There is a problem running droidbot analysis on Android emulator with Android4.1 and DroidBox system and ramdisk images.
The emulator receives SIGSEGV at some moment while exploring the application under analysis and then reboots breaking this way the droidbot traversal. The number of events sent to the emulator before the fail vary (usually it is 30-60 events). The error received also varies but typically it looks like that in adb logs:
For more information see the adb logs and droidbot command line output in test cases (issue.zip).
Most probably this error is not connected with droidbot exploration. The error is not seen when using emulator with original (not DroidBox-patched) system images and the same AVD.
In order to reproduce the error, get the old droidbot version working with DroidBox on https://github.com/nastya/droidbot/tree/droidbox
Here are the test cases. I used two applications downloaded from Google Play to get the logs describing the error: zok.android.letters.apk and com.alexcruz.papuhwalls_10.apk. Actually the choise of the applications does not matter, such emulator failures are seen every time.
Before running droidbot I started emulator with DroidBox-patched Android and after its boot finished I ran
adb logcat > *_logcat*.txtand the droidbot analysis.droidbot -d emulator-5554 -a test_apps/zok.android.letters.apk -o zok_out1 -use_with_droidbox -policy dfs -count 100 &> zok_log1.txtdroidbot -d emulator-5554 -a test_apps/zok.android.letters.apk -o zok_out2 -use_with_droidbox -policy dfs -count 100 &> zok_log2.txtWhen rerunning the analysis with -no_shuffle option the SIGSEGV happens almoast at the same time (see papuh* logs).
droidbot -d emulator-5554 -a test_apps/com.alexcruz.papuhwalls_10.apk -o papuh_out1 -use_with_droidbox -no_shuffle -policy dfs -count 100 &> papuh_log1.txtdroidbot -d emulator-5554 -a test_apps/com.alexcruz.papuhwalls_10.apk -o papuh_out2 -use_with_droidbox -no_shuffle -policy dfs -count 100 &> papuh_log2.txtThe same behavior is seen without using -use_with_droidbox option.
