# How to find my Installation ID on an Android device?

Usually, using the Custom User ID is the easiest way to locate your device on Batch and register yourself as a tester on the platform.

However, this identifier isn't always available in Batch:

* It's usually only set for logged-in users.
* You may not know your Custom User ID.

This is why Batch created the **Installation ID**. This ID is unique and is generated when the application is installed.

{% hint style="danger" %}
The Installation ID is renewed every time the app is uninstalled/reinstalled.
{% endhint %}

You can retrieve your Installation ID following the methods below:

## Option A: Use the "Find my installation" feature <a href="#h_6121f721eb" id="h_6121f721eb"></a>

From version 1.18 of our SDK, Batch will copy the Installation ID to the clipboard when the application appears in the foreground 4 times within 20 seconds.

Here is how to do it:

{% stepper %}
{% step %}
Close your application (from the background)

{% endstep %}

{% step %}
Reopen it and switch to the background 4 times in a row in less than 20 seconds

{% endstep %}

{% step %}
Open a clipboard and paste the text: this is your Installation ID!
{% endstep %}
{% endstepper %}

You can also follow the video below:&#x20;

{% hint style="warning" %}
If you use an older version of the SDK or if you have deactivated this feature via [our dedicated method](https://doc.batch.com/developer/sdk/ios/troubleshooting#copying-the-installation-id), we recommend displaying the Installation ID somewhere in the app: [Displaying the installation ID](https://doc.batch.com/developer/sdk/ios/troubleshooting#displaying-the-installation-id).

\
If it hasn't been done, you'll still be able to find your Installation ID following the option detailed below.
{% endhint %}

## Option B: Check the logs in the terminal application <a href="#h_6121f721eb" id="h_6121f721eb"></a>

To do so, please refer to our documentation on [how to check Batch logs on Android](https://doc.batch.com/developer/technical-guides/how-to-guides/mobile/android-specific/how-to-check-batch-logs-on-android).
