Android GoogleMaps V2 MarkerDemo IllegalStateException没有包括点: 我正在为GoogleMaps V2创建MarkerDemo的自定义实现。我有一个奇怪的错误，我将LatLng值提供给LatLngBounds.Builder实例，然后将其作为变量传递给.build。当我通过Eclipse在调试模式下运行应用程序时，Map会加载。当我通过Eclipse正常运行时，会抛出一个带有“no included points”的IllegalStateException作为消息。有人可以帮忙吗？这是一些协助的代码。 public class MyActivity extends android.support.v4.app.FragmentActivity implements OnMarkerClickListener, OnInfoWindowClickListener, OnMarkerDragListener { private HashMap<DataItem, ArrayList> mUserLocations = new HashMap<DataItem, ArrayList>(); private ArrayList mFeedData; private NetworkingHandler mHandler = new NetworkingHandler(“tag”); private GoogleMap mMap; private final String DOWNLOAD_USER_LOCATIONS_URL = “http://www.myfeedurllocation.com/page.php”; @Override public void onCreate(Bundle savedBundleInstance) { super.onCreate(savedBundleInstance); setContentView(R.layout.activity_myactivitylayout); downloadUserLocations(); setUpMapIfNeeded(); […]

什么是IllegalStateException？: 我正在尝试使用以下Fastload API 连接…等是完美的。我确切地知道它失败了 ……….. System.out.println(” Streaming ” + dataFile); pstmtFld.setAsciiStream(1, dataStream, -1); // This line fails System.out.println(“check the above line”); // This does not go to console ……….. 例外是 Exception in thread “main” java.lang.IllegalStateException: Sample failed. [ODBC Teradata Driver] Invalid precision: cbColDef value out of range 这是我要上传的表格。它是.csv格式，当我通过记事本打开它时，它看起来像这样 1,9,Win 2,9,Winc 3,9,Wi 为什么我会得到这个例外？我怎样才能改进它？据我所知，问题是pstmtFld.setAsciiStream(1, […]

更清洁的方式来获得原型的自动assembly字段的新实例: 我遇到了这个问题，同时尝试自动运行一个可运行的类，并在不同的调用中创建它的不同实例并将其保存在数组中。 xml配置是：在我的代码中，我正在尝试这样的事情： public class ThreadHandler{ @Autowired private ABC threadName; //getter ABC getThreadName(){ return threadName; } public void someFunction(){ List abc = new ArrayList(ABC>(); for (int i=0;i<SOME_CONST;i++){ ABC tName = getThreadName(); abc.add(tName); tName.start(); } } } 让ABC成为一个Thread/Runnable/Callable 。这样，它抛出java.lang.IllegalThreadStateException 。但是，它工作正常，如果我使用ABC tName =appContext.getBean(“threadName”,ABC.class); 为什么会这样？在尝试从getMethod获取对象时，我们不会获得新实例吗？

Google Play游戏: 今天是个好日子。我正在尝试在我正在开发的游戏中实现成就。我已经在google play console上设置了所有内容，获得了app-id，将清单放入以下内容中并编写了以下方法 GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance(); int temp = googleApiAvailability.isGooglePlayServicesAvailable(this); if ( temp != 0) return; GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN) .requestEmail() .build(); GoogleSignIn.getClient(this, gso); GoogleSignInAccount account = GoogleSignIn.getLastSignedInAccount(this); PlayersClient player = Games.getPlayersClient(this, account); 当我运行它时，我得到了我的帐户，但是当它运行Games.getPlayersClient(this, account); 我收到以下错误： java.lang.IllegalStateException：游戏API需要https://www.googleapis.com/auth/games_litefunction。任何人都知道什么可能是错的？提前致谢。
