如何从adb shell触发“ Ok google”？

Question

我正在尝试从Android O（8.0）上的adb shell模拟“ Ok google”，但我找不到解决方案。

我发现在“ Ok google”之后显示的应用具有cmp=com.google.android.googlequicksearchbox/com.google.android.apps.gsa.staticplugins.opa.OpaActivity。但是，由于出现以下错误，我无法通过adb启动它。

$adb shell am start -n com.google.android.googlequicksearchbox/com.google.android.apps.gsa.staticplugins.opa.OpaActivity
Starting: Intent { cmp=com.google.android.googlequicksearchbox/com.google.android.apps.gsa.staticplugins.opa.OpaActivity }
Security exception: Permission Denial: starting Intent { flg=0x10000000 cmp=com.google.android.googlequicksearchbox/com.google.android.apps.gsa.staticplugins.opa.OpaActivity } from null (pid=29706, uid=2000) not exported from uid 10044

java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.google.android.googlequicksearchbox/com.google.android.apps.gsa.staticplugins.opa.OpaActivity } from null (pid=29706, uid=2000) not exported from uid 10044

我希望有一些解决方案可以通过adb启动上述应用。

• 避免$adb shell am start -n com.google.android.googlequicksearchbox/com.google.android.apps.gsa.staticplugins.opa.OpaActivity的安全异常
• 通过另一个adb命令

Answer 1

可能首先需要运行adb root

> adb root
> adb shell am start -n com.google.android.googlequicksearchbox/com.google.android.apps.gsa.staticplugins.opa.OpaActivity
