FileBrowser

A FileBrowser / FileChooser for Android that you can integrate to your app to browse/select files from internal/external storage.

Using Maven

<dependency>
  <groupId>com.adityak</groupId>
  <artifactId>browsemyfiles</artifactId>
  <version>1.7</version>
  <type>pom</type>
</dependency>

Or Using Gradle

compile 'com.adityak:browsemyfiles:1.7'

It easily integrates with your app's color scheme. You can change the color scheme using the following in your styles.xml

<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="android:actionModeBackground">@color/actionModeToolbar</item>

There are 3 main classes to use the library.

  1. FileBrowser - Used to just Browse files in storage (has all file IO features)
  2. FileChooser - Used to select single/multiple files in storage (has some IO features)
  3. FileBrowserWithCustomHandler - Used to run custom code when files are selected (has all IO features)

1. FileBrowser

Use following Intent to start the FileBrowser

Intent i4 = new Intent(getApplicationContext(), FileBrowser.class);
startActivity(i4);

2. FileChooser

Use following Intent to start the FileChooser

  • For Single Selection
Intent i2 = new Intent(getApplicationContext(), FileChooser.class);
i2.putExtra(Constants.SELECTION_MODE,Constants.SELECTION_MODES.SINGLE_SELECTION.ordinal());
startActivityForResult(i2,PICK_FILE_REQUEST);

To get the selected file, In your calling activity's onActivityResult method, use the following

if (requestCode == PICK_FILE_REQUEST && data!=null) {
      if (resultCode == RESULT_OK) {
          Uri file = data.getData();
      }
}
        
  • For Multiple Selection
Intent i2 = new Intent(getApplicationContext(), FileChooser.class);
i2.putExtra(Constants.SELECTION_MODE,Constants.SELECTION_MODES.MULTIPLE_SELECTION.ordinal());
startActivityForResult(i2,PICK_FILE_REQUEST);

To get the selected file, In your calling activity's onActivityResult method, use the following

if (requestCode == PICK_FILE_REQUEST && data!=null) {
      if (resultCode == RESULT_OK) {
          ArrayList<Uri> selectedFiles  = data.getParcelableArrayListExtra(Constants.SELECTED_ITEMS);
      }
}
        

3. FileBrowserWithCustomHandler

Register a Broadcast receiver and handle the onReceive method like below

public class FileSelectedBroadCastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
         Uri filePath = intent.getParcelableExtra(com.aditya.filebrowser.Constants.BROADCAST_SELECTED_FILE);
    }
}

Register the receiver like the following snippet

        <receiver android:name=".FileSelectedBroadCastReceiver"
            android:exported="false"
            android:enabled="true">
            <intent-filter>
                <action android:name="com.adityak.filebrowser.FILE_SELECTED_BROADCAST" />
            </intent-filter>
        </receiver>
        

If you also need some other parameters to be sent with the broadcast use the following when creating the activity

Intent i = new Intent(mContext, FileBrowserWithCustomHandler.class);
Bundle ib = new Bundle();
//add extras
i.putExtras(ib);
startActivity(i);

and in the broadcast receiver use the following to get the extras

Bundle b = intent.getExtras()

To load a particular directory instead of the normal root directory

Add the following in the intent

Intent i = new Intent(this, FileBrowser.class); //works for all 3 main classes (i.e FileBrowser, FileChooser, FileBrowserWithCustomHandler)
i.putExtra(Constants.INITIAL_DIRECTORY, new File(Environment.getExternalStorageDirectory().getAbsolutePath(),"Movies").getAbsolutePath());

To list only the files with a particular extension

Add the following in the intent

Intent i = new Intent(this, FileBrowser.class); //works for all 3 main classes (i.e FileBrowser, FileChooser, FileBrowserWithCustomHandler)
i.putExtra(Constants.ALLOWED_FILE_EXTENSIONS, "mkv;mp4;avi");

Use file extensions delimited by semicolon

Known Issues

Currently folder size is calculated using Java's Api getTotalSpace() which gives the size of the partition of the path which may not always give the desired result. To get the exact size, properties can be used which gives the exact result. If Exact size is to be known, then UI would lag as it would take some time to calculate size - Fix for this is postponed
