<br>
It looks like you are missing the "-android" option when replaying line2.<br>
<br>
Also, if you are using the most recent git version of PANDA, note that<br>
a recent change introduced a regression to the ARM record/replay<br>
support. If you roll back to commit 38e9caf ARM record/replay will<br>
work correctly. This issue is currently being tracked at<br>
<a href="https://github.com/moyix/panda/issues/91" rel="noreferrer" target="_blank">https://github.com/moyix/panda/issues/91</a> and we'll try to get it fixed<br>
soon.<br>
