[英]Android back-stack not being created from Notification PendingIntent
[英]PendingIntent not being launched from Notification
我已經嘗試了大約20種不同的StackOverflow答案,但沒有任何一項正在起作用!
我只想從我提出的通知中發起一個活動。 沒用 它什么也沒做,如果我進入主屏幕並單擊它,它甚至不會啟動該應用程序。
從一開始我就添加了很多東西,所以對所有可能不需要的東西感到抱歉。 我只是一直在尋找SO並嘗試解決方案。
private void sendNotification(String msg, String cont, String title) {
mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
// this.getSystemService(Context.NOTIFICATION_SERVICE);
Log.d("msg",msg);
int requestID = (int) System.currentTimeMillis();
Intent notificationIntent = new Intent(getApplicationContext(), WalkerRequest.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
Log.d("Intent","setting content intent");
PendingIntent contentIntent = PendingIntent.getActivity(this, requestID, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT
| PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.paw_icon)
.setContentTitle(title)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(cont))
.setContentText(cont);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
這是完整的課程,直接來自Google。
public class GcmIntentService extends IntentService {
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
public GcmIntentService() {
super("GcmIntentService");
}
public static final String TAG = "GCM Demo";
@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)) {
sendNotification("Send error: ", extras.toString(), "Nada");
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification("Deleted messages on server: ", extras.toString(), "nada");
// If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
// This loop represents the service doing some work.
for (int i = 0; i < 5; i++) {
Log.i(TAG, "Working... " + (i + 1)
+ "/5 @ " + SystemClock.elapsedRealtime());
try {
Thread.sleep(500);
} catch (InterruptedException e) {
}
}
String cont = intent.getExtras().getString("message");
String title = intent.getExtras().getString("title");
Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
// Post notification of received message.
sendNotification("Received: ", cont, title);
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(String msg, String cont, String title) {
mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
// this.getSystemService(Context.NOTIFICATION_SERVICE);
Log.d("msg",msg);
int requestID = (int) System.currentTimeMillis();
Intent notificationIntent = new Intent(getApplicationContext(), WalkerRequest.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
Log.d("Intent","setting content intent");
PendingIntent contentIntent = PendingIntent.getActivity(getBaseContext(), requestID, notificationIntent, PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.paw_icon)
.setContentTitle(title)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(cont))
.setContentText(cont);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
這是收貨
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);
}
}
當您的應用程序不處於活動狀態時, getApplicationContext()
將不可用,因此最好使用該服務的context
。
我的建議是,通過這些方法盡可能地追溯到接收到推送通知意圖的地方,並更改傳遞給onReceive()
方法的任何Context,然后將其替換為帶有context
getApplicationContext()
然后可以在方法中使用context參數。
試試這個: public void createNotification() { try { Intent pnIntent = new Intent(this, newActivity.class); pnIntent.putExtra("notificationId", NOTIFICATION_ID); PendingIntent pendingIntent = PendingIntent.getActivity(this, 01, pnIntent, Intent.FLAG_ACTIVITY_CLEAR_TASK); NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext()); builder.setContentTitle(getString(R.string.app_name)); builder.setContentText(getString(R.string.running)); builder.setContentIntent(pendingIntent); builder.setSmallIcon(R.drawable.ic_stat_permanent_notification); builder.setAutoCancel(false); builder.setOngoing(true); builder.setPriority(1); Notification notification = builder.build(); final NotificationManager notificationManger = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManger.notify(permanentNotificationId, notification); } catch (Exception e) { Log.e("UnityApplication", "Error while creating notification", e); } }
public void createNotification() { try { Intent pnIntent = new Intent(this, newActivity.class); pnIntent.putExtra("notificationId", NOTIFICATION_ID); PendingIntent pendingIntent = PendingIntent.getActivity(this, 01, pnIntent, Intent.FLAG_ACTIVITY_CLEAR_TASK); NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext()); builder.setContentTitle(getString(R.string.app_name)); builder.setContentText(getString(R.string.running)); builder.setContentIntent(pendingIntent); builder.setSmallIcon(R.drawable.ic_stat_permanent_notification); builder.setAutoCancel(false); builder.setOngoing(true); builder.setPriority(1); Notification notification = builder.build(); final NotificationManager notificationManger = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManger.notify(permanentNotificationId, notification); } catch (Exception e) { Log.e("UnityApplication", "Error while creating notification", e); } }
