在Linux中使用"execve“来运行android模拟器的进程，但是"avd”路径是错误的？

Question

我遇到了一个关于运行android模拟器的问题，下面是详细信息。非常感谢!

/*initailize passed command line\*/

char *binary = (char*)malloc(8*sizeof(char));  
char **newargv = (char **)malloc(16*sizeof(char *));

newargv[0] = "/media/career/android/source/out/host/linux-x86/sdk/android-sdk_eng.corey_linux-x86/tools/emulator";  
newargv[1] = "-avd";

newargv[2] = "new1";

newargv[3] = "-system";

newargv[4] = "/media/career/android/source/out/target/product/generic/system.img";

newargv[5] = "-ramdisk";

newargv[6] = "/media/career/android/source/out/target/product/generic/ramdisk.img";

newargv[7] = "-data";

newargv[8] = "/media/career/android/source/out/target/product/generic/userdata.img";

newargv[9] = NULL;        

/*initialize the env value of new process(emulator) */

const char *temp = getenv("ANDROID_AVD_HOME");

envp[0] = temp;

envp[1] = getenv("PATH");

envp[2] = NULL;

/*main function*/
if (execve (binary, (char **)newargv, (char **)envp) < 0 )  

environment variable:
declare -x ANDROID_AVD_HOME="/home/corey/.android/avd"
declare -x PATH="/media/career/android/source/out/host/linux-x86/sdk/android-sdk_eng.corey_linux-x86/platform-tools:/media/career/android/source/out/host/linux-x86/sdk/android-sdk_eng.corey_linux-x86/tools:

控制台显示：PANIC: Could not open: /tmp/.android/avd/new1.ini

我的avd存储路径默认是~/.android/avd。但是新的进程只找到根文件系统的路径，用于读取可移植性差的avd文件。实际上，模拟器的进程已经运行了。我专注于设置环境变量，但失败了。

请问我应该如何设置我的环境变量？

您传递了错误的envp

const char *temp = getenv("ANDROID_AVD_HOME");
envp[0] = "ANDROID_AVD_HOME=" + temp;
envp[1] = "PATH=" + getenv("PATH");
envp[2] = NULL;

用安全策略替换+
