Appium locators don't work with saucelabs Android -

i have ui component:

<button             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="fire event"             android:id="@+id/fireevent"             android:layout_below="@+id/buttonviewkruxwebpage"             android:layout_alignparentleft="true"             android:layout_alignparentstart="true"             android:layout_margintop="43dp" /> 

and want find using appium id locator: driver.findelement(by.id("fireevent")). works fine locally appium cannot find on saucelabs. locally , remotely on sauselabs both cases have appium 1.4.0. have tried variant of lacator:
driver.findelement(by.id("com.example.package:id/txtlogin"))

how long wait element appear in findelement method? possible saucelabs has bigger delays suggest increase time-outs , see happens.
