出现错误“The application ...has stopped unexpectedly.”

Question

小弟在调试芒果广告时出现错误“The application ...has stopped unexpectedly.”，代码如下：
--------------------------------------------------------------------------------------
package mogot2.x;import com.admogo.AdMogoLayout;
import com.admogo.AdMogoListener;
import com.admogo.AdMogoManager;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;
import android.widget.FrameLayout;public class Mogot2Activity extends Activity implements AdMogoListener {

private final String mogoID = "399b65e0b89346c9b59f7ed90fbd5949"; @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/************************ 代码方式添加Banner广告 ***********************/
AdMogoLayout adMogoLayoutCode = new AdMogoLayout(this, mogoID);
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.FILL_PARENT,
FrameLayout.LayoutParams.WRAP_CONTENT);
// 设置广告出现的位置(悬浮于底部)
params.bottomMargin = 0;
// 添加广告状态监听

params.gravity = Gravity.BOTTOM;
addContentView(adMogoLayoutCode, params);
/*************************** 添加Banner广告结束 ************************/
} @Override
public void onClickAd() {
Log.v("=onClickAd=", "Click the buttom ad.");
} @Override
public void onFailedReceiveAd() {
Log.v("=onFailedReceiveAd=", "Failed to receive the buttom ad.");
} @Override
public void onReceiveAd() {
Log.v("=onReceiveAd=", "Receive the buttom ad.");
} @Override
protected void onDestroy() {
AdMogoManager.clear();
super.onDestroy();
}}
-------------------------------------------------------------------------------------
备注：同样的代码在芒果给出的例子上调试没有任何错误，但自己另外创建一个应用，然后将以上代码复制上去，就会出现错误“The application ...has stopped unexpectedly.”
