Public Activity - Creating activities based on certain attribute changes

will help you ActiveModel::Dirty handles tracking changes to attributes in your model. There are a number of ways to tell whether or not a specific attribute did change:
changed_attributes returns a Hash of model changes before save (meaning it is {} after a save because you have a clear, unchanged state for the current object). That won't work in your controller. previous_changes returns a Hash of attributes that were changed by a save. This is what you want for your controller.
code :
def update
  @post = Post.find(params[:id])

  if @post.previous_changes.key?('time_zone')
    @post.create_activity(:update, owner: current_user)

        Button b = (Button) findViewById(R.id.button1);

    public void onClick(View v) {

        final Intent mainIntent = new Intent(Intent.ACTION_PICK_ACTIVITY, null);
        final List pkgAppsList = this.getPackageManager()
                .queryIntentActivities(mainIntent, 0);
        Log.e("App", pkgAppsList.toString());
        startActivityForResult(mainIntent, RESULT_OK);

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Toast.makeText(this, "Hello", Toast.LENGTH_LONG);

will help you activity.trackable will give the model that is being tracked. it is a polymorphic association.
Lets say the user has created a new post and discussion is set to true. In that case activity.trackable will give you the Post model object and all its methods will work as normal, so you activity.trackable.discussion will give you true/false, based on the example i said, it will return true

will be helpful for those in need This seems to be a bug in the latest (as of Mar 13, 2014) ADT bundle release. An update through Eclipse's Install New Software window should fix it. To do this, you can try the following:
In Eclipse, go to Help -> Install new software; Pick main update site having the URL http://dl-ssl.google.com/android/eclipse; In the bottom section disable "Contact all update sites during install to find required software"; this causes issues when updating; Check Developer Tools; Perform the rest of the update;
