无法从Google的IAB框架中捕获IllegalstateException

我有一个使用 In App Billing V3框架。

谷歌游戏 Developer Console 报告频繁的崩溃 java.lang.IllegalStateException

事实上,我的大多数崩溃都是这种非法状态的例外。我使用IAB框架中的示例代码来处理我的应用内购买。

调用堆栈:

  at com.steenriver.armor.util.IabHelper.flagStartAsync (IabHelper.java:824)
  at com.steenriver.armor.util.IabHelper.queryInventoryAsync (IabHelper.java:616)
  at com.steenriver.armor.util.IabHelper.queryInventoryAsync (IabHelper.java:644)
  at com.steenriver.armor.ArmorActivity$1.onIabSetupFinished (ArmorActivity.java:185)
  at com.steenriver.armor.util.IabHelper$1.onServiceConnected (IabHelper.java:262)
  at android.app.LoadedApk$ServiceDispatcher.doConnected (LoadedApk.java:1625)
  at android.app.LoadedApk$ServiceDispatcher$RunConnection.run (LoadedApk.java:1653)
  at android.os.Handler.handleCallback (Handler.java:836)
  at android.os.Handler.dispatchMessage (Handler.java:103)
  at android.os.Looper.loop (Looper.java:232)
  at android.app.ActivityThread.main (ActivityThread.java:6802)
  at java.lang.reflect.Method.invoke (Native Method)
  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run (ZygoteInit.java:1103)
  at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:964)

为了避免崩溃,我决定向代码中添加异常处理,如下所示:

try
{
    mHelper.launchPurchaseFlow( this, sku, RC_REQUEST, mPurchaseFinishedListener, payload );
} catch( IllegalStateException e )
{
    Log.e( TAG, e.toString() );     // Illegal State: maybe purchase is already in progress?
    enableBuyButton();              // Enable buy button so customer can try again.
}

令我惊讶的是,添加了try/catch的新版本仍然使用相同的调用堆栈崩溃。

这是因为根本无法抓住非法状态例外,还是什么原因?这是怎么回事?
