Android开源，屏幕记录“ SIGBUS”

Question

1. Using Samsung Galaxy S6 ( @ v5.1.1 )
2. I have compiled Android OS 5.1.1_r33 in accordance to https://source.android.com/source/building.html ( aosp_arm-eng )
3. In specific I have compiled "screenrecord" ( and not the rest of the OS )
4. I have copied 'screenrecord' to '/data/local/tmp/' using adb push ( on the real device )
5. Lunching /data/local/tmp/screenrecord --verbose --bugreport /data/local/tmp/dump.mp4 is causing "Fatal signal 7 (SIGBUS), code 1, fault addr 0xf4c08e3f in tid 3263 (screenrecord)".
6. This doesn't happen w/ the built-in 'screenrecord', only w/ the one I manually compile.

This has properly worked w/ Android 5.0 @ Galaxy S5, and, is working on Android 6.0 @ Nexus 5 , what may be the problem? what might cause the crash?

Answer 1

Solution was simple

1. Samsung has it's own Android Flavor built upon Googles Android Open Source
2. Before building for Samsung the code base should be updated to support Samsung Flavor
3. Code base update is done by downloading Samsung's code @ http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=G920F
4. And adding it on to Googles Android code-base.
5. Build & deploy
