Question

I\'ve been searching for the last week trying to find an answer to this question.

How do I start an Android app with valgrind? I know I can start an app with the \'

Answer 1

You can try to clear the logcat first

prompt# adb logcat -c
prompt# adb logcat

You should be able to see the logs coming in once you triggered your application.

am start -a android.intent.action.MAIN -n com.example.hellojni/.HelloJni

I had problems with my shell script and i used this instead.

adb shell setprop wrap.com.example.hellojni "logwrapper /data/local/Inst/bin/valgrind"

You should be able to pass in the parameter right after valgrind

Answer 2

I encountered this problem too. In my situation, I edit the "val.sh" in windows & adb push it to the emulator, but the shell script could not be executed correctly. Then I use a echo "*" > val.sh style to make the "val.sh" and It works well.

So you should first make sure the "val.sh" could be interpreted correctly.

Answer 3

yes, but you should use

adb shell setprop wrap.com.example.hellojni "logwrapper ./data/local/Inst/bin/valgrind"
/\----for shell (.) is important!!!

also if you wish to use some configure of valgrind tool's - use this:

adb shell setprop wrap.com.example.hellojni "logwrapper ./data/local/Inst/bin/valgrind --tool=massif (...configure massif a.t.c. ...)"
