(#) Every Initializer needs to be accompanied by a corresponding entry in the AndroidManifest.xml file !!! ERROR: Every Initializer needs to be accompanied by a corresponding entry in the AndroidManifest.xml file This is an error, and is also enforced at build time when supported by the build system. For Android this means it will run during release builds. Id : `EnsureInitializerMetadata` Summary : Every Initializer needs to be accompanied by a corresponding entry in the AndroidManifest.xml file Severity : Fatal Category : Correctness Platform : Android Vendor : Android Open Source Project Identifier : androidx.startup Feedback : https://issuetracker.google.com/issues/new?component=823348 Min : Lint 8.0 and 8.1 Compiled : Lint 8.0 and 8.1 Artifact : [androidx.startup:startup-runtime](androidx_startup_startup-runtime.md.html) Since : 1.0.0 Affects : Kotlin and Java files and manifest files Editing : This check can *not* run live in the IDE editor Implementation : [Source Code](https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:/startup/startup-runtime-lint/src/main/java/androidx/startup/lint/EnsureInitializerMetadataDetector.kt) Tests : [Source Code](https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:/startup/startup-runtime-lint/src/test/java/androidx/startup/lint/EnsureInitializerMetadataTest.kt) Copyright Year : 2020 When a library defines a Initializer, it needs to be accompanied by a corresponding entry in the AndroidManifest.xml file. (##) Including !!! This is not a built-in check. To include it, add the below dependency to your project. ``` // build.gradle.kts implementation("androidx.startup:startup-runtime:1.2.0") // build.gradle implementation 'androidx.startup:startup-runtime:1.2.0' // build.gradle.kts with version catalogs: implementation(libs.startup.runtime) # libs.versions.toml [versions] startup-runtime = "1.2.0" [libraries] # For clarity and text wrapping purposes the following declaration is # shown split up across lines, but in TOML it needs to be on a single # line (see https://github.com/toml-lang/toml/issues/516) so adjust # when pasting into libs.versions.toml: startup-runtime = { module = "androidx.startup:startup-runtime", version.ref = "startup-runtime" } ``` 1.2.0 is the version this documentation was generated from; there may be newer versions available. [Additional details about androidx.startup:startup-runtime](androidx_startup_startup-runtime.md.html). (##) Suppressing You can suppress false positives using one of the following mechanisms: * Using a suppression annotation like this on the enclosing element: ```kt // Kotlin @Suppress("EnsureInitializerMetadata") fun method() { problematicStatement() } ``` or ```java // Java @SuppressWarnings("EnsureInitializerMetadata") void method() { problematicStatement(); } ``` * Using a suppression comment like this on the line above: ```kt //noinspection EnsureInitializerMetadata problematicStatement() ``` * Adding the suppression attribute `tools:ignore="EnsureInitializerMetadata"` on the problematic XML element (or one of its enclosing elements). You may also need to add the following namespace declaration on the root element in the XML file if it's not already there: `xmlns:tools="http://schemas.android.com/tools"`. ```xml <?xml version="1.0" encoding="UTF-8"?> <manifest xmlns:tools="http://schemas.android.com/tools"> ... <meta-data tools:ignore="EnsureInitializerMetadata" .../> ... </manifest> ``` * Using a special `lint.xml` file in the source tree which turns off the check in that folder and any sub folder. A simple file might look like this: ```xml <?xml version="1.0" encoding="UTF-8"?> <lint> <issue id="EnsureInitializerMetadata" severity="ignore" /> </lint> ``` Instead of `ignore` you can also change the severity here, for example from `error` to `warning`. You can find additional documentation on how to filter issues by path, regular expression and so on [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html). * In Gradle projects, using the DSL syntax to configure lint. For example, you can use something like ```gradle lintOptions { disable 'EnsureInitializerMetadata' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore EnsureInitializerMetadata ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
