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>
