3. Select **Android**. Skip 1 & 2.
4. Enter **your\_package\_name** in the package option and enter **your\_package\_name.MainActivity​** in the activity option.

```
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
```

{% endtab %}

{% tab title="WIndows" %}

```
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\USERNAME\.android\debug.keystore" | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" sha1 -binary | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" base64
```

{% endtab %}
{% endtabs %}

1. Use ​**android**​ as a debug password. After that, you will get a hash id like this.

1. For the **release hash id**, run the following command by replacing your **alias key** name and **Keystore location**. You can get these from your **a​ndroid/key.properties** ​file.

```
keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64
```

1. After that, you will get another **hash id**. Now, copy and paste them into the next steps of the Facebook developer site. Like this,

4. Now go to ​**android/app/src/main/res/values/strings.xml** file​ and change the **facebook\_app\_id** and **facebook\_client\_token**.
