====== Eindeutige ID eines Android-Gerätes ====== **DEPRECATED** //Bitte alternative Methode weiter unten verwenden//\\ Um eine eindeutige ID eines Android-Gerätes zu ermitteln, kann folgendes Code-Snippet genutzt werden: import java.util.UUID; private static String getUniquePsuedoID() { // If all else fails, if the user does have lower than API 9 (lower // than Gingerbread), has reset their phone or 'Secure.ANDROID_ID' // returns 'null', then simply the ID returned will be solely based // off their Android device information. This is where the collisions // can happen. // Thanks http://www.pocketmagic.net/?p=1662! // Try not to use DISPLAY, HOST or ID - these items could change. // If there are collisions, there will be overlapping data String m_szDevIDShort = "35" + (android.os.Build.BOARD.length() % 10) + (android.os.Build.BRAND.length() % 10) + (android.os.Build.CPU_ABI.length() % 10) + (android.os.Build.DEVICE.length() % 10) + (android.os.Build.MANUFACTURER.length() % 10) + (android.os.Build.MODEL.length() % 10) + (android.os.Build.PRODUCT.length() % 10); // Thanks to @Roman SL! // http://stackoverflow.com/a/4789483/950427 // Only devices with API >= 9 have android.os.Build.SERIAL // http://developer.android.com/reference/android/os/Build.html#SERIAL // If a user upgrades software or roots their phone, there will be a duplicate entry String serial; try { serial = android.os.Build.class.getField("SERIAL").get(null).toString(); // Go ahead and return the serial for api => 9 return new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString(); } catch (Exception e) { // String needs to be initialized serial = "bewa"; // some value } // Thanks @Joe! // http://stackoverflow.com/a/2853253/950427 // Finally, combine the values we have found by using the UUID class to create a unique identifier return new UUID(m_szDevIDShort.hashCode(), serial.hashCode()).toString(); } Eine alternative Variante, welche die Android ID ausliest sieht so aus: import android.provider.settings; public class RequestHelper { public static String getAndroidID(Context context) { return Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID); } }
