Ok I saw a lot of people just dismiss this question by saying

"it's reserved for OS component "

"it requires access to source"

Well I have access to the source and I can set any app or widget I want as a system app. So now how would I go about making my widget show its notification on the right side?

EDIT: ok ppl are going in the wrong direction so ill add come context here . . . look at ur phone . . . u see Wi-Fi signal and phone signal on the right side of the phone all the time right. I want my signal to be shown there aswell . . . along with the system signals . . I have a new hardware chip in the tablet my company is making and I have to display its signal strength constantly just like the phone signal. It is going to be integrated into the Android source of the tablet.

  • Are you talking about how to make an Android TABLET style status bar? – Robin Aug 21 '13 at 08:09
  • No . . . look at ur phone . . . u see wifi signal and phone signal on the right side of the phone all the time right.

  • so many views and no answer . . . can someone up vote the question so that people feel the need to answer it ?? or how does the bounty thing work ?? – Prince Champappilly Dec 10 '13 at 06:51
  • Hey if you've figure this out please share a snippet – Zen May 05 '14 at 01:22
  • Google Japanese Input displays A or あ icon on the right side. It is not a system application, but just a normal application you can download from the Play Store. It worked both on a 4.4.2 Samsung device and on a 5.1.1 Nexus device. So there must be some kind of API. – Damn Vegetables May 21 '15 at 07:02

You might need to refer to the code of Android source code of phone status bar, at https://android.googlesource.com/platform/frameworks/base/+/android-4.3_r3.1/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java

And take a look at the methods like

addIcon
updateIcon
removeIcon

It is not easy task since you have to add lots of stuff by yourself.

  • @PrinceChampappilly any progress with this answer? vallathum nadakkumo? – Vishnudev K Jun 30 '14 at 13:16
  • @VishnudevK vallathum nadakuvo ennu chodicha . . .Yes this is the answer . . . But u need to add ur custom listener in the android framework. What I did was pull down the code for a dual sim phone and replace the 2nd sims signal notification with my custom notification . . that way I just needed to edit that instance across the code. I didn't complete the whole process . . . I was reassigned to another project half way through. – Prince Champappilly Jul 03 '14 at 08:42
  • I want to ask how did you answer this question? I mean did you studied whole android source code or you used a tool to search through the code? – VSB Aug 02 '16 at 17:39
  • @VSB Hi. Do you now know the answer to that question? – Edw590 May 03 '21 at 10:30

    @DADi590 it is a long time ago. Unfortunately, I could not check or remember. – VSB May 03 '21 at 12:13

You'll need to modify a few places:

framework/base/core/res/res/values/config.xml, add a slot in: <string-array name="config_statusBarIcons">

then frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBarPolicy.java:

mService.setIcon("<your slot name>", R.drawable.yourlogo, 0, null);
mService.setIconVisibility("<your slot name>", setVisible);

That's mostly it, I'm sure you can figure out the rest on your own with some trial and errors.

I have one easy idea ie:

In manifest declare android screen orientation as landscape and design like landscape for portrait mode so that ur app looks portrait in landscape mode.

  • Haha . . this works only when inside the app . . . I want this to work on a widget button press so that it'll be visible always even on the homepage . . . nice trick btw :P – Prince Champappilly Aug 21 '13 at 07:02
  • You'd need to modify the Android OS to some extent, but since Android is open source, that's not a problem. The problem is getting it installed on phones - if you've noticed, the only companies that have custom UIs are also phone manufacturers, so they can just ship their phones with it installed. – Ruban Aug 21 '13 at 09:27
  • I am manufacturing the tablet and I have already got my android source up and running on my tablet . . I just want to kno which part of the source I need to edit to add my signal bar to the notification part. – Prince Champappilly Aug 21 '13 at 13:07
  • That is why I tagged android-source , only people who have experience with editing android source can help me . . . ty for ur effort though :) – Prince Champappilly Aug 21 '13 at 13:08

  • This is not what he is looking for, he wants the icon in notification bar to be displayed on right side. – Sunil Mishra Aug 21 '13 at 06:22
  • Notification notification = new Notification(icon, tickerText, when); please find this line in above code..this line is display icon of notification in statusbar. – dipali Aug 21 '13 at 06:24
  • this will create a default notification, check http://developer.android.com/reference/android/app/Notification.html – Sunil Mishra Aug 21 '13 at 06:30
  • dipali this is to create one on the left side as a simple notification . . . I know this . . . what we want is to get this on the right side along with the signal strength and battery icon – Prince Champappilly Aug 21 '13 at 07:00
  • it is built-in functionality to display notification. – dipali Aug 21 '13 at 07:04
  • yes yes everyone knows how to make notification . . . ty for ur effort tho . . . but im not looking for "how to display notification" – Prince Champappilly Aug 21 '13 at 08:42
