How do I change the app icon in the 'Recents' Screen? - android

I know how to change the icon of my app, but when I look at the Recents Screen, the icon is the default one.
App icon (all good so far):
Icon in my Recents Screen:
This is the 'application' tag of my 'AndroidManifest.xml'
<application
android:name=".App"
android:allowBackup="true"
android:icon="#mipmap/iconout"
android:roundIcon="#mipmap/iconout"
android:logo="#mipmap/iconout"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
I've tried many solutions that I found on this platorm (that didn't work), like:
file->new->image asset->choose image..
install & unistall the app
build & clean project
delete all the default icons on my project
drag & drop my icon to drawable from mipmap folder
Any other possible solutions? Thank you in advance!

Ok I found the solution and decided to answer for anyone that will encounter the same problem in the future.
I fixed it by adding android:icon="#mipmap/iconout" in the main activity tag declaration in the AndroidManifest.xml, like so:
<activity
android:icon="#mipmap/iconout"
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
And here's the final result:

Try to change the format of the icon to PNG. That works for me.
Or you could try the application on different devices to see if it's not a problem of the emulator/phone.

Android launcher icon only appears in the emulator

I'm trying to add a launcher icon to my android app. I have watched multiple tutorials online that explain how that works. I ended up doing it this way:
https://www.youtube.com/watch?v=DQ8HDL-X9rM
The laucher icon does appears in the android simulator but not on physical phones.
what I have tried to do:
clean the build in android studio
reset the icon the way it says in the tutorial
checked the reference in android manifest
checked if the icon was changed in the drawable and mipmap folders
that were the tips that showed up in a stackoverflow topic a couple years back.
I have been working on it for the passed week and I just can't get it to work.
This is my ic_launcher.xml
<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
<background android:drawable="#color/ic_launcher_background"/>
<foreground android:drawable="#mipmap/ic_launcher"/>
</adaptive-icon>
And this is this are the lines in my AndroidManifest
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
<activity android:name="com.example.fragments.Product">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.MainActivity" />
</activity>
<activity android:name="com.example.MainActivity">
<intent-filter>
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
</application>
Also I checked all the mipmap folders and all my icons are in there with the correct names.
Does anyone know what I can do?
---update june 3---
Now its not even showing up on the emulator anymore...
I have tried and read all the topics online I really hope someone can spot what I do wrong

Can I set the colour of the Launcher Icon?

I am writing a very simple app as a starter and using a material design icon as the launcher icon. Is there a way I can set the colour of just the launcher icon like I can the size and shape?
Here is my code from AndroidManifest.xml
<application
android:allowBackup="true"
android:icon="#drawable/gasstation"
android:label="#string/app_name"
android:iconTint="#color/sysGreen"
android:roundIcon="#drawable/gasstation"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
The statement android:iconTint seems to be OK in that Android Studio has not flagged it as an error but it has no effect. The launcher icon is still the grey colour of the downloaded image resource.
Is this possible? Any help greatly appreciated.
If you retrieve the icon from a drawable, basically a small image you have in your resources, you cannot change the color.
What you can instead do is to use the tool Image Asset Studio, here is the link
As explained
In the Project window, select the Android view. Right-click the res
folder and select New > Image Asset.
then follow the guide..
Anyway from API version 21, you can tint drawables,
as explained in this post
Well ... I finally did it as follows.
right click on res>new image asset>clip art>pick the icon
you can set the foreground colour manually in the Configure Image Asset screen

super.onCreate crashes after defining custom splash screen style to Activity?

I wanted to add a SplashScreen to my app and did a little research on the matter. Some tutorials said that you could create an activity and with some timers show it for a few seconds. I couldn't get them working, and then in this page How do I make a splash screen? the second top voted answer said that instead of showing an activity (and because of that wouldn't substitute the white/black launch loading screen but instead add more delays) you should instead create a custom style and assign it to your activity in the Manifest file. I did that, created a new Style like this:
<style name="splashScreenTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">#drawable/launchscreen</item>
</style>
in the styles.xml and changed my Manifest to this:
<application
android:name=".EFBApp"
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivityDrawer"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/splashScreenTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
When I run my app I can see the launch screen perfectly but then it crashes. By breakpoints I discovered that when the MainActivityDrawer (my main class) gets to the super.onCreate(savedInstanceState); line it then crashes (it goes to the ZygoteInit.java class and after that it crashes while breakpoint debugging). If I take away the android:theme lines in the Manifest it works fine but shows the horrible plain white screen while launching. Any suggestions or ideas? Thanks a lot.
Ok, so I managed to make it not crash, instead of assigning the parent as Theme.AppCompat.NoActionBar, I used just AppTheme and it works now. I hope this helps anyone.

How to change launcher icon and it's label from the application

How can I change the launcher icon and its label from my application runtime in Android? (if it is possible)
I mean the properties defined in AndroidManifest.xml: android:icon and android:label. I want to replace it by the image I take from the camera.
This entire answer is from this post and it was taken from P-A and CommonsWare.
You cannot change the manifest or the resource in the signed-and-sealed APK, except through a software upgrade. or
Try this, it`s work fine for me but not sure for all devices:
Modify your MainActivity section in AndroidManifest.xml, delete from it, line with MAIN category in intent-filter section.
<activity android:name="ru.quickmessage.pa.MainActivity"
android:configChanges="keyboardHidden|orientation"
android:screenOrientation="portrait"
android:label="#string/app_name"
android:theme="#style/CustomTheme"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />//DELETE THIS LINE
</intent-filter>
</activity>
Create <activity-alias> for your app, for each of your icons. Like this
<activity-alias android:label="#string/app_name"
android:icon="#drawable/icon"
android:name=".MainActivity-Red"
android:enabled="false"
android:targetActivity=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity-alias>
Set programmatically ENABLE attribute for necessary
getPackageManager().setComponentEnabledSetting(
new ComponentName("ru.quickmessage.pa", "ru.quickmessage.pa.MainActivity-Red"),
PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
Note, At least one must be enabled and above code perfect working up to 4.0 not tested into >4.0.
Edit: your original answer didn't specify you wanted to do it at runtime. Below the line is how to do it before it compiles. As for doing it programmatically at runtime:
From this answer:
You cannot change the manifest or the resource in the signed-and-sealed APK, except through a software upgrade.
But also, the accepted answer figured out a "hack" or some cheating way to do it (I presume). I haven't tested it, but there is a source for you to check out.
Or, this link apparently describes how to do this using the "widget" approach.
So lets say your manifest was like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="yourPackage"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
...
You would change the launcher icon by putting images into your drawable folders:
Project folder --> res --> all the drawables
Then you would change the android:icon="#drawable/ic_launcher" to be android:icon="#drawable/whateverTheNameOfTheImageIsYouPutInTheDrawablesFolders"
To change the label:
Open up your strings.xml file which is located:
Project folder --> res --> values --> strings.xml
And look for the string that looks like this:
<string name="app_name">Your App Name</string>
And just change Your App Name to be whatever you want the label to be.
Summary:
android:icon="#drawable/ic_launcher" determines your launcher icon, so just add images to the drawable folders and change ic_launcher to whatever the name of image is that you want to be the icon.
android:label="#string/app_name" determines your "label" so just look for app_name (because the label is referenced to #string/app_name) in your strings.xml file and change the contents of app_name.

Separate Launcher and Activity icon with Android

I've got a simple application with one single activity. Actually, the launcher icon is the same as the activity's one (the one in the top-left corner). I would like to put another icon in my activity without changing the launchers'one.
Here is my manifest :
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.natinusala.pebkac.MainActivity"
android:label="#string/app_name">
<intent-filter android:logo="#drawable/pebkac">
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Actually, I can edit the launcher and activity icon by editing the android:icon="#drawable/ic_launcher" line. I can do it also in adding an android:icon into the <activity> but it modify too the launcher's icon.
How can I do to edit my activity's icon without touching the launcher's one ?
Thanks !
In your manifest, add android:logo="#drawable/ic_yourIcon" to either your Activity or Application tag.
