I really don't know what method to use! all right, i have this: copyfile(context,"data/data/ carburant.android.com/files/alaa.peugeot.settings.dat",sdCard.getAbsolutePath() + "/Carburant/storeddata.dat");
I have to replace "data/data/ carburant.android.com/files/alaa.peugeot.settings.dat" by a method. Have i to use this? getFileStreamPath<http://developer.android.com/reference/android/content/Context.html#getFileStreamPath(java.lang.String)> (String <http://developer.android.com/reference/java/lang/String.html> name) Returns the absolute path on the filesystem where a file created with openFileOutput(String, int)<http://developer.android.com/reference/android/content/Context.html#openFileOutput(java.lang.String, int)> is stored. But the file created in the /data/data...... is not created with openFileOutput(String, int)<http://developer.android.com/reference/android/content/Context.html#openFileOutput(java.lang.String, int)> 2011/4/4 Kostya Vasilyev <kmans...@gmail.com> > A few things. > > 1 - For the target file, don't use "SDCARD" in your paths. > Environment.getExternalStorageDirectory already gives you the path to the > top-level directory ("root") of the memory card. > > Android 2.2 uses a path that's different from earlier versions, and you can > rely on this function to do right thing. > > 2 - For the source file, use this: > > > http://developer.android.com/reference/android/content/Context.html#openFileInput(java.lang.String > ) > > or > > > http://developer.android.com/reference/android/content/Context.html#openFileOutput(java.lang.String, > int) > > Do not try to build the full path yourself (as in, > "/data/data/<package_name>/files") - the path can be different depending on > the device and its Android version.
