How do I fix the "Invalid Credentials" error for Android push notifications?

The "Invalid Credentials" error indicates a configuration problem, usually caused by a mismatch in settings (such as IDs or keys) between your Firebase project and the configuration in your Pushwoosh account or application.

To resolve this, please follow these steps:

1. Verify Your Firebase Configuration

First, check for any recent changes in your Firebase console. Ensure that the credentials used in the following places are all correct, consistent, and belong to the same Firebase project:

• The google-services.json file in your app.
• The Firebase private key uploaded to Pushwoosh.
• The AndroidManifest.xml file of your app.

Often, this error occurs if a key or ID from a different Firebase project was used by mistake.

2. Re-configure the Android Platform in Pushwoosh

Update your configuration in the Pushwoosh Control Panel to ensure it matches your Firebase project.

1. Log in to your Pushwoosh account and select your application.
2. Navigate to the Android platform configuration section.
3. Re-upload your current Firebase private key.

3. Generate New Credentials (If Necessary)

If the issue persists after verifying the existing credentials, generating new ones can often resolve the problem.

1. In your Firebase project, generate a new google-services.json file and add it to your application.
2. Create a new Firebase private key.
3. Upload the new private key to your Android platform configuration in the Pushwoosh Control Panel.
