三星4.4.2＆QUOT调试本机应用程序;包不明＆QUOT;与运行的命令 [英] Debug native application on Samsung 4.4.2 "package is unknown" with run-as command
问题描述
在试图调试在银河S4通过Eclipse的Android原生应用程序，我得到一个包是未知的错误在运行的命令。
While trying to debug an Android native application via Eclipse on a Galaxy S4 i get a "package is unknown" error at the run-as command.
有一个开放的<一个href="https://$c$c.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=58373"相对=nofollow>问题为code.google.com ，指出它涉及到的权限问题 /data/system/packages.list 文件必须是 RW-RW - R的，而是是RW-RW ---- 。因此，在建议的解决方案是铲除手机和更改权限。
我已经植根于手机改变packages.list文件的权限 RW-RW - R的但是当我从Eclipse的权限启动调试本机应用程序被改回以 RW-RW ------- 。
There's an open issue at code.google.com that states the problem it's related to the permission of the /data/system/packages.list file that has to be rw-rw--r, instead it is rw-rw----. So, on of the suggested solution is to root the phone and change the permissions.
I' ve rooted the phone to change permissions of packages.list file to rw-rw--r but when I start "Debug as native Application" from eclipse permissions are changed back to rw-rw-------.
我该如何解决这个问题？我一定要闪回固件即使手机是植根？
How can I solve this? Do I have to flash back the firmware even if the phone is rooted?
推荐答案
我已经打破我的头几天如现在在这个问题上。 在写这篇文章的时候，我能够与Android 4.1.2上的三星手机调试本机code。不过三星的Galaxy S5采用Android 4.4.2面对不断给我：
I have been breaking my head for several days as well now on this issue. At the time of writing, I was able to debug native code on a Samsung phone with Android 4.1.2. However a Samsung Galaxy S5 with Android 4.4.2 keeps confronting me with:
gdbserver的输出：
gdbserver output:
运行方式：包'x.y.z'未知
run-as: Package 'x.y.z' is unknown
验证应用程序是否建有NDK_DEBUG = 1
Verify if the application was built with NDK_DEBUG=1
作为一个丑陋的解决方法，似乎可以更改的权限运行为从750到4750一个植根设备上;在Windows 7机器上：
As an "ugly" workaround, it seems possible to change the permissions of 'run-as' from 750 into 4750 on a rooted device; on a Windows 7 machine:
- 在使用USB连接设备到PC主机
- 打开主机上的命令提示符PC
- 进入Android的SDK文件夹的平台工具文件夹
- 执行亚行壳
- 在外壳中，执行命令搭配chmod 4750 /系统/斌/运行为
从理论上讲，这应该解决的问题。我无法然而，测试这个，因为我没有在时刻植根设备。 我会很高兴地看到，如果有人能实际测试这一点，并发布结果。的
Theoretically this should solve the problem. I'm unable to test this however as I don't have a rooted device at the moment. I would be happy to see if someone can actually test this and post a result.
