android - sh 脚本文件中的 am cmd 不起作用

Question

sh 文件如下所示

#!/system/bin/sh
am start -a android.intent.action.MAIN -n com.android.settings/.Settings
echo hello,world
exit 1

但它报告错误

Starting: Intent { act=android.intent.action.MAIN cmp=com.android.settings/.Sett
}gs
Error type 3
} does not exist.lass {com.android.settings/com.android.settings.Settings
hello,world
exit: Illegal number: 1

但是当我直接在 sh shell 中输入它时，比如在 adb shell 提示符中，输入am start -a android.intent.action.MAIN -n com.android.settings/.Settings，它可以工作，并运行 activty

所以有什么问题？

我刚试过你的脚本，它显然有效。也用过 2.3.3

echo "#!/system/bin/sh" >a.sh
#echo "#!/system/bin/sh" >a.sh
#cat a.sh
#!/system/bin/sh
# echo "am start -a android.intent.action.MAIN -n com.android.settings/.Settings" >>a.sh
echo "am start -a android.intent.action.MAIN -n com.android.settings/.Settings" >>a.sh
# cat a.sh
cat a.sh
#!/system/bin/sh
am start -a android.intent.action.MAIN -n com.android.settings/.Settings
# echo "echo hello, world" >>a.sh
echo "echo hello, world" >>a.sh
# echo "exit 0" >>a.sh
echo "exit 0" >>a.sh
# cat a.sh
cat a.sh
#!/system/bin/sh
am start -a android.intent.action.MAIN -n com.android.settings/.Settings
echo hello, world
exit 0   
# chmod 755 a.sh
chmod 755 a.sh
# ./a.sh
./a.sh
Starting: Intent { act=android.intent.action.MAIN cmp=com.android.settings/.Settings }
hello, world  
# cat /proc/cpuinfo
