Android Device Id Guide

Learn how to create a good device identifier

Pushlink Start

As you may have noticed, the last Pushlink.start parameter is "yourDeviceId".

PushLink.start(this, R.mipmap.ic_launcher, "yourApiKey", "yourDeviceID");

It's up to you to identify the device.

Disclaimer

There is no default and 100% guaranteed way to retrieve the Device ID on Android. It depends on the OS version, device brand, etc. That's why Pushlink externalizes the id generation.

However, Pushlink is designed for enterprise apps, and the developers usually control which types of Devices and OS the application will run. Don't use an ID that is changed after every uninstall/install. Try to use a long-live ID. Think and create your strategy.

What should I be alert?

Be careful with non-certified ROMs.

• Fake IMEI like '004999010640000'.

• Fake Settings.Secure.ANDROID_ID like '9774d56d682e549c'.

Be careful with Android releases. They frequently change permissions and behaviors related to device identifiers.

What happens if I set the same ID on different devices?

Don't do that. You will not be able to manage your installations properly. This will create all sorts of problems.

What happens if my device ID changes frequently?

One real-life installation will be registered many times, giving you an unreal number of managed devices.
