<activity
android:name="com.dropbox.core.android.AuthActivity"
android:configChanges="orientation|keyboard"
android:launchMode="singleTask">
<intent-filter>
<!-- Change this to be db- followed by your app key -->
<data android:scheme="db-DROPBOXKEY" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

For iOS,
-
add below in Info.plist
<key>LSApplicationQueriesSchemes</key> <array> <string>dbapi-8-emm</string> <string>dbapi-2</string> </array>
-
add below in Info.plist (replace DROPBOXKEY with your key)
<key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleURLSchemes</key> <array> <string>db-DROPBOXKEY</string> </array> <key>CFBundleURLName</key> <string></string> </dict> </array>
3.a) If you are using Swift, add below code to AppDelegate.swift
import ObjectiveDropboxOfficial
// should be inside AppDelegate class
override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
if let authResult = DBClientsManager.handleRedirectURL(url) {
if authResult.isSuccess() {
print("dropbox auth success")
} else if (authResult.isCancel()) {
print("dropbox auth cancel")
} else if (authResult.isError()) {
print("dropbox auth error \(authResult.errorDescription)")
}
}
return true
}
// if your are linked with ObjectiveDropboxOfficial 6.x use below code instead
override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
DBClientsManager.handleRedirectURL(url, completion:{ (authResult) in
if let authResult = authResult {
if authResult.isSuccess() {
print("dropbox auth success")
} else if (authResult.isCancel()) {
print("dropbox auth cancel")
} else if (authResult.isError()) {
print("dropbox auth error \(authResult.errorDescription)")
}
}
});
return true
}
3.b) If you are using Objective C, add below code to AppDelegate.m
#import <ObjectiveDropboxOfficial/ObjectiveDropboxOfficial.h>
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
DBOAuthResult *authResult = [DBClientsManager handleRedirectURL:url];
if (authResult != nil) {
if ([authResult isSuccess]) {
NSLog(@"Success! User is logged into Dropbox.");
} else if ([authResult isCancel]) {
NSLog(@"Authorization flow was manually canceled by user!");
} else if ([authResult isError]) {
NSLog(@"Error: %@", authResult);
}
}
return NO;
}
// if your are linked with ObjectiveDropboxOfficial 6.x use below code instead
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
BOOL result = [DBClientsManager handleRedirectURL:url completion: ^(DBOAuthResult *authResult) {
if (authResult != nil) {
if ([authResult isSuccess]) {
NSLog(@"Success! User is logged into Dropbox.");
} else if ([authResult isCancel]) {
NSLog(@"Authorization flow was manually canceled by user!");
} else if ([authResult isError]) {
NSLog(@"Error: %@", authResult);
}
}
}];
return NO;
}

import 'package:dropbox_client/dropbox_client.dart';
Future initDropbox() async {
// init dropbox client. (call only once!)
await Dropbox.init(dropbox_clientId, dropbox_key, dropbox_secret);
}
// Legacy Authorization
String accessToken;
Future testLogin() async {
// this will run Dropbox app if possible, if not it will run authorization using a web browser.
await Dropbox.authorize();
}
Future getAccessToken() async {
accessToken = await Dropbox.getAccessToken();
}
Future loginWithAccessToken() async {
await Dropbox.authorizeWithAccessToken(accessToken);
}
Future testLogout() async {
// unlink removes authorization
await Dropbox.unlink();
}
// OAuth 2 code flow with PKCE that grants a short-lived token
String credentials;
Future testLogin() async {
// this will run Dropbox app if possible, if not it will run authorization using a web browser.
await Dropbox.authorizePKCE();
}
Future getCredentials() async {
credentials = await Dropbox.getCredentials();
}
Future loginWithCredentials() async {
await Dropbox.authorizeWithCredentials(credentials);
}
Future testLogout() async {
// unlink removes authorization
await Dropbox.unlink();
}
// List / Upload / Download
Future testListFolder() async {
final result = await Dropbox.listFolder(''); // list root folder
print(result);
final url = await Dropbox.getTemporaryLink('/file.txt');
print(url);
}
Future testUpload() async {
final filepath = '/path/to/local/file.txt';
final result = await Dropbox.upload(filepath, '/file.txt', (uploaded, total) {
print('progress $uploaded / $total');
});
}
Future testDownload() async {
final filepath = '/path/to/local/file.txt';
