由 戏子无情 提交于 2019-11-26 22:51:12
问题 I would like to know if it's possible to use Firebase jobdispatcher to schedule an url hit and get the response in order to update the db. I would like it to run once per day at night. Does anyone know if this is possible? I can't find any good example of doing this.

I need to use Firebase jobdispatcher because I'm targeting API 16. Thanks in advance.

问题 Anyone can explain me how keepRunning works in the config.xml for Android.

If anyone can find the source where we can see how does it work, that will be great Thanks.

由 岁酱吖の 提交于 2019-11-26 20:57:16
Android new version - "Lollipop" (API 21) brings quite a few changes with it, but it comes with some price if you wish to target your app to that API. When we started adapting our apps to the new API, one of the first problems we've encountered is the IllegalArgumentException: Service Intent must be explicit If you have encountered the problem, and you are actually intending to use your intent in explicit way (meaning that when starting the service you are expecting to hit exactly 1 service action), here's a quick fix for turning implicit --> explicit: public static Intent
