推荐答案

我甚至想从其他应用程序启动此视频观看服务

I want to start this videoview service even from other applications

除非您是编写其他应用程序的人，或者雇用其他人编写其他应用程序，否则其他应用程序都不会启动您的服务.

Unless you are the one writing those other applications, or you hire people to write those other applications, no other applications will start your service.

根据您的< intent-filter> ，我的猜测是，您认为如果另一个应用程序在 ACTION_VIEW startActivity()> Intent ，这将启动您的服务.这是不正确的. startActivity()启动一个活动.无论该服务具有什么< intent-filter> ，它都不会启动服务.

My guess, from your <intent-filter>, is that you think that if another app calls startActivity() on an ACTION_VIEW Intent, that this will start your service. This is incorrect. startActivity() starts an activity. It will not start a service, no matter what <intent-filter> that service has.
