parse_application_id ) // inside of another class (requires a context object to exist) String secretValue = context. You can access the secret values in your Java code with: // inside of an Activity, `getString` is called directly String secretValue = getString ( R. Once these keys are in the file, Android will automatically merge it into your resources, where you can access them exactly as you would your normal strings. Start by creating a resource file for your secrets called res/values/secrets.xml with a string pair per secret value: xxxxxx zzzzzz To read more about this approach, check out this article or this other article. Now you have access to as many secret values as you need within your app, but will avoid checking in the actual values into your git repository. CONSUMER_KEY String consumerSecret = BuildConfig. You can now access these two fields anywhere within your source code with the BuildConfig object provided by Gradle: // inside of any of your application's code String consumerKey = BuildConfig. load ( new FileInputStream ( apikeyPropertiesFile )) android file ( "apikey.properties" ) def apikeyProperties = new Properties () apikeyProperties. You'll also create compile-time options that will be generated from this file by using the buildConfigField definition: def apikeyPropertiesFile = rootProject. Next, add this section to read from this file in your app/adle file. To avoid these keys showing up in your repository, make sure to exclude the file from being checked in by adding to your. Hidden in BuildConfigsįirst, create a file apikey.properties in your root directory with the values for different secret keys: CONSUMER_KEY="XXXXXXXXXXX" The approaches below two ways of accomplishing the same goal. The simplest approach for storing secrets in to keep them as resource files that are simply not checked into source control. Storing Fixed Keysįor storing fixed API keys, the following common strategies exist for storing secrets in your source code: You can also specify which files to avoid backups too by reviewing this doc. The alternative is to disable backups by setting android:allowBackup in your AndroidManifest.xml file: You should not store them in shared preferences without encrypting this data first because they can be extracted when performing a backup of your data. If you are using dynamically generated secrets, the most effective way to store this information is to use the Android Keystore API. Often your app will have secret credentials or API keys that you need to have in your app to function but you'd rather not have easily extracted from your app.
