Synopsis: an open source project to provide a universal and persistent
Unique Device IDentifier (UDID) solution for Android
Major Changes:
- (*new) added usage of cross-application shared preferences in PackageContext to feature ensuare consistency of UDID
- make sure the UDID is consistent across application
- allow using least permission
- clearly indicate the source of UDID, e.g. IMEI:/WIFIMAC:/BTMAC:/ANDROID:
- provide enough fail back for Android2.2 device with invalid ANDROID_ID, no phone, no WiFi, no BlueTooth enviroment
- include a demo project (the project works for android 1.6+ without BT and 2.1+ with BT)
- add the concept of internal UDID which protect privacy, make it harder for 3rd party to identify your users' devices
Usage:
* in OpenUDID.java , configure the values
private final static boolean _UseImeiFailback = true;// false if you don't wanna include READ_PHONE_STATE permission
//we recommend adding BT permission over READ_PHONE_STATE permission as the will be less privacy concerns
private final static boolean _UseBlueToothFailback = true; // false if you don't wanna include BT permission or android 1.6
* selectively add this to your manifest:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<!-- if BlueTooth is used--> <uses-permission android:name="android.permission.BLUETOOTH"/>
<!-- if IMEI is used--> <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
* Call void OpenUDID.syncContext(getApplicationContext()); ///to initialize the OpenUDID
// this version is synchronous
* Call `String OpenUDID.getOpenUDIDInContext();` to retrieve your OpenUDID
* Call `String OpenUDID.getCorpUDID(String corpIdentifier);` to retrieve your internal UDID (suggested corpIdentifier can be domain or java package name like com.wavespread)
