How to use intent for choosing file browser to select file - android

How to use intent to prompt user to choose "finish action with" to choosing app to select file (assuming there is a few app to browse file in the device)
I want to filter the file using an extension.. (eg. : *.sav, *.props)
Thank you in advance


You can use something like this:
....
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, YOUR_RESULT_CODE);
....
But I really doubt that you can set a filter third-party file browsers.
Or you can try to use this file dialog: http://code.google.com/p/android-file-dialog/


this will open the build-in file explorer if available, otherwise will ask u to select a file explorer that u have installed.
private void showFileChooser() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
//intent.setType("*/*"); //all files
intent.setType("text/xml"); //XML file only
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"), FILE_SELECT_CODE);
} catch (android.content.ActivityNotFoundException ex) {
// Potentially direct the user to the Market with a Dialog
Toast.makeText(this, "Please install a File Manager.", Toast.LENGTH_SHORT).show();
}
}


It may help you to choose a doc file and u may change action as per your need
Intent intent;
if (VERSION.SDK_INT >= 19) {
intent = new Intent("android.intent.action.OPEN_DOCUMENT");
intent.setType("*/*");
} else {
PackageManager packageManager =getActivity().getPackageManager();
intent = new Intent("android.intent.action.GET_CONTENT");
intent.setType("file*//*");
if (packageManager.queryIntentActivities(intent,MEDIA_TYPE_IMAGE).size() == 0) {
UserToast.show(getActivity(), getResources().getString(R.string.no_file_manager_present));
}
}
if (getActivity().getPackageManager().resolveActivity(intent, NativeProtocol.MESSAGE_GET_ACCESS_TOKEN_REQUEST) != null) {
startActivityForResult(intent, UPLOAD_FILE);
}


// check here to KitKat or new version and this will solve the Samsung file explore issue too.
boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
if (isKitKat) {
Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent,FILE_SELECT_CODE);
} else {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(intent,FILE_SELECT_CODE);
}

How can I open the screenshot folder in internal memory using intent in android?

Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, READ_REQUEST_CODE);
I know how to bring the image from the gallery but how can I access the DCIM/ScreenShot from the Internal Storage

What you want is impossible using ACTION_OPEN_DOCUMENT_TREE.
The most you can get is the picker opening on the primary partion if it is an Android Q+ device.
But... For ACTION_OPEN_DOCUMENT you can put as extra in your intent an uri of a file the user choosed before.
Have a look at DocumentsContract.EXTRA_INITIAL_URI.

This might help:
Uri selectedUri = Uri.parse(context.getExternalFilesDir(
Environment.DIRECTORY_PICTURES+"/"));//make sure the path points to the exact folder where screenshot is saved as there is no fixed disrectory for screenshot
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "resource/folder");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}

There is a directory DIRECTORY_SCREENSHOTS but this require the minimum sdk level to 29
#RequiresApi(api = Build.VERSION_CODES.Q)
Uri uri = Uri.parse(context.getExternalFilesDir(
Environment.DIRECTORY_SCREENSHOTS+"/"));
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "resource/folder");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}

No Activity found to handle Intent android.intent.action.OPEN_DOCUMENT_TREE on Nokia 6.2 Android 9

it works perfectly on other phones, the problem is only with Nokia
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
activity.startActivityForResult(intent, CODE_REQUEST_OPEN_DOCUMENT_TREE);

it shows because your device hase no application for reading documents
put code as below for checking it
intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
try {
activity.startActivityForResult(intent, requestCode);
return;
} catch (ActivityNotFoundException anfe) {
Log.w(TAG, "couldn't complete ACTION_OPEN_DOCUMENT, no activity found. falling back.");
}
you can check more clearly by link2

Check if at least one activity exists to handle that Intent:
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
if (intent.resolveActivity(context.getPackageManager()) != null) {
activity.startActivityForResult(intent, CODE_REQUEST_OPEN_DOCUMENT_TREE);
}

Using Different type of Chooser to select document type. It is easy to use in android check Below code.
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);

How to open a folder create within application in android

I am generated a folder name "tesApplication" and create a file name "testFile.csc" in it and store some date into that file. Now I want to open folder dir using new intent.
I had try below code but did not work in my case any other way to achieve this.
Uri selectedUri = Uri.parse(fileNameString);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "text/csv");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}

copy this in else
public void openFolder()
{
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));
}

Is it possible to programmatically check if any file explorer is present on my Android device?

I'm trying to import a file into my application, below is the code :
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath());
intent.setDataAndType(uri, "*/*");
startActivityForResult(Intent.createChooser(intent, "Select File"),
REQUESTCODE);
What i want is that before firing the intent i want to programatically check whether any File explorer is present on my device or not? If yes then fire the intent but if no then i want to redirect user to Play store to download one, as it is mandatory for selecting a file. Is this feature possible to implement? Kindly enlighten me on this. Thanks in advance.

You can check if the file explorer is present or not using the below code, If not then ask user to download the app.
PackageManager packageManager = getActivity().getPackageManager();
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
List<ResolveInfo> list = packageManager.queryIntentActivities(intent,
PackageManager.GET_ACTIVITIES));
if (list.size > 0) {
// File explore is present (Size tells how many file explorers are present)
} else {
// Not present
// Just pointing to this app - https://play.google.com/store/apps/details?id=com.rhmsoft.fm
// You can choose whichever you need
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.rhmsoft.fm")));
} catch (android.content.ActivityNotFoundException e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=com.rhmsoft.fm")));
}
}

Android: How to open a specific folder via Intent and show its content in a file browser?

I thought this would be easy but as it turns out unfortunately it's not.
What I have:
I have a folder called "myFolder" on my external storage (not sd card because it's a Nexus 4, but that should not be the problem). The folder contains some *.csv files.
What I want:
I want to write a method which does the following: Show a variety of apps (file browsers) from which I can pick one (see picture). After I click on it, the selected file browser should start and show me the content of "myFolder". No more no less.
My question:
How exactly do I do that? I think I came quite close with the following code, but no matter what I do - and I'm certain that there must be something I didn't get right yet - it always opens only the main folder from the external storage.
public void openFolder()
{
File file = new File(Environment.getExternalStorageDirectory(),
"myFolder");
Log.d("path", file.toString());
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setDataAndType(Uri.fromFile(file), "*/*");
startActivity(intent);
}

This should help you:
Uri selectedUri = Uri.parse(Environment.getExternalStorageDirectory() + "/myFolder/");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "resource/folder");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}
Please, be sure that you have any file explorer app installed on your device.
EDIT: added a shantanu's recommendation from the comment.
LIBRARIES:
You can also have a look at the following libraries https://android-arsenal.com/tag/35 if the current solution doesn't help you.

I finally got it working. This way only a few apps are shown by the chooser (Google Drive, Dropbox, Root Explorer, and Solid Explorer). It's working fine with the two explorers but not with Google Drive and Dropbox (I guess because they cannot access the external storage). The other MIME type like "*/*" is also possible.
public void openFolder(){
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ File.separator + "myFolder" + File.separator);
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));
}

Here is my answer
private fun openFolder() {
val location = "/storage/emulated/0/Download/";
val intent = Intent(Intent.ACTION_VIEW)
val myDir: Uri = FileProvider.getUriForFile(context, context.applicationContext.packageName + ".provider", File(location))
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
intent.setDataAndType(myDir, DocumentsContract.Document.MIME_TYPE_DIR)
else intent.setDataAndType(myDir, "*/*")
if (intent.resolveActivityInfo(context.packageManager, 0) != null)
{
context.startActivity(intent)
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
CustomToast.toastIt(context,context.getString(R.string.there_is_no_file_explorer_app_present_text))
}
}
Here why I used FileProvider - android.os.FileUriExposedException: file:///storage/emulated/0/test.txt exposed beyond app through Intent.getData()
I tested on this device
Devices: Samsung SM-G950F (dreamltexx), Os API Level: 28

Intent chooser = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getDownloadCacheDirectory().getPath().toString());
chooser.addCategory(Intent.CATEGORY_OPENABLE);
chooser.setDataAndType(uri, "*/*");
// startActivity(chooser);
try {
startActivityForResult(chooser, SELECT_FILE);
}
catch (android.content.ActivityNotFoundException ex)
{
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
In code above, if setDataAndType is "*/*" a builtin file browser is opened to pick any file, if I set "text/plain" Dropbox is opened. I have Dropbox, Google Drive installed. If I uninstall Dropbox only "*/*" works to open file browser. This is Android 4.4.2. I can download contents from Dropbox and for Google Drive, by getContentResolver().openInputStream(data.getData()).

Thread is old but I needed this kind of feature in my application and I found a way to do it so I decided to post it if it can help anyone in my situation.
As our device fleet is composed only by Samsung Galaxy Tab 2, I just had to find the file explorer's package name, give the right path and I succeed open my file explorer where I wanted to. I wish I could use Intent.CATEGORY_APP_FILES but it is only available in API 29.
Intent intent = context.getPackageManager().getLaunchIntentForPackage("com.sec.android.app.myfiles");
Uri uri = Uri.parse(rootPath);
if (intent != null) {
intent.setData(uri);
startActivity(intent);
}
As I said, it was easy for me because our clients have the same device but it may help others to find a workaround for their own situation.

this code will work with OI File Manager :
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);
you can get OI File manager here : http://www.openintents.org/en/filemanager

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, DocumentsContract.Document.MIME_TYPE_DIR);
startActivity(intent);
Will open files app home screen

Today, you should be representing a folder using its content: URI as obtained from the Storage Access Framework, and opening it should be as simple as:
Intent i = new Intent(Intent.ACTION_VIEW, uri);
startActivity(i);

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("text/csv");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"), 0);
} catch (android.content.ActivityNotFoundException ex) {
ex.printStackTrace();
}
then you just need to add the response
public void onActivityResult(int requestCode, int resultCode, Intent data){
switch (requestCode) {
case 0: {
//what you want to do
//file = new File(uri.getPath());
}
}
}

You seem close.
I would try to set the URI like this :
String folderPath = Environment.getExternalStorageDirectory()+"/pathTo/folder";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
Uri myUri = Uri.parse(folderPath);
intent.setDataAndType(myUri , "file/*");
startActivity(intent);
But it's not so different from what you have tried.
Tell us if it changes anything ?
Also make sure the targeted folder exists, and have a look on the resulting Uri object before to send it to the intent, it may not be what we are expected.

File temp = File.createTempFile("preview", ".png" );
String fullfileName= temp.getAbsolutePath();
final String fileName = Uri.parse(fullfileName)
.getLastPathSegment();
final String filePath = fullfileName.
substring(0,fullfileName.lastIndexOf(File.separator));
Log.d("filePath", "filePath: " + filePath);
fullfileName:
/mnt/sdcard/Download_Manager_Farsi/preview.png
filePath:
/mnt/sdcard/Download_Manager_Farsi
