开始第二项活动，但失败回到第一项活动

Question

Assume that I completely quite my application. (no more activity stack)

However, the notification arrive and user will be navigate to second activity when click

The question is how can I make an second activity back to first activity (lancher) and then exit

instead of exit directly if press back button (because it doesn't have any stack)!?

NOTIFICATION WHICH NAVIGATE TO SECOND ACT.

 NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_stat_social_person)
                        .setContentTitle("AIR° TRACKING MODE!")
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(msg))
                        .setContentText(msg)
                        .setLights(Color.BLUE, 500, 500)
                        .setDefaults(Notification.DEFAULT_ALL)
                        .setOngoing(true);

        PendingIntent contentIntent = PendingIntent.getActivity(
                this,
                0,
                new Intent(this, Activity_Second.class).addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT),
                PendingIntent.FLAG_UPDATE_CURRENT);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(GM.NOTIFICATION_TRACKING_MODE, mBuilder.build());
    }

Answer 1

Try this..

You can add that in onBackPressed() Override method from Activity_Second.class to Activity_First.class

@Override
public void onBackPressed() {
    Intent ide = new Intent(this, Activity_First.class);
    ide.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(ide);

    finish();
}

Answer 2

TaskStackBuilder is the best choice, I think so...

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);

    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(Activity_One.class);
    stackBuilder.addNextIntent(resultIntent);

and in the Manifest:

work for API < 16

 <activity android:name=".Activity_Second">
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".Activity_One" />
    </activity>

for API > 16

 <activity android:name=".Activity_Second"
        android:parentActivityName=".Activity_One" />

sorry. when use TaskStackBuilder, remember to edit you PendingIntent like this:

     PendingIntent contentIntent =
        stackBuilder.getPendingIntent(
            0,
            PendingIntent.FLAG_UPDATE_CURRENT
        );

Answer 4

Use this code

@Override
public void onBackPressed() {
    Intent ide = new Intent(this, Activity_First.class);
    ide.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
    startActivity(ide);
    finish();
}

TaskStackBuilder is the most appropriate for complex activity Easy to manage... if you know how !

Navigate Code from Notification & add proper back stack

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_stat_social_person)
                    .setContentTitle("AIR° TRACKING MODE!")
                    .setStyle(new NotificationCompat.BigTextStyle()
                            .bigText(msg))
                    .setContentText(msg)
                    .setLights(Color.BLUE, 500, 500)
                    .setDefaults(Notification.DEFAULT_ALL)
                    .setOngoing(true);

    PendingIntent contentIntent = TaskStackBuilder.create(this)
            //addParentStack is destination class not its parent class
            //it will refer parent class from what you define in XML
            .addParentStack(Activity_TrackingMode.class)
            //and provide intent for destination class
            .addNextIntent(new Intent(this, Activity_TrackingMode.class))
            .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(GM.NOTIFICATION_TRACKING_MODE, mBuilder.build());

Example of XML in AndroidManifest

    <activity android:name=".Activity_TrackingMode"
              android:label="@string/app_name"
              android:screenOrientation="portrait"
              android:parentActivityName=".Activity_Screen1">
        <!-- Parent activity meta-data to support 4.0 and lower -->
        <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".Activity_Screen1" />
        <intent-filter>
            <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>
    </activity>

PS. > import android.support.v4.app.TaskStackBuilder; //for support API below 16
