问题 I want to work on Adaptive playback the new feature in android 4.4. But I am confused how will I test the same. I will be using HTTPS links for video. Has anyone worked on it and can help how did they achieve it. Thanks in Advance. 回答1: CTS has adaptive playback as one of its tests: AdaptivePlaybackTest.java.

问题 Since I'm targeting my project to SDK 19 (KitKat), I randomly get this Message on a Nexus 7 (2013 | SDK 18): 11-07 17:54:27.502: E/bcc(2033): Invalid RS info file /data/data/<package>/cache/com.android.renderscript.cache/<script-name>.o.info!

问题 In my app I start an Intent to pick a video file like this Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.setType("video/*"); startActivityForResult(intent, kVideoPickerRequestCode); When it comes back i get the Uri like this: if(resultCode == RESULT_OK) { if (requestCode == kVideoPickerRequestCode) { Uri selectedVideoURI = data.getData(); } } This Uri seems to be fine for my VideoView.

问题 I tried to search if there are any suggestions but couldn't find enough hence this question to help me out.

问题 Android 4.4 Kit Kat introduced the ImageReader class for accessing the image in the Surface, useful for real-time processing of a camera preview. However, I can't figure out how to link it to the Surface or use it. Anybody have any insights or short example code? 回答1: You can find an example in the camera CTS tests. As noted in the comments, ImageReader isn't actually usable until 5.0 ("Lollipop"). 来源： https://stackoverflow.com/questions/21147519/how-to-use-the-imagereader-that-appeared-in

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
