4.0.4 设备将在没有 --user 选项的情况下成功启动服务器,但会失败。4.2.1 设备需要 --user 选项并且没有它会失败。
如何以适用于所有 Android 设备的方式启动服务?
或者如果不可能,确定何时需要 --user 的标准是什么?
$ adb shell getprop ro.build.version.release
4.0.4
$ adb shell am startservice --user 0 -ei 123 -a com.a.activity.myservice
Error: Unknown option: --user
usage: am [subcommand] [options]
{ usage info deleted
$ adb shell getprop ro.build.version.release
4.2.1
$ adb shell am startservice -ei 123 -a com.a.activity.myservice
Starting service: Intent { act=com.a.activity.myervice (has extras) }
~/dev/dcf/Applications/Spin (master) $ adb shell am startservice -ei 123 -a com.a.activity.myservice
Starting service: Intent { act=com.apportable.a.myservice (has extras) }
