Launcher icon cannot be seen - android

Indeed, as you guys may have guessed I am a newbie to android, and the issue I am asking is quite common; however, even when I did everything according to the tutorials and guides. The app icon is not changing. My emulator is API 25, and until now, I have tried uninstalling and reinstalling the app, checking the intent fillers in manifest folder, and deleting and re-getting the ic_launcher photo. Here, the photos of the some of my files.
Thanks.
By the way, this is how I implemented my picture.

App full screen problem, error "No resource found that matched the given name"

I have modified & created an app with apkeditor using html, css, javascript, jquery etc. Everything is going well, my app is running fine in all devices.
but i face a problem now after installing this app that it won't open with full screen area. and its showing extra black area on the bottom of this app.
If i want to do full screen it takes permission of fullscreen app or i can do it fullscreen manually from full screen app setting.
I tried to fix this with using several methods from stackoverflow here. But i can't fix this problem still now. Because the code of this app are being used by converted with smali files.
And i can't edited these files. An error shows me when i tried to add style.xml file, no title bar or other things.
The error is- "No resource found that matched the given name..."
Here i have shared this app via google drive.. (size:only 8mb)
https://drive.google.com/file/d/1JhsIeGO4_3SR7TkczNHPqqUOQbtRfagt/view?usp=drivesdk
I will be very greatfull if anyone fix this problem directly on this app or share me here the way of fixing it.
Thanks all the members of this community.

Building the game making two launcher icon of game in unity 3d for android

I am working on the Unity3D and its my first time on it, I was editing some code and that's gone fine , I know and read how to build the game and make the release apk and I did. But there is a problem which is as Under.
Problem :
When ever I install the game from Apk or directly from the Unity3D ,
both gives me 2 launcher icon. And those two launcher icon are able to run the game as expected. But I am not able to understand why there is two launcher icon.
What I want:
Well being as an android developer I know that there should be only
one launcher icon of game, But there are two . I want that there
should be one launcher Icon
Any idea why is it happening and what is a solution of it. ? Please help me as I am stuck in this problem.
I found the answer. I have followed the path to android plugin which is located inside the plugin folder. there I found the manifest file
I opened that manifest file and found that there are 2 activities with the name of property of LAUNCHER. which is meant to launch first among all of other activities.
So I set that intent category to DEFAULT and then I built the game again . And thus I found only one Launcher icon of game.
This solved my problem. Posting this as answer because I thought some one might fall in this same situation so in this case he may found this as a useful answer.

User complaining of Android app 'disappearing' following an update

A user of one of my Android apps has reported that his version 'disappeared' following an update. None of the other (thousands of) users have reported issues.
This morning I tried to open up the app but could not get anything.
I tried and tried and then physically turned my phone off and back on.
Now the icon has disappeared.
He has a lot of data stored in the app, so removing and re-installing isn't an option.
I think the problem has been caused by another apps update which happened yesterday.
I can see your icon in my apps list but it is the only one that is black and white, all the rest are in colour.
When I view the properties of your app it says:
Storage 20.00KB
Application 0.00KB
Data 20.00KB
It gives an option to clear data or uninstall.
My memory card, which I haven't removed, says I have 55mb of data left.
What could have caused this, is there anything I can do to avoid this happening to users in the future and is there anything I can suggest to remedy his problem?

Make android app icon available to other applications

I would like my application icon to be available to other applications.
I understand this is a bit unclear so will try explain:
Applications such as Astros program manager lists applications with their icon. For all apps this is the correct icon as on the launcher, except mine which is displaying the standard android icon. I have set my icon as the manifest using: android:icon="#drawable/runninglate"
This works on the launcher but Astro still shows the default icon from when I create the project (which I deleted a long time ago). I have also tried renaming my icon file to icon.png in case this was a standard. This also failed to work.
I am clearly doing something wrong, or have missed a setting somewhere, can some one point me in the right direction.
Make sure you have your icon in the <application> element, perhaps in addition to having it in the <activity> element of the activity that should appear in the Launcher.
Seems it was a caching issue. I re-flashed my phone today for an update and the correct Icon was shown using the same APK as I was using when it wasn't showing. Maybe a clear data on the displaying app was all that was required!
