You can use this lightweight library to implement the attachment feature (taking pictures using the camera, picking up files/images from gallery or file system, or google drive). The library helps you to simplify all the processes related to picking files without worrying about system permissions

Language Support

• English
• Arabic

Warning!

1. This library is build using AndroidX.So, I recommend you to migrate your project to AndroidX otherwise it may cause problem using both androidx and support libs togather.

2. You might face error Invoke-customs are only supported starting with android 0 --min-api 26 .To solve this add below lines in app level build.gradle file.

compileOptions {
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }

Prerequisite

1. Add permissions and provider in AndroidManifest.xml

      <uses-permission android:name="android.permission.READ_STORAGE_PERMISSION" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"
        android:maxSdkVersion="32" />
    <uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />

    <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
    <uses-permission android:name="android.permission.CAMERA" />

 <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.attachmentmanager"
            android:exported="false"
            android:grantUriPermissions="true"
            tools:replace="android:authorities">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_provider"
                tools:replace="android:resource" />
  </provider>

1. Create file_provider.xml in res/xml

   <?xml version="1.0" encoding="utf-8"?>
   <paths>
    <external-path
        name="myApp"
        path="Download/" />
    <external-files-path
        name="images"
        path="Pictures" />
   </paths>
   

2. If you are targeting Android 11+, you need to add following queries in AndroidManifest.xml

   <queries>
        <intent>
            <action android:name="android.intent.action.OPEN_DOCUMENT" />
            <!-- If you don't know the MIME type in advance, set "mimeType" to "*/*". -->
            <data android:mimeType="*/*" />
        </intent>
        <intent>
            <action android:name="android.intent.action.PICK" />
            <!-- If you don't know the MIME type in advance, set "mimeType" to "*/*". -->
            <data android:mimeType="*/*" />
        </intent>
    </queries>
   

3. Update project level build.gradle file.

   allprojects {
   repositories {
          jcenter()
           maven { url "https://jitpack.io" }  //Make sure to add this in your project
   }
   }
   

   implementation 'com.github.Zaid-Mirza:AttachmentManager:3.0.0'

Usage

1. Initiate AttachmentManager object using builder pattern

   Kotlin

private var attachmentManager: AttachmentManager? = null
var gallery = arrayOf("image/png",
            "image/jpg",
            "image/jpeg")
    var files = arrayOf("application/msword",
            "application/vnd.openxmlformats-officedocument.wordprocessingml.document",  // .ppt & .pptx
            "application/pdf")

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

      attachmentManager = AttachmentManager.AttachmentBuilder(this) // must pass Context
            .fragment(null) // pass fragment reference if you are in fragment
            .setUiTitle("Choose File") // title of dialog or bottom sheet
            .allowMultiple(false) // set true if you want make multiple selection, default is false
            .asBottomSheet(true) // set true if you need to show selection as bottom sheet, default is as Dialog
            .setOptionsTextColor(android.R.color.holo_green_light) // change text color
            .setImagesColor(R.color.colorAccent) // change icon color
            .hide(HideOption.DOCUMENT) // You can hide any option do you want
            .setMaxPhotoSize(200000) // Set max  photo size in bytes
            .galleryMimeTypes(gallery) // mime types for gallery
            .filesMimeTypes(files) // mime types for files
            .build(); // Hide any of the three options

    }

Java

    private AttachmentManager attachmentManager = null;
    String[] gallery = {"image/png",
            "image/jpg",
            "image/jpeg"};
    String[] files  = { "application/msword",
            "application/vnd.openxmlformats-officedocument.wordprocessingml.document", // .ppt & .pptx
            "application/pdf"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       attachmentManager = new AttachmentManager.AttachmentBuilder(this) // must pass Context
                .fragment(null) // pass fragment reference if you are in fragment
                .setUiTitle("Choose File") // title of dialog or bottom sheet
                .allowMultiple(false) // set true if you want make multiple selection, default is false
                .asBottomSheet(true) // set true if you need to show selection as bottom sheet, default is as Dialog
                .setOptionsTextColor(android.R.color.holo_green_light) // change text color
                .setImagesColor(R.color.colorAccent) // change icon color
                .hide(HideOption.DOCUMENT) // You can hide any option do you want
                .setMaxPhotoSize(200000) // Set max  photo size in bytes
                .galleryMimeTypes(gallery) // mime types for gallery
                .filesMimeTypes(files) // mime types for files
                .build(); // Hide any of the three options
    }

1. Declare registerForActivityResult

Kotlin

 private var mLauncher = registerForActivityResult(StartActivityForResult()) { result ->

    val list =  attachmentManager?.manipulateAttachments(this,result.resultCode,result.data)
    Toast.makeText(this, list?.size.toString(), Toast.LENGTH_LONG).show()
}
`

Java

 ActivityResultLauncher<Intent> mLauncher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), result -> {

        ArrayList<AttachmentDetail> list = attachmentManager.manipulateAttachments(this,result.getResultCode(),result.getData());

        });

1. Call openSelection() method to show selection UI and pass ActivityResultLauncher

Kotlin

 attachmentManager?.openSelection(mLauncher)
`

Java

attachmentManager.openSelection(mLauncher);

1. Override onRequestPermissionsResult (Optional)

Kotlin

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
        attachmentManager?.handlePermissionResponse(requestCode, permissions, grantResults)
    }

Java

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        attachmentManager.handlePermissionResponse(requestCode,permissions,grantResults);
    }

Other Usage

1. You can open gallery,camera or file system directly without showing selection UI to user

Kotlin

 attachmentManager?.startCamera(mLauncher)
 // OR
 attachmentManager?.openGallery(mLauncher)
 // OR
 attachmentManager?.openFilSystem(mLauncher)

Java

 attachmentManager.startCamera(mLauncher);
 // OR
 attachmentManager.openGallery(mLauncher);
 // OR
 attachmentManager.openFilSystem(mLauncher);
