This gist explains how to send push notification locally using ADB without need network connection.

android-send-push-locally-using-adb.adoc

Requirements:

• Device should be a rooted (simulator’s are rooted by default)

• adbd should be started as root. (Rub command: adb root )

Now, send local push message using command:

adb shell am broadcast \
  -n com.your.app/com.google.firebase.iid.FirebaseInstanceIdReceiver \
  -a "com.google.android.c2dm.intent.RECEIVE" \
  --es "extra1" "65" \
  --es "guid" "1f400184-9215-479c-b19a-a9cd9a1d9dc9" \
  --es "extra3" "VALUE" \
  --es "extra4" "'Long string with spaces'"

What’s happening?

• Simply, using adb we are broadcasting message with parameters.

• adb shell am broadcast command that broadcasts.

• -n parameter for define component (see IntentSpec@ADB Documentation)

• We are broadcasting for com.google.firebase.iid.FirebaseInstanceIdReceiver, because we are using Firebase Messaging Service

• We are sending action -a com.google.android.c2dm.intent.RECEIVE because FirebaseInstanceIdReceiver defines this in AndroidManifest.xml file.

  • Also, this is why we need to be root. This action requires Signature level permission.

• We are adding extras with --es parameter.

Now, we can get data in onMessageReceived under the FirebaseMessagingService. When user taps notification remoteMessage.getData().get("extra1") should be return "65".
