我已下载Android Rich Push Notification示例代码。我做了必要的更改，这些更改已在示例教程中进行了描述。

我没有对MainActivity.java文件进行任何更改。 这是MainActivity文件：
public class MainActivity extends ActionBarActivity implements
ActionBar.OnNavigationListener {
ArrayAdapter<String> navAdapter;
RichPushUser user;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.main_activity);
this.configureActionBar();
this.user = UAirship.shared().getRichPushManager().getRichPushUser();
}
@Override
protected void onNewIntent(Intent intent) {
setIntent(intent);
}
@Override
protected void onStart() {
super.onStart();
// Handle any Google Play services errors
if (PlayServicesUtils.isGooglePlayStoreAvailable()) {
PlayServicesUtils.handleAnyPlayServicesError(this);
}
// Activity instrumentation for analytic tracking
Analytics.activityStarted(this);
}
@Override
protected void onStop() {
super.onStop();
// Activity instrumentation for analytic tracking
Analytics.activityStopped(this);
}
@Override
protected void onResume() {
super.onResume();
setNavigationToMainActivity();
// Show a message dialog if the pending message id is not null
String pendingMessageId = getIntent().getStringExtra(RichPushApplication.EXTRA_OPEN_MESSAGE_ID);
if (!UAStringUtil.isEmpty(pendingMessageId)) {
getIntent().removeExtra(RichPushApplication.EXTRA_OPEN_MESSAGE_ID);
showRichPushMessage(pendingMessageId);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
this.getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.preferences:
this.startActivity(new Intent(this, PushPreferencesActivity.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
@Override
public boolean onNavigationItemSelected(int itemPosition, long itemId) {
String navName = this.navAdapter.getItem(itemPosition);
if (RichPushApplication.HOME_ACTIVITY.equals(navName)) {
// do nothing, we're here
} else if (RichPushApplication.INBOX_ACTIVITY.equals(navName)) {
Intent intent = new Intent(this, InboxActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
this.startActivity(intent);
}
return true;
}
/**
* Displays the rich push message in a RichPushMessageDialogFragment
* @param messageId The specified message id
*/
private void showRichPushMessage(String messageId) {
RichPushMessageDialogFragment message = RichPushMessageDialogFragment.newInstance(messageId);
message.show(this.getSupportFragmentManager(), "message");
}
/**
* Configures the action bar to have a navigation list of
* 'Home' and 'Inbox'
*/
private void configureActionBar() {
ActionBar actionBar = this.getSupportActionBar();
actionBar.setDisplayUseLogoEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
this.navAdapter = new ArrayAdapter<String>(this, android.support.v7.appcompat.R.layout.support_simple_spinner_dropdown_item,
RichPushApplication.navList);
actionBar.setListNavigationCallbacks(this.navAdapter, this);
}
/**
* Sets the action bar navigation to show 'Home'
*/
private void setNavigationToMainActivity() {
int position = this.navAdapter.getPosition("Home");
getSupportActionBar().setSelectedNavigationItem(position);
}
}
运行示例代码时，我遇到了这个问题：
java.lang.NoClassDefFoundError: com.urbanairship.R$string
at com.urbanairship.push.NotificationActionButtonGroupFactory.createUrbanAirshipGroups(NotificationActionButtonGroupFactory.java:40)
at com.urbanairship.push.PushManager.<init>(PushManager.java:198)
at com.urbanairship.push.PushManager.<init>(PushManager.java:186)
请帮我解决问题。 提前谢谢。
答案 0 :(得分：2)
如果您使用的是Eclipse或Android Studio，我无法直接告诉您的问题，但我在Android Studio中遇到了这个问题。
我在我的项目的libs文件夹中包含了urbanairship-lib-x.x.x.jar文件，但这产生了与您遇到的相同的错误，即使编译很好。
我做了什么：
repositories {
mavenCentral()
flatDir {
dirs 'aars'
}
}
...
dependencies {
compile 'com.google.android.gms:play-services:5.0.89'
compile 'com.android.support:support-v4:20.+'
compile 'com.urbanairship:urbanairship-lib:+@aar'
}
不幸的是，我对使用Eclipse的任何解决方案都不熟悉。
