The problem is in the DefaultAutocompleteHistoryManager the line 36:
File historyFile = new File(context.getCacheDir(), BASE_AUTOCOMPLETE_HISTORY_DIR + historyFileName);
It won't creat the actual file in the filesystem.
Missing code is:
if (!historyFile.exists()) {
historyFile.mkdirs();
try {
historyFile.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
