How to get the complete path of file from android application

[Mohit G Gupta]

i have multiple text files in my sdcard folder and i have build an activity that allows user to select the required file.



but stil,i have to use pass the filepath to file constructor(see line2).
textfile.java:

    File sdcard = Environment.getExternalStorageDirectory();
                
            //Get the text file
             
            File file = new File(sdcard,"my/ans.txt");//line2
             
            //ob.pathh
             //Read text from file
            
             StringBuilder text = new StringBuilder();
             try {
                 BufferedReader br = new BufferedReader(new FileReader(file));
               
             } 

i want the second parameter ie filepath to be stored as string.
is there any way i can get the complete path of file selected .
The code i had used is as follows:

AndroindApplication .java:

    import java.io.File;
    import java.util.ArrayList;
    import java.util.List;
    import android.app.AlertDialog;
    import android.app.ListActivity;
    import android.content.DialogInterface;
    import android.content.Intent;
    import android.os.Bundle;
    import android.util.Log;
    import android.view.View;
    import android.widget.ArrayAdapter;
    import android.widget.ListView;
    import android.widget.TextView;
    
    public class AndroindApplication extends ListActivity {
    	
     private List<String> item = null;
     public List<String> path = null;
     private String root="/";
     private TextView myPath;
     public String pathh;
     
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.sdcard);
            myPath = (TextView)findViewById(R.id.path);
            getDir("/sdcard/");
        }
        
        private void getDir(String dirPath)
        {
         myPath.setText("Location: " + dirPath);
         
         item = new ArrayList<String>();
        
         path = new ArrayList<String>();
         
         File f = new File(dirPath);
         File[] files = f.listFiles();
         
         
         if(!dirPath.equals(root))
         {
        
          item.add(root);
          path.add(root);
          
          item.add("../");
          path.add(f.getParent());
                
         }
         
         for(int i=0; i < files.length; i++)
         {
           File file = files[i];
           path.add(file.getPath());
           if(file.isDirectory())
            item.add(file.getName() + "/");
           else
            item.add(file.getName());
         }
    
         ArrayAdapter<String> fileList =
          new ArrayAdapter<String>(this, R.layout.row, item);
         setListAdapter(fileList);
        }
    
     @Override
     protected void onListItemClick(ListView l, View view, int position, long id) {
      
      File file = new File(path.get(position));
      pathh=path.get(position);
      Log.e("path="+path,"dxgx");
      if (file.isDirectory())
      {
       if(file.canRead())
        getDir(path.get(position));
       else
       {
    	   
        new AlertDialog.Builder(this)
        .setIcon(R.drawable.icon)
        .setTitle("[" + file.getName() + "] folder can't be read!")
        .setPositiveButton("OK", 
          new DialogInterface.OnClickListener() {
           
           public void onClick(DialogInterface dialog, int which) {
            // TODO Auto-generated method stub
           }
          }).show();
       }
      }
      else
      {
    	  Intent  myIntent = new Intent(view.getContext(), textfile.class);//goes to textfile.java
    	  startActivityForResult(myIntent, 0);
    	 
    	  
      }
     }
    }

Does this help: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal

[Mohit G Gupta]

i need to get the absolute path so that i can pass it to

File file = new File(sdcard,"my/ans.txt");//line2

and don't have to specify the filepath in the code whenver a new file has to be opened

Is there anyway i can get it from AndroidApplication.java ?

THe link you gave was not much useful

I'm sorry, but I have no idea what it is that you want to do. You want the "absolute path" of what? The line of code you posted doesn't give me any clues either. Is it that you want to know what to set "sdcard" to?

Or are you saying you and the absolute path to ans.txt? If so, how is any code supposed to know that automatically since that file is one that you designate?

Perhaps if you posted the code you would like to write, rather than existing code...
