(#) TargetSdkVersion No Longer Supported !!! ERROR: TargetSdkVersion No Longer Supported 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 : `ExpiredTargetSdkVersion` Summary : TargetSdkVersion No Longer Supported Severity : Fatal Category : Compliance Platform : Android Vendor : Android Open Source Project Feedback : https://issuetracker.google.com/issues/new?component=192708 Since : 3.2.0 (September 2018) Affects : Gradle build files and manifest files Editing : This check runs on the fly in the IDE editor See : https://support.google.com/googleplay/android-developer/answer/113469#targetsdk See : https://developer.android.com/distribute/best-practices/develop/target-sdk.html Implementation : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-checks/src/main/java/com/android/tools/lint/checks/GradleDetector.kt) Tests : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/GradleDetectorTest.kt) Configuring your app or sdk to target a recent API level ensures that users benefit from significant security and performance improvements, while still allowing your app to run on older Android versions (down to the `minSdkVersion`). To update your `targetSdkVersion`, follow the steps from "Meeting Google Play requirements for target API level", https://developer.android.com/distribute/best-practices/develop/target-sdk.html. !!! Tip This lint check has an associated quickfix available in the IDE. (##) Example Here is an example of lint warnings produced by this check: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text build.gradle:5:Error: Google Play requires that apps target API level 31 or higher. [ExpiredTargetSdkVersion] targetSdkVersion 17 ------------------- build.gradle:6:Error: Google Play requires that apps target API level 31 or higher. [ExpiredTargetSdkVersion] targetSdk 17 ------------ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here is the source file referenced above: `build.gradle`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~groovy linenumbers apply plugin: 'com.android.application' android { defaultConfig { targetSdkVersion 17 targetSdk 17 } } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can also visit the [source code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/GradleDetectorTest.kt) for the unit tests for this check to see additional scenarios. The above example was automatically extracted from the first unit test found for this lint check, `GradleDetector.testExpiring1`. To report a problem with this extracted sample, visit https://issuetracker.google.com/issues/new?component=192708. (##) Suppressing You can suppress false positives using one of the following mechanisms: * Using a suppression comment like this on the line above: ```kt //noinspection ExpiredTargetSdkVersion problematicStatement() ``` * Adding the suppression attribute `tools:ignore="ExpiredTargetSdkVersion"` 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"`. * 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="ExpiredTargetSdkVersion" 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 'ExpiredTargetSdkVersion' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore ExpiredTargetSdkVersion ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
