如何获得registrationId?
我总是会收到ACCOUNT_MISSING错误
主要 Activity
package com.example.gcm;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.app.NavUtils;
import com.google.android.gcm.GCMRegistrar;
public class MainActivity extends Activity {
private static final String SENDER_ID = "45552950387";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
GCMRegistrar.register(this, SENDER_ID);
Log.d("show", "Already registered1"+regId);
} else {
Log.d("show", "Already registered");
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
GCMIntentService
package com.example.gcm;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.google.android.gcm.GCMBaseIntentService;
public class GCMIntentService extends GCMBaseIntentService {
private static final String TAG = "GCMIntentService";
public GCMIntentService() {
super("45552950387");
}
@Override
protected void onRegistered(Context context, String registrationId) {
Log.i(TAG, "Device registered: regId = " + registrationId);
}
@Override
protected void onUnregistered(Context context, String registrationId) {
Log.i(TAG, "Device unregistered");
}
@Override
protected void onMessage(Context context, Intent intent) {
Log.i(TAG, "Received message");
String a = intent.getStringExtra("A");
generateNotification(context, a);
}
@Override
protected void onDeletedMessages(Context context, int total) {
Log.i(TAG, "Received deleted messages notification");
}
@Override
public void onError(Context context, String errorId) {
Log.i(TAG, "Received error: " + errorId);
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
Log.i(TAG, "Received recoverable error: " + errorId);
return super.onRecoverableError(context, errorId);
}
private void generateNotification(Context context, String message) {
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.icon = R.drawable.ic_launcher;
notification.tickerText = "notification on status bar.";
notification.defaults = Notification.DEFAULT_ALL;
notification.setLatestEventInfo(context, "Title", message, null);
notificationManager.notify(0, notification);
}
}

我确定发件人ID是正确的,并且还在项目类路径中导入了gcm.jar
最佳答案
手机上没有Google帐户时发生ACCOUNT_MISSING错误。
