2. click "news"
3. select one news
4. When it finish loading, press back
5. repeat 2~4 steps continuously.
[Result]

I attached the

At first, we suspect two points. 1. JIT and 2.JavaScript.
Therefore, we disable JavaScript and JIT and let Monkey to test
Browser. The following are my modifications.
1. Disable JIT
path: android/packages/app/Browser/AndroidManfest.xml
>android:vmSafeMode="true"
2. Forbid Monkey to change JS setup
path: android/framework/base/core/java/android/webkit/WebSetting.java
> public synchronized void setJavaScriptEnabled(boolean flag) {
> boolean isMonkey = SystemProperties.getBoolean("ro.monkey", false);
> if (mJavaScriptEnabled != flag && isMonkey != true) {
> mJavaScriptEnabled = flag;
> postSync();
> }
> }
3. disable JavaScript and let monkey run
3.1 launch browser
3.2 press "menu" button ->"more"-> "Settings" -> uncheck "Enable
JavaScript"
3.3 execute the monkey. The following is my command
# adb.exe shell setprop ro.monkey true
# adb.exe shell "monkey -p com.android.browser -s 2 --ignore-
crashes --ignore-timeouts --ignore-security-exceptions --kill-
process-after-error --monitor-native-crashes -v -v --throttle 1000
2000000 > /sdcard/Monkey_log.txt"
As disabling JavaScript and JIT, Browser is still crashed. So
far, is there any good suggestion or idea, or does anyone meet the
same problem? Thanks for your reading and I will really appreciate
your suggestion or idea.
Best Regards,
Wayne Lin
