Force new parse installation

as I previously asked in this question: Clear parse installation cache on Android

I would like to delete/clear the parse installation on my android phone when a user logs out of the app. I can delete the parse installation via a script from the web, then I have to clear it from the ram/disk on the phone.

My question is, how can I force the parse library to trigger creating a new parse installation after I do that?

I've been able to successfully delete the 'local' ParseInstallation cache using the android parse sdk 1.13.1

ParseInstallation installation = ParseInstallation.getCurrentInstallation();
Class clazz = installation.getClass();
Method[] methods = clazz.getDeclaredMethods();
Method method1 = clazz.getDeclaredMethod("getCurrentInstallationController");
method1.setAccessible(true);
Object result = method1.invoke(installation);

Method method2 = result.getClass().getDeclaredMethod("clearFromDisk");
method2.setAccessible(true);
String result2=(String) method2.invoke(result);

Method method3 = result.getClass().getDeclaredMethod("clearFromMemory");
method3.setAccessible(true);
String result3=(String) method3.invoke(result);

Everytime my app starts I check if the installation can be saved, if it can't I just recreate another installation.

This way, it's safe to delete the installation from parse-server depending on your use case, My ParseInstallation only holds a reference to my User object so I can query and send Push notifications.

final ParseInstallation installation = ParseInstallation.getCurrentInstallation();
        installation.put("user", ParseUser.getCurrentUser());
        installation.saveInBackground()
                .continueWithTask(new Continuation<Void, Task<Void>>() {
                    @Override
                    public Task<Void> then(Task<Void> task) throws Exception {
                        if (task.isFaulted()) {
                            try {
                                ParseInstallation installation = ParseInstallation.getCurrentInstallation();
                                Class clazz = installation.getClass();
                                Method[] methods = clazz.getDeclaredMethods();
                                Method method1 = clazz.getDeclaredMethod("getCurrentInstallationController");
                                method1.setAccessible(true);
                                Object result = method1.invoke(installation);

                                Method method2 = result.getClass().getDeclaredMethod("clearFromDisk");
                                method2.setAccessible(true);
                                String result2=(String) method2.invoke(result);

                                Method method3 = result.getClass().getDeclaredMethod("clearFromMemory");
                                method3.setAccessible(true);
                                String result3=(String) method3.invoke(result);

                            } catch (Exception ex) {
                                ex.printStackTrace();
                            }
                        }
                        return null;
                    }
                })

Hope this makes a little sense...
