The answer depends on what you intend to do with the projects.

If you wish to merge the project into a single app , at least one of them should be set as an android library , and another project should use it . This way , the merged projects would be able to recognize each other .

If you wish to have 2 apps and not a single app , each activity that you wish to access from another activity should have a special definition in the manifest (using intent filter) of how to open it , as it's not the default behavior .

If all you need is to show a new MainActivity instance you need to declare an intent-filter in your "2nd project" manifest:

 <activity android:name=".MainActivity">
   <intent-filter>
     <action android:name="your.package.here.MainActivity" />
     <category android:name="android.intent.category.DEFAULT" />
   </intent-filter>
 </activity>

Then create an intent with the same action string in your first project:

Intent intent = new Intent("your.package.here.MainActivity");
startActivity(intent);
