Is there a unique Android device ID? 40 answers

Try this :

    String deviceId = Secure.getString(this.getContentResolver(),
            Secure.ANDROID_ID);
    Toast.makeText(this, deviceId, Toast.LENGTH_SHORT).show();

android.provider.Settings.Secure.ANDROID_ID

A 64-bit number (as a hex string) that is randomly generated on the device's first boot and should remain constant for the lifetime of the device.

Note : The value may change if a factory reset is performed on the device.

Hope this helps.

Try this:

TelephonyManager TM = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

// IMEI No.
String imeiNo = TM.getDeviceId();

// IMSI No.
String imsiNo = TM.getSubscriberId();

// SIM Serial No.
String simSerialNo  = TM.getSimSerialNumber();

// Android Unique ID
String androidId = Settings.Secure.getString(this.getContentResolver(),Settings.Secure.ANDROID_ID);

Don't forget to add

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

to your manifest file.

尝试这个：

Secure.getString(getContext().getContentResolver(), Secure.ANDROID_ID);
