strace
You can use strace on Android. It is included in the Android open source project (at least as of Android 2.1), and appears to be automatically installed in engineering builds of the software.
To use strace during early initialization, you can put it in the /init.rc file. For example, to trace zygote initialization, change the following line in /init.rc.
service zygote /system/bin/app_process -Xzygote /system/bin --zygote --start-system-server
should be changed to:
service zygote /system/xbin/strace -tt -o/data/boot.strace /system/bin/app_process -Xzygote /system/bin --zygote --start system-server
