Android Resources Checker

What

This program will inspect the resources of your app and help you understand which ones are not being used and could potentially be removed.

Main features:

• Identify the unused resources in your android project.
• Identify the unused resources in your android library (when you have a multi-repo setup)
• Listing of the unused resources (name, type and size)
• Deletion of the unused resources

Installing

This program requires Python, supporting from 3.8.x and 3.9.x

In order to install run:

pip install -U android-resources-checker

Using

Inspecting your app resources.

Imagining your app in the project subject-app, you can trigger the resources inspection by running:

android-resources-checker --app /path/to/subject-app

Inspecting your library app resources.

In the case you have two projects in separate repos, where a client-app depends on a lib-app, you can check the unused resources of the library app by running:

android-resources-checker \
  --app /path/to/lib-app \
  --client /path/to/client-app-1 \
  --client /path/to/client-app-2

An example of a run could look like this:

Reports

The default behavior is to generate reports on both the stdout and CSV.

You can specify a single type of report using the --report=(CSV|STDOUT) option.

If using CSV reports, you can specify the directory where to write the reports in the form of CSV files. For that use the --reports-dir option.

For example:

android-resources-checker \
  --app /path/to/app \ 
  --reports-dir /path/to/reports

Validation

There is also the option to run this as a validation tool. In this case, it will fail with an error if any unused resources are found.

To specify the validation use the --check flag (the default behavior is to perform no validation).

Automatic Deletion

You can use this tool to also delete the unused resources by using the --delete option.
