Get File from Google drive using Intent

Question

I am trying to upload document from my app.

Everything working fine but when i choose file from drive.

data=Intent { act=android.intent.action.VIEW dat=content://com.google.android.apps.docs.storage.legacy/enc=ckpgt5KcEEF_JYniJQafRV_5pEnu_D5UAI1WF-Lu6h2Z_Vw4
     (has extras) }}

Can any body know how to handle this file.

I had already handle all files and images only facing problem with google drive files.

I am getting this content://com.google.android.apps.docs.storage.legacy/enc=ckpgt5KcEEF_JYniJQafRV_5pEnu_D5UAI1WF-Lu6h2Z_Vw4 in intent data Uri.

Answer 1

Handle Uri received by Google-Drive files when selected through file chooser.

as stated earlier it receives Virtual File Uri.

I found this sample code simple and easy to understand. the given code sample worked for me .hope it works in your case.

1.So detect this Uri is received by google drive.

public static File getFileFromUri(final Context context, final Uri uri) throws Exception {

if (isGoogleDrive(uri)) // check if file selected from google drive
{ 
  return saveFileIntoExternalStorageByUri(context, uri);
}else 
    // do your other calculation for the other files and return that file
   return null;
}


public static boolean isGoogleDrive(Uri uri)
{
 return "com.google.android.apps.docs.storage.legacy".equals(uri.getAuthority());
}

2.if yes,the uri is stored to external path(here its root directory u can change it according to your need) and the file with that uri is created.

 public static File saveFileIntoExternalStorageByUri(Context context, Uri uri) throws 

Exception {
        InputStream inputStream = context.getContentResolver().openInputStream(uri);
        int originalSize = inputStream.available();

        BufferedInputStream bis = null;
        BufferedOutputStream bos = null;
        String fileName = getFileName(context, uri);
        File file = makeEmptyFileIntoExternalStorageWithTitle(fileName);
        bis = new BufferedInputStream(inputStream);
        bos = new BufferedOutputStream(new FileOutputStream(
                file, false));

        byte[] buf = new byte[originalSize];
        bis.read(buf);
        do {
            bos.write(buf);
        } while (bis.read(buf) != -1);

        bos.flush();
        bos.close();
        bis.close();

        return file;

    }

public static String getFileName(Context context, Uri uri) 
{
  String result = null;
  if (uri.getScheme().equals("content")) {
  Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
  try {
       if (cursor != null && cursor.moveToFirst()) {
        result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
       }
      } finally {
                cursor.close();
            }
        }
        if (result == null) {
            result = uri.getPath();
            int cut = result.lastIndexOf('/');
            if (cut != -1) {
                result = result.substring(cut + 1);
            }
        }
        return result;
}


public static File makeEmptyFileIntoExternalStorageWithTitle(String title) {
        String root =  Environment.getExternalStorageDirectory().getAbsolutePath();
        return new File(root, title);
    }

Note:Here the virtual file is retrieved from Intent getData() and used in context.getContentResolver().openInputStream(intent.getData()), this will return an InputStream. It's handle to get selected file from google drive.
