How to start/stop a service from adb in Android

androidtips

This article will introduce how to start or stop a service from adb in Android.

1. Start a service by "adb shell am start-service"

The adb shell am start-service <Intent> command can be used to launch a service for the given Intent.

Intents can be defined as an option in a command. For more detailed settings, please refer to the "Reference: Intent Setting Options" at the bottom of the article.

1.1 start a service in the foreground

You can run the service in the foreground with the following command.

$ adb shell am start-foreground-service <Intent>

2. Stop a service by "adb shell am stop-service"

The following command will stop the running service.

$ adb shell am stop-service <Intent>

3. Example: Start an Intent with only Action

If you define an intent with the -a option after the adb shell am start command, an intent with only the Action will be started.

$ adb shell am start-service -a android.intent.action.MY_ACTION

Output:

Starting service: Intent { act=android.intent.action.MY_ACTION }

4. Example: Start an Intent with Action and Category

You can add a Category using the -c option.

If there are two categories, you can enter them multiple times like -c AAA -c BBB.

$ adb shell am start-service -a android.intent.action.MY_ACTION -c android.intent.category.MY_CATEGORY

5. Example: Start an Intent with Action and Data

If you input a Uri with the -d option, an Intent with the data of the Uri will be executed.

$ adb shell am start-service -a android.intent.action.MY_ACTION -d https://google.com

6. Example: Start an Intent with Action and Package

You can start an Intent with the -p option set to the Package.

$ adb shell am start-service -a android.intent.action.MY_ACTION -p com.example.myapp

7. Example: Start an Intent with Action, Package and Component

You can start an Intent with the -n option set for the Package and Component.

$ adb shell am start-service -a android.intent.action.MY_ACTION -n com.example.myapp/com.example.myapp.MyService
