Develop Reference

App Logo shows in debug apk but not in release apk | Android

So I have been working to add a logo to my app in android studio. I did it via right click on mipmap folder -> new -> Image Asset -> Selecting image asset -> next -> finish. After this my mipmap folder looks like the below image:
mipmap folder screenshot
I can clearly see that there is debug written on all the images added by me.
Now whenever I build a signed apk and select release mode the logo does not show up in the app but in debug mode it does. Please help me out and let me know how I can have the logo show up in release build as well.
For your refrence I am adding my Manifest and build.gradle files:
build.gradle file looks like this
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
}
android {
namespace 'com.nomaanh.deliveryappcommissioncalculator'
compileSdk 32
defaultConfig {
applicationId "com.nomaanh.deliveryappcommissioncalculator"
minSdk 21
targetSdk 32
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
buildFeatures{
viewBinding true
}
}
dependencies {
implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.appcompat:appcompat:1.5.1'
implementation 'com.google.android.material:material:1.7.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.4'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.0'
}
And my AndroidManifest.xml file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</application>
</manifest>
I tried deleting the release ic_launcher.xml/ic_launcer_round.xml but that brought up some linking error while building the app, I also tried changing the foreground property to my logo in the files itself but that also didnt help.

You probably missed Res Directory selection step in Android studio while adding the image asset. Here's how you need to add the app icon for both debug and release build in Android Studio:-
right click on mipmap folder -> new -> Image Asset -> Selecting image asset -> next -> Click on Dropdown menu in front of Res Directory -> Select main as an option ->finish

I am getting blank screen after integrating google maps api in my android application

I tried integrating google maps API in my android application but I keep getting a blank grey screen. Attaching manifest and build.gradle file. The activity file contains the default code that comes while creating a google maps activity. You can clearly see this in manifest file.
I have mentioned the API key. I think the issue lies in dependencies, I might not have included every library that requires in order to run the app but I am not able to figure it out.

AndroidManifest.xml "Unresolved package" Error

I am developing a Media Player app. I was implementing MediaButtonReceiver (which is used to control Media inputs given from Headphone, bluetooth like external devices).
But while declaring receiver in the manifest file I encountered a number of errors.
Errors:
Unresolved package session
Unresolved class MediaButtonReceiver
Class referenced in the manifest, com.example.android.MediaPlaybackService, was not found in the project or the libraries
Unresolved package android
Unresolved class MediaPlaybackService

"Unresolved package/reference" means that the supporting library doesn't exist. According to the bewildering Android dev doc, you must download it by adding the following code to Gradle Scripts > build.gradle (Module: xxx.app) inside dependencies{}, resync and the error will disappear from androidx.media.session.MediaButtonReceiver
implementation("androidx.media:media:1.6.0")
and add this code for the error to disappear from android.support.v4.media.session.MediaButtonReceiver
implementation("com.android.support:support-media-compat:28.0.0")
Check latest version of androidx and v4

Maybe try to declare it in AndroidManifest.xml like the documentation said (for AndroidX) :
<receiver android:name="androidx.media.session.MediaButtonReceiver" >
<intent-filter>
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</receiver>

Why my emulator is throwing me the error, missing system image?

Well, actually, I am a newbie to android. I have been trying to develop an app that has google maps, and everything was going fine until today when I got this error from the emulator.
Here are some files in case it may be helpful.

PS: By the way, if you guys have time, could you please guide me on how to add google maps to an already-created fragment(for example, my fragment is the one of a bottom navigation). I have been searching but all I tried did not work for some reason. Or just a link to the valid way would do because there seemed to be many obsolete approaches to this as well, which we beginners cannot really discern.

App doesn't show up in Laucher List and can't be opened

I made an app, that worked just fine until yesterday.
Somehow I broke it that it doesn't show up in the Launcher's App list. I only can uninstall through the Apps tab in the Settings.
As I have already made a Beta on Play Store I tried to open it there, but there only shows up the "Uninstall" button.
I think it has to do something with the Manifest or build.gradle.
So here they are:
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="at.mrminemeet.reviewcheck">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.SEND"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/*"/>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Information"></activity>
</application>
</manifest>
And here the build.gradle (Module: App):
apply plugin: 'com.android.application'
android {
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
signingConfigs {
}

defaultConfig {

minSdkVersion 21
targetSdkVersion 27

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

}
}

}
If you need other files just comment on them.

If you want to use multiple category then you need to create another intent-filter
like this
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.SEND"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/*"/>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
