my app AndroidManifest.xml 

```
 <activity
    android:name="com.test.orc.IdentifyIdcards"
    android:screenOrientation="landscape" >
      <intent-filter>
                    <action android:name="com_test_orc_IdentifyIdcards" />

                    <category android:name="android.intent.category.DEFAULT" />
                </intent-filter>
            </activity>

```

so any app can call my app by 

```
Intent intent = new Intent();
intent.setAction("start_photo_identify_picture_activity");
startActivity(intent); 

```

but I limit only the package name is `com.test.idcard` can call my app, how to do it?
