FileNotFoundException in android file picker

Question

I want to upload the file from mobile storage(both internal and external storage) to the server.By using a file chooser I got FileNotFoundException. Here is the snippet of my code:

public void openFileSystem(){
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("*/*");
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    startActivityForResult(Intent.createChooser(intent, "Select file to upload."), SELECT_FILE);
}

Here is my onActivityResult() and getPath():

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == SELECT_FILE && resultCode == Activity.RESULT_OK) {

        Uri path = data.getData();
        String url = data.getData().getPath();
        File file = new File(url);
        int size = (int) file.length();
        byte[] bytes = new byte[size];
        try {
            BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
            buf.read(bytes, 0, bytes.length);
            buf.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

 public String getPath(Uri uri) {
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(uri, projection, null, null, null);
        if(cursor!=null)
        {
            int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index);
        }
        else return null;
    }

The error log:

So my motto is to choose any file(image, pdf ,doc) from internal storage or external storage and upload it on the server. Any help will be appreciated!

Try this...

 Browse = (ImageView)findViewById(R.id.browsehoro);
    Browse.setOnClickListener(this); 

 public void onClick(View v)
{

    switch(v.getId())
    {

    case R.id.browsehoro:
        img.setEnabled(true);
        Intent intent = new Intent(Horoscope.this, FilePickerHoroscope.class);            
        startActivityForResult(intent, REQUEST_PICK_FILE);
        break;
    }


}

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{

    if (resultCode == RESULT_OK) {
       /* if (requestCode == REQUEST_PICK_FILE) {
            Uri selectedImageUri = data.getData();
            selectedFile = getPath(selectedImageUri);

 //                Print imagepath in textview here
            filePath.setText(selectedFile);
            System.out.println(requestCode);
            System.out.println("Image Path : " + selectedFile);
            img.setImageURI(selectedImageUri);


        }*/


        switch(requestCode) 
        {

        case REQUEST_PICK_FILE:

            if(data.hasExtra(FilePickerHoroscope.EXTRA_FILE_PATH))
             {
                selectedFile = new String
                        (data.getStringExtra(FilePickerHoroscope.EXTRA_FILE_PATH));
                filePath.setText(selectedFile.toString());  
            }
            break;
        }
    }
}

Answer 2

That is not reliable with ACTION_GET_CONTENT, as there is no requirement that the Uri get back point to a file that you can access. The file might be on internal storage of an app, or on removable media, or even in the cloud somewhere. For what feels like the sixth time this week and definitely the second within the past ten minutes... a Uri is not a file.

Use the Uri as designed, via methods on ContentResolver like openInputStream() and getType().

Answer 3

String url = data.getData().getPath();
File file = new File(url);

The String url does contain a content provider path. In this case as you can see in the logcat /document/2. The File class cannot handle such content provider paths.

You first have to convert that path to a real file system path.

Google for 'getRealPathFromUri'.
