Appium + Android + WebDriver findElement() : cannot find element after sendKeys()?

I have a simulated Android device and Appium. My test successfully launches the right Activity and types in a particular text field. But when I try to find the same text field in order to check the text in it, I get `"An element could not be located on the page using the given search parameters."` Even if I try to re-use the element instead of searching for it a second time, it still fails with the same message. What should I do differently? Maybe the context for the second `findElement()` is wrong -- I can't find the button next to the text field either. Here's a git repo that contains an app and a test project. The failed JUnit test demonstrates the issue: https://github.com/achengs/an-appium-question Details below (code and Appium log interleaved) Here's the first findElement which succeeds. The layout xml file for the Activity has this attribute for the text field that I'm looking for: `android:id="@+id/edit_message"` ``` public static final String MESSAGE_TO_SEND = "edit_message"; ... WebElement e = driver.findElement(By.id(MESSAGE_TO_SEND)); ``` First findElement succeeds: ``` debug: Appium request initiated at /wd/hub/session/0ec259be-87e0-47f6-9279-da577fe29a07/element debug: Request received with params: {"using":"id","value":"edit_message"} info: Pushing command to appium work queue: ["find",{"strategy":"id","selector":"edit_message","context":"","multiple":false}] info: [BOOTSTRAP] [info] Got data from client: {"cmd":"action","action":"find","params":{"strategy":"id","selector":"edit_message","context":"","multiple":false}} info: [BOOTSTRAP] [info] Got command of type ACTION info: [BOOTSTRAP] [debug] Got command action: find info: [BOOTSTRAP] [debug] Finding edit_message using ID with the contextId: info: [BOOTSTRAP] [info] Returning result: {"value":{"ELEMENT":"1"},"status":0} info: Responding to client with success: {"status":0,"value":{"ELEMENT":"1"},"sessionId":"0ec259be-87e0-47f6-9279-da577fe29a07"} POST /wd/hub/session/0ec259be-87e0-47f6-9279-da577fe29a07/element 200 5656ms - 109b ``` Saying hello! ``` String text = "hello!"; e.sendKeys(text); ``` That succeeds: ``` debug: Appium request initiated at /wd/hub/session/0ec259be-87e0-47f6-9279-da577fe29a07/element/1/value debug: Request received with params: {"id":"1","value":["hello!"]} info: Pushing command to appium work queue: ["element:setText",{"elementId":"1","text":"hello!"}] info: [BOOTSTRAP] [info] Got data from client: {"cmd":"action","action":"element:setText","params":{"elementId":"1","text":"hello!"}} info: [BOOTSTRAP] [info] Got command of type ACTION info: [BOOTSTRAP] [debug] Got command action: setText info: [BOOTSTRAP] [info] Returning result: {"value":true,"status":0} info: Responding to client with success: {"status":0,"value":true,"sessionId":"0ec259be-87e0-47f6-9279-da577fe29a07"} POST /wd/hub/session/0ec259be-87e0-47f6-9279-da577fe29a07/element/1/value 200 4215ms - 89b ``` Here's the second findElement which fails. (If I skip this findElement and re-use the original one -- or if I try to find the Send button next to the text field instead, I still get a similar failure) ``` WebElement f = driver.findElement(By.id(MESSAGE_TO_SEND)); ``` Here's the log for the failure: ``` debug: Appium request initiated at /wd/hub/session/0ec259be-87e0-47f6-9279-da577fe29a07/element debug: Request received with params: {"using":"id","value":"edit_message"} info: Pushing command to appium work queue: ["find",{"strategy":"id","selector":"edit_message","context":"","multiple":false}] info: [BOOTSTRAP] [info] Got data from client: {"cmd":"action","action":"find","params":{"strategy":"id","selector":"edit_message","context":"","multiple":false}} info: [BOOTSTRAP] [info] Got command of type ACTION info: [BOOTSTRAP] [debug] Got command action: find info: [BOOTSTRAP] [debug] Finding edit_message using ID with the contextId: info: [BOOTSTRAP] [info] Returning result: {"value":"No element found","status":7} info: Responding to client with error: {"status":7,"value":{"message":"An element could not be located on the page using the given search parameters.","origValue":"No element found"},"sessionId":"0ec259be-87e0-47f6-9279-da577fe29a07"} POST /wd/hub/session/0ec259be-87e0-47f6-9279-da577fe29a07/element 500 874ms - 223b ``` There was a request for the HTML. I'm testing a native Android app. Here's the layout xml for the current Activity under test. If there's something else I should include here, please do let me know. ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal"> <EditText android:id="@+id/edit_message" android:layout_weight="1" android:layout_width="0dp" android:layout_height="wrap_content" android:hint="@string/edit_message" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send" android:onClick="sendMessage" android:id="@+id/send"/> </LinearLayout> ```
