我如何与And​​roid应用程序运行的valgrind？ [英] How do I run valgrind with an Android app?

问题描述

我已经为Android安装Valgrind的，我可以证实，它正在为我试着用它运行LS，并能正常工作。

I've installed valgrind for android and I can confirm it is working as I tried running ls with it, and it works fine.

但我怎么执行与本机组件一个Android应用程序，我想调试？我看了看这个问题：如何下手的valgrind一个Android应用程序，但我不知道如何遵循它。你如何包装在一个shell脚本的应用程序？什么是包装。其次应该是包的名字？

But how do I execute an android app with a native component I would like to debug? I looked at this question: How to start an android app with valgrind but I have no idea how to follow it. How do you wrap an app in a shell script? What is "wrap." followed by the package name supposed to be?

我试着这样做与com.matthewmitchell.wakeifyplus是我的应用程序包：

I tried doing this with com.matthewmitchell.wakeifyplus being my application package:

setprop wrap.com.matthewmitchell.wakeifyplus "logwrapper /data/local/valgrind" 

但它说：无法设置属性。我应该做些什么？我找不到一步的指导，工程的任何步骤。我也试试这个（我甚至不知道什么setprop一样）：

but it says "could not set property". What am I supposed to do? I can't find any step by step guide that works. I did try this (I don't even know what setprop does):

setprop com.matthewmitchell.wakeifyplus "logwrapper /data/local/valgrind" 

使用/数据/本地/ Valgrind的是一个shell脚本执行权限是：

With /data/local/valgrind being a shell script with execute permissions which is:

#!/system/bin/sh
VGPARAMS='--error-limit=no'
export TMPDIR=/data/data/com.matthewmitchell.wakeifyplus
exec /data/local/Inst/bin/valgrind $VGPARAMS $*

但是当我运行的应用程序：

But when I run the app with:

am start -a android.intent.action.MAIN -n com.matthewmitchell.wakeifyplus/.MainActivity 

的valgrind不会在logcat中显示出来，即使清理后。

valgrind does not show up in logcat, even after clearing it.

推荐答案

您得到错误无法设置属性，因为您不能设置属性名的长度大于31 ，这是在属性名的数量最大允许的字符： http://stackoverflow.com/a/5068818/313113

You get the error "could not set property" because you CANNOT set a property name with a length greater than 31, which is the number maximum allowed characters in the property name: http://stackoverflow.com/a/5068818/313113

尽量减少当您设置与亚行的shell setprop财产少于或等于31个字符的包名称的长度。
和使用bash脚本简单的事情。

Try to reduce the package name length to less than or equal 31 characters when you set the property with adb shell setprop.
And use a bash script to simply things.
