大家好，我现在碰到一个问题。在测试 apk（暂命名为 A 应用）时，运行到第 4 行代码后应用就会自动退出了，然后在运行第 4 行代码后报错：定位不到元素。下面是我的 java 代码。
系统：win7.
appium 版本：1.3.4（之前 用 1.3.7 也这样）
java:1.7

public void testApp() throws Exception {
        1， driver.findElementById("com.wacai365:id/etAccount").sendKeys("hys1990");
        2， driver.findElementById("com.wacai365:id/password").sendKeys("123456");
        3， Thread.sleep(1000);
        4， driver.findElementById("com.wacai365:id/billInfo").click();
        5， Thread.sleep(1000);
        6， driver.findElementById("android:id/action_bar_title").click();
        7， Thread.sleep(1000);
}

1，在自带的模拟器和 genymotion 上都是如此。不过我安装到 genymotion 上时报错，将 x86 处理器换成 atm 后就安装成功了。这个是否有影响？
2，是否开发 apk 时，会对这种登录的情况做一些限制，导致我的脚本运行就直接退出？

不知道大家有没有碰到过这种运行到一半，应用自动退出的情况。
