cromeブラウザからブックマークページを取得してアンドロイドアプリに表示する方法は？

Question

final String[] columns = { Browser.BookmarkColumns.TITLE, Browser.BookmarkColumns.URL }; 
Cursor query = getContentResolver().query(Browser.BOOKMARKS_URI,columns, null, null, null); 
query.moveToFirst(); 
while (query.moveToNext()) { 
String title = query.getString(query.getColumnIndex(Browser.BookmarkColumns.TITLE)); 
String url = query.getString(query.getColumnIndex(Browser.BookmarkColumns.URL)); 
Log.d("msg"," d "+title+" d "+url); 
urlArray.add(url); 
} 

私はこのコードを使用していますが、このコードは私にブラウザの履歴を与えます。ブックマークのページURLだけを取得したいと思います。

このコードを試してみて、

MainActivity.java：

public class MainActivity extends Activity { 

private ArrayList<String> titles; 
private ArrayList<String> urls; 
private ArrayList<Bitmap> bitmaps; 
private ContentResolver cr; 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    createLists(); 
} 
protected void onResume(){ 
    super.onResume(); 
    getBH(); 
    showHistoryBookmarks(); 

} 

public void createLists(){ 
    titles=new ArrayList<String>(); 
    urls=new ArrayList<String>(); 
    bitmaps=new ArrayList<Bitmap>(); 

} 
public void getBH(){ 
    Bitmap icon; 
    cr=getContentResolver(); 
    String order= Browser.BookmarkColumns.DATE+" DESC"; 
    String[] projection={Browser.BookmarkColumns.TITLE,Browser.BookmarkColumns.URL,Browser.BookmarkColumns.FAVICON}; 
    //String selection=projection[0]+"=?"; 
    //String args[]={"Google"}; 
    Cursor rows=cr.query(Browser.BOOKMARKS_URI,projection, null,null,order); 
    if(rows.getCount()>0){ 
     while(rows.moveToNext()) { 
      //read title 
      String title=rows.getString(rows.getColumnIndex(projection[0])); 
      //read url 
      String url=rows.getString(rows.getColumnIndex(projection[1])); 
      //read icon 
      byte[] bicon=rows.getBlob(rows.getColumnIndex(projection[2])); 
      if(bicon!=null){ 
       //convert blob image data to Bitmap 
       icon=BitmapFactory.decodeByteArray(bicon,0,bicon.length); 

      } 
      else{ 
       //default icon for history and bookmarks that do not icons 
       icon=BitmapFactory.decodeResource(getResources(),R.drawable.star2); 
      } 
      //add to lists 
      addToList(title,url,icon); 
     } 
     //close the cursor 
     rows.close(); 
    } 
} 

public void getBrowserHist() { 
    Cursor mCur = managedQuery(Browser.BOOKMARKS_URI, 
      Browser.HISTORY_PROJECTION, null, null, null); 
    mCur.moveToFirst(); 
    if (mCur.moveToFirst() && mCur.getCount() > 0) { 
     while (mCur.isAfterLast() == false) { 
      Log.v("titleIdx", mCur 
        .getString(Browser.HISTORY_PROJECTION_TITLE_INDEX)); 
      Log.v("urlIdx", mCur 
        .getString(Browser.HISTORY_PROJECTION_URL_INDEX)); 
      mCur.moveToNext(); 
     } 
    } 
} 


public void addToList(String title,String url, Bitmap bitmap){ 

    titles.add(title); 
    urls.add(url); 
    bitmaps.add(bitmap); 

} 


public void showHistoryBookmarks(){ 
    ListView l=(ListView) findViewById(R.id.hb_list); 
    if(l!=null){ 
     if(titles.size()>0){ 
      ListAdapterModel aa=new ListAdapterModel(this,R.layout.listlayout,R.id.hbtitle,titles,urls,bitmaps); 
      l.setAdapter(aa); 
     } 
     else{ 
      Toast.makeText(this, "This is no bookmark or history.", Toast.LENGTH_SHORT).show(); 
     } 
    } 

} 

public void cleanHB(){ 
    if(Browser.canClearHistory(cr)){ 
     Browser.clearHistory(cr); //clear history data 
     createLists(); //recreate the lists 
     onResume(); //update the list 
    } 

} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    //Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

public boolean onOptionsItemSelected(MenuItem item){ 
    if(item.getItemId()==R.id.action_clean) 
    { 
     cleanHB(); 

    } 
    return false; 
} 

}
