AsyncFilePicker

!!! Some features may work unstable, make sure you have tested it. Thanks.

Feel free to fork or issue pull requests on github. Issues can be reported on the github issue tracker.

File picker allows you to take photo and files from camera\gallery\filesystem and also you can add up to 3 own custom actions.

Picker will ask for camera and gallery permission on android version 6.0 or above.

Install

To add this library to your project, you must add the JitPack repo to your root build.gradle file...

allprojects {
 repositories {
    ...
    jcenter()
 }
}

Then include this in your dependencies block

implementation 'org.shagi:filepicker:0.4'

Usage

  1. Add permissions and provider block to your's AndroidManifest.xml
    <uses-permission android:name="android.permission.CAMERA"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"/>
        </provider>
  1. Create file provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
    <files-path name="files_picked" path="picked" />
</paths>
  1. For simple use instantiate FilePickerFragment and in OnClick method pass FilePickerDialog into fragment.

ExtFile - wrapper object for File object with additional data such as (baseUri, mimeType, fileName)

Note: By default cache is not used and each time you take photo or file it will have same name, so Picasso or other image loading libraries can cache the first image by filename. To avoid that you can to save received file by yourself or use cache in FilePickerFragment or use memoryPolicy(MemoryPolicy.NO_CACHE) in Picasso.

        val pickerFragment = FilePickerFragment.getFragment(supportFragmentManager, useCache)
        view.setOnClickListener {
                    pickerFragment.use(FilePickerDialog.newInstance())
                    pickerFragment.setOnLoadingListener(object : FilePicker.OnLoadingListener {
                        override fun onLoadingStart(key: Long) {
                            imageView.setImageResource(R.color.colorAccent)
                            textView.text = "loading"
                        }
        
                        override fun onLoadingSuccess(key: Long, file: ExtFile) {
                            textView.text = file.toString()
                            
                            Picasso.get()
                               .load(file.file)
                               .memoryPolicy(MemoryPolicy.NO_CACHE)
                               .into(imageView)
                        }
        
                        override fun onLoadingFailure(key: Long, throwable: Throwable) {
                            textView.text = throwable.message
                        }
        
                    })
                    pickerFragment.show()
                }

Available functions

Customisation

You can customise picker dialog with own layout. Override onCreateView method and pass there layout with same view ids as in base FilePickerDialog layout - file_picker_dialog_layout

class CustomPicker : FilePickerDialog() {

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View =
            inflater.inflate(R.layout.file_picker_layout, container, false)

}

Cache and Settings

By default each file and photo returned overrides one temp file, and you have to save this file by yourself.

If you want to upload multiple at one time you can turn cache on by passing true as second param to FilePickerFragment.getFragment(fm,useCache).

You can setup maxCacheSize, maxFileSize, maxWidth, maxHeight use FilePickerFragment.setup(FilePickerSettings) method

        val pickerFragment = FilePickerFragment.getFragment(supportFragmentManager, true).apply { 
            use(initFilePickerDialog())
            setup(settings)
        }
    private fun initFilePickerDialog() =
            if (useCustomLayout) { // to user Custom Picker
                CustomPicker()
            } else {
                FilePickerDialog.newInstance()
            }.apply {
                showCamera = !cameraDisabled // to show camera picker row
                showGallery = !galleryDisabled // to show gallery picker row
                showFileSystem = !filesDisabled // to show file system picker row

                if (!customActionDisabled) { // to use custom action
                    addCustomAction(CustomActionItem(R.drawable.file_picker_ic_folder,
                            R.string.fpd_load_from_medical_note_documents,
                            View.OnClickListener {
                                Toast.makeText(context, "Custom action clicked", Toast.LENGTH_SHORT).show()
                            })
                    )
                }
            }
