Android 无法绑定(bind)到服务(在 App-Billing 中)

Question

我正在尝试在我的应用程序中实现应用计费，但我遇到了一点问题。我正在使用来自 Android 开发人员网站的示例，每次我启动将连接到计费服务的 Activity 时，它都会向我显示一个我无法连接到服务器的对话框，当我按下“了解更多”时，它将转到一个解释我的网页更新我的安卓市场应用程序，但它已经是最新的了。另一方面，在我的应用程序上实现代码之前，我创建了一个测试应用程序，我可以在其中连接相同的代码并且我没有遇到问题。但是在我的应用程序中我不能那样做。是否与开发人员 api key 有任何联系，您只能在一个应用程序或类似的应用程序中使用它。因为我对测试应用和真实应用使用相同的应用。

这里是我的代码，如果你能看到一些不应该的东西:

            builder.setTitle(titleId)
                .setIcon(android.R.drawable.stat_sys_warning)
                .setMessage(messageId)
                .setCancelable(false)
                .setPositiveButton(android.R.string.ok, null)
                .setNegativeButton("Learn More", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        Intent intent = new Intent(Intent.ACTION_VIEW, helpUri);
                        startActivity(intent);
                    }
                });
        }
        return builder.create();

    }


    @Override
    public void onRestart(){
        super.onRestart();
        Intent previewMessage = new Intent(StampiiStore.this, StampiiStore.class);
        TabGroupActivity parentActivity = (TabGroupActivity)getParent();
        parentActivity.startChildActivity("StampiiStore", previewMessage);
        this.finish();
    }

}

下面是我在 list 文件中声明服务的方式:

<service android:name="BillingService" />

    <receiver android:name="BillingReceiver">
        <intent-filter>
            <action android:name="com.android.vending.billing.IN_APP_NOTIFY" />
            <action android:name="com.android.vending.billing.RESPONSE_CODE" />
            <action android:name="com.android.vending.billing.PURCHASE_STATE_CHANGED" />
        </intent-filter>
    </receiver>

有什么关于如何连接市场的建议吗？

我遇到了同样的问题，可能你的错误和我的一样。我在我的 Activity 中使用了 TabHost，我发现 TabSpec 无法绑定(bind)到服务。所以检查这个:

Using getApplicationContext().bindService instead of just bindService on your activity solves the problem as it is using the higher level application context.
