Transparent Activity opening independently

I want to create a activity with transparent background that I can start by clicking on a Notification.

I created the notification and the activity with no problem, but now, I want to open this particular TransparentActivity independently i.e. without showing the other activities on the background.

I tried to put some flags on the intent:

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);

and on the AndroidManifest file, on my TransparentActivity tag, I put:

<activity

    android:name=".TransparentActivity"

    android:launchMode="singleTask"

    android:theme="@style/Theme.Transparent">

    <intent-filter>

        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />

    </intent-filter>

</activity>

It works as expected, but now I have two icons for my app, which is something I don't want.

Is there a way to make it work?

It did not work. Should I do something else other than adding this new flag?

To understand you situation, can you post screenshot of two icons ?

I don't have a screenshot right now (I can send it later) but Android will create one icon for every single activity with the intent filter "LAUNCHER" when installing the app.

You should remove the <intent-filter> for your TransparentActivity. You don't need that. Android creates an application icon for each and every Activity that has an <intent-filter> with ACTION=MAIN and CATEGORY=LAUNCHER.

Easiest way to do this is to change the taskAffinity for this Activity in the manifest. Add:

android:taskAffinity=""

to the <activity> declaration for this oneActivity`.

This one Activity will then be launched into a new task, and not into the task that runs the rest of your application.

I was using task affinity, but "singleTask" instead of "singleInstance". I read the tasks and back-stack documentation, and I was sure "singleTask" was the one I was looking for. Using "singleInstance" worked for me, thanks :D

I don't know why you edited my answer and added the word "singleInstance" to the taskAffinity declaration. This has nothing to do with launchMode and that edit certainly confused the matter. You set the taskAffiinity to an empty string and that means that the Activity has no affinity for any other activities, so it can run in any task. In reality it makes no difference that string you use, but using the string "singleInstance" could surely confuse people. I reedited my answer.

Looking at your original post, you are not using taskAffinity, you are using launchMode="singleTask".
