-s：指定产生随机事件种子值，相同的种子值产生相同的事件序列。如： -s 200
--throttle：每个事件结束后的间隔时间——降低系统的压力（如不指定，系统会尽快的发送事件序列）。如：--throttle 100
--pct-touch：指定触摸事件的百分比，如：--pct-touch 5% ， 相关的还有以下option：
--pct-motion <percent> （滑动事件）、 --pct-trackball <percent> （轨迹球事件） 、 --pct-nav <percent> （导航事件 up/down/left/right）、 --pct-majornav <percent> (主要导航事件 back key 、 menu key)、 --pct-syskeys <percent> (系统按键事件 Home 、Back 、startCall 、 endCall 、 volumeControl)、 --pct-appswitch <percent> （activity之间的切换）、 --pct-anyevent <percent>（任意事件）

4: Debug options

--dbg-no-events：初始化启动的activity，但是不产生任何事件。

--ignore-crashes：忽略崩溃
--ignore-timeouts：忽略超时
--ignore-security-exceptions：忽略安全异常
--kill-process-after-error：发生错误后直接杀掉进程
--monitor-native-crashes：跟踪本地方法的崩溃问题

5. A simple monkey command:

1	`adb shell monkey -p com.xy.android.junit -s 500 -v 10000`

Copy after login

However, in order to ensure the complete number of tests at work, we generally do not exit the stress test immediately when an error occurs. The monkey test command is as follows

1	`adb shell monkey -p com.xy.android.junit -s 500 --ignore-crashes --ignore-timeouts --monitor-native-crashes -v -v 10000 > E:\monkey_log\java_monkey_log.txt`

Copy after login

6. The package used by monkey: com.ckt.android.junit
The seed value for generating time series: 500
Ignore program crashes, ignore timeouts, and monitor local program crashes , the detail level is 2, and 10,000 events are generated.
