Ensures that an actions XML file is properly formed.
!!! 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
res/xml/my_actions.xml:1:Error: This action resource should be
registered in the manifest under the tag as [ValidActionsXml]
<actions>
-------
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Here are the relevant source files:
`src/AndroidManifest.xml`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.helloworld"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="15" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".HelloWorld"
android:label="@string/app_name">
</activity>
</application>
</manifest>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`res/xml/my_actions.xml`:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~xml linenumbers
<actions>
<action intentName="name1">
<fulfillment urlTemplate="foo"/>
</action>
</actions>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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, `ActionsXmlDetector.testMissingManifestRegistration`.

(##) Suppressing
You can suppress false positives using one of the following mechanisms:
* Adding the suppression attribute `tools:ignore="ValidActionsXml"` 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="ValidActionsXml" 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 'ValidActionsXml'
}
```
In Android projects this should be nested inside an `android { }`
block.
* For manual invocations of `lint`, using the `--ignore` flag:
```
$ lint --ignore ValidActionsXml ...`
```
* Last, but not least, using baselines, as discussed
[here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
