Android Monkey scripting and checking for memory leaks

One, monkey script to write 1.Monkey script format

• Scripting Benefits:

Simple and fast, no need to touch any tools, only need a Notepad file

• Scripting Disadvantages:

Corresponding steps for basic operations such as coordinates, keystrokes, and sequential scripts are not logical

3.Monkey Script Instance

• Open Browser, enter www.baidu.com, test 10 times

#头文件, controlling the parameters of the monkey sending message type=Raw Eventscount=Ten Speed=1.0#一下为脚本正文start Data>>#1. Open Browser launchactivity (com.android.browser,com.android.browser.browseractivity) profilewait () #2. Clear the URL tap (223,146) profilewait () dispatchpress ( the) profilewait () #3. Enter URL dispatchstring (www.baidu.com) profilewait () #4confirm, load URL dispatchpress (keycode_enter) profilewait () #5. Complete Exit browser dispatchpress (Keycode_home) profilewait () #6After the script completes, push the. txt file to the phone, and then use the command"adb shell monkey-f path/name.txt--throttle 500-v-V 1"Command debug run, where path refers to the file storage path, name refers to the filename

Second, monkey server

1) Open the phone port using the command "ADB shell Monkey–port 1080"
2) connect the PC and mobile port using the command "ADB forward tcp:1080 tcp:1080"
3) Create a communication using the command "telnet localhost 1080"

• #注意事项：

 the adb forward TCP:  tcp: +/////Windows does not have Telnet turned on by default, Control Panel--programs and features--turn on or off the Windows feature--telnet related all tick ok then restart the computer

Iii. monkey Checking for memory leaks 1. Analyzing memory leaks tools and commands

1) hprof file: Hprof can monitor CPU usage, heap allocation statistics
2) Mat tool: (http:www.eclipse.org/mat/)
3) Generate hprof File command: "ADB shell am dumpheap < process name > < save path >"
4) View app Memory command: "adb shell Dumpsys meminfo < process name >"
5) Convert to Mat readable file directive: "Hprof-conv < original hprof file path > < converted hprof file path >"

2. Basic Operation steps

1) Run Monkey or fixed automation use cases
2) Monitor the memory value and save the Hprof file if there is a large increment exception
3) Convert the saved hprof file into a mat readable file
4) Use the mat to open files and compare and analyze multiple files

3. Example

• Android Spin screen creates a memory leak

1) Enter the URL "http:www.eclipse.org/mat/" in the links below the page click Download, and then in the new page select the appropriate system to download, download and then unzip it.
2) Prepare a script for the. bat suffix name to view the memory in real time, with the following script code:

 set  process=com.android.browser #需要测试的 Process name @adb Shell Dumpsys meminfo %process% | findstr  pss   " %process% | findstr  total   "  @ping -n 5  127.1  >nul@goto m  

3) Use the Monkey command in the cmd window "adb shell monkey-p com.android.browser–pct-rotation 100–throttle 2000-v 20"
4) Open the previously prepared. bat file to monitor the application memory situation
5) After monkey run, use the command "adb shell am dumpheap com.android.browser/data/local/tmp/test.hprof" to save the results
6) Save the. hprof file to the local PC "adb pull/data/local/tmp/test.hprof F:\test"
7) under F:\test path shift+ right mouse button to open cmd window input command "Hprof-conv test.hprof test1.hprof"
8) Use the downloaded Mat.exe to open the converted Test1.hprof file for viewing analysis (using the command "SELECT * from instanceof android.app.Activity to view objects in the database, the more objects the more memory leaks the more serious)
