Alternative to External Storage Android

In my app, I am calling camera that should capture picture and store it on given path:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
public static String pic_path =Environment.getExternalStorageDirectory().toString()+name;
File file = new File(pic_path);
Uri outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, REQUEST_CAMERA);
It works fine on devices that have SD card or any kind of External Storage. But it does not work on others (it crashes). So, what is alternative? How would I make this code work for devices without SD card/External Storage?

Displaying a specific folder of photos in the Android Gallery App

I'm looking to display a specific folder of images in an app so that the user can browse through them.
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("content://sdcard/Pictures/Album"), "image/*");
startActivityForResult(intent, 0);
This seems to display all photos on the phone instead of the images I have in this album. How can I change this code so that the user can browse through images in a specific folder using the gallery app? The idea behind this is not so that the user can choose an image like I've seen in many examples on here but just simply to browse the images.

you can try this
File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
Uri uri = Uri.fromFile(root);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(uri);
startActivityForResult(intent, 1);

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);

Pick Image From Android Device's Gallery App

In my android application, I implemented a feature to pick an image from Gallery. For that earlier I was doing this-
Intent pickImageIntent = new Intent(Intent.ACTION_GET_CONTENT);
pickImageIntent.setType("image/*");
startActivityForResult(pickImageIntent, GALLERY_REQUEST_CODE);
By doing this, a dialog with all available image source application like Dropbox including Native Gallery app were displayed and it asks to choose one. Then I changed to
Intent pickImageIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
pickImageIntent.setType("image/*");
startActivityForResult(pickImageIntent, GALLERY_REQUEST_CODE);
By doing this most of applications were not diplayed but still some like Picasa are diplayed. I want to pick an image from Device's native gallery app only or we can say from either device's internal or external memory not from any third party application.
If any one has solution for this please help me with that.

To pick image from Gallery only
Intent pickImageIntent = new Intent(Intent.ACTION_PICK);
pickImageIntent.setType("image/*");
startActivityForResult(pickImageIntent, GALLERY_REQUEST_CODE);
