无法使用 Valgrind 运行 Java Android 程序 [英] Can't run a Java Android program with Valgrind
问题描述
我正在尝试在 Valgring 下像这样(在 adb shell 中)启动一个 Java 程序:
I'm trying to start a Java program under Valgring like this (in adb shell):
valgrind am start -a android.intent.action.MAIN -n com.me.myapp/.MainActivity
我得到:
==2362== Memcheck, a memory error detector
==2362== Copyright (C) 2002-2012, and GNU GPL'd, by Julian Seward et al.
==2362== Using Valgrind-3.8.1 and LibVEX; rerun with -h for copyright info
==2362== Command: am
==2362==
/system/bin/sh: am: No such file or directory
推荐答案
你必须创建一个脚本,我们称之为 start_valgrind.sh
You have to create a script, lets call it start_valgrind.sh
#!/system/bin/sh
PACKAGE="com.example.hellojni"
# Callgrind tool
#VGPARAMS='-v --error-limit=no --trace-children=yes --log-file=/sdcard/valgrind.log.%p --tool=callgrind --callgrind-out-file=/sdcard/callgrind.out.%p'
# Memcheck tool
VGPARAMS='-v --error-limit=no --trace-children=yes --log-file=/sdcard/valgrind.log.%p --tool=memcheck --leak-check=full --show-reachable=yes'
export TMPDIR=/data/data/$PACKAGE
exec /data/local/Inst/bin/valgrind $VGPARAMS $*
应该复制到设备上.
一旦您在本地文件系统上的 start_valgrind.sh 文件中拥有上述脚本,您就可以使用以下脚本(我们称之为 bootstrap_valgrind.sh)来完成所有工作(将 start_valgrind.sh 脚本复制到手机,运行它,通过 Valgrind 启动您的应用).
Once you have the above script in the start_valgrind.sh file somewhere on your local filesystem you can just use the below script (lets call it bootstrap_valgrind.sh) to do the all the work (copies the start_valgrind.sh script to the phone, runs it, starts your app through Valgrind).
#!/usr/bin/env bash
PACKAGE="com.example.hellojni"
adb push start_valgrind.sh /data/local/
adb shell chmod 777 /data/local/start_valgrind.sh
adb root
adb shell setprop wrap.$PACKAGE "logwrapper /data/local/start_valgrind.sh"
echo "wrap.$PACKAGE: $(adb shell getprop wrap.$PACKAGE)"
adb shell am force-stop $PACKAGE
adb shell am start -a android.intent.action.MAIN -n $PACKAGE/.HelloJni
adb logcat -c
adb logcat
exit 0
警告:确保使用 setprop 设置的属性名称,即 (wrap.com.yourcompany.yourapp) 的长度小于 31 个字符.
否则,您将收到错误无法设置属性",因为您不能设置长度大于 31 的属性名称,这是属性名称中允许的最大字符数.
此外,属性值应为 <= 91 个字符:https://stackoverflow.com/a/5068818/313113
