If you want to disable self-healing for specific findElement commands you can do this by changing the type of your driver object to the GptDriver class. This will enable you to set a selfHealing parameter on the findElement(s) methods to false. e.g. when you want to perform a strict check at the end of a test.
GptDriverAndroiddriver=newGptDriverAndroid(new java.net.URL("http://127.0.0.1:4723"), options);// second parameter disables self healingWebElementel=driver.findElement(By.id("successMessage"),false);Assert.assertTrue(el.isDisplayed());
Please take a look at the Reference for a more complete overview of the SDK capabilities.
