嗨我知道我之前发过同样的问题，但似乎无法找到正确的方法。 如果联系人有任何更改，这是我的类，由服务调用。值得注意的是，该服务不断调用，可能导致内存泄漏，不确定。
以下是服务类的代码：
public class ContactsSyncService extends Service {
public static int count =0;
int k = 0;
public static boolean contactUpdated = false;
ContentObserver mObserver;
public Context contextService = ContactsSyncService.this;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
mObserver = new ContentObserver(new Handler()) {
@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
k++;
if (!contactUpdated)
{
contactUpdated = true;
Logger.debug("Contact Update to start -->");
FetchLocalContacts.refreshingContactsDB();
}
}
};
getContentResolver().registerContentObserver(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, true, mObserver);
return START_NOT_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
getContentResolver().unregisterContentObserver(mObserver);
}
}
这是导致内存泄漏的类：

答案 0 :(得分：0)
你的realmFresh.close()由if (phones.getCount() > 0)保护，所以如果你的getCount() == 0你不会关闭王国并泄漏内存。您是否尝试将close（）方法移到if语句之外？
