Struct android_tools::bundletool::BuildApks

pub struct BuildApks { /* private fields */ }

Generate a set of APKs from your app bundle

When bundletool generates APKs from your app bundle,it includes them in a container called an APK set archive, which uses the .apks file extension. To generate an APK set for all device configurations your app supports from your app bundle, use the bundletool build-apks command, as shown below.

bundletool build-apks --bundle=/MyApp/my_app.aab --output=/MyApp/my_app.apks

If you want to deploy the APKs to a device, you need to also include your app’s signing information, as shown in the command below. If you do not specify signing information, bundletool attempts to sign your APKs with a debug key for you.

`bundletool build-apks --bundle=/MyApp/my_app.aab --output=/MyApp/my_app.apks`
`--ks=/MyApp/keystore.jks`
`--ks-pass=file:/MyApp/keystore.pwd`
`--ks-key-alias=MyKeyAlias`
`--key-pass=file:/MyApp/key.pwd`

The table below describes the various flags and options you can set when using the bundletool build-apks command in greater detail. Only --bundle and --output are required—all other flags are optional

Implementations

impl BuildApks

pub fn new(bundle: &Path, output: &Path) -> Self

(Required) Specifies the path to the app bundle you built using Android Studio. To learn more, read [Build your project].

(Required) Specifies the name of the output .apks file, which contains all the APK artifacts for your app. To test the artifacts in this file on a device, go to the section about how to deploy APKs to a connected device

pub fn overwrite(&mut self, overwrite: bool) -> &mut Self

Include this flag if you want to overwrite any existing output file with the same path you specify using the --output option. If you don’t include this flag and the output file already exists, you get a build error

pub fn aapt2(&mut self, aapt2: &Path) -> &mut Self

Specifies a custom path to AAPT2. By default, bundletool includes its own version of AAPT2

pub fn ks(&mut self, ks: &Path) -> &mut Self

Specifies the path to the deployment keystore used to sign the APKs. This flag is optional. If you don’t include it, bundletool attempts to sign your APKs with a debug signing key

pub fn ks_pass_pass(&mut self, ks_pass_pass: String) -> &mut Self

Specifies your keystore’s password. If you’re specifying a password in plain text, qualify it with pass:. If you’re passing the path to a file that contains the password, qualify it with file:. If you specify a keystore using the --ks flag without specifying --ks-pass, build_apks prompts you for a password from the command line

pub fn ks_pass_file(&mut self, ks_pass_file: &Path) -> &mut Self

Specifies your keystore’s password. If you’re specifying a password in plain text, qualify it with pass:. If you’re passing the path to a file that contains the password, qualify it with file:. If you specify a keystore using the --ks flag without specifying --ks-pass, build_apks prompts you for a password from the command line

pub fn ks_key_alias(&mut self, ks_key_alias: String) -> &mut Self

Specifies the alias of the signing key you want to use

pub fn key_pass_pass(&mut self, key_pass_pass: String) -> &mut Self

Specifies the password for the signing key. If you’re specifying a password in plain text, qualify it with pass:. If you’re passing the path to a file that contains the password, qualify it with file:.

If this password is identical to the one for the keystore itself, you can omit this flag

pub fn key_pass_file(&mut self, key_pass_file: &Path) -> &mut Self

Specifies the password for the signing key. If you’re specifying a password in plain text, qualify it with pass:. If you’re passing the path to a file that contains the password, qualify it with file:.

If this password is identical to the one for the keystore itself, you can omit this flag

pub fn connected_device(&mut self, connected_device: bool) -> &mut Self

Instructs build_apks to build APKs that target the configuration of a connected device. If you don’t include this flag, build_apks generates APKs for all device configurations your app supports

pub fn device_id(&mut self, device_id: String) -> &mut Self

If you have more than one connected device, use this flag to specify the serial ID of the device to which you want to deploy your app

pub fn device_spec(&mut self, device_spec: &Path) -> &mut Self

Use this flag to provide a path to a .json file that specifies the device configuration you want to target. To learn more, go to the section about how to Create and use device specification JSON files

pub fn mode_universal(&mut self, mode_universal: bool) -> &mut Self

Set the mode to universal if you want build_apks to build only a single APK that includes all of your app’s code and resources such that the APK is compatible with all device configurations your app supports.

Note

build_apks includes only feature modules that specify <dist:fusing dist:include="true"/> in their manifest in a universal APK. To learn more, read about the [feature module manifest].

Keep in mind, these APKs are larger than those optimized for a particular device configuration. However, they’re easier to share with internal testers who, for example, want to test your app on multiple device configurations.

pub fn local_testing(&mut self, local_testing: bool) -> &mut Self

Use this flag to enable your app bundle for local testing. Local testing allows for quick, iterative testing cycles without the need to upload to Google Play servers.

For an example of how to test module installation using the --local-testing flag, see Locally test module installs

pub fn run(&self) -> Result<PathBuf>

Runs build_apks commands to build apks

Trait Implementations
