当我运行下面的 Java for Android 代码时，在 GetItemList 类的 doInBackground 方法中调用 getSkuDetails 的行上出现 NullPointerException。但是当我在调试器中逐步执行时，getSkuDetails 的所有参数都有值。 pName 不是空字符串，querySkus 中有两项。我收到的确切错误消息是“尝试调用接口(interface)方法‘android.os.Bundle com.android.vending.billing.IInAppBillingService.getSkuDetails(int, java.lang.String, java.lang.String, android.os .Bundle)' 在空对象引用上。”有谁知道为什么吗？

可能发生的情况是 ServiceConnection 连接类的 mServiceConn 实例需要一些时间才能连接，并且在建立连接之前，mService 保持为空。
要解决此问题，请尝试以下代码:
public class AvailableCards extends Activity {
IInAppBillingService mService;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_available_cards);
String packagename = this.getPackageName();
TextView priceView = (TextView)findViewById(R.id.availablePrice);
ServiceConnection mServiceConn = new ServiceConnection() {
@Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}
@Override
public void onServiceConnected(ComponentName name,
IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
new GetItemList(packagename, priceView).execute();
}
};
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.available_cards, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
class GetItemList extends AsyncTask<Integer, Integer, Long> {
private String pName;
private TextView pView;
GetItemList(String packagename, TextView priceView){
pName = packagename;
pView = priceView;
}
@Override
protected Long doInBackground(Integer... params) {
ArrayList<String> skuList = new ArrayList<String> ();
skuList.add("i001");
skuList.add("i002");
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST", skuList);
Bundle skuDetails = null;
try {
skuDetails = mService.getSkuDetails(3, pName, "inapp", querySkus);
int response = skuDetails.getInt("RESPONSE_CODE");
if (response == 0) {
ArrayList<String> responseList
= skuDetails.getStringArrayList("DETAILS_LIST");
for (String thisResponse : responseList) {
JSONObject object;
object = new JSONObject(thisResponse);
String sku = object.getString("productId");
String price = object.getString("price");
String mFirstIntermediate;
String mSecondIntermediate;
if (sku.equals("i001")) mFirstIntermediate = price;
else if (sku.equals("i002")) mSecondIntermediate = price;
pView.setText(sku + ": " + price);
}
}
} catch (NullPointerException ne) {
Log.d("Synch Billing", "Error Null Pointer: " + ne.getMessage());
ne.printStackTrace();
}
catch (RemoteException e) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error Remote: " + e.getMessage());
e.printStackTrace();
}
catch (JSONException je) {
// TODO Auto-generated catch block
Log.d("Synch Billing", "Error JSON: " + je.getMessage());
je.printStackTrace();
}
return null;
}
}

我早就知道Ruby中的“常量”(即大写的变量名)不是真正常量。与其他编程语言一样，对对象的引用是唯一存储在变量/常量中的东西。(侧边栏:Ruby确实具有“卡住”引用对象不被修改的功能，据我所知，许多其他语言都没有提供这种功能。)所以这是我的问题:当您将一个值重新分配给常量时，您会收到如下警告:>>FOO='bar'=>"bar">>FOO='baz'(irb):2:warning:alreadyinitializedconstantFOO=>"baz"有没有办法强制Ruby抛出异常而不是打印警告？很难弄清楚为什么有时会发生重新分配。 最佳答案
