问题 My Android app is showing an html5 e-book in a WebView. I have a zipped file containing an e-book with all its resources: text, images and audio (mp3 files). In order to unzip the book I use shouldInterceptRequest(), which intercepts the file:///... requests, and returns the data via a WebResourceResponse object. The code works fine for text and images. When I get to audio resources, I get runtime errors, and the audio file is not played. Note: I do see the unzipped file is returned with the

问题 How would I go about streaming audio from one device to another over the internet? I'm aware of sending basic data using Java sockets, but wondering how to: Start streaming midway through a file (say, during the middle of a song) What format is needed for the data being sent. MediaPlayer can take a url as a data source, so how should the audio be represented when being sent from the server side? Thanks 回答1: Having implemented a music streaming app, I can share a little with you. If you want

问题 I am using a VideoView in my app and when I set the background colour with either the layout properties, or in the code itself, the background colour is laid over the top of my video and I cannot see it. 回答1: VideoView extends SurfaceView , which relies on PorterDuff.Mode.CLEAR to cut a hole in the view hierarchy so that you can see a native rendering surface underneath. If you make it fill itself back in with a solid color, you will not be able to see the video. While the video is playing,

问题 My app is having issues with the MediaPlayer streaming, specifically on Nexus 5. I'm not sure if this is Nexus 5 or API level 19 causing the problem. Basically my MediaPlayer gets prepared and I call MediaPlayer.start() , but the MediaPlayer doesn't begin streaming. This happens at random and only on my Nexus 5 device. When this happens, if I try seeking the MediaPlayer it begins to play. Is anyone else experiencing this? UPDATE: I've filed a bug against Android: https://code.google.com/p

However seekTo does not start from the position I have captured but from the beginning.

问题 I am having a weird issue reading the length/duration of a video file recorded with a device's camera by using MediaRecorder. The file is recorded into the application's private storage directory, which is set like so: mMediaRecorder.setOutputFile(context.getFilesDir() + "/recordings/webcam.3gpp"); After recording is complete, I attempt to read the length of the video with these methods: Method 1: MediaMetadataRetriever mediaMetadataRetriever = new MediaMetadataRetriever();
