Nvidia's gdb is better: http://developer.download.nvidia.com/tegra/files/tegra-gdb-20100430.zip | Nvidia's gdb is better: http://developer.download.nvidia.com/tegra/files/tegra-gdb-20100430.zip | ||
In order to attach before things get running, launch with: | |||
adb shell am start -a org.mozilla.gecko.DEBUG -n org.mozilla.fennec/org.mozilla.fennec.App | |||
and just click launch once gdb is attached. If you need to debug a crash that happens before XRE_Main is called, the patch on {{bug|572247}} may be useful. | |||
===Env Vars=== | |||
If you need to set and env var at run time, use append --es env# VAR=VAL to your activity manager command where # is the ordered number of variables for example: | |||
adb shell am start -a android.activity.MAIN -n org.mozilla.fennec/org.mozilla.fennec.App --es env0 VAR=val --es env1 FOO=bar | |||
You may need {{bug|578493}} if the env var you're using is tested before XRE_Main is called | |||
===PR Logging=== | ===PR Logging=== | ||
You can use the env vars as described above to make logging work (along with {{bug|578493}}. With just that you can log to a file | |||
adb shell am start -a android.activity.MAIN -n org.mozilla.fennec/org.mozilla.fennec.App --es env0 NSPR_LOG_MODULES=all:5 --es env1 NSPR_LOG_FILE=/mnt/sdcard/log.txt | |||
With the patch on {{bug|578496}} you can have the logging directed to the android logs and as such only need: | |||
adb shell am start -a android.activity.MAIN -n org.mozilla.fennec/org.mozilla.fennec.App --es env0 NSPR_LOG_MODULES=all:5 | |||
