问题 How do i use intent in android widget to open images in browser. 回答1: If the image is on the internet it would be as simple as this: String url = "http://www.picturesnew.com/media/images/image-background.jpg"; Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(url)); startActivity(i); However if the image is inside of your assets you can't open it in the browser. That's because the browser accepts URI data that starts with http . Furthermore the browser is a separate app and one

问题 I am currently facing the problem of setting pending action for two different activities to notification. I have a ParentActivity and a ChildActivity. I want open ChildActivity on notification click if currently it is running or paused, otherwise start ParentActivity. I tried this : ......... Intent resultIntent = new Intent(this, ChildActivity.class); TaskStackBuilder stackBuilder = TaskStackBuilder.create(this); stackBuilder.addParentStack(ParentActivity.class); stackBuilder.addNextIntent

问题 Recently I noticed strange behaviour when i tried to schedule Activities to be run in the future using AlarmManager. Look at the code below, the first activity is started in 20 seconds, while the second activity is not started in 40 seconds instead it is started only after 60 seconds. Can anyone explain why the second intent doesn't schedule the second activity to be called instead the third intent does. Does this mean that i can have only one intent for an activity in the AlarmManager. /

问题 I am using FusedLocationProvider API to register some Geofences with PendingIntent, when my app gets started (app was manually killed to trigger this behavior) via Geofence event, I start a background service to do some work. In this Service I create a separate background thread to do some long running tasks and I acquire a wake-lock so that I am sure my tasks are completed. The Service keeps running for longer period of times (30 - 50 minutes) even though It shouldn't be. It shouldn't be

问题 I have been working with this problem for three days now and I've looked at every single question on here for an answer. I have a widget with a button on it and all I would like it to do is start a service everytime it is clicked. The problem is that the button stops working randomly. I can't recreate it at all and I have no idea what causes it. My service calls stopSelf(); but I have had this problem with a broadcast receiver also so I believe the problem to be in the widget and not in the

问题 I have been looking for an answer for this question for a long time and no one seemed to have an answer.
