Android adb shell am broadcast: Bad component name

问题

I am trying to 'emulate' a reboot (or anything else with the adb shell am) and am unable to figure out how to reference my component. Then again, maybe I don't even understand what is meant by a component. Below I first include a few example commands that don't work, then my manifest. Note that StartupReceiver is successfully called when the 'phone' boots. I just want to re-trigger it without a full reboot.

Failed ADB commands:

$ ./adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n net.fstab.checkit_android.StartupReceiver
<help snipped>
Error: Bad component name: net.fstab.checkit_android.StartupReceiver

$ ./adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n .StartupReceiver
<help snipped>
Error: Bad component name: .StartupReceiver

$ ./adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n StartupReceiver
<help snipped>
Error: Bad component name: StartupReceiver

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

回答1:

You need to specify the package name before the class name (then you may write it without the package) like this:

./adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n net.fstab.checkit_android/.StartupReceiver

Practically it turns out that you just have to add a slash after the package name.

You helped me start, I helped you finish :)

回答2:

Broadcast does not require specify any Receiver. This case, please just stroke

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

Hope this help.

回答3:

Some apps may misbehave if BOOT_COMPLETED is received twice, instead limit broadcast to your app only:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -p com.example.package

回答4:

Try

adb shell am broadcast \ -a android.intent.action.BOOT_COMPLETED \ -n net.fstab.checkit_android/.StartupReceiver

(note the -n net.fstab.checkit_android/.StartupReceiver) to aim at a specific receiver.

Also make sure your app uses permission to receive specific broadcast intents - in this case it would be

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
