Android - difference between show Alert dialog on service directly and by activity

Since I read showing Alert Dialog on Service may damage on other program , I want to know is there difference between showing Alert Dialog directly like this:
AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.show();
And showing through specific activity?
I want something like communication application's popup (e.g. Line Messenger,..)
which of ways do you recommend?
You can start a Transparent activity from your service which shows the dialog within itself.
First create the "transparent" activity and set its theme like this in the Manifest
<activity android:name=".MyPopUpActivity" android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen"/>
Set the background of this activity to a transparent colour of your choice.
From your service, start this activity. Make sure to pass whatever data needed to show the Dialog.
Once the activity is launched, use a DialogFragment to show the dialog. Using DialogFragment is the recommended way to display dialogs in android.
I haven't tested this approach myself but I am pretty sure it will do the trick for you.
Let me know if it works for you

Already have this question in stackoverflow. I know some code are missed. what are the steps. pls help me. Advanced thanks,
Android activity can create as dialog and. activity can run single screen only. multiple activity run on fragment only. you can't make popup window as a activity.
Set below property in manifest for the activity which you want to be open as dialog:
<activity android:theme="#android:style/Theme.Dialog" />

You just also finish activity and than open new activity. New Activity' s style to android:theme="#style/Theme.Translucent" in your manifest file. And than set a view maybe empty textview, open dialog.
you can acheive this by using custom dialog
.in this give background color to black it will hide back activity
or you can acheive this by launching activity as dialog
Start activity as dialog i used this
<activity android:theme="#android:style/Theme.Dialog" />
now when i startActivity(in) it displays like dialog.
instead of showing dialog in activity you can directly use dialog theme in manifest file for activity.and use that activity as a dialog box.

AlertDialog buttons always close the dialog once clicked

I'm using an AlertDialog with 2 buttons (one positive, one negative).
I've set a handler for those buttons which doesn't mention dismiss. Indeed after clicking, I don't want the dialog to close. However, it seems that as soon as we click on a positive/negative button on an AlertDialog, it always get closed.
Is there a way to prevent the dialog from closing after clicking on any button ?
Thanks,
Vincent
Use custom layout for Dialog and you will be happy!
Use a custom dialog, not an AlertDialog.
You can also create a new Activity and assign it the theme dialog in your manifest with
<activity android:name="MyDialogActivity" android:theme="#android:style/Theme.Dialog" />
