Modifying the displayed title of an application on the Android operating system involves altering the value associated with the `android:label` attribute within the application’s manifest file. This attribute dictates the text that appears beneath the application’s icon on the device’s home screen and within the application launcher. For example, if the application is initially named “My App,” changing the `android:label` to “New App Name” will result in the latter being displayed to the user.
The ability to rename an application is crucial for branding, marketing, and overall user experience. It enables developers to refine the application’s identity, reflect updated features, or correct initial naming errors. Historically, this process has remained consistent across different versions of the Android SDK, offering a reliable method for application customization.
The following sections will detail the specific steps and considerations required to successfully implement changes to the application’s displayed title, encompassing adjustments within the `AndroidManifest.xml` file, string resource management, and potential build variations.
1. AndroidManifest.xml modification
The `AndroidManifest.xml` file serves as the control center for every Android application, providing the system with essential information about the application’s components, permissions, and metadata. Modification of this file is a crucial step in the process of altering an application’s displayed name. Specifically, the `android:label` attribute within the “ tag or individual “ tags dictates the name that is displayed to the user. Changing the value assigned to this attribute directly affects the application’s visual identity on the device.
Without modification of the `AndroidManifest.xml`, the application would retain its original name, regardless of any other changes implemented within the application’s code. For example, if an application is initially built and deployed with the name “Example App” defined in the `AndroidManifest.xml`, users will consistently see this name on their home screens and in the application list. To change the name to, say, “New Example,” the `android:label` attribute in the `AndroidManifest.xml` must be updated accordingly. Failing to do so would result in a discrepancy between the desired name and the actual displayed name.
In summary, modification of the `AndroidManifest.xml` file, particularly adjusting the `android:label` attribute, is an indispensable component of modifying an Android application’s displayed name. This understanding ensures developers can effectively manage the visual identity of their applications and deliver a consistent user experience. Incorrect or absent modifications will result in the application retaining its original name, negating any intended changes.
2. `android
The `android:label` attribute within the `AndroidManifest.xml` file is the definitive declaration of an application’s name as presented to the user. Therefore, understanding its function is paramount to any strategy addressing “how to change the app name in android.” It acts as a single source of truth for the displayed application identity.
-
Direct Display Control
The `android:label` attribute directly dictates the text displayed beneath the application’s icon on the home screen and in the application launcher. Without proper configuration of this attribute, any attempts to modify the application’s name will be ineffective. For example, if the attribute is set to “My Application,” that text will invariably be shown to the user, irrespective of other internal naming conventions or resource modifications.
-
String Resource Referencing
The `android:label` attribute accepts either a hardcoded string value or, preferably, a reference to a string resource defined in the `strings.xml` file. Using a string resource, represented as `@string/app_name`, promotes localization by allowing different translations of the application name for various locales. This is crucial for applications targeting a global audience, as failing to localize the application name can hinder user adoption and satisfaction.
-
Activity-Specific Overrides
While typically defined at the “ level in the `AndroidManifest.xml` file, the `android:label` attribute can also be specified within individual “ declarations. This enables developers to provide specific titles for individual activities within the application. For instance, a settings activity might have a label of “Settings” while the main activity has a label reflecting the overall application name. In situations needing distinct labels for activities within an app, the activity-level setting takes precedence over the application-level one.
-
Implications for Updates
Changing the `android:label` attribute is a critical consideration during application updates. Users expect to see consistent naming, and sudden or unexplained changes to the application name can lead to confusion or distrust. Thorough testing and clear communication with users regarding name changes are essential to maintain a positive user experience.

The string resource file, typically named `strings.xml` and located within the `res/values` directory of an Android project, is integral to managing text-based elements within an application, including the displayed application name. Employing this file offers significant advantages when modifying an application’s name, supporting localization and simplifying future adjustments.
-
Localization Support
Using a string resource allows for straightforward localization of the application name. Different `strings.xml` files can be created for various locales, enabling the display of the application name in the user’s preferred language. For instance, the default `strings.xml` might contain `My App`, while a Spanish version could contain `Mi Aplicacin`. This ensures a culturally appropriate experience for users in diverse regions. The alternativehardcoding the namecomplicates and inflates the application size due to the need to account for each language.
-
Simplified Modification
When the application name is defined within the `strings.xml` file, changing it only requires modifying the value associated with the string resource. If the application’s `android:label` attribute in the `AndroidManifest.xml` refers to this string resource (e.g., `android:label=”@string/app_name”`), updating the `strings.xml` automatically updates the displayed name. This centralized approach avoids the need to search and replace the name throughout the codebase and XML files. For instance, to rename an app from “Project Alpha” to “Project Beta”, editing only the `strings.xml` file, not touching `AndroidManifest.xml`, is sufficient.
-
Maintainability and Consistency
By centralizing the application name in a string resource, developers ensure consistency across the application’s user interface. This single source of truth reduces the risk of typographical errors and inconsistencies that can arise when the name is duplicated across multiple files. Further, maintainability improves over time. Imagine a scenario with multiple activities each displaying the app name. Without a unified string resource, each location requires individual updates, a tedious process prone to errors.
-
Runtime Flexibility
Although less common for application names, using string resources allows for potential runtime modification of the displayed name based on specific application conditions. For example, the displayed name could be dynamically altered to reflect a user’s subscription level or a temporary promotional campaign. While not the primary function, the string resource approach provides this level of flexibility that is otherwise unattainable with hardcoded string literals in the manifest file.
In conclusion, string resource files offer significant advantages when addressing “how to change the app name in android”, encompassing localization, simplified modification, maintainability, consistency, and a degree of runtime flexibility. The `android:label` attribute in the `AndroidManifest.xml` should always reference a string resource to facilitate efficient and effective application name management.
