Hi everyone,
I have a machine running Android 14. I've successfully downloaded the BOINC app via apk from official website.
How do I exit "BOINC manager" but continue running tasks? (If there is a way)
Hope I've made myself clear. Thanks.

You may need to enable Wake Lock or disable battery optimization to prevent BOINC from being suspended while running in the background. Some phones use aggressive battery-saving features, and their behavior varies by manufacturer.

You can easily check whether the CPU is being utilized by the device's temperature or using tools such as CPU-Z.
Keep in mind that, by default, BOINC on Android only runs tasks while the device is on a charger and the battery level is above XX%. These settings can be adjusted in BOINC's preferences.
