Android-FilePicker (Androidx based)

A filepicker which allows to select images and videos with flexibility. It also supports selection of files by specifying its file type. For using this library, you have to migrate your project to androidx or you can use older version(2.1.5). Check out app module for example.

For Android 10 devices using document picker, you will need to enable android:requestLegacyExternalStorage="true" option in your manifest file. This document picker will get deprecated soon over scoped storage and also, this flag will not work in Android 11. :/

Installation

• As of now, It is only available in jCenter(), So just put this in your app dependencies:

    implementation 'com.droidninja:filepicker:2.2.4'

There is a method getFilePath in ContentUriUtils class through you can get the file path from Uri. e.g.

Java:

ContentUriUtils.INSTANCE.getFilePath(getContext(), uri);

Kotlin

ContentUriUtils.getFilePath(context, uri);

Note

This Filepicker is based on the MediaStore api provided by android. It checks MediaStore database for a file entry. If your file is not showing in the picker, it means that it is not inserted into MediaStore database yet.

Usage

Just include this in your onclick function:

• For photopicker:

FilePickerBuilder.getInstance()
               .setMaxCount(5) //optional
               .setSelectedFiles(filePaths) //optional
               .setActivityTheme(R.style.LibAppTheme) //optional
               .pickPhoto(this);

If you want to use custom request code, you just have to like this:

FilePickerBuilder.getInstance()
               .setMaxCount(5) //optional
               .setSelectedFiles(filePaths) //optional
               .setActivityTheme(R.style.LibAppTheme) //optional
               .pickPhoto(this, CUSTOM_REQUEST_CODE);

• For document picker:

 FilePickerBuilder.getInstance()
               .setMaxCount(10) //optional
               .setSelectedFiles(filePaths) //optional
               .setActivityTheme(R.style.LibAppTheme) //optional
               .pickFile(this);

If you want to use custom request code, you just have to like this:

FilePickerBuilder.getInstance()
               .setMaxCount(5) //optional
               .setSelectedFiles(filePaths) //optional
               .setActivityTheme(R.style.LibAppTheme) //optional
               .pickFile(this, CUSTOM_REQUEST_CODE);

After this, you will get list of file paths in activity result:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
           switch (requestCode)
           {
               case FilePickerConst.REQUEST_CODE_PHOTO:
                   if(resultCode== Activity.RESULT_OK && data!=null)
                   {
                       photoPaths = new ArrayList<>();
                       photoPaths.addAll(data.getParcelableArrayListExtra<Uri>(FilePickerConst.KEY_SELECTED_MEDIA));
                   }
                   break;
               case FilePickerConst.REQUEST_CODE_DOC:
                   if(resultCode== Activity.RESULT_OK && data!=null)
                   {
                       docPaths = new ArrayList<>();
                       docPaths.addAll(data.getParcelableArrayListExtra<Uri>(FilePickerConst.KEY_SELECTED_DOCS));
                   }
                   break;
           }
           addThemToView(photoPaths,docPaths);
       }

Builder Methods

Android FilePicker now has more flexibility. Supported builder methods are:

If you want to add custom file type picker(do not use . in extension types), use addFileSupport() method like this ( for zip support):

String zipTypes = {"zip","rar"};
   addFileSupport("ZIP",zipTypes, R.drawable.ic_zip_icon);

Styling

Just override these styles in your main module to change colors and themes

<style name="LibAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:colorBackground">@android:color/background_light</item>
        <item name="android:windowBackground">@android:color/white</item>
    </style>

    <style name="PickerTabLayout" parent="Widget.Design.TabLayout">
        <item name="tabBackground">@color/colorPrimary</item>
        <item name="tabGravity">fill</item>
        <item name="tabMaxWidth">0dp</item>
    </style>
    
    <style name="SmoothCheckBoxStyle">
        <item name="color_checked">@color/checkbox_color</item>
        <item name="color_unchecked">@android:color/white</item>
        <item name="color_unchecked_stroke">@color/checkbox_unchecked_color</item>
        <item name="color_tick">@android:color/white</item>
    </style>
