android-smbfile-chooser

android-file-library is a lightweight file/folder chooser. This (android-smbfile-chooser) is my attempt to add the ability to use jcifs.smb.SmbFile to browse a Windows shared directory.

FileChooserDialog DEPRECATED!

This library contains a file chooser for both android storage, and external windows smb shared storage. Begining from Android R, FileChooserDialog which was a file chooser for android will no longer work!

Snapshots

Demo Application

A demo-app of the original can be installed from Play Store.

NOTE:

Please don't forget to check the upstream and give it a ⭐!
You can also support him via opencollective and paypal.

If you are using a different Support library, then use this:

configurations.all {
    resolutionStrategy.force 'com.android.support:appcompat-v7:x.y.z'
}

1.2.0 used jcifs 1.3.17, which only supports SMB1.
1.3.0 however switched to an open source, maintained jcifs-ng which is a breaking change! This one fully supports SMB2, and partially SMB3. Also, target sdk was bumped to 1.8:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Usage

SmbFileChooserDialog.newDialog(context, "**.***.*.**", authenticator)
    .setResources("select a directory", "choose", "cancel")
    .setFilter(/*only directories (no files)*/ true, /*don't show hidden files/folders*/ false)
    .setOnChosenListener((path, file) -> {
        String msg = "error";
        try{
            msg = file.isDirectory() ? "directory" : "file" + " selected: " + path
        } catch(SmbException e){
            e.printStackTrace();
        }
        // This is NOT main UI thread. you can NOT access SmbFiles on UI thread.
        Handler mainHandler = new Handler(context.getMainLooper());
        mainHandler.post(() -> {
            Toast.makeText(context,
                msg,
                Toast.LENGTH_SHORT)
            .show();
        });
    })
    .setExceptionHandler((exception, id) -> {
        Toast.makeText(context, exception.getMessage(), Toast.LENGTH_LONG).show();
        return true;
    })
    .show();

Additional options

.displayPath(/*displays the current path in the title (title must be enabled)*/ true)
.enableOptions(/*enables 'New folder' and 'Delete'*/ true)
.setOptionResources("New folder", /*only on `SmbFileChooserDialog`*/ "Refresh", "Delete", "Cancel", "OK")
.setNewFolderFilter(new NewFolderFilter(/*max length of 10*/ 10, /*regex pattern that only allows a to z (lowercase)*/ "^[a-z]*$"))
.enableMultiple(/*enables the ability to select multiple*/ true, /*allows selecting folders along with files*/ true)
.setOnSelectedListener(/*this gets called, when user selects more than 1 file*/ (files) -> {
    ArrayList<String> paths = new ArrayList<String>();
    for (SmbFile file : files) paths.add(file.getPath());
    AlertDialog.Builder dialog = new AlertDialog.Builder(context);
    dialog.setTitle("Selected files:");
    dialog.setAdapter(new ArrayAdapter<String>(context, android.R.layout.simple_expandable_list_item_1, paths) , null);
    dialog.show();
})
.enableDpad(/*enables Dpad controls (mainly for Android TVs)*/ true)
.cancelOnTouchOutside(true)
.setTheme(R.style.FileChooserStyle)
.setAdapterSetter(adapter -> {
    adapter.overrideGetView(
        (file, isSelected, convertView, parent, inflater) -> { 
            // inflate and return view. SmbFile should not be accessed on the main thread!
            return convertView;
        }, (file, isSelected, view) -> { 
            // modify view. only available if SmbFileChooserDialog is being used.
        });
})

What's Different?

I replaced all methods "with___()" with "set___()"! And, use static method "newDialog(context)" instead of a constructor.

• there are no public constructors. Instead use static methods:

FileChooserDialog.newDialog(context)

• when multiple files are selected, a new listener is called:

FileChooserDialog.setOnSelectedListener(files -> {
    ArrayList<String> paths = new ArrayList<>();
    for (File file : files) {
        paths.add(file.getPath());
    }

    new AlertDialog.Builder(context)
        .setTitle(files.size() + " files selected:")
        .setAdapter(new ArrayAdapter<>(context,
            android.R.layout.simple_expandable_list_item_1, paths), null)
        .create()
        .show();
});

• there's no titleFollowsDir option, and displayPath is false by default
• in SmbFileChooserDialog use setExceptionHandler to handle exceptions

interface ExceptionHandler {
    /**
     * @return true to attempt to terminate.
     * false to attempt to ignore exception and continue
     */
    boolean handle(Throwable exception, int id);
}
