(#) RepeatOnLifecycle should be used with viewLifecycleOwner in Fragments. !!! ERROR: RepeatOnLifecycle should be used with viewLifecycleOwner in Fragments. This is an error. Id : `UnsafeRepeatOnLifecycleDetector` Summary : RepeatOnLifecycle should be used with viewLifecycleOwner in Fragments. Severity : Error Category : Correctness Platform : Android Vendor : Android Open Source Project Identifier : androidx.fragment Feedback : https://issuetracker.google.com/issues/new?component=460964 Min : Lint 7.0 Compiled : Lint 8.0 and 8.1 Artifact : [androidx.fragment:fragment](androidx_fragment_fragment.md.html) Affects : Kotlin and Java files Editing : This check runs on the fly in the IDE editor Implementation : [Source Code](https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:/fragment/fragment-lint/src/main/java/androidx/fragment/lint/UnsafeRepeatOnLifecycleDetector.kt) Tests : [Source Code](https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:/fragment/fragment-lint/src/test/java/androidx/fragment/lint/UnsafeRepeatOnLifecycleDetectorTest.kt) Copyright Year : 2021 The repeatOnLifecycle APIs should be used with the viewLifecycleOwner in Fragments as opposed to lifecycleOwner. (##) Including !!! This is not a built-in check. To include it, add the below dependency to your project. ``` // build.gradle.kts implementation("androidx.fragment:fragment:1.7.0-alpha09") // build.gradle implementation 'androidx.fragment:fragment:1.7.0-alpha09' // build.gradle.kts with version catalogs: implementation(libs.fragment) # libs.versions.toml [versions] fragment = "1.7.0-alpha09" [libraries] fragment = { module = "androidx.fragment:fragment", version.ref = "fragment" } ``` 1.7.0-alpha09 is the version this documentation was generated from; there may be newer versions available. [Additional details about androidx.fragment:fragment](androidx_fragment_fragment.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("UnsafeRepeatOnLifecycleDetector") fun method() { repeatOnLifecycle(...) } ``` or ```java // Java @SuppressWarnings("UnsafeRepeatOnLifecycleDetector") void method() { repeatOnLifecycle(...); } ``` * Using a suppression comment like this on the line above: ```kt //noinspection UnsafeRepeatOnLifecycleDetector problematicStatement() ``` * 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="UnsafeRepeatOnLifecycleDetector" 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 'UnsafeRepeatOnLifecycleDetector' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore UnsafeRepeatOnLifecycleDetector ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
