无法在 Android 应用程序中显示 Mopub 的原生广告

Question

我已与 Mopub 集成，用于在我的 Android 应用程序中显示广告。 我可以展示横幅广告和插页式广告，但不能展示原生广告，

布局文件代码，

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical"  >
  <TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/note_title_label"
    style="?android:listSeparatorTextViewStyle"
    />
  <EditText android:id="@+id/note_title"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/note_title_hint"
    />
    <TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/note_details_label"
    style="?android:listSeparatorTextViewStyle"
    />
    <EditText android:id="@+id/note_details"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/note_details_hint"
    />
    <Button android:id="@+id/note_date"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    />
    <CheckBox android:id="@+id/note_solved"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    android:text="@string/note_solved_label"
    />

    <RelativeLayout  android:id="@+id/native_ad_layout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="50dp">
    >    
    <ImageView android:id="@+id/native_ad_main_image"
                    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
        />  
    <ImageView android:id="@+id/native_ad_icon_image"
                    android:layout_width="fill_parent"
    android:layout_height="wrap_content"  
         />  
    <TextView android:id="@+id/native_ad_title" 
            android:layout_width="fill_parent"
    android:layout_height="wrap_content"
        />  
    <TextView android:id="@+id/native_ad_text" 
       android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        />
</RelativeLayout>

</LinearLayout>

fragment.java（与上述布局关联）文件中用于显示原生广告的逻辑，

    @TargetApi(11)
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent,
    Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_note, parent, false);



    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        if (NavUtils.getParentActivityName(getActivity()) != null) {
        getActivity().getActionBar().setDisplayHomeAsUpEnabled(true);
        }
    }
    mTitleField = (EditText)v.findViewById(R.id.note_title);
    mTitleField.setText(mNote.getTitle());
    mTitleField.addTextChangedListener(new TextWatcher() {
    public void onTextChanged(CharSequence c, int start, int before, int count) 
    { 

    String title=Character.toUpperCase(c.toString().charAt(0)) + c.toString().substring(1);
    mNote.setTitle(title);
    }
    public void beforeTextChanged(
    CharSequence c, int start, int count, int after) 
    {// This space intentionally left blank
    }
    public void afterTextChanged(Editable c) {
    // This one too
    }
    });
    mDetailsField = (EditText)v.findViewById(R.id.note_details);
    mDetailsField.setText(mNote.getDetails());
    mDetailsField.addTextChangedListener(new TextWatcher() {
    public void onTextChanged(
    CharSequence c, int start, int before, int count) 
    { 
    mNote.setDetails(c.toString());
    }
    public void beforeTextChanged(
    CharSequence c, int start, int count, int after) 
    {// This space intentionally left blank
    }
    public void afterTextChanged(Editable c) {
    // This one too
    }
    });


    mDateButton = (Button)v.findViewById(R.id.note_date);
    mDateButton.setText(mNote.getDate().toString());
    //mDateButton.setEnabled(false);
    mDateButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
        FragmentManager fm = getActivity()
        .getSupportFragmentManager();
        //DatePickerFragment dialog = new DatePickerFragment();
        DatePickerFragment dialog = DatePickerFragment
                .newInstance(mNote.getDate());
        dialog.setTargetFragment(NoteFragment.this, REQUEST_DATE);
        dialog.show(fm, DIALOG_DATE);
        }
        });

    mSolvedCheckBox = (CheckBox)v.findViewById(R.id.note_solved);
    mSolvedCheckBox.setChecked(mNote.isSolved());
    mSolvedCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // set the note's solved property
            mNote.setSolved(isChecked);
        }
    });  
/*    Button reportButton = (Button)v.findViewById(R.id.note_reportButton);
    reportButton.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("vnd.android-dir/mms-sms");
    i.putExtra(Intent.EXTRA_TEXT, getNoteReport());
    i.putExtra(Intent.EXTRA_SUBJECT,
            mNote.getTitle());

    Intent sendIntent = new Intent(Intent.ACTION_VIEW);         
    sendIntent.setData(Uri.parse("sms:"));
    sendIntent.putExtra("sms_body", "test man text");
    startActivity(sendIntent);
    }
    });*/

    //advertising start
    MoPubNative.MoPubNativeListener moPubNativeListener = new MoPubNative.MoPubNativeListener() {

    ViewBinder viewBinder = new ViewBinder.Builder(R.layout.list_item_note)

所以请有人告诉我代码有什么问题，或者如果有人有关于如何将 mopub 原生广告集成到 android 应用程序的示例代码，请分享....

这里是我用来展示原生广告的代码

  public class NativeAdActivity extends Activity {

    private MoPubAdAdapter mAdAdapter;
    private static final String MY_AD_UNIT_ID_PHONE = "xxxxxx";
    private static final String MY_AD_UNIT_ID_TAB = "xxxxxx";
    String screenSize;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.native_ad_display);

        // Set location awareness and precision globally 
        MoPub.setLocationAwareness(MoPub.LocationAwareness.TRUNCATED);
        MoPub.setLocationPrecision(4);

        // variable to grab the screenSize form resources 
        screenSize = getResources().getString(R.string.screen_type);


        final ListView listView = (ListView) findViewById(R.id.native_list_view);


        final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1);
        for (int i = 0; i < 100; ++i) {
            adapter.add("Item " + i);
        }

        // Create an ad adapter with ads in positions 0, 4, and every 10 places thereafter.
        // This adapter will be used in place of the original adapter for the ListView.
        mAdAdapter = new MoPubAdAdapter(this, adapter, MoPubNativeAdPositioning.clientPositioning()
                .addFixedPosition(0)
                .addFixedPosition(4)
                .enableRepeatingPositions(10));

        // Set up an renderer that knows how to put ad data in an ad view.
        final MoPubNativeAdRenderer adRenderer = new MoPubNativeAdRenderer(
                new ViewBinder.Builder(R.layout.native_ad_layout)
                .titleId(R.id.native_ad_title)
                .textId(R.id.native_ad_text)
                .mainImageId(R.id.native_ad_main_image)
                .iconImageId(R.id.native_ad_icon_image)
                .build());

        // Register the renderer with the MoPubAdAdapter and then set the adapter on the ListView.
        mAdAdapter.registerAdRenderer(adRenderer);
        listView.setAdapter(mAdAdapter);

    }
    @Override
    public void onResume() {
        // MoPub recommends loading knew ads when the user returns to your activity.
        if(screenSize.equalsIgnoreCase("phone"))
        {
            mAdAdapter.loadAds(MY_AD_UNIT_ID_PHONE);
        }else if(screenSize.equalsIgnoreCase("7-inch-tablet"))
        {
            mAdAdapter.loadAds(MY_AD_UNIT_ID_TAB);

        }else if(screenSize.equalsIgnoreCase("10-inch-tablet") )
        {   
            mAdAdapter.loadAds(MY_AD_UNIT_ID_TAB);
        }
        else //deafault case for phone
        {
            mAdAdapter.loadAds(MY_AD_UNIT_ID_PHONE);
        }
        super.onResume();
    }
