I have been spending a lot of time using the common opinion about the correct capability that solves this problem.
On Java:
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("credentials_enable_service", false);
prefs.put("profile.password_manager_enabled", false);
options.setExperimentalOption("prefs", prefs);
Or this other:
options.addArguments("--disable-save-password-bubble");
And never worked fine for me.
System configuration:
I solved the problem and not is a capability. I align the system configuration with that:
It seems is important the apk version on emulator and the ChromeDriver version appium are using.
I'm using this capabilities:
ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-extensions", "test-type",
"no-default-browser-check", "ignore-certificate-errors",
"--disable-notifications",
"--disable-offer-store-unmasked-wallet-cards",
"--disable-autofill-keyboard-accessory-view");
options.addArguments("--disable-translate");
