## Android Setup

1. You have to configure some stuff for Google sign-in. Go to the Google Cloud Console.

> Google Cloud Console: <https://console.cloud.google.com/apis/credentials/consent?project=travel-hour-252505>

2. Make sure you are signed in with the same account with which you have created the Firebase project. Also, make sure that on the top-left corner, your project is selected for which you are filling this consent.

5. In all these places, you have to enter the same link starting with **https\://** then your app domain name which I have marked with green below.
6. Then, scroll down and fill in the Application Homepage link, Application Privacy Policy link, and Application Terms of Services link.

7. Save the form by clicking on the Save button.

### Generate Debug Certificate

* To generate a debug certificate, run this command on your terminal from your app

  root directory.

{% tabs %}
{% tab title="Mac" %}

```
keytool -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore
```

{% endtab %}

{% tab title="Windows" %}

```
keytool -list -v \
-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
If this command doesn’t work, then go to this [link](https://developers.google.com/android/guides/client-auth) and copy the debug command from there according to your os.
{% endhint %}

* Use ​**android** as a debug password when the terminal asks for a password.

* Copy the **SHA1** certificate code and go to **Firebase Console > Your Project > Project Settings** and click on the android icon and then add the **SHA1** code by clicking ​**add fingerprint​** button. Look at the picture below:

### Generate Release Certificate

To generate a release certificate,

* Run with replacing your **alias\_name** and **keystore\_location**.

```
keytool -list -v -keystore keystore_location -alias alias_name
```

{% hint style="info" %}
Your alias\_name is **upload** and keystore\_location is the path(directory) of the **upload-keystore.jks** file.
{% endhint %}

* After that, you will get a **SHA1** code. Copy that code and add it to your **Firebase Console > Project Settings >  Android**, where you previously added a debug SHA1 code.
