我的应用中有一项功能，限制每台设备的购买量为1。 我使用以下代码为每台设备生成一个唯一的ID。当用户从Parallel Space App安装应用程序时，如何生成不同的代码。无论如何我能跟踪吗？
我的代码用于生成唯一ID：
public String getUniqueDeviceId() {
String deviceID = null;
String androidID = sessionManager.getUniqueID().get("uniqueid");
if(androidID!=null)
{
if(androidID.length()>0)
{
return androidID;
}
else
{
String uniqueId = "";
//TelephonyManager TelephonyMgr = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);
//uniqueId = uniqueId.concat(TelephonyMgr.getDeviceId());
String buildParams = "99" +
Build.BOARD.length() % 10 + Build.BRAND.length() % 10 +
Build.CPU_ABI.length() % 10 + Build.DEVICE.length() % 10 +
Build.DISPLAY.length() % 10 + Build.HOST.length() % 10 +
Build.ID.length() % 10 + Build.MANUFACTURER.length() % 10 +
Build.MODEL.length() % 10 + Build.PRODUCT.length() % 10 +
Build.TAGS.length() % 10 + Build.TYPE.length() % 10 +
Build.USER.length() % 10;
uniqueId = uniqueId.concat(buildParams);
uniqueId = uniqueId.concat(Settings.Secure.getString(getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID));
WifiManager wm = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
uniqueId = uniqueId.concat(wm.getConnectionInfo().getMacAddress());
// BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
// uniqueId = uniqueId.concat(mBluetoothAdapter.getAddress());
// Initiate digest with MD5
MessageDigest mDigest = null;
try {
mDigest = MessageDigest.getInstance("MD5");
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
mDigest.update(uniqueId.getBytes(), 0, uniqueId.length());
byte[] digestedBytes = mDigest.digest();
String deviceId = "";
for (int i = 0; i < digestedBytes.length; i++) {
int b = (0xFF & digestedBytes[i]);
// Additional Padding
if (b <= 0xF) {
deviceId += "0";
}
// concat at the end
deviceId = deviceId.concat(Integer.toHexString(b));
}
deviceID = deviceId.substring(0, 24);
sessionManager.createUniqueID(deviceID);
return deviceID;
}
}
else
{
String uniqueId = "";
//TelephonyManager TelephonyMgr = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);
//uniqueId = uniqueId.concat(TelephonyMgr.getDeviceId());
String buildParams = "99" +
Build.BOARD.length() % 10 + Build.BRAND.length() % 10 +

Build.MODEL.length() % 10 + Build.PRODUCT.length() % 10 +
Build.TAGS.length() % 10 + Build.TYPE.length() % 10 +
Build.USER.length() % 10;
uniqueId = uniqueId.concat(buildParams);
uniqueId = uniqueId.concat(Settings.Secure.getString(getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID));
WifiManager wm = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
uniqueId = uniqueId.concat(wm.getConnectionInfo().getMacAddress());
// BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
// uniqueId = uniqueId.concat(mBluetoothAdapter.getAddress());
// Initiate digest with MD5
MessageDigest mDigest = null;
try {
mDigest = MessageDigest.getInstance("MD5");
} catch (NoSuchAlgorithmException e) {

mDigest.update(uniqueId.getBytes(), 0, uniqueId.length());

return deviceID;
}
