How to open default gallery app with particular album or folder?

Every example i found on net is opening gallery and get images from gallery as result. My need is i don't want result or images to my app. I just want to trigger gallery app with showing particular folder of images. My App Have separate folder to save images. i need to navigate users directly to that path.

Try this code. It will retrieve view pictures under storage/emulated/0/Pictures/AppPics You can change the file path according to your directory path.
File sdDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File file = new File(sdDir, "AppPics");
if (file.isDirectory())
listFile = file.listFiles();
EDIT: To open your folder using intent
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.withAppendedPath(Uri.fromFile(file), "/AppPics"), "image/*");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

You can try like this,
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = [Uri for your folder];
intent.setDataAndType(uri, "image/*");
startActivity(Intent.createChooser(intent, "Open [App] images"));

How to open the My Files folder in Android Programatically (using Intent)?

I am using the below code which opens up the Gallery, Music Player, Dropbox and Contacts, i want the My Files folder to get open programatically, please let me know if there are any specific intent parameters i need to pass to get the File Manager open.
if it is not possible through intent then please give me a snippet or an hint to open the My Files folder programatically.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
Intent i = Intent.createChooser(intent, "View Default File Manager");
startActivityForResult(i, CHOOSE_FILE_REQUESTCODE);
Thanks.

You can use this code to file the files.
int PICKFILE_RESULT_CODE=1;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent,PICKFILE_RESULT_CODE);
this will help you to browse the files from your storage.

Its best that you include a library in your project which handles this scenario.
This worked for me:
This library shows the list of third-party apps. It also has its own file browser for selecting files.

Bad thing is, most Android distributions may or may not ship with a file manager, and even so, may be not with the one which handles CHOOSE_FILE_REQUESTCODE.
So, you are left to create your own file picker activity. Luckily there are many ready made ones available:
http://code.google.com/p/android-filechooser/
https://developers.inkfilepicker.com/docs/android/

If you want to open samsung My Files application try this below code.
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);

You have to specifically mention the package name of the explorer application. Please find the example below to open a specific folder in ES Explorer.
public void openfolderInexplorer(String path){
Intent intent = this.getPackageManager().getLaunchIntentForPackage("com.estrongs.android.pop");
if (intent != null) {
// If the application is avilable
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Uri uri = Uri.parse(path);
intent.setDataAndType(uri, "resource/folder");
this.startActivity(intent);
} else {
// Play store to install app
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" +
"com.estrongs.android.pop"));
this.startActivity(intent);
}

try this below code. if any file manager available , then it will pop up in a form of menu to choose appropriate for the user.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);

Open image from drawable into gallery intent

I would like to open just one image and have pitch-zoom function, so (as I think) easiest way to do that is to open that image in gallery intent. Anybody can share example of how to call gallery intent with particular picture from drawable?
I tried to used something like that but can't make it working (wrong file patch?).
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("com.me.example/drawable/thisimage.png"), "image/*");
startActivity(intent);

According to this post
You should do something like:
String uriStr = "android.resource://"+ "com.example.myapp"+ "/" + R.drawable.photo_h01;
Uri uri = Uri.parse(uriStr);
I have not Eclipse in front of me but that's what I have found on several sources

Android open folder image with built-in gallery

I want to open a images folder with android built-in gallery.
For example, I have a folder path that contains images, i want to open it with gallery.
I am using this code, it opens the gallery that contains no images.
Any idea?
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(folderImages)),"image/*");
startActivityForResult(intent, 1);

Maybe try this one:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), 1)
