Make App Portrait Only Android
As an Android developer, you might come across scenarios where you want your app to be displayed only in portrait mode. Whether it’s to enhance the user experience or maintain consistency with the design, making your app portrait only can be achieved through a few simple steps.
Key Takeaways:
- Making your app portrait only on Android can enhance user experience and maintain design consistency.
- By adjusting the manifest file and handling screen orientation programmatically, you can ensure your app stays in portrait mode.
- Enabling portrait-only mode can prevent UI layout issues and improve app performance on different screen resolutions.
To make your Android app display in portrait mode only, you need to modify the AndroidManifest.xml file of your project. By adding a specific attribute to the activity, you can enforce portrait orientation for that particular screen. Here’s an example:
<activity
android:name=".MainActivity"
android:screenOrientation="portrait">
// Your activity code here
</activity>
Handling screen orientation programmatically can sometimes introduce challenges, especially when dealing with complex layouts or dynamic content. Fortunately, the Android framework provides a way to lock the screen orientation explicitly, preventing any unwanted changes. You can achieve this by calling the setRequestedOrientation method within your activity’s code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
// Rest of your code
}
It’s important to note that locking the screen orientation should be used judiciously to ensure optimal user experience. Some situations may require the app to adjust to different screen orientations, such as landscape mode for media playback or certain games.

Frequently Asked Questions
How can I make my Android app portrait-only?
Answer: To make your Android app portrait-only, you can set the screen orientation of your activities in the AndroidManifest.xml file using the android:screenOrientation attribute. By setting it to “portrait”, the app will only be displayed in portrait mode, regardless of device orientation. Add the following code to your activity declaration:
<activity android:name=".MainActivity" android:screenOrientation="portrait">
Will setting my app to portrait-only affect tablet devices?
Answer: Yes, setting your app to portrait-only will affect tablet devices as well. Tablet devices usually have larger screens, and by default, they may allow both portrait and landscape orientations. However, when your app has a portrait-only setting, it will override the system’s default behavior and enforce the app to be displayed in portrait mode only, even on tablets.
Does making my app portrait-only guarantee compatibility with all Android versions?
Answer: Making your app portrait-only does not guarantee compatibility with all Android versions. While the android:screenOrientation attribute is supported from Android version 1.0 onwards, the specific behavior may vary across different devices and Android versions. It is recommended to thoroughly test your app on various devices and Android versions to ensure proper functioning.
Can users still rotate their device to landscape mode while using my portrait-only app?
Answer: When you make your app portrait-only, users will not be able to rotate their device to landscape mode just for your app. The system will lock the screen orientation to portrait, overriding any attempts to rotate the device to landscape while your app is active.
What if my app requires landscape orientation for certain activities or views?
Answer: If your app requires landscape orientation for certain activities or views, you can override the portrait-only setting for those specific components. In the AndroidManifest.xml file, set the android:screenOrientation attribute to “landscape” for the activities or views that need landscape orientation, while keeping the rest of the app portrait-only.
How can I handle orientation changes in my portrait-only app?
Answer: In a portrait-only app, orientation changes are not expected. However, if you need to handle orientation changes for a specific purpose (e.g., displaying different layouts or handling device rotation during a specific task), you can override the onConfigurationChanged() method in your activity. This allows you to manually handle the changes and prevent any unwanted behavior.
Can I force my app to stay in portrait mode by disabling the auto-rotate feature on the device?
Answer: No, you cannot force your app to stay in portrait mode by disabling the auto-rotate feature on the device. The auto-rotate feature is controlled by the system and affects all apps on the device. Even if the user disables auto-rotate, your app will still adhere to the screen orientation specified in the AndroidManifest.xml and will remain portrait-only when active.
Is it possible to make my app portrait-only programmatically at runtime?
Answer: Yes, it is possible to make your app portrait-only programmatically at runtime. You can use the setRequestedOrientation() method in your activity to set the desired screen orientation dynamically based on certain conditions or user interactions. For example, if you want to switch to portrait mode when a specific event occurs, you can call setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT).
Are there any UI guidelines or best practices for designing portrait-only apps?
Answer: While there are no specific UI guidelines or best practices solely for portrait-only apps, it is generally recommended to design your app’s UI to be flexible and adaptable to different screen sizes and orientations. Consider utilizing responsive layouts, using appropriate padding and margins, and ensuring proper text and image scaling to provide a seamless user experience in any orientation. Test your app on different devices to verify that it looks and functions well in portrait mode.
