Yes, I've already read the article...
This is th code for the onPause and onResume methods.
public void onResume(){
super.onResume();
if(!mWakeLock.isHeld()){
pm =
(PowerManager)getSystemService(Context.POWER_SERVICE);
mWakeLock =
pm.newWakeLock(PowerManager.FULL_WAKE_LOCK,getClass().getName());
mWakeLock.acquire();
}
System.gc();
System.runFinalization();
System.gc();
if(Sound.soundEnabled){
mNowPlaying.start();
}
}
@Override
public void onPause(){
super.onPause();
System.gc();
System.runFinalization();
System.gc();
mWakeLock.release();
if(Sound.soundEnabled){
mNowPlaying=Sound.getNowPlaying();
Sound.stopSound(mNowPlaying);
}
if (Profile.getActiveProfileIndex() != -1) {
Profile.getActiveProfile().saveData();
}
}
public void saveData() {
// Log.d("", "saving data!");
save();
saveActiveFile();
}
private void save() {
FileOutputStream fos = null;
DataOutputStream dos = null;
File file = new File(Main.instance.getFilesDir() + "/" +
Main.instance.getString(R.string.T_APPNAME) + getActiveProfileIndex()
+1);
try {
if(!file.exists()){
file.createNewFile();
}
fos =
Main.instance.openFileOutput(Main.instance.getString(R.string.T_APPNAME)
+ this.mProfileId, Context.MODE_PRIVATE);
dos = new DataOutputStream(fos);
int score = 0;
int status = 0;
int tries = 0;
for (int i = 0; i < MAX_LEVEL_NUMBER; i++) {
dos.writeInt(mLevels[i].getStatus().ordinal());

Hope it helps!
