Disconnect from Google Fit

Disconnecting from Google Fit revokes all granted OAuth permissions for your app and removes all recording subscriptions and sensor registrations made by your app.

You need to provide users with a Disconnect from Google Fit option in your app settings. When users select this option, you can call the ConfigClient.disableFit method to disable Google Fit:

KotlinJava

Fitness.getConfigClient(this,  GoogleSignIn.getAccountForExtension(this, fitnessOptions))
    .disableFit()
    .addOnSuccessListener {
        Log.i(TAG,"Disabled Google Fit")
    }
    .addOnFailureListener { e ->
        Log.w(TAG,"There was an error disabling Google Fit", e)
    }

Fitness.getConfigClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions))
        .disableFit()
        .addOnSuccessListener(unused ->
            Log.i(TAG, "Disabled Google Fit"))
        .addOnFailureListener(e ->
            Log.w(TAG, "There was an error disabling Google Fit", e));
