sd card video content display (album wise) ( android)

hi guys i am making an android application IN which i have to display all the video contents of the sd card (album wise).....it means when WE WILL LOAD THE APPLICATION only the names of albums should be displayED.... AND when we click on the particular album ITS VIDEOS FILES SHOULD BE DISPLAYED................... i have been able to display the album names BUT THE PROBLEM IS THAT there is duplicate album names (i.e. IF TWO VIDEO files are of same album) then two different albums are being displaying...........so i want all the videos of same album should be in one "album name"........... and on the click of that album name "all its video contents should be displayed"
any help will be appreciated below is the main class (AlbumVideo.class)
public class AlbumVideo extends Activity {

wow after so much time spent on the internet at last found the solution for it !!!!!!! it an easy n very short step .,][.....i hope it will be helpful to someone ..........
private void init_phone_videos_grid() {
System.gc();
String[] proj = { MediaStore.Video.Media.DATA,
MediaStore.Video.Media._ID, MediaStore.Video.Media.TITLE,
MediaStore.Video.Media.DISPLAY_NAME,
MediaStore.Video.Media.MIME_TYPE,
MediaStore.Video.Media.DURATION,
MediaStore.Video.Media.SIZE,};
String where = android.provider.MediaStore.Video.Media.ALBUM + "=?";
String whereVal[] = { filename };
String orderBy = android.provider.MediaStore.Video.Media.TITLE;
videocursor = managedQuery(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, "DISTINCT "
+proj, where, whereVal, orderBy);
count = videocursor.getCount();
videolist = (ListView) findViewById(R.id.PhoneVideoList);
videolist.setAdapter(new VideoAdapter(getApplicationContext()));
}
just to add the word "distinct" in the class "album detail"....n it will sort d query according to yourt requirement....

Change the following:
final String[] projection = new String[] {MediaStore.Video.VideoColumns.ALBUM };
into
final String[] projection = new String[]{ "DISTINCT " +MediaStore.Video.VideoColumns.ALBUM};

Get Images and Videos from Android Phone into Custom Gallery

I'm trying to create a custom gallery that allows users to pick from all the photos and videos contained on their Android device. I know how to create a gallery of just photos and just videos, but if I want to combine both, how can I do this?
I think the issue comes down to how I create my cursor. To select all videos, I created the cursor this way:
String[] videoParams = {MediaStore.Video.Media._ID,
MediaStore.Video.Media.DATA,
MediaStore.Video.Media.DATE_TAKEN,
MediaStore.Video.Thumbnails.DATA};
videocursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, videoParams, null, null, null);
If I want to query all the media files, not just video, what do I do?
This is what I tried, based off of: Custom Gallery with Images and Videos in android to select multiple items
String selectionMimeType = MediaStore.Files.FileColumns.MIME_TYPE + "=?";
String jpg_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("jpg");
String png_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("png");
String mp4_mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("mp4");
String[] selectionArgs = new String[]{jpg_mimeType, png_mimeType, mp4_mimeType};
mediaCursor = getContentResolver().query(MediaStore.Files.getContentUri("internal"), null, selectionMimeType, selectionArgs, MediaStore.Files.FileColumns.DATE_ADDED);
This gives me the error java.lang.IllegalArgumentException: Cannot bind argument at index 3 because the index is out of range. The statement has 1 parameters at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:167)
Perhaps my approach is completely wrong, but I can't find any examples of custom android galleries using both images and videos, which is bizarre to me as this seems like it would be a common thing to create.
Here's all of my code, in case it's helpful:
public class GridViewCompatActivity extends Activity {
GridViewCompat gridView;
private static final String TAG = "GridViewCompatActivity";
Cursor videocursor;

#Override

// NOTE: We are using setChoiceMode, as I said, its a drop-in replacement
gridView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
gridView.setAdapter(new ImageAdapter(getApplicationContext()));

#Override

File[] files;
files = parentDir.listFiles();
if (files != null) {

return inFiles;
}
Use :
private static final String WHATSAPP_STATUSES_LOCATION =
"/storage/emulated/0/yourfoldername";
getListFiles(new File(WHATSAPP_STATUSES_LOCATION));

use this code`
String path = Environment.getExternalStorageDirectory().toString()+"/Your Folder/";`
File f = new File(path);
File file[] = f.listFiles();
for (int i=0; i < file.length; i++)
{
Log.d("Files", "FileName:" + file[i].getName());
}
above code give you all file from the folder ,after you can separate
using it's extension

How to get the images from sdcard and display it in gridview

Actually I tried with this coding it's working fine.i.e., showing all the images perfectly in emulator but coming to mobile it showing repeatedly the same image. I have attached the adapter class also
File file[] = Environment.getExternalStorageDirectory().listFiles();
String strFile = "";
for (int i = 0; i < file.length; i++) {
strFile += file[i].getAbsolutePath() + " :: ";
System.out.println("\n");
}
Log.i("test", strFile);
String[] img = { MediaStore.Images.Thumbnails._ID };
imagecursor = managedQuery(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, null,
null, MediaStore.Images.Thumbnails.IMAGE_ID + "");
image_column_index = imagecursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
count = imagecursor.getCount();
imagegrid = (ListView) findViewById(R.id.PhoneImageGrid);
imagegrid.setAdapter(new ImageAdapter(getApplicationContext()));
imagegrid.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position,
long id) {
System.gc();
String[] proj = { MediaStore.Images.Media.DATA };
actualimagecursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,
null, null, null);
actual_image_column_index = actualimagecursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
actualimagecursor.moveToPosition(position);
String i = actualimagecursor
.getString(actual_image_column_index);
System.gc();
Intent intent = new Intent(getApplicationContext(),
ViewImage.class);
intent.putExtra("filename", i);
startActivity(intent);
}
});
}
Adapter Class:
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return count;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
System.gc();
ImageView i = new ImageView(mContext.getApplicationContext());
if (convertView == null) {
imagecursor.moveToPosition(position);
int id = imagecursor.getInt(image_column_index);
i.setImageURI(Uri.withAppendedPath(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""
+ id));
i.setScaleType(ImageView.ScaleType.CENTER_CROP);
i.setLayoutParams(new GridView.LayoutParams(92, 92));
} else {
i = (ImageView) convertView;

mediaplayer: album and display songs in it

When we click on albums than it should display list of songs in album, I try like this but it displays all the songs in SD card.
private OnItemClickListener musicgridlistener1 = new OnItemClickListener(){
public void onItemClick(AdapterView parent, View v, int position,long id)
{
System.gc();
album_column_index1 = musiccursor
.getColumnIndexOrThrow(MediaStore.Audio.AlbumColumns.ALBUM_ART);
musiccursor.moveToPosition(position);
MUSICfilename = musiccursor.getString(album_column_index1);
Log.i("=======this is file name of album========",""+musiccursor.getCount()+" "+MUSICfilename+" "+position);
String[] ablummusicproj = {MediaStore.Audio.Media.DATA,
MediaStore.Audio.AlbumColumns.ALBUM,
MediaStore.Audio.AlbumColumns.ARTIST,
MediaStore.Audio.Media.DISPLAY_NAME};
final String sortOrder = MediaStore.Audio.Media.ALBUM_KEY + " COLLATE LOCALIZED ASC";
//final String sortOrder= MediaStore.Audio.Media.ALBUM_KEY + " ASC, "
// + MediaStore.Audio.Media.TRACK + " ASC, "
// + MediaStore.Audio.Media.TITLE_KEY + " ASC";
Uri uri = android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
musicAlbum = getBaseContext().getContentResolver().query(uri, ablummusicproj, null, null, sortOrder);
count = musicAlbum.getCount();
Log.i("++++++++++ value of album cursor is ",""+count);
gridmusic = (GridView) findViewById(R.id.gridmusic);

gridmusic.setAdapter(madAdapter_internal);
gridmusic.setOnItemClickListener(musicgridlistener);
musiccursor=musicAlbum;
}
};

if (convertView == null) {
music_column_index = musicAlbum.getColumnIndexOrThrow(MediaStore.Audio.AudioColumns.DISPLAY_NAME);
musicAlbum.moveToPosition(position);
id = musicAlbum.getString(music_column_index);
//music_column_index = musiccursor
//.getColumnIndexOrThrow(MediaStore.Audio.Media.SIZE);

you would have to store the album_key when u get the albums.
mediaStoreURI = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.ALBUM_KEY + "=?";
String[] projection = new String[] { MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media.ALBUM, MediaStore.Audio.Media.ALBUM_ID, MediaStore.Audio.Media.ARTIST,
"strftime(\"%H-%M-%S\", (" + MediaStore.Audio.Media.DURATION + "/1000), \"unixepoch\") as time" };
String[] selectionArgs = new String[] { ((MediaContainerUSB) currentMediaObject).getUSBGroupingKey() };
String sortOrder = MediaStore.Audio.Media.TRACK;
the album_key is generated for ever album in the sdcard and stored in a different table as well.
