(#) Missing MEDIA_PLAY_FROM_SEARCH intent-filter !!! ERROR: Missing MEDIA_PLAY_FROM_SEARCH intent-filter This is an error. Id : `MissingIntentFilterForMediaSearch` Summary : Missing MEDIA_PLAY_FROM_SEARCH intent-filter Severity : Error Category : Correctness Platform : Android Vendor : Android Open Source Project Feedback : https://issuetracker.google.com/issues/new?component=192708 Since : 1.5.0 (November 2015) Affects : Kotlin and Java files, manifest files and resource files Editing : This check runs on the fly in the IDE editor See : https://developer.android.com/training/auto/audio/index.html#support_voice 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/AndroidAutoDetector.java) 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/AndroidAutoDetectorTest.java) To support voice searches on Android Auto, you should also register an `intent-filter` for the action `android.media.action.MEDIA_PLAY_FROM_SEARCH`. To do this, add ```xml `` `` `` ``` to your `` or ``. (##) Example Here is an example of lint warnings produced by this check: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text AndroidManifest.xml:6:Error: Missing intent-filter for action android.media.action.MEDIA_PLAY_FROM_SEARCH. [MissingIntentFilterForMediaSearch] <application ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here are the relevant source files: `AndroidManifest.xml`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" package="com.example.android.uamp"> <application android:name=".UAMPApplication" android:label="@string/app_name" android:theme="@style/UAmpAppTheme"> <meta-data android:name="com.google.android.gms.car.application" android:resource="@xml/automotive_app_desc"/> <service android:name=".MusicService" android:exported="true" tools:ignore="ExportedService"> <intent-filter> <action android:name="android.media.browse.MediaBrowserService"/> </intent-filter> </service> </application> </manifest> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ `res/xml/automotive_app_desc.xml`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers <?xml version="1.0" encoding="utf-8"?> <automotiveApp> <uses name="media"/> </automotiveApp> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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/AndroidAutoDetectorTest.java) 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, `AndroidAutoDetector.testMissingMediaSearchIntent`.

(##) Suppressing You can suppress false positives using one of the following mechanisms: * Adding the suppression attribute `tools:ignore="MissingIntentFilterForMediaSearch"` 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"> ... <automotiveApp tools:ignore="MissingIntentFilterForMediaSearch" .../> ... </manifest> ``` * Using a suppression annotation like this on the enclosing element: ```kt // Kotlin @Suppress("MissingIntentFilterForMediaSearch") fun method() { problematicStatement() } ``` or ```java // Java @SuppressWarnings("MissingIntentFilterForMediaSearch") void method() { problematicStatement(); } ``` * Using a suppression comment like this on the line above: ```kt //noinspection MissingIntentFilterForMediaSearch 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="MissingIntentFilterForMediaSearch" 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 'MissingIntentFilterForMediaSearch' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore MissingIntentFilterForMediaSearch ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
