For the record, here is the code:
MediaPlayer player = new MediaPlayer();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
player.setDataSource(" http://mybigmp3.mp3 ");
} catch (IllegalArgumentException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IllegalStateException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
player.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
player.start();
And the logcat:

've never tried an MP3 that big - it's quite possible that it won't
work. I think the largest file we ever tested was a one hour MP3 mix
file. I think it was about 70 MB.

I don't understand why he writes in sdcard. Before he writes in tmp
dir.
I have try another prototype of createTempFile to specify a base
directory, but i have same problem
Do you have an idea?

2. SharedPreferences not stored betweed 2 emulator launch
Hi,
I have the following unexpected behaviour :
-> 1 start my application
-> I define a preference, thanks to the new mechanism (preferences
inflated from XML)
-> I stop my application
OPTION 1 :
-> I start my application for a second time, I check the preferences,
value is OK
OPTION 2 :
-> I close the emulator
-> I restart the emulator
-> I start my application, I check the preferences, value is NOT ok
(as not defined).
I was thinking the preferences are saved between two emulator
sessions.
Do I miss a point ?
Here is my preferences.xml file :
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="Filter algorithm">
<ListPreference
android:key="units.returned"
android:title="Displayed units"
android:summary="Number of unit to be displayed on the
map screen"
android:entries="@array/values_unit"
android:entryValues="@array/values_unit"
android:persistent="true"
android:dialogTitle="Set the displayed units number"/
</PreferenceScreen>
Thanks for your help.
