enforceXPath1 | boolean | Since UiAutomator2 driver version `4.25.0` XPath2 is set as the default and the recommended interpreter for the corresponding element locators. This interpreter is based on [Psychopath XPath2](https://wiki.eclipse.org/PsychoPathXPathProcessor) implementation, which is now a part of the Eclipse foundation. In most of the cases XPath1 locators are also valid XPath2 locators, so there should be no issues while locating elements. Although, since the XPath2 standard is much more advanced in comparison to the previous version, some [issues](https://github.com/appium/appium/issues/16142) are possible for more sophisticated locators, which cannot be fixed easily, as we depend on the third-party library mentioned above. Then try to workaround such issues by enforcing XPath1 usage (whose implementation is a part of the Android platform itself) and assigning this setting to `true`. Note, this setting is actually applied at the time when the element lookup by XPath is executed, so you could switch it on or off whenever needed throughout your automated testing session.

limitXPathContextScope | boolean | Due to historical reasons UiAutomator2 driver limits scopes of element context-based searches to the parent element. This means a request like `findElement(By.xpath, "//root").findElement(By.xpath, "./..")` would always fail, because the driver only collects descendants of the `root` element for the destination XML source. The `limitXPathContextScope` setting being set to `false` changes that default behavior, so the collected page source includes the whole page source XML where `root` node is set as the search context. With that setting disabled the search query above should not fail anymore. Although, you must still be careful while building XPath requests for context-based searches with the `limitXPathContextScope` setting set to `false`. A request like `findElement(By.xpath, "//root").findElement(By.xpath, "//element")` would ignore the current context and search for `element` trough the whole page source. Use `.` notation to correct that behavior and only find `element` nodes which are descendants of the `root` node: `findElement(By.xpath, "//root").findElement(By.xpath, ".//element")`.

disableIdLocatorAutocompletion | boolean | According to internal Android standards it is expected that each resource identifier is prefixed with `<packageName>:id/` string. This should guarantee uniqueness of each identifier. Although some application development frameworks ignore this rule and don't add such prefix automatically or, rather, let it up to the developer to decide how to represent their application identifiers. For example, [testTag modifier attribute in the Jetpack Compose](https://developer.android.com/reference/kotlin/androidx/compose/ui/platform/package-summary#(androidx.compose.ui.Modifier).testTag(kotlin.String)) with [testTagsAsResourceId](https://developer.android.com/reference/kotlin/androidx/compose/ui/semantics/package-summary#(androidx.compose.ui.semantics.SemanticsPropertyReceiver).testTagsAsResourceId()) allows developers to set an arbitrary string without the prefix rule. [Interoperability with UiAutomator](https://developer.android.com/jetpack/compose/testing) also explains how to set it. By default UIA2 driver adds the above prefixes automatically to all resource id locators if they are not prefixed, but in case of such "special" apps this feature might be disabled by assigning the setting to `true`.

alwaysTraversableViewClasses | string | Allows to continue the tree traversal for user defined classes even though the node itself is invisible. The default logic for the UI tree traversal (controlled by the `allowInvisibleElements` setting) is to stop recursing when an invisible node is found. However, with certain Jetpack Compose classes (e.g. androidx.compose.ui.viewinterop.ViewFactoryHolder), it is possible that invisible parent nodes have visible child nodes. See [Google issue \#354958193](https://issuetracker.google.com/issues/354958193) and [UIA2 server issue \#709](https://github.com/appium/appium-uiautomator2-server/issues/709) for more details. This setting only affects the XPath lookup and the page source buildup. You can provide a comma separated list of glob patterns, that will be used as an exemption list: `androidx.compose.ui.viewinterop.*,android.widget.ImageButton`. Available since the driver version 5.0.3.

includeExtrasInPageSource | boolean | Whether to include `extras` element attribute in the XML page source result. Then, XPath locator can find the element by the extras. Its value consists of combined [getExtras](https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo#getExtras()) as `keys=value` pair separated by a semicolon (`;`), thus you may need to find the element with partial matching like `contains` e.g. `driver.find_element :xpath, '//*[contains(@extras, "AccessibilityNodeInfo.roleDescription=")]'`. The value could be huge if elements in the XML page source have large `extras`. It could affect the performance of XML page source generation.
338339
includeA11yActionsInPageSource | boolean | Whether to include `actions` element attribute in the XML page source result. Its value consists of names of available accessibility actions from [getActionList](https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo#getActionList()), separated by a comma. The value could be huge if elements in the XML page source have a lot of actions and could affect the performance of XML page source generation.

snapshotMaxDepth | int | The number of maximum depth for the source tree snapshot. The default value is `70`. This number should be in range [1, 500]. A part of the elements source tree might be lost if the value is too low. Also, StackOverflowError might be caused if the value is too high (Issues [12545](https://github.com/appium/appium/issues/12545), [12892](https://github.com/appium/appium/issues/12892)). The available driver version is `2.27.0` or higher.

currentDisplayId | int | The id of the display that should be used when finding elements, taking screenshots, etc. It can be found in the output of `adb shell dumpsys display` (search for `mDisplayId`). The default value is [Display.DEFAULT_DISPLAY](https://developer.android.com/reference/android/view/Display#DEFAULT_DISPLAY). See the [Multi-Window Testing Guide](docs/android-multiwindow.md) for detailed information about windows, displays, and how this setting affects element location. Set this setting to `-1`
