Question

I want to start multiple instance of the same Activity class from a Service. The reason I’m doing this, is because I have a Service that runs a “scan” daily, and if it finds any malfunctions it should display a popup for each malfunction.

The Activity that I’m starting is more like a Dialog, has a Dialog theme to display info about the malfunction.

Manfiest:

<activity
   android:name=".ui.dialogs.MalfunctionActivity"
   android:theme="@style/MyDialog"
   android:launchMode="standard">

Intent to start the activity from Service:

    Intent displayMalf=new Intent(this, MalfunctionActivity.class);
    displayMalf.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(displayMalf);

PROBLEM: to start the Activity from a Service I need the FLAG_ACTIVITY_NEW_TASK which somehow cancels the launchMode="standard" from the manifest, and gives me just one Activity even if I try to start multiple diffrent instances.
Is there anyway in which I can achieve this?

Answer 1

It was so simple. There is the flag FLAG_ACTIVITY_MULTIPLE_TASK which according to the documentation :

Used in conjunction with FLAG_ACTIVITY_NEW_TASK to disable the behavior of bringing an existing task to the foreground. When set, a new task is always started to host the Activity for the Intent, regardless of whether there is already an existing task running the same thing.

Was exactly what I need. Thanks and sorry for answering on my question. It is not a habit. 🙂
