回答1:

Refer these two links from stackoverflow. It will help you

1. How to call activity of one project from activity of another project in android?Also vice versa?

2. How to call an activity in another project?

回答2:

change

   intent = new Intent("com.example.projectb.reading");
    startActivity(intent);

into

    intent = new Intent("com.xample.projecta.cls_show");
    startActivity(intent);

回答3:

you are using wrong Constructor

intent = new Intent(this, "com.example.projectb.reading");
        startActivity(intent);

read intent for more information.

回答4:

You can achieve that by Intent-filter.

FirstActivity

Intent intent = new Intent("com.example.secondapp.SecondActivity");
startActivity(intent);    

SecondActivity - AndroidManifest.xml

    <activity
        android:name="com.example.secondapp.SecondActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.example.secondapp.SecondActivity" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
