[Android] MediaStore

The Media provider contains meta data for all available media on both internal and external storage devices.

A Example:

String[] projection = new String[] {
  Images.ImageColumns._ID,
  Images.ImageColumns.BUCKET_DISPLAY_NAME,
  Images.ImageColumns.BUCKET_ID,
  Images.ImageColumns.DATE_TAKEN,
  Images.ImageColumns.DESCRIPTION,
  Images.ImageColumns.IS_PRIVATE,
  Images.ImageColumns.LATITUDE,
  Images.ImageColumns.LONGITUDE,
  Images.ImageColumns.MINI_THUMB_MAGIC,
  Images.ImageColumns.ORIENTATION,
  Images.ImageColumns.PICASA_ID,
  Images.ImageColumns.DATA,
  Images.ImageColumns.DATE_ADDED,
  Images.ImageColumns.DATE_MODIFIED,
  Images.ImageColumns.DISPLAY_NAME,
  Images.ImageColumns.MIME_TYPE,
  Images.ImageColumns.SIZE,
  Images.ImageColumns.TITLE
};

// We can use the following query method to query data.
//Cursor cursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, null, null);

Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, null, null);

int count = cursor.getCount();

System.out.println("count = " + count);

for (int i=0; i<count; i++)
{
  cursor.moveToPosition(i);
  int columnSize = cursor.getColumnCount();
  for (int j=0; j<columnsize; j++)
  {
    System.out.println("index = " + j + " " + cursor.getColumnName(j) + " = " + cursor.getString(j));
  }
}
