I am playing audios in a gridview.I am having issue that once the audio starts it not pausing or stopping.On clicking on pause button I see the pause image changing to play but still the audio keeps playing.If i click on another item's play button then multiple audio plays.I failed to understand why mp.pause() not working?
You are creating a MediaPlayer for each item of your GridView. If you scroll, it will mess up the references to your view and you won't be able to handle your MediaPlayer. You should use only one MediaPlayer, like the one you already have declared mMediaPlayer. Try using it instead of creating one for each item.
In my application I am displaying around 30 animal images using viewpager. each page has full screen image and play sound button. Clicking on button will play displayed animals sound. So there are 30 different sound files in raw folder. how to play audio effectively when user press button? What to use mediaplayer or soundpool? and how to use it effectively? Please give me solution.
Keep the song files in the raw folder and then on the button's onClick method execute the songs play.
You can use a switch case for different id's of button.
My application has several pages of book. In some of page I am playing video using video view. I am checking if I have any video for that page. If yes, than I am making videoview visible and passing Uri. If not, I am making it gone.
Now the problem is, once i reached to that screen and then if I swipe left/right it's creating black window in every subsequent screen. Why?
I found solution. When you want to show video make videoView.setZOrderOnTop(false); and when you want to hide video view jusr make videoView.setZOrderOnTop(true);
I'm trying to make a video player with VideoView that supports subtitles using a TextView on top of it.
I've already parsed the subtitles but now i need an event that runs every time a frame changes or so to update the subtitles with the current playing position.
I tried making a thread but I am not able to change my TextView in that separate thread. Is there an event on VideoView/MediaPlayer that runs every frame change that I can override to call my updateSubtitle method?
Starting with Android 4.4 , you can put subtitles from within the VideoView itself:

Coming to your first question, there is no event that happens each video frame. Having said that there are ways of getting current time and synchronize subtitles to the current time. Below links might be of help
