Android: make internal file picker available as a choice - android

When opening a file picker with the following method:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
Intent chooserIntent = Intent.createChooser(intent, "Open file");
startActivityForResult(chooserIntent, REQUEST_CODE_FILE_PICKER);
unless a default has been set, this will present the user with a choice of file pickers to use. How do you make your own, internal, file chooser available as one of the choices of file pickers presented to the user (such as the Material File Picker)?


Thanks to #CommonsWare's comment, here is the extra bit of code needed to add the internal file picker to the list of choices presented to the user:
// this bit is as before...
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
Intent chooserIntent = Intent.createChooser(intent, "Open file");
// new bit... create Intent for the internal file picker...
Intent materialFilePickerIntent = new Intent(this, FilePickerActivity.class);
materialFilePickerIntent.putExtra(FilePickerActivity.ARG_FILE_FILTER, Pattern.compile(".*\\.txt$"));
// and add the picker to the list...
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { materialFilePickerIntent });
// finally, startActivityForResult() as before...
startActivityForResult(chooserIntent, REQUEST_CODE_FILE_PICKER);

Intent to pick file from the specified directory in internal storage

I need to create Intent which will show me a file picker to choose files inside the specified folder. I used this approach:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri selectedUri = Uri.parse(getFilesDir().getAbsolutePath() + "/FILES");
intent.setDataAndType(selectedUri, "*/*");
startActivityForResult(intent, SCRIPT_REQUEST_CODE);
But this didn't open the desired folder.
Can somebody tell how to open the file picker in the specified folder?
UPD: Tried this as were suggested in comments but I can't pick the desired file type with such type in intent.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, YOUR_RESULT_CODE);

How to choose only doc,docx files through intent?

I'm using Intent to open file manager, I need to know how to show only .doc, .docx files to choose by users. How to put setType to intent?`
The Following function is used to choose file from file manager.
private void showFileChooser() {
Intent intent = new Intent();
//sets the select file to all types of files
intent.setType("application/*");
//allows to select data and return it
intent.setAction(Intent.ACTION_GET_CONTENT);
//starts new activity to select file and return data
startActivityForResult(Intent.createChooser(intent, "Choose File to Upload.."), PICK_FILE_REQUEST);
}`

You can add multiple mime types like this:
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
String[] mimetypes = {"application/vnd.openxmlformats-officedocument.wordprocessingml.document", "application/msword"};
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
startActivityForResult(intent, REQUEST_CODE_OPEN);
Following mime types corespond to .docx and .doc files
String[] mimetypes = {"application/vnd.openxmlformats-officedocument.wordprocessingml.document", "application/msword"};

Open image for sharing

I have Android Xamarin application with imageview
OnClik I lunch intent to preview image
File file = new File(photoPath);
Intent intent = new Intent(Intent.ActionView);
intent.SetDataAndType(Uri.FromFile(file), "image/*");
intent.SetFlags(ActivityFlags.NoHistory);
StartActivity(intent);
from apps I choose 'Gallery'
when the image is opend there are no sharing options
when I open image from device 'Gallery' has sharing options
Image is saved to SD card before preview.
what am I doing wrong ?

solution that worked for me
Intent intent = new Intent();
intent.PutExtra(Intent.ActionView, photoPath);
intent.SetType("image/*");
StartActivity(Intent.CreateChooser(intent, "Select Picture"));
now I get my image opend in gallery and I can use sharing options too

Do it using Intent.ACTION_SEND and you'll get that sharing option.
Also try with Intent.ACTION_GET_CONTENT.
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), 1);

Select File from file manager via Intent

What I wanna do:
I wanna get the path as a String of a file, which I choose via an Android File Manager.
What I have:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(Intent.createChooser(intent, "Open with ..."), FILE_SELECT_CODE);
This code, works nearly fine for me, but there is one problem. I can only select my file with the following apps:
My Question:
Does anyone have a working code for choosing any file via the Android File Manager?

You can use this:
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
startActivityForResult(intent, REQUEST_CODE);
For samsung devices to open file manager use this:
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
intent.addCategory(Intent.CATEGORY_DEFAULT);
For more reference checkout http://developer.android.com/guide/topics/providers/document-provider.html

So for my Samsung device this worked:
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
intent.addCategory(Intent.CATEGORY_DEFAULT);
startActivityForResult(intent, FILE_SELECT_CODE);

Pick any kind of file via an Intent in Android

I would like to start an intentchooser for apps which can return any kind of file
Currently I use (which I copied from the Android email source code for file attachment)
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
Intent i = Intent.createChooser(intent, "File");
startActivityForResult(i, CHOOSE_FILE_REQUESTCODE);
But it only shows "Gallery" and "Music player" on my Galaxy S2. There is a file explorer on this device and I would like it to appear in the list. I would also like the camera app to show in the list, so that the user can shoot a picture and send it through my app.
If I install Astro file manager it will respond to that intent, too. My customers are Galaxy SII owners only and I don't want to force them to install Astro file manager given that they already have a basic but sufficient file manager.
Any idea of how I could achieve this ? I am pretty sure that I already saw the default file manager appear in such a menu to pick a file, but I can't remember in which app.

Not for camera but for other files..
In my device I have ES File Explorer installed and This simply thing works in my case..
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, PICKFILE_REQUEST_CODE);

Samsung file explorer needs not only custom action (com.sec.android.app.myfiles.PICK_DATA),
but also category part (Intent.CATEGORY_DEFAULT) and mime-type should be passed as extra.
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
intent.addCategory(Intent.CATEGORY_DEFAULT);
You can also use this action for opening multiple files: com.sec.android.app.myfiles.PICK_DATA_MULTIPLE
Anyway here is my solution which works on Samsung and other devices:
public void openFile(String mimeType) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(mimeType);
intent.addCategory(Intent.CATEGORY_OPENABLE);
// special intent for Samsung file manager
Intent sIntent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
// if you want any file type, you can skip next line
sIntent.putExtra("CONTENT_TYPE", mimeType);
sIntent.addCategory(Intent.CATEGORY_DEFAULT);
Intent chooserIntent;
if (getPackageManager().resolveActivity(sIntent, 0) != null){
// it is device with Samsung file manager
chooserIntent = Intent.createChooser(sIntent, "Open file");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { intent});
} else {
chooserIntent = Intent.createChooser(intent, "Open file");
}
try {
startActivityForResult(chooserIntent, CHOOSE_FILE_REQUESTCODE);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(getApplicationContext(), "No suitable File Manager was found.", Toast.LENGTH_SHORT).show();
}
}
This solution works well for me, and maybe will be useful for someone else.

this work for me on galaxy note
its show
contacts,
file managers installed on device,
gallery,
music player
private void openFile(Int CODE) {
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.setType("*/*");
startActivityForResult(intent, CODE);
}
here get path in onActivityResult of activity.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
String Fpath = data.getDataString();
// do somthing...
super.onActivityResult(requestCode, resultCode, data);
}

This gives me the best result:
Intent intent;
if (android.os.Build.MANUFACTURER.equalsIgnoreCase("samsung")) {
intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
intent.addCategory(Intent.CATEGORY_DEFAULT);
} else {
String[] mimeTypes =
{"application/msword", "application/vnd.openxmlformats-officedocument.wordprocessingml.document", // .doc & .docx
"application/vnd.ms-powerpoint", "application/vnd.openxmlformats-officedocument.presentationml.presentation", // .ppt & .pptx
"application/vnd.ms-excel", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", // .xls & .xlsx
"text/plain",
"application/pdf",
"application/zip", "application/vnd.android.package-archive"};
intent = new Intent(Intent.ACTION_GET_CONTENT); // or ACTION_OPEN_DOCUMENT
intent.setType("*/*");
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
}

Turns out the Samsung file explorer uses a custom action. This is why I could see the Samsung file explorer when looking for a file from the samsung apps, but not from mine.
The action is "com.sec.android.app.myfiles.PICK_DATA"
I created a custom Activity Picker which displays activities filtering both intents.

If you want to know this, it exists an open source library called aFileDialog that it is an small and easy to use which provides a file picker.
The difference with another file chooser's libraries for Android is that aFileDialog gives you the option to open the file chooser as a Dialog and as an Activity.
It also lets you to select folders, create files, filter files using regular expressions and show confirmation dialogs.

The other answers are not incorrect. However, now there are more options for opening files. For example, if you want the app to have long term, permanent acess to a file, you can use ACTION_OPEN_DOCUMENT instead. Refer to the official documentation: Open files using storage access framework. Also refer to this answer.
