Evernote API version 1.25
This SDK wraps the Evernote Cloud API and provides OAuth authentication functionality. The SDK is provided as an Android Library project that can be included in your application with Gradle.
In order to use the code in this SDK, you need to obtain an API key from https://dev.evernote.com/doc/. You'll also find full API documentation on that page.
In order to run the demo code, you need a user account on the sandbox service where you will do your development. Sign up for an account at https://sandbox.evernote.com/Registration.action
The instructions below assume you have the latest Android SDK.
Add the library as a dependency in your build.gradle file.
dependencies {
compile 'com.evernote:android-sdk:2.0.0-RC4'
}Add Sonatype's snapshot repository in your build script.
maven {
url "https://oss.sonatype.org/content/repositories/snapshots"
}Add the snapshot depdendency.
dependencies {
compile 'com.evernote:android-sdk:2.0.0-SNAPSHOT'
}The demo application 'Evernote SDK Demo' demonstrates how to use the Evernote SDK for Android to authentication to the Evernote service using OAuth, then access the user's Evernote account. The demo code provides multiple activities that show notebook listing, note creation, and resource creation in two scenarios: A plain text note creator and an image saver.
To build and run the demo project from Android Studio:
- Open Android Studio
- Choose Import Project (Eclipse ADT, Gradle, etc.)
- Select the SDK root directory (the directory containing this README) and click OK
- Add your Evernote API consumer key and secret (see below)
You have two different options to add your consumer key and secret.
- Open the folder
~/.gradlein your user's home directory. - Open or create a file called
gradle.properties - Add a line
EVERNOTE_CONSUMER_KEY=Your Consumer Key - Add a line
EVERNOTE_CONSUMER_SECRET=Your Consumer Secret
- Open the class
com.evernote.android.demo.DemoApp.java - At the top of
DemoApp.java, fill in your Evernote API consumer key and secret.
The SDK's OAuth functionality is implemented as an Android Activity that must be declared in your app's AndroidManifest.xml.
Starting with Android Gradle plugin version 1.0.0 the necessary activities are merged in your app's AndroidManifest.xml file and you don't need to do anything. Otherwise simply copy and paste the following snippet into your AndroidManifest.xml within the application section:
<activity android:name="com.evernote.client.android.EvernoteOAuthActivity" />
<activity android:name="com.evernote.client.android.login.EvernoteLoginActivity"/>Define your app credentials (key, secret, and host). See http://dev.evernote.com/documentation/cloud/
private static final String CONSUMER_KEY = "Your consumer key";
private static final String CONSUMER_SECRET = "Your consumer secret";
private static final EvernoteSession.EvernoteService EVERNOTE_SERVICE = EvernoteSession.EvernoteService.SANDBOX;When your app starts, initialize the EvernoteSession singleton that has all of the information that is needed to authenticate to Evernote. The EvernoteSession instance of saved statically and does not need to be passed between activities. The better option is to build the instance in your onCreate() of the Application object or your parent Activity object.
mEvernoteSession = new EvernoteSession.Builder(this)
.setEvernoteService(EVERNOTE_SERVICE)
.setSupportAppLinkedNotebooks(SUPPORT_APP_LINKED_NOTEBOOKS)
.build(consumerKey, consumerSecret)
.asSingleton();In our demo app, we have a "Login" button that initiates the authentication process. You might choose to do something similar, or you might simply initiate authentication the first time that the user tries to access Evernote-related functionality.
The recommended approach is to use FragmentActivitys. Then the authentication process opens a dialog and no extra Activity. But normal Activitys are supported as well.
mEvernoteSession.authenticate(this);The Activity that completes the OAuth authentication automatically determines if the User is on the Evernote service or the Yinxiang service and configures the end points automatically.
If you want to test if bootstrapping works within your app, you can either change the device's language to Chinese or you can set a specific Locale object in the session builder, e.g. new EvernoteSession.Builder(this).setLocale(Locale.SIMPLIFIED_CHINESE). If the SDK can't decide which server to use, then the user has the option to change the Evernote service while authenticating.
If you use a FragmentActivity, you should implement the EvernoteLoginFragment.ResultCallback interface.
public class MyActivity extends Activity implements EvernoteLoginFragment.ResultCallback {
// ...
@Override
public void onLoginFinished(boolean successful) {
// handle result
}
} If you use a normal Activity, you should override onActivityResult.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case EvernoteSession.REQUEST_CODE_LOGIN:
if (resultCode == Activity.RESULT_OK) {
// handle success
} else {
// handle failure
}
break;
default:
super.onActivityResult(requestCode, resultCode, data);
break;
}
}Calling EvernoteSession.getEvernoteClientFactory() will give you access to async wrappers around NoteStore.Client or UserStore.Client. Browse the API JavaDocs at http://dev.evernote.com/documentation/reference/javadoc/
The EvernoteClientFactory also creates multiple helper classes, e.g. EvernoteHtmlHelper to download a note as HTML.
Create an EvernoteNoteStoreClient to access primary methods for personal note data
EvernoteSession.getInstance().getEvernoteClientFactory().getNoteStoreClient();Create an EvernoteUserStoreClient to access User related methods
EvernoteSession.getInstance().getEvernoteClientFactory().getUserStoreClient();Create an EvernoteBusinessNotebookHelper to access Business Notebooks
EvernoteSession.getInstance().getEvernoteClientFactory().getBusinessNotebookHelper();Create an EvernoteLinkedNotebookHelper to access shared notebooks
EvernoteSession.getInstance().getEvernoteClientFactory().getLinkedNotebookHelper(linkedNotebook);if (!EvernoteSession.getInstance().isLoggedIn()) {
return;
}
EvernoteNoteStoreClient noteStoreClient = EvernoteSession.getInstance().getEvernoteClientFactory().getNoteStoreClient();
noteStoreClient.listNotebooksAsync(new EvernoteCallback<List<Notebook>>() {
@Override
public void onSuccess(List<Notebook> result) {
List<String> namesList = new ArrayList<>(result.size());
for (Notebook notebook : result) {
namesList.add(notebook.getName());
}
String notebookNames = TextUtils.join(", ", namesList);
Toast.makeText(getApplicationContext(), notebookNames + " notebooks have been retrieved", Toast.LENGTH_LONG).show();
}
@Override
public void onException(Exception exception) {
Log.e(LOGTAG, "Error retrieving notebooks", exception);
}
});if (!EvernoteSession.getInstance().isLoggedIn()) {
return;
}
EvernoteNoteStoreClient noteStoreClient = EvernoteSession.getInstance().getEvernoteClientFactory().getNoteStoreClient();
Note note = new Note();
note.setTitle("My title");
note.setContent(EvernoteUtil.NOTE_PREFIX + "My content" + EvernoteUtil.NOTE_SUFFIX);
noteStoreClient.createNoteAsync(note, new EvernoteCallback<Note>() {
@Override
public void onSuccess(Note result) {
Toast.makeText(getApplicationContext(), result.getTitle() + " has been created", Toast.LENGTH_LONG).show();
}
@Override
public void onException(Exception exception) {
Log.e(LOGTAG, "Error creating note", exception);
}
});- Check if user is member of a business
- Create
EvernoteBusinessNotebookHelper - Call synchronous methods from a background thread or call async methods from UI thread
This note store is not long lived, the Business authentication token expires frequently and is refreshed if needed in the getBusinessNotebookHelper() method.
Example using the synchronous business methods inside a background thread to create a note in a business account
new Thread() {
@Override
public void run() {
try {
if (!EvernoteSession.getInstance().getEvernoteClientFactory().getUserStoreClient().isBusinessUser()) {
Log.d(LOGTAG, "Not a business User");
return;
}
EvernoteBusinessNotebookHelper businessNotebookHelper = EvernoteSession.getInstance().getEvernoteClientFactory().getBusinessNotebookHelper();
List<LinkedNotebook> businessNotebooks = businessNotebookHelper.listBusinessNotebooks(EvernoteSession.getInstance());
if (businessNotebooks.isEmpty()) {
Log.d(LOGTAG, "No business notebooks found");
}
LinkedNotebook linkedNotebook = businessNotebooks.get(0);
Note note = new Note();
note.setTitle("My title");
note.setContent(EvernoteUtil.NOTE_PREFIX + "My content" + EvernoteUtil.NOTE_SUFFIX);
EvernoteLinkedNotebookHelper linkedNotebookHelper = EvernoteSession.getInstance().getEvernoteClientFactory().getLinkedNotebookHelper(linkedNotebook);
final Note createdNote = linkedNotebookHelper.createNoteInLinkedNotebook(note);
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), createdNote.getTitle() + " has been created.", Toast.LENGTH_LONG).show();
}
});
} catch (TException | EDAMUserException | EDAMSystemException | EDAMNotFoundException e) {
e.printStackTrace();
