How to properly take a screenshot, globally?

问题 Background Since Android API 21, it's possible for apps to take screenshots globally and record the screen. The problem I've made a sample code out of all I've found on the Internet, but it has a few issues: It's quite slow. Maybe it's possible to avoid it, at least for multiple screenshots, by avoiding the notification of it being removed till really not needed. It has black margins on left and right, meaning something might be wrong with the calculations : What I've tried MainActivity.java

问题 I want to build an app where I have to use MediaProjectionManager in a Service. But I can not solve it as 'startActivityForResult' can't use in Service class. 回答1: I really want to do this from a service, which is how I found this question. This is the closest I've came up, so just throwing this out there, till a better answer comes along. Here's a way to do it from an activity that's almost like doing it from a service: import static your.package.YourClass.mediaProjectionManager; public

问题 I'm trying to record the contents of the screen using mediarecorder and mediaprojection api. When I'm trying to change the video to HD on my device the recording fails but it works fine with 640 x 480 resolution. So my question is how could I get the supported video resolutions on a particular device? Cheers Jon 回答1: If your only interest is in API 21+, you can use the getVideoCapabilities() method. The CamcorderProfile class has been around since API 8, but isn't quite as useful. If all else

ScreenCapture via MediaProjection without user intervention in Kiosk apps - Android

由 爱⌒轻易说出口 提交于 2019-12-07 17:04:13
问题 I work for a digital signage company which has Android devices running in kiosk mode. Lately, we wanted to add screen capture for debugging. The easiest way to do that was to use getWindow().getDecorView().getRootView().getDrawingCache() to create bitmap and to send it over the network, but this will not capture videos as it's been rendered in surface view. MediaProjection's createVirtualDisplay seems promising, but the explicit permission needed to use this feature is not acceptable. Even
