I am developing media player and my application download mp3 file from server .
So i want to prevent it from another media player to play it.
Case
User get file from server (music file1.mp3) in android phone ! User play it in our player but can't share it or download it in computer or play in another media player.
I try Below
I can encrypt a file and decrypt it again in my app (will take long time, it's a mobile cpu!), but then my application needs to have the decryption key inside. Basically anyone can read this key from my app so its not the good solution.
So please suggest me what i have to do ?
Thanks..

Write some other app.
What you are describing is DRM. There is no known DRM system that is unbreakable. There are DRM systems that have been broken, and there are DRM systems that nobody has bothered trying to break yet.

I am creating a music application.
I have used Exoplayer V2.8.0, So far I have achieved to play, pause next, prev, shuffle, repeat all songs using controls in-app and also with notification.
But all of this works only in online mode.
Now I want to add offline support to this app and allow a user to download the song offline and play while they are offline.
Audio files we are getting are *.m3u8 files.
But my problem is user should not access those downloaded files outside of my app. I have tried using one approach but it gives the mp3 files downloaded and combined from the different segments of the m3u8 file.
Can anyone guide me or give me sample or tutorial on how can I download the segments only and at the time of playing I can use that segment and play audio offline?
There is one suggestion for you,
If you want to create an offline player with .m3u8 or any other file then after download saves your file into your package folder with some of the different formats. Then while using that convert that specific formatted to mp3 or other which will help out for offline music play.
You can use a local http proxy server (NanoHttpd). Start the server and point your ExoPlayer to 127.0.0.1 so you can monitor the requests. Cache the m3u8 playlist plus the downloaded files for the first time you see a request. Next time when your proxy detects the same request, just play the files from cache.
I am developing a video player where downloaded video tutorials have to be played offline.
I want to secure these video files. What is the best and economical way to encrypt these files per user
once user get video, they can share it with others. I want to restrict that.
Please suggest me some ideas of how I can protect these videos from piracy.
Please help
You could create a key per user and encrypt the file with that before downloading it into the user device. Using the same key you could decrypt the file while playing in you app
Ok, I have a video encrypted through AES, stored in the internal memory of an Android powered device. What i want is that the video should only be played through an android app.
It would be appreciated if that application would decrypt the video part by part, store it in a virtual memory, and then stream it.
My question:
Is it possible to decrypt it part by part and stream?
If Yes, what would be the basic process?
If No, (nothing is impossible to code)
To make it happen, do i need to design my own video player android app, or can i use some existing app to work inside my app?
This subject is already treated in many questions.
For instance, look at How to play an encrypted video file in Android
everyone!
Me and my team are developing some audio books that we will sell through our android application and our users will also listen them using the in-app mp3 player. We want to find a method (paid or free) to be able to protect our mp3's so the user cannot copy them and play with their own player.
I am aware that someone that is determined can crack anything, but our user targets are not computer geeks, but regular people that want a product that works and occasionally might try to cheat the system
Do you know any system that is easy to implement and can meet our objectives ?
Thank you in advance.

Stream the files from your server (e.g., using RTSP), or store them in internal storage on the device. Those will stop "regular people that want a product that works and occasionally might try to cheat the system" from being able to access MP3 files, which you can then play back using MediaPlayer within your own app ("in-app mp3 player").
I've been following this blog to help me make a simple music player function with an Android app (http://simonmacdonald.blogspot.com/2011/05/using-media-class-in-phonegap.html).
All works well - but I would like some way to extract a list of all music media stored on the phone so the user can click a file and play it. Does anyone know if this is possible via phone gap? I'd need to access track name/artist etc and a link to the track.
Cheers

Prognosis is not good.... PhoneGap does not have an API for accessing the media library. So, you would have to fall back to the File API to locate music files, and then... you would have to read the binary data in the actual files to extract out the track/artist metadata. Ouch. Seems pretty impractical.
[EDIT]
By the way, PhoneGap is not the only game in town. Appcelerator seems to solve the same problem, and apparently has a richer API, which includes
access to media metadata
