这是我的GCMBaseIntentService Java文件。
public class GCMIntentService extends GCMBaseIntentService {
private static final String TAG = "GCMIntentService";
public GCMIntentService() {
super(SENDER_ID);
}
@Override
protected void onRegistered(Context context, String registrationId) {
Log.i(TAG, "Device registered: regId = " + registrationId);
displayMessage(context, "Your device registred with GCM");
Log.d("GCMRegister", "GCMRegisterSucess");
}
@Override
protected void onUnregistered(Context context, String registrationId) {
Log.i(TAG, "Device unregistered");
displayMessage(context, getString(R.string.gcm_unregistered));
}
@Override
protected void onMessage(Context context, Intent intent) {
Log.d(TAG, "Received message");
String message = intent.getExtras().getString("price");
displayMessage(context, message);
// notifies user
generateNotification(context, message);
}
@Override
protected void onDeletedMessages(Context context, int total) {
Log.i(TAG, "Received deleted messages notification");
String message = getString(R.string.gcm_deleted, total);
displayMessage(context, message);
// notifies user
generateNotification(context, message);
}
@Override
public void onError(Context context, String errorId) {
Log.i(TAG, "Received error: " + errorId);
displayMessage(context, getString(R.string.gcm_error, errorId));
}
@Override
protected boolean onRecoverableError(Context context, String errorId) {
// log message
Log.i(TAG, "Received recoverable error: " + errorId);
displayMessage(context, getString(R.string.gcm_recoverable_error,
errorId));
return super.onRecoverableError(context, errorId);
}
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, MainActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent =
PendingIntent.getActivity(context, 0, notificationIntent, 0);
// notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}
}
构建。gradle类
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.1"
defaultConfig {
applicationId "com.bindaspunch.my.gcmdemo"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile files('libs/gcm.jar')
}
我没有得到通知，错误显示在这行
notificationManager.notify(0, notification);
在generateNotification方法..
但是如果我使用
Notification notification = new Notification.Builder(context)
.setContentText(message)
.setSmallIcon(icon)
.setWhen(when)
.build();
代替这一行。
Notification notification = new Notification(icon, message, when);
Notification get with a Icon，但没有得到notificationIntent，也没有打开MainActivity类。
Intent notificationIntent = new Intent(context, MainActivity.class);
这是我的manifest类

i dont know very much about gcm notification service, so if you have any kind of solution for this issue, jst help me out of it.
i know my english is poor so Sorry for my english.. and Thanks in advance..
尝试取消注释:
notification.setLatestEventInfo(context, title, message, intent);
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, MainActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(0, notification);
}
或者这样试试:
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
String title = context.getString(R.string.app_name);
Intent notificationIntent = new Intent(context, MainActivity.class);
// set intent so it does not start a new activity
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setContentTitle(title);
builder.setContentText(message)
builder.setSmallIcon(icon);
builder.setContentIntent(intent);
builder.setWhen(when)
builder.setDefaults(Notification.DEFAULT_LIGHTS| Notification.DEFAULT_VIBRATE| Notification.DEFAULT_SOUND);
builder.setAutoCancel(true);
notificationManager.notify(0, builder.build());
}
