Question

我有以下代码（app live，我在mService.consumePurchase的行中报告了崩溃）：

Thread trd = new Thread(new Runnable()
{
      @Override
      public void run()
      {
          try
          {
                int response = mService.consumePurchase(3, getPackageName(), sku.mToken);
                if (response == 0)
                {
                    System.out.println("onActivityResult consume ok");
                    purchasesOK.add(sku.mSku);
                }
                else
                {
                    System.out.println("onActivityResult consume failed");
                    purchasesFail.add(sku.mSku);
                    runOnUiThread(new Runnable()
                    {
                         public void run() 
                         {
                            alert("Store Problems!", "There were problems consuming the product, please use RESTORE button.");
                         }
                    });
                }
          } catch (RemoteException e) {
              purchasesFail.add(sku.mSku);
                System.out.println("onActivityResult consume crashed");
                runOnUiThread(new Runnable()
                {
                     public void run() 
                     {
                     alert("Store Problems!", "There were problems consuming the product, please use RESTORE button.");
                     }
                });
            }
     }
});
trd.start();

这是崩溃报告：

java.lang.NullPointerException at com.XXXXX.GGActivity.j_ItemPurchase（GGActivity.java:1309）at at com.XXXXX.GGLib.step（Native Method）at com.XXXXX.GGView $ Renderer.onDrawFrame（GGView.java:436）at at android.opengl.GLSurfaceView $ GLThread.guardedRun（GLSurfaceView.java:1523）在android.opengl.GLSurfaceView $ GLThread.run（GLSurfaceView.java:1240）

我认为try / catch会在任何异常情况下显示弹出错误。什么可能导致它的想法？或者我该如何避免呢？

谢谢， / C

添加：

catch(NullPointerException e){
    purchasesFail.add(sku.mSku);
    System.out.println("onActivityResult consume crashed");
    runOnUiThread(new Runnable(){
        public void run(){
            alert("Store Problems!", "There were problems consuming the product, please use RESTORE button.");
        }
    });
}

以显示弹出消息

在try / catch里面的Android java.lang.NullPointerException
