问题 My Problem: When openFile() intent attempts StartActivityForResult , the application hangs with a blank screen and circular cursor. The file(s) are stored to app. What I have done: Before and after this issue I researched how to open files by use of Intents. I found a number of similar but different approaches and either used the literal example or a combination of various examples to see if I could find and resolve the issue (see some below). I'm not receiving any type of error message that

问题 I have problems trying to launch another activity from the TWA via the intent URI. "intent://#Intent;scheme=subscriptionschemetwa;package=com.package.www.twa;end" The package name is unique in reality, of course. I've played around with them, added host, action, extras etc. to URI, but nothing had an effect. As I'm new to native development, I'd appreciate some help. The app itself is not publicly available on Google Play yet (only internally), it's signed and packaged with Bubblewrap, and

To overcome that I found FLAG_ACTIVITY_REORDER_TO_FRONT (from here) and thought it could called only onresume but it didn't. 回答1: FLAG_ACTIVITY_REORDER_TO_FRONT does exactly what you think it should do. However, if you start ActivityA and then ActivityA starts
