问题 Recently i have ported a video decoder to android successfully. Also dumped the output on a surfaceview and checked the output using native API's. Now the next task is to implement play, pause, streaming etc. i.e. the other features of the media player. Doing this will be a rework as all these functionalities are already defined in the android multimedia framework. I heard that we can make our decoder as a plug-in and integrate it into Android's multimedia framework. Although i googled

Thanks 回答1: There are two ways that enforcing mode is set. On user builds, it will always be in enforcing. On eng or userdebug, you can control it. You can control it in the standard selinux way, by setting enforcing=1/0 on

问题 For my thesis, I'm modifying the android framework and building the source (4.1.1 Jelly Bean). I can do a full build, but because this is very time consuming (I'm developing on a ubuntu 12.04 64bit virtual machine) I'd like to build separate modules. For example: When doing changes to the location modules, it should be possible to just build the changed module, and make a new system image: mmm frameworks/base make snod But this doesn't work. Every time I try to boot, the new system image won

问题 I want to create Android application, which will record all audio from the device speakers. For example somebody is watching youtube video on the phone and he will be able to save sound from it, using my application. Is it possible without framework modification ? 回答1: There's the Visualizer class that let's you grab a low-quality version of the currently playing audio. It probably wouldn't be good enough for the use-case you describe though. Other than that there's no officially supported

问题 With android 4.4 I'm finding that some users are having the notificationListenerService I've implemented will just stop working. I've actually seen this myself too. I've never managed to capture any logcats around the time of it happening, but even going into the notification access section and switching off and back on the notification access doesn't help. Is there something that can cause this to happen. I'm not sure if my app is crashing and causing this, but even if so it seems the only

问题 I'm using the notification listener service in android 4.4 and I'm coming across an error that causes my app to stop getting notifications posted. It's fairly random, but when it happens I'm seeing: 12-31 01:40:44.080 21680-21680/?

问题 I have written a system server/service in android framework. As far as i know it has the system level permissions. But when i call this service using an app i get the permissions of application calling that service. Could anyone explain this behaviour? Also how could i resolve this? 回答1: When in your service you try to call method from other service, try to put the code of call into the following code block: long token = Binder.clearCallingIdentity(); //your call Binder.restoreCallingIdentity
