问题 I want to play videos on different fragments in viewpager. I use multiple mediaplayers and surfaceviews for each fragment. When I swipe left or right, I want to pause and start videos as well. Swipe to next video has no problem at all but when i swipe to previous video(that is already playing) surfaceviews overlap. Meanwhile, I can play and pause videos without problem. I tried almost all possible combinations of setZorderMedia and setZOrderonTop but I failed. In short, the problem is that

问题 I've been writing an mp3 player for quite some time, but for some reason this exception: W/MediaPlayer: Couldn't open /storage/emulated/0/Music/generic music file.mp3: java.io.FileNotFoundException: No content provider: /storage/emulated/0/Music/generic music file.mp3 keeps popping up every time I try to play any song.

Should MediaPlayer.start() also be a new thread?

问题 The tutorial here explains that a service actually uses the main thread. So it uses prepareAsync to avoid blocking UIS: http://developer.android.com/guide/topics/media/mediaplayer.html#asyncprepare I was wondering where the async callback onPrepared runs. In the example onPrepared calls start of MediaPlayer . Is start also a CPU-intensive method? If it runs in the same thread, it also blocks. 回答1: MediaPlayer.start() is not an intensive operation in the least. The MediaPlayer uses its own

Note: - my url is not for local storaged file!! its for server side file. E/NuCachedSource2: source returned error -1, 10 retries left E/NuCachedSource2: source

setNextMediaPlayer not working

由 你。 提交于 2019-12-06 22:26:43
I am trying to find out how to use the android's MediaPlayer method setNextMediaPlayer which should smoothly transition from one player (song) to another. But do not know how to use the method since there is a lack of documentation. This is what i do and it does not work: final MediaPlayer mp1 = new MediaPlayer(); final MediaPlayer mp2 = new MediaPlayer(); try { mp1.setDataSource("http://song1.MP3"); mp2.setDataSource("http://song2.mp3"); mp1.prepareAsync(); mp1.setOnPreparedListener(new OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { mp1.start(); } }); mp1
