(#) Incompatible setRequestedOrientation value !!! WARNING: Incompatible setRequestedOrientation value This is a warning. Id : `SourceLockedOrientationActivity` Summary : Incompatible setRequestedOrientation value Severity : Warning Category : Correctness Platform : Android Vendor : Android Open Source Project Feedback : https://issuetracker.google.com/issues/new?component=192708 Since : 3.6.0 (February 2020) Affects : Kotlin and Java files Editing : This check runs on the fly in the IDE editor See : https://developer.android.com/guide/topics/large-screens/large-screen-cookbook#restricted_app_orientation 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/ChromeOsSourceDetector.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/ChromeOsSourceDetectorTest.kt) The `Activity` should not be locked to a portrait orientation so that users can take advantage of the multi-window environments and larger landscape-first screens that Android runs on such as ChromeOS, tablets, and foldables. To fix the issue, consider calling `setRequestedOrientation` with the `ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR` or `ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED` options or removing the call all together. !!! 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 src/test/pkg/MainActivity.java:15:Warning: You should not lock orientation of your activities, so that you can support a good user experience for any device or orientation [SourceLockedOrientationActivity] setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); ----------------------------------------------------------------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here is the source file referenced above: `src/test/pkg/MainActivity.java`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~java linenumbers package test.pkg; import android.app.Activity; import android.content.pm.ActivityInfo; import android.os.Bundle; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); } } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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/ChromeOsSourceDetectorTest.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, `ChromeOsSourceDetector.testInvalidSetRequestedOrientation`. 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 annotation like this on the enclosing element: ```kt // Kotlin @Suppress("SourceLockedOrientationActivity") fun method() { setRequestedOrientation(...) } ``` or ```java // Java @SuppressWarnings("SourceLockedOrientationActivity") void method() { setRequestedOrientation(...); } ``` * Using a suppression comment like this on the line above: ```kt //noinspection SourceLockedOrientationActivity 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="SourceLockedOrientationActivity" 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 'SourceLockedOrientationActivity' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore SourceLockedOrientationActivity ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
