How to cause activity in another project?

Hi, I am new to android and I created 2 projects.

Now I want to call an action in the second project from the first project when I click the button.

The first project only processes the login screen, and when I click on the login button, I need to invoke an action that is present in the second project.

I searched the net but did not find the tutorials that I understood correctly.

Hi, I found the following error.

I declared a manifest like this.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.fluturasymphony.recommendation"
    android:versionCode="1"

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

        </activity>

        </activity>
                <uses-library android:name="com.google.android.maps" />


    </application>



</manifest>

And I call activity in the second grade as follows.

Intent loginintent = new Intent("com.androidhive.googleplacesandmaps.MainActivity");
                        startActivity(loginintent);

Is it correct?

You must use one project for each application. If you want to separate your login from the rest of your application, you can use different packages. If I do not understand, what do you mean by "project"?
