Re: [Valgrind-users] Valgrind + Android

[Matthew M. <mat...@th...>]

Is it not possible to restart zygote with zalgrind? I'm trying to debug an app using the NDK. I don't know if the NDK library is loaded and executed in the zygote process? If so I guess I have a similar problem.

In the init.rc file on android zygote is started as:

service zygote /system/bin/app_process -Xzygote /system/bin --zygote --start-system-server

I suppose that could be changed to start zygote by valgrind instead? This would run valgrind for all apps though.

Matthew.
