我正在努力让AdWhirl库工作。日志显示各种异常，但即使这样，应用程序实际上也可以。它只是没有显示任何广告。这是我现在正在使用的代码：
private void adStuff() {
LinearLayout mAdLayout = (LinearLayout) findViewById(R.id.AdLayout);
AdWhirlManager.setConfigExpireTimeout(1000 * 60 * 5);
RelativeLayout.LayoutParams adWhirlLayoutParams = new RelativeLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
int mAdWidth = 320;
int mAdHeight = 75;
AdWhirlTargeting.setAge(23);
AdWhirlTargeting.setGender(AdWhirlTargeting.Gender.MALE);
AdWhirlTargeting.setKeywords("android");
AdWhirlTargeting.setPostalCode("47007");
AdWhirlTargeting.setTestMode(false);
DisplayMetrics mDisplayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(mDisplayMetrics);
mAdHeight = mDisplayMetrics.heightPixels;
float mDensity = mDisplayMetrics.density;
mAdWidth = mDisplayMetrics.widthPixels;
mAdHeight = (int) (mAdHeight * mDensity);
AdWhirlLayout adWhirlLayout = new AdWhirlLayout(this,
getResources().getString(R.string.adwhirlid));
adWhirlLayout.setAdWhirlInterface(this);
adWhirlLayout.setMaxWidth(mAdWidth);
adWhirlLayout.setMaxHeight(mAdHeight);
adWhirlLayoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
mAdLayout.setGravity(Gravity.CENTER_HORIZONTAL);
mAdLayout.addView(adWhirlLayout, adWhirlLayoutParams);
mAdLayout.invalidate();
}
我在onCreate（）的末尾调用此方法。
这是我的主要布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingLeft="8dp"
android:paddingRight="8dp" >
<EditText
android:id="@+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="number" >
<requestFocus />
</EditText>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="@+id/buttonSearch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/buscar"
android:background="@drawable/auvasa_button"/>
<Button
android:id="@+id/buttonList"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/listaparadas"
android:background="@drawable/auvasa_button"/>
</LinearLayout>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/AdLayout">
这是我得到的一堆例外的日志：

有谁能告诉我我做错了什么？我修改了代码几十次，我无法让它工作。我知道服务器返回一个null json，我真的不知道为什么。
