我有一个应用程序,我想在其中构建2个不同的流程：
> 1.a应用程序对任何活动开放
> 1.b App show是一个警告框,用户可以选择转到有关通知的活动或保持当前活动.
> 2.a应用程序正在后台运行
> 2.b通知栏中的通知,启动有关通知的活动.
我目前有流量2工作,但无法找到如何让流量1工作.这是一些代码：
在GcmIntentService中：
@Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
// The getMessageType() intent parameter must be the intent you received
// in your BroadcastReceiver.
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) { // has effect of unparcelling Bundle
/*
* Filter messages based on message type. Since it is likely that GCM will be
* extended in the future with new message types,just ignore any message types you're
* not interested in,or that you don't recognize.
*/
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
Log.e("GCM","Send error: " + extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
Log.e("GCM","Deleted messages on server: " + extras.toString());
// If it's a regular GCM message,do some work.
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
Log.i(TAG,"Completed work @ " + SystemClock.elapsedRealtime());
// Post notification of received message.
sendNotification(extras);
Log.i(TAG,"Received: " + extras.toString());
}
}
// Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
// Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(Bundle extras) {
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
String message = extras.getString("message");
Intent openIntent = new Intent(this,HomeActivity.class);
if (extras != null) {
if (extras.containsKey("tipid")) {
openIntent.putExtra("tipid",extras.getString("tipid"));
} else if (extras.containsKey("discussionid")) {
openIntent.putExtra("discussionid",extras.getString("discussionid"));
}
}
PendingIntent contentIntent = PendingIntent.getActivity(this,openIntent,PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("StadseBoeren")
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(message))
.setContentText(message);
mBuilder.setContentIntent(contentIntent)
.setAutoCancel(true);
mNotificationManager.notify(NOTIFICATION_ID,mBuilder.build());
}
GcmBroadcastReceiver
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context,Intent intent) {
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),GcmIntentService.class.getName());
// Start the service,keeping the device awake while it is launching.
startWakefulService(context,(intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
HomeActivity onCreate：
Bundle extras = intent.getExtras();
if (extras != null) {
if (extras.containsKey("tipid")) {
pendingObjectId = extras.getString("tipid");
modelFlag = ModelFlag.TIP;
} else if (extras.containsKey("discussionid")) {
pendingObjectId = extras.getString("discussionid");
modelFlag = ModelFlag.DISCUSSION;
}
}
解决方法
使类扩展Application并实现ActivityLifecycleCallbacks
并根据暂停和onResume更新公共布尔值.
并根据暂停和onResume更新公共布尔值.
在收到push时检查此布尔值并执行您的要求.
希望对你有帮助
public class TestApplication extends Application implements ActivityLifecycleCallbacks{
boolean applicationOnPause = false;
@Override
public void onCreate() {
super.onCreate();
registerActivityLifecycleCallbacks(this);
}
@Override
public void onActivityCreated(Activity arg0,Bundle arg1) {
Log.e("","onActivityCreated");
}
@Override
public void onActivityDestroyed(Activity activity) {
Log.e("","onActivityDestroyed ");
}
@Override
public void onActivityPaused(Activity activity) {
applicationOnPause = true;
Log.e("","onActivityPaused "+activity.getClass());
}
@Override
public void onActivityResumed(Activity activity) {
applicationOnPause = false;
Log.e("","onActivityResumed "+activity.getClass());
}
@Override
public void onActivitySaveInstanceState(Activity activity,Bundle outState) {
Log.e("","onActivitySaveInstanceState");
}
@Override
public void onActivityStarted(Activity activity) {
Log.e("","onActivityStarted");
}
@Override
public void onActivityStopped(Activity activity) {
Log.e("","onActivityStopped");
}
}
