适用于IInAppBillingService.getSkuDetails的AndroidNull指针异常的Java

当我运行下面的JavaforAndroid代码时,我在GetItemList类的doInBackground方法中调用getSkuDetails的行上得到NullPointerEx

当我运行下面的Java for Android代码时,我在GetItemList类的doInBackground方法中调用getSkuDetails的行上得到NullPointerException.但是当我在调试器中单步执行时,getSkuDetails的所有参数都有值. pName不是空字符串,querySkus中有两个项目.我得到的确切错误消息是“尝试调用接口方法”android.os.Bundle com.android.vending.billing.IInAppBillingService.getSkuDetails(int,java.lang.String,java.lang.String,android.os .Bundle)’对空对象引用.“有谁知道为什么？

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 { private String pName; private TextView pView; GetItemList(String packagename, TextView priceView){ pName = packagename; pView = priceView; } IInAppBillingService mService; 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); } }; @Override protected Long doInBackground(Integer... params) { ArrayList skuList = new ArrayList (); 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 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; } }

解决方法:

可能发生的是ServiceConnection连接类的mServiceConn实例需要一些时间来连接,并且在建立连接之前,mService保持为null.

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 { private String pName; private TextView pView; GetItemList(String packagename, TextView priceView){ pName = packagename; pView = priceView; } @Override protected Long doInBackground(Integer... params) { ArrayList skuList = new ArrayList (); 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 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; } }
