service，当一个功能提供给我true时，它将启动一个新的Activity，但需要5秒钟...

I have a Service that when one function gives to me true it will start a new Activity but it takes like 5 seconds...

我已经阅读了有关 issue 的信息，并且在此示例可避免"此错误.

I've read about this issue, and I've found on StackOverflow this example to "avoid" this bug..

Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
try {
   pendingIntent.send();
} catch (PendingIntent.CanceledException e) {
   e.printStackTrace();
}

，但遗憾的是它不能更快​​地启动Activity，我不需要立即进行操作(如果可能的话最好)，但是我不想等待+5秒来启动新的Activity，您知道如何避免这种情况吗?

but sadly it doesn't start the Activity faster, I don't need to be inmmediate (better if it's possible), but I don't want to wait +5 seconds to launch the new Activity, do you knwo any trick to avoid this?

我正在使用PendingIntent，因为我发现那个说它应该解决此问题的人: 从开始活动按下HOME按钮后无需延迟5秒钟即可进行服务

I'm using PendingIntent because I've found that guy that said that it should solve this issue : Starting an activity from a service after HOME button pressed without the 5 seconds delay

如果我按back button键，它会自动启动，延迟为0，但我想按home button键.

If I press back button it launch it autommatically, 0 delay, but I'm looking pressing the home button.

推荐答案

我还没有到处评论，因此我将这种类似问题的解决方案作为答案

I cannot comment everywhere yet, so I'm putting this solution of a similar problem as an answer

经过大量挖掘，找出了问题的原因.显然 这不是错误，它是一项不允许服务或 广播接收者可以在回家后进行长达5秒钟的活动 按下按钮.没有简单的方法可以克服这个问题.

After much digging, found out the cause of the problem. Apparently it's not a bug, it is a feature which does not allow Services or BroadcastReceivers to launch activities for up to 5 seconds after home button is pressed. No easy way to overcome this.

我用添加到Windows的窗口管理器中的窗口替换了活动 正在运行的服务.这不会造成任何延迟.

I replaced the activity with a Window added to the window manager of the running service. This does not cause any delay.
