   appium_lib: { sauce_username: nil, sauce_access_key: nil } }
driver = Appium::Driver.new(caps).start_driver

sleep 10

driver.find_element(:xpath,'//android.support.v7.widget.LinearLayoutCompat/android.widget.TextView').click
driver.find_element(:xpath,'//android.widget.EditText[@resource-id="com.tencent.mm:id/gz"]').send_keys("浙江移动");
sleep 2
