Integration with Existing Apps

With a few steps, you can add messenger based features, screens, views, etc.


For the correct project compilation follow the instructions for building apps from the Getting Started section to configure your development environment.


library supports API level >= 16 (Android 4.1)

We use Multidex to avoid the 64K methods limit. So, you need to implement it in your project: set multiDexEnabled to true in your module-level build.gradle file and add the multidex library as a dependency:

android {
    defaultConfig {
      minSdkVersion 15
      targetSdkVersion 26
      multiDexEnabled true

dependencies {
       compile ''

If you do override the Application class, change it to extend MultiDexApplication (if possible) as follows:

public class MyApplication extends MultiDexApplication

or override the attachBaseContext() method instead and call MultiDex.install(this) to enable multidex:

public class MyApplication extends SomeOtherApplication {
 protected void attachBaseContext(Context base) {

Possible issues

  • No resource found that matches the given name

The problem usually appears when different versions of the same library present within the application. In this case, different versions of support library.

If you don’t see them in your gradle file, then they are probably added as dependencies. Run the following in terminal, to see the dependencies for each library:

./gradlew app:dependencies

Then, find the libraries that use old versions of appcompat and update / remove, whatever suits you.

  • Attribute value=(@string/provider_authority) from AndroidManifest.xml: is also present at [im.dlg:android-sdk:version_name] AndroidManifest.xml

If you implemented any of providers, add tools:replace="android:authorities" to <provider> element at AndroidManifest.xml to override string values.

Adding Dialog to your app

First, initialize messenger by executing in onCreate() in your Application class DialogSDK.get().initilize(application) .

Simple example:

DialogSDK dialogSDK = DialogSDK.get();
dialogSDK.setEndpoints("your custom endpoint");

You can find more information about configuration possibilities in basic application configuration section

Entry point activity can be started with method from DialogSDK class:

DialogSDK.get().startMessagingApp(activity, token)

You need to specify token for end-to-end authorization as a second parameter.

To check messenger login state use messenger().isLoggedIn .

There are 3 activity screens for each section:

Screen with user private and group dialogs
Screen with list of contacts imported from device address book
Screen with user’s calls history
