i mentioned - first tap on input. then send text. better use your:

driver.findElements(AppiumBy.className("android.widget.EditText")).get(0).sendKeys("000000016");
// or
new Actions(driver).sendKeys(text).perform();
// deprecated in old versions (you did not said what you using)
// driver.getKeyboard().sendKeys(text);
