我在Service中定义了一个方法,在方法中
Intent intent = new Intent(getApplicationContext(), SmokeActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
想要开启一个Activity,这是这个Activity的设置
<activity
android:name="com.aa.safe.safehei.activities.SmokeActivity"
android:launchMode="singleInstance"
android:theme="@style/MyTheme">
</activity>
我如果在这个Activity相同亲和性的Activity的窗口之上打开,那么它就会立即被调用,但是如果我返回到桌面后再使用服务中的方法开启这个Activity,他的响应效率就很差劲,延迟3-5秒都有可能.这是为什么?

Are you monitoring the Home button to start the Activity? , there will indeed be a 5s delay. You can solve this problem with the following codeonReceive()
中调用startActivity()
Intent intent = new Intent(context, AnotherActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
try {
pendingIntent.send(); // 监听到Home键按下后立即调用startActivity启动Activity会有5s延迟
} catch (PendingIntent.CanceledException e) {
e.printStackTrace();
}

It may have something to do with your opening method, because you opened it in SingleInstance Mode, and whether your Service is a remote Service!

Can you post the code of your Service and SmokeActivity? From your description, I can’t confirm which part has the problem
