Struct android_manifest::UsesNativeLibrary

pub struct UsesNativeLibrary {
    pub name: String,
    pub required: Option<bool>,
}

Specifies a vendor-provided shared native library that the application must be linked against.

This element tells the system to make the native library accessible for the package.

NDK libraries are by default accessible and therefore don’t require the <uses-native-library> tag.

Non-NDK native shared libraries that are provided by silicon vendors or device manufacturers are not accessible by default if the app is targeting Android 12 or higher. The libraries are accessible only when they are explicitly requested using the <uses-native-library> tag.

If the app is targeting Android 11 or lower, the <uses-native-library> tag is not required. n that case, any native shared library is accessible regardless of whether it is an NDK library.

This element also affects the installation of the application on a particular device:

Installation

If this element is present and its android:required attribute is set to true, the PackageManager framework won’t let the user install the application unless the library is present on the user’s device.

The android:required attribute is described in detail in the following section.

Fields

name: String

The name of the library file.

required: Option<bool>

Boolean value that indicates whether the application requires the library specified by android:name:

• "true": The application does not function without this library. The system will not allow the application on a device that does not have the library.

• "false": The application can use the library if present, but is designed to function without it if necessary. The system will allow the application to be installed, even if the library is not present. If you use "false", you are responsible for gracefully handling the absence of the library.

The default is "true".
