MediaPickerConfig: It is use to set the configuration. 1. **.setAllowMultiSelection(booleanValue)**: tells whether to select single file or multiple file. 2. **.setUriPermanentAccess(booleanValue)**: grant uri access permission. * Temporary uri may not work once your app terminates(so storaring temporary uri in database is not good practise, so use permanent uri in such case). * This option only works while selecting file from default android intent. * The file user select from our custom ui always return uri with permanent access grant. 3. **.setShowConfirmationDialog(booleanValue)**: tells whether to show confirmation dialog on selecting the file(only work in single file selection). eg. ```java //Pick single file with permanent access uri and confirmation dialog MediaPickerConfig pickerConfig = new MediaPickerConfig() .setAllowMultiSelection(false) .setUriPermanentAccess(true) .setShowConfirmationDialog(true) .setScreenOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); ``` #### 2. ExtraListener: In Android many times the file not exist physically but may contain uri. Such file(uri) may produce error. So in our library we are filtering out invalid uri. So if end-developer wants to know if library filtered out uris, they can set ```.setFileMissingListener()```. #### Java ```java .setFileMissingListener(new MediaPicker.MediaPickerImpl.OnMediaListener() { @Override public void onMissingFileWarning() { //trigger when some missing file are filtered out } }) ``` #### Kotlin ```kotlin .setFileMissingListener(object : MediaPicker.MediaPickerImpl.OnMediaListener{ override fun onMissingFileWarning() { //trigger when some missing file are filtered out } }) ``` #### 3. Media types: It's a type of file user want to select. 1. **IMAGE** : for picking image files 2. **VIDEO** : for picking video files 3. **AUDIO** : for picking audio files ### URI: We will be returning the list of Uri after selecting the files. That's why it is better to know about Uri first. A Uniform Resource Identifier (URI) is a compact sequence of characters that identifies an abstract or physical resource. In Android, Content providers manage access to a structured set of data. They encapsulate the data, and provide mechanisms for defining data security. Content providers are the standard interface that connects data in one process with code running in another process. You can get almost all information from uri. #### URI usages: 1. Get file from uri: ```java File file = new File(uri.getPath()); ``` 2. Get mime from uri: ```java String mimeType = getContentResolver().getType(uri); ``` 3. Used in Glide: ```java Glide.with(context) .load(uri) .into(imageView); ``` --- ### Quick Links * [ChangeLog](/CHANGELOG.md) * [Documentation](https://github.com/Turtlebody/android-media-picker/wiki) ### Demos * [Example](/Example.md) * [Sample APK file](https://play.google.com/store/apps/details?id=com.greentoad.turtlebody.mediapicker.sample) ### Developers * [API Documentation](https://github.com/Turtlebody/android-media-picker/wiki/API-Documentation) * [Developer Setup & Usage](https://github.com/Turtlebody/android-media-picker/wiki/Developer-Setup) --- ## To pick more type of files like doc, ppt, txt etc. you can use [Turtlebody Doc Picker](https://github.com/Turtlebody/android-doc-picker) library.
