Answer 1

Try this:

AppA's AndroidManifest.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.joy.AppA">
    .
    .
    .
    <activity
            android:name="com.joy.AppA.views.activities.StartGameActivity"
            android:label="Start Game">

            <intent-filter>
                <action android:name="com.joy.AppA.views.activities.LAUNCH_IT" />
            <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>

            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".views.activities.DashboardActivity" />

        </activity>

Then to send data to app a activity from app b, do this:

Intent i = new Intent();
i.setAction("com.joy.AppA.views.activities.LAUNCH_IT");
i.putExtra("gameRecord", gameRecord_array);
startActivity(i);

Answer 2

Maybe it can be useful:

Content Provider and Content Resolver components.

Content Resolver makes request to Content Provider, and the provider respond. This is similar to a communication between two different applications.

For example a client (Resolver) and a content manager(Provider).

This is an example tutorial: https://www.tutorialspoint.com/android/android_content_providers.htm

Hope it helps!
