Hello GoKu,

did you ensure, that the paht to the file is correct ?

public void setDataSource(String path)
- Sets the data source (file-path or URL) to use.
- Parameters: path The path of the file, or the URL of the stream you want to play.


As it should throw an exception on a bad path I assume your path is correct.

The second thing:
is the TextView t updated :?:

Tanks plusminus,

1) I'm ensure that path is correct. I copy the file in the emulator:

adb push "[nameFile]" sample.mp4

2) the command "mp.getDuration()" return a value != 1 and the TextView is updated;
