I have three activity and three Intent Filters for them in the Android Manifest.
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".firstActivity"
android:theme="@style/AppTheme"
android:label="@string/first">
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
</activity>
<activity
android:name=".secondActivity"
android:theme="@style/AppTheme"
android:label="@string/second">
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
</activity>
<activity
android:name=".thirdActivity"
android:theme="@style/AppTheme"
android:label="@string/third">
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
</activity ></application>
How can I disable the intent filters programmatically depending on some options? Or how can I create new intent filters in code?
Thanks.

An intent filter is an expression in an app's manifest file that specifies the type of intents that the component would like to receive. For instance, by declaring an intent filter for an activity, you make it possible for other apps to directly start your activity with a certain kind of intent.
Intent Filter Code Inside Android Manifest: The code of Intent Filter is used inside AndroidManifest.xml file for an activity. You can see it: open manifests folder >> open AndroidManifest.xml file. Table Of Contents. 1 Syntax of Intent Filters: 2 Attributes of Intent Filter: 3 Elements In Intent Filter:
If multiple intent filters are compatible, the system displays a dialog so the user can pick which app to use. An intent filter is an expression in an app's manifest file that specifies the type of intents that the component would like to receive.
To advertise which implicit intents your app can receive, declare one or more intent filters for each of your app components with an <intent-filter>element in your manifest file. Each intent filter specifies the type of intents it accepts based on the intent's action, data, and category.
You can neither enable, disable, or create <intent-filter>s programmatically.
However, in your case, you only have one <intent-filter> per component. In that case, you can enable and disable the component programmatically, via PackageManager and setComponentEnabledSetting(). In your case, enabling or disabling the activity would have the same basic effect as enabling or disabling its <intent-filter>.
