Pick a file using Intent.ACTION_GET_CONTENT

If you have to pick a file in your app, but you don't want to implement your own file explorer; you can start a activity with intent of Intent.ACTION_GET_CONTENT. Android OS will choice a suitable app with such function for you.

Pick a file using Intent.ACTION_GET_CONTENT

package com.exercise.AndroidPick_a_File;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class AndroidPick_a_File extends Activity {
 
 TextView textFile;
 
 private static final int PICKFILE_RESULT_CODE = 1;
 
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
      
       Button buttonPick = (Button)findViewById(R.id.buttonpick);
       textFile = (TextView)findViewById(R.id.textfile);
      
       buttonPick.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub

    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
             intent.setType("file/*");
       startActivityForResult(intent,PICKFILE_RESULT_CODE);
    
   }});
   }

 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  // TODO Auto-generated method stub
  switch(requestCode){
  case PICKFILE_RESULT_CODE:
   if(resultCode==RESULT_OK){
    String FilePath = data.getData().getPath();
    textFile.setText(FilePath);
   }
   break;
   
  }
 }
}

Good tutorial.. But gives error if there is no External File Explorer Installed:

hello Anuj Devasthali,

yes, this example assume user have install file explorer apps to handle intent of ACTION_GET_CONTENT. But it's not include in default Android system.

Or you have to implement your own File Explorer. It's a very simple example, may be you have to do much more to make it as a completed app.

To pick a directory, refer to Example of using Intent.ACTION_OPEN_DOCUMENT_TREE, to pick a directory subtree.. But it work on API Level 21 upper!
