AppAuthWebView Android
Using AppAuth-Android with webview .
Installation
Add the library to your dependencies
compile 'com.github.hadiidbouk:AppAuthWebView-Android:1.1.4'
Also add this in your build.gradle (app)
android {
...
defaultConfig {
....
manifestPlaceholders = [
'appAuthRedirectScheme': ''
]
}
}
And in the project build.gradle
repositories {
..
maven {
url 'https://jitpack.io'
}
}
}
- Create your layouts
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="@+id/WebView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<FrameLayout
android:id="@+id/LoadingLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/holo_green_dark">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:text="Loading .."
android:textSize="30sp"
android:layout_gravity="center"
android:gravity="center"
/>
</FrameLayout>
<FrameLayout
android:id="@+id/ErrorLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/holo_red_dark"
>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Error"
android:textColor="#FFF"
android:textSize="30sp"
android:layout_gravity="center"
android:gravity="center"
/>
</FrameLayout>
</RelativeLayout>- Error Layout will be visible when there is a error received in webview .
- Loading Layout will be visible when waiting the page to be loaded.
- Create your AppAuthWebViewData
AppAuthWebViewData data = new AppAuthWebViewData();
data.setClientId(");
data.setAuthorizationEndpointUri("");
data.setClientSecret("");
data.setDiscoveryUri("n");
data.setRedirectLoginUri("");
data.setRedirectLogoutUri("");
data.setScope("");
data.setTokenEndpointUri("");
data.setRegistrationEndpointUri("");
data.setResponseType("");
data.setGenerateCodeVerifier(false);
- Implement IAppAuthWebViewListener
public class MainActivity extends Activity implements IAppAuthWebViewListener {
.....
@Override public void onUserAuthorize(AuthState authState) {
Toast.makeText(this, "Token : " + authState.getIdToken(), Toast.LENGTH_SHORT).show();
finish();
}
@Override public void showConnectionErrorLayout() {
mErrorLayout.setVisibility(View.VISIBLE);
}
@Override public void hideConnectionErrorLayout() {
mErrorLayout.setVisibility(View.INVISIBLE);
}
@Override public void showLoadingLayout() {
mLoadingLayout.setVisibility(View.VISIBLE);
}
@Override public void hideLoadingLayout() {
mLoadingLayout.setVisibility(View.INVISIBLE);
}
}
- Perform Login Request
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
....
AppAuthWebView appAuthWebView = new AppAuthWebView
.Builder()
.webView(webView)
.authData(data)
.listener(this)
.build();
appAuthWebView.performLoginRequest();
}
Working with tokens and refresh token
To access the id token or the access token you can simply call the static method AppAuthWebView.getAuthState(Context context) to get the authstate object (already saved in shared preferences) and then access what you want in this object.
To Perform a refresh token request you can simply call the static method AppAuthWebView.peroformRefreshTokenRequest(final Context context, AuthState authState, AppAuthWebViewData data) and if the request success the AuthState will be updated in the shared preferences.
If you are using a service in another process
If you want to get the access token from this service you can do the following :
- Create your class extends BroadcastReceiver ( example in Kotlin ) :
override fun onReceive(context: Context?, intent: Intent?) {
if(intent!!.action.equals(AppAuthWebView.BROADCAST_RECEIVER_ACTION)) {
val authState : String = intent.getStringExtra(AppAuthWebView.AUTH_STATE_JSON)
AppAuthWebView.updateAuthState(context,authState)
}
}
- Register to the broadcast by adding this to your manifest :
<receiver android:name=".MyBroadcastReceiver">
<intent-filter>
<action android:name="com.hadiidbouk.AppAuthWebView.AccessTokenAction"/>
</intent-filter>
</receiver>
