How to open specific third party activity?

Ok I want to open a specific Activity from a app, not my app. Let's say that I want to open this package com.test.app and inside that package TestActivity. How can I do this?

I have tried like this:

Intent i = new Intent();
i.setClassName(pack, activity);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(i);

Intent i = new Intent(pack+activity);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(i);

Intent i = new Intent();
i.setClassName(pack, "."+activity);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(i);

Intent i = new Intent(pack+"."+activity);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(i);

With all of them I'm having this error:

Unable to find explicit activity class {PACKAGE/ACTIVITY}; have your declared this activity in your AndroidManifest.xml?

NOTE: I do have the app installed with package com.test.app and with an activity TestActivity. So how could this be done?

I think you might have not declared the new java class in manifest file. If not then open your manifest file, open ANdroidmanifest.xml and inside the tag below tag write this

First, you must make sure that the target activity is exported. It must be exported explicitly with android:export="true", or implicitly, with an intent-filter. You can't send an Intent to any random Activity of any app.
