I'm working on automated tests for an Android app which loads content from a web database. Since the connection and result from the database may take some time, I tried to use the following code to wait until a button (which only appears when content is loaded) is visible.
WebDriverWait wait = new WebDriverWait(driver, 60);
wait.until(ExpectedConditions.visibilityOf(driver.findElementById(ID))).click();
With driver being instantiated as AndroidDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
When I run the test that uses this code, I get the following error:
java.lang.NoSuchMethodError: org.openqa.selenium.support.ui.WebDriverWait.until(Lcom/google/common/base/Function;)Ljava/lang/Object;

Does someone know what is the problem? I already added Guava 21.0 and 24.1-Android to Maven XML file, but neither of them changed anything in the results.
It might be a chicken-and-egg thing, since instead of checking for the existence of the element, you're assuming that it's in the DOM but not visible. I would advise checking to see if it exists instead.
You could instead do a loop using findElements():
while (true) {
if (driver.findElements(By.id("com.oi.codigital:id/main_refresh_button")).size() == 0)
break;
}
