Selendroid : Element not Found and refering to element id that i did not pass

Question

Hi I am using selendroid to test my app but I am getting an error in that the element id is not found, and the id displayed in error is not passed by me anywhere in my code.

Following is the trace of TestNG log:

org.openqa.selenium.StaleElementReferenceException: The element with id '749f7f36-cf23-cf8a-3ba4-089302016ab6' was not found.

I am adding code for the driver and test exception is happening at recharge_btn id

private SelendroidDriver driver;
    @BeforeClass
        public void setUp() throws Exception {
            SelendroidConfiguration config = new SelendroidConfiguration();
            config.addSupportedApp("myapp.apk");
    //      SelendroidLauncher selendroidServer = new SelendroidLauncher(config);
    //      selendroidServer.launchSelendroid();
            capa = new SelendroidCapabilities("in.myapp:2.3");
            // capa.setAut("io.selendroid.testapp:0.15.0");
            // capa.setPlatformVersion(DeviceTargetPlatform.ANDROID19);
            capa.setEmulator(false);
            driver = new SelendroidDriver(capa);
        }
@Test
    public void bRechargePrepaid() throws Exception {
//      driver = new SelendroidDriver(capa);
        System.out.println("Starting Prepaid Recharge");
        driver.get(PREPAID_RECHARGE_ACTIVITY);
        // WebElement rechargeList = driver.findElement(By.linkText("Prepaid"));
        // rechargeList.click();

//      File file = new File("D:/prepaidRecharge.txt");
//      fr = new FileReader(file);
//      br = new BufferedReader(fr);
//      String fileLine = "";
//      try {

                WebElement element = driver.findElement(By
                        .id("mobile_number_edit"));
                element.sendKeys("9780325188");
                element = driver.findElement(By.id("amount_edit"));
                element.clear();
                element.sendKeys("100");
                element = driver.findElement(By.id("edt_operator"));
                element.click();
                element = driver
                        .findElement(By.linkText("VODAFONE"));
                element.click();
                Thread.sleep(2000);
                element = driver.findElement(By.id("recharge_btn"));
                element.click();
                element = driver.findElement(By.id("button1"));
                element.click();
                Thread.sleep(15000);
                driver.navigate().back();

//          }
//      } finally {
//          br.close();
//          fr.close();
//      }

        Thread.sleep(10000);
