How to create a Notification \\ status bar icon on

问题:

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.

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.

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.

public class GCMIntentService extends GCMBaseIntentService {

public static final String PROJECT_ID = "4898989797";
private static final String TAG = "GCMIntentService";
ModelNotificationMessage modelNotificationMessage;

public GCMIntentService() {
    super(PROJECT_ID);
    Log.d(TAG, "GCMIntentService init");
}

@Override
protected void onError(Context ctx, String sError) {
    // TODO Auto-generated method stub
    Log.d(TAG, "Error: " + sError);

}

@Override
protected void onMessage(Context ctx, Intent intent) {

    Log.d(TAG, "Message Received");

    String message = intent.getStringExtra("message");

    Log.d(TAG, "Message Received" + message);

    sendNotification(message);
    Intent broadcastIntent = new Intent();
    broadcastIntent.setAction("GCM_RECEIVED_ACTION");

    broadcastIntent.putExtra("gcm", message);

    ctx.sendBroadcast(broadcastIntent);
}




 private void sendNotification(String message) {
            // this
            String ns = Context.NOTIFICATION_SERVICE;
            NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

            int icon = R.drawable.notification;
            CharSequence tickerText = message; // ticker-text
            long when = System.currentTimeMillis();
            Context context = getApplicationContext();
            CharSequence contentTitle = modelNotificationMessage.getKey();
            CharSequence contentText = message;
            Intent notificationIntent = null;
            int NOTIFICATION_ID = 9999;



                NOTIFICATION_ID = CommonVariable.notification_message;
                notificationIntent = new Intent(this, ViewMessages.class);
                contentText = arrayList.get(0).getDescription();
                tickerText = arrayList.get(0).getDescription();

            // and this
            PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                    notificationIntent, 0);
            Notification notification = new Notification(icon, tickerText, when);
            // Play default notification sound
            notification.defaults |= Notification.DEFAULT_SOUND;
            notification.setLatestEventInfo(context, contentTitle, contentText,
                    contentIntent);
            mNotificationManager.notify(NOTIFICATION_ID, notification);
        }
