I've coded up apps using VideoView and MediaPlayer and both had the same behavior. I'm currently using the code example here. The problem I'm having is that the video doesn't play back continuously. The slider in the MediaController is moving but the picture doesn't change. If I manually drag the slider the picture will change like it should.
I'm using an mp4 file loaded from the sdcard with a SDK 2.3.1 emulator device.
Any help is appreciated.
You usually cannot test video playback applications on the Android emulator, as it is too slow, except on very powerful host PCs. Please test video playback applications on an Android device.

Has anyone been able to successfully play a HD video using Android Things on a Raspberry Pi? If so was there anything special you had to do to get it to work? If not does any one know why it isn't working?
I made a simple video player that plays a local video from disk. The app runs fine on a phone but with android things maximum frames are getting dropped.
I am using ExoPlayer for the video playback and the same issue is observed when Media Player is used.Hardware acceleration is also enabled in the manifest file.
I am working with html5 video tag, i am using .m3u8 file for source. I can not able to seek video by using currentTime property in android 4+ whereas if i using .mp4 file i can able to seek.
In ipad its working properly but not working in android. Please guide me to rectify this issue.
Thanks,

HLS and Android are not the best of friends.
Some problems I know of are:
No adaptive bitrate switching: the first quality is picked, no switching will occur.
When pausing, the video restarts from the beginning (for example with VOD).
When going fullscreen, the video restarts from the beginning.
When offering a livestream with DVR, the stream starts at the beginning of the DVR instead of at the "live" moment.
You cannot seek. <-- this is the one for you
Aspect ratio's are not detected properly. (tho this should be fixed in 4.1)
On top of these problems, there is no support for HLS in pre 2.3 Android and in 3.0 it actually makes your tablet crash.
Basically: only use HLS on Android for live video without DVR and set the correct aspect ratio. Oh, and try to pick a "suitable" quality, cause it won't switch.
When i run my application on the tablet(android) and hit the pause button it pauses the screen of the video but the video will jump a head how ever many seconds the pause when i un-pause the video. So if i start the video and then click pause and walk away i can come back and un-pause the video and it well jump right to the end.
The code i am using is ns.togglePause(); This same code works on the desktop and works with .flv and .f4v but will not work when i am using a mp4 on the tablet.
Has anyone seen this before or know why it would do something like this?
i am using flashdevelop to debug the application.
I found out that my problem is caused by encoding. This helped me solve my problem.I found this on adobes forms.
Video encoding is very important.
For example, use baseline profile level 3.1 for H264 for mobile
(and not High profile level 4.1 recommended for desktop).
For more information, see the MAX session of Fabio Sonnati:
"Encoding for Performance on Multiple Devices"
And if you have an Android phone/tablet, there is my AIR application

(For info, i use a video player based on OSMF 1.6)

I got a problem when using videoView to play progressive streaming mp4 videos. Sometimes, when I scrub through the video, the view does not change accordingly and just hang there. It's strange because the time on the videoView is still running which mean the player is running.
I test this on an Android 2.2 device. Is this problem caused by videoView ?
Thank you.
Since android emulator plays .mp4 and .3gpp format videos and the android's video view is not that much good to play a video without pixcelet or hanging it. But if you try to run the same application on an android phone the video will play fine without picxeleting and without being hang. I too faced the same problem earlier with emulator but when I ran the code on android phone it worked great.
Guys
I am new to android and want to write a simple application that plays a video in android using video view. I have written the code it is working but the view is not clear. It is blurred. What should I do?? Please Help.
Is there any alternative to video view to achieve that...?? I want to play the recorded video from android phones
There are two possibilities. Either the quality of the video might be low or you would have tried it in a emulator. Sometimes it is possible for emulator to have some problems with playing video which I have personally faced. So you have to try it in a real device.
And regarding alternative for videoview, there is no such alternatives available I believe. But still videoview should be simple to play a video.
