如何绕过为 AlarmManager 设置唯一 ID？

UUID uuid = UUID.randomUUID();
String uniqueId = uuid.toString();

String packageName = getPackageName();
String userId = "123456";
long timestamp = System.currentTimeMillis();
String uniqueId = packageName + userId + timestamp;

String packageName = getPackageName();
String userId = "123456";
long timestamp = System.currentTimeMillis();
String combined = packageName + userId + timestamp;
String uniqueId = hash(combined);

private static final AtomicInteger uniqueId = new AtomicInteger(0);

String id = Integer.toString(uniqueId.getAndIncrement());

SharedPreferences sharedPreferences = getSharedPreferences("AlarmManager", MODE_PRIVATE);
int uniqueId = sharedPreferences.getInt("uniqueId", 0) + 1;
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putInt("uniqueId", uniqueId);
editor.apply();
String uniqueIdString = Integer.toString(uniqueId);
