How to add image next to the links What I need to do is, add a little image next to the link whenever link is visible in the TextView. To make links visible I use android:autoLink="web" and links are also clickable and that works fine, but I need to add a little image next to the link that also indicates a link can be clickable. Problem here is that I would need to substring links out of the String and somehow add the image next to it and put them back in the String. I hope there is a simpler way to do this, if not, help me...

Kotlin channel.receive() does not timeout when used in withTimeout() block I want channel.receive() to timeout to do some other stuff when the channel does not receive a message after a specific time.

What am i doing wrong?

Android Oreo / Pie FusedLocationProvider background limitations I plan to use the FusedLocationProvider with a PendingIntent to receive location updates while my app is in background. Android Oreo limits the app to receive updates only a few times an hour. However, I am not sure about the limitations of Android Pie and the App Standby Buckets: Can I process the location data in the onLocationResult method every time an location update comes in or will the App Standby Bucket limit this? If possible, how long can the processing take place in the background?
