How to add the correct admob or adview dependency to an Android app

I'm developing an app and I want to add an admob banner add to it. I asked the permissions in the manifest file for Internet and for the network state. Then I added the dependency for admob. After entering the dependency to the gradle file, the app in my phone app crashes during testing.
It happens when I add the dependency. I want to find the correct dependency or some how fix this if this happens because of another reason.
Here are the dependencies I added:
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
implementation 'androidx.cardview:cardview:1.0.0'
implementation 'com.google.android.gms:play-services-ads:18.3.0'
}

You need to add below Meta tag inside of Aplication in your Manifest
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:ignore="GoogleAppIndexingWarning">
//Add this
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="#string/admob_app_id" /> //Add here your admob app id
...
</application>
I hope this can help you!
Thank You.

I think you need to add 2 meta-data tags inside the manifest xml of your application.
<application>
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="#string/admob_app_id" /> // put your admob app id in quotes
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>
Hope this helps

React-native error: Manifest merger failed

Running my app got this error:
Manifest merger failed : Attribute application#appComponentFactory value=(androidx.core.app.CoreComponentFactory) from [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86
is also present at [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:7:5-117 to override.
I've tried to add to gradle.properties
android.useAndroidX=true
android.enableJetifier=true
and also (to AndroidManifest)
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"
and also (to build.gradle)
implementation "androidx.appcompat:appcompat:1.0.0"
replacing the previous
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
but not working for me.

}

It means that one of your libraries is using AndroidX. So, you have to convert your app to AndroidX.
android.useAndroidX=true android.enableJetifier=true Put these lines in your gradle.properties.
npm install --save-dev jetifier
npx jetify
npx react-native run-android (your app should correctly compile and work)
Call npx jetify run in the postinstall target of your package.json (Any time your dependencies update you have to jetify again)

After defining ButterKnife , Manifest merger failed : Attribute application#appComponentFactory error

I have a problem about android manifest file in my android project after adding ButterKnife dependency in gradle file.
When I run the program, it throws an error shown below.
Manifest merger failed : Attribute application#appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91

Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:6:5-21:19 to override.
Here is my file.
<application

}

You cannot use butterknife:10.x.x unless you also migrated to AndroidX. If you haven't migrated, you'll need to stick to 9.0.0 for now. Once you migrate, then you can update to 10.1.0 (or whatever is latest at that time). –

Solved
I have fixed it by deleting all the files in C:\Users\cc.AndroidStudio3.2\system\caches.

I also had the same problem this morning.
I thought this was due to migrating to AndroidX but
It was wrong. It may occur due to improper indexing and building for e.g. the indexing is force stopped. or due to some IDE issues.
The isuue resolved by deleting gradle and .idea folder in project
and clearing cache of Android Studio IDE by D:\Users\ABCD.AndroidStudio3.2\system\caches.
And issue was resolved.
Note:- Please take Project Backups Daily.

Solution for Android studio Arctic Fox and Higher Versions
Steps
Exit Android Studio
Delete caches folder from
C:\Users\{username}\AppData\Local\Google\AndroidStudio2020.3 // For Arctic Fox
Open Android Studio and your code has being Perfect
Check your Android studio version and Target that version folder at below location
C:\Users\{username}\AppData\Local\Google
Note : AppData folder is Hidden in Windows

Erasing the cache of the Android studio will resolve the problem, for that you have to go to:
C:\Users\user\.AndroidStudio3.5\system\caches
(On windows)
and on Mac:
~/.AndroidStudio3.5/system/caches
Delete all the files there and restart the Android studio.

I solved that by
Close project you are working on
//This enables deleting all cache files
Close android studio
navigate to .AndroidStudio folder and then sytem then cache
delete the cache
Go to your project folder delete delete gradle and .idea folder
delete app.iml file too
import project dont open as exixting.
Boom you done.

Delete caches folder of the android studio
Solutions for android studio 3.6 or below android studio 3.6
C:\Users\{user}\.AndroidStudio{version}\system\caches
And above android studio 3.6 or android studio arctic fox
C:\Users\{user}\AppData\Local\Google\AndroidStudio{version}\cache

Close android studio then delete the cache found in
C:\Users\**user**\.AndroidStudio3.6\system\caches
Important not to modify a file before having deleted the android studio cache
If you modify a file you risk not being able to recover your old code

Rename your project folder and delete .gradle and .idea file inside project folder

I am also facing the same issue so i am copy the files from Project location which is corrupted. In my case, there is list of files corrupted due to module added in Login Activity
build.gradle (Project)
build.gradle (App-level)
AndroidManifest.xml
activity_login.xml
ActivityLogin
Steps to solve the problem
I have deleting .iml and .idea file then restart the Android Studio.
Paste the content from Project Location which is corrupted
Commenting the code in which module classes available
Run the application
If you are using git then rollback the changes in corrupted files as copy-paste process as done in Step-2
Above one process is working for me.

It's only a project cache problem (if you see all files in Notepad, it will look fine. No file is corrupt.).
I have 100% working solution.
Close Android Studio
Copy project folder
Rename new project folder
Re-start Android Studio
File->New-> Import from new folder
Delete old folder.

Amazon Device Messaging Stub! Android Studio

I'm trying to integrate Amazon Device Messaging with Android Studio. First I followed (integrating-your-app-with-adm). When I call
ADM adm = new ADM(getActivity());
if (adm.isSupported()) {
// ...
}
There's this output on logcat:
E/AndroidRuntime(24472): java.lang.RuntimeException: Stub!
E/AndroidRuntime(24472): at com.amazon.device.messaging.ADM.(Unknown Source)
So I followed Amazons (Integrating Amazon Libraries with Android Studio ) with the same result.
Then I tried this and this without success.
My AndroidManifest.xml looks like this:
...
<uses-permission android:name="de.mypackage.permission.RECEIVE_ADM_MESSAGE" />
<uses-permission android:name="com.amazon.device.messaging.permission.RECEIVE" />
<permission android:name=".permission.RECEIVE_ADM_MESSAGE" android:protectionLevel="signature" />
...
<application
android:name=".MyPackageApplication"
android:allowBackup="true"
android:allowClearUserData="true"
android:hardwareAccelerated="false"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
...
<service android:name=".service.ADMNotificationService" android:exported="false" />
<amazon:enable-feature android:name="com.amazon.device.messaging" android:required="true" />
<receiver android:name=".service.ADMNotificationService$MessageAlertReceiver"
android:permission="com.amazon.device.messaging.permission.SEND">
<intent-filter>
<action android:name="com.amazon.device.messaging.intent.REGISTRATION" />
<action android:name="com.amazon.device.messaging.intent.RECEIVE" />
<category android:name="de.mypackage"/>
</intent-filter>
</receiver>
...
</application>
The local build.gradle looks like this:
...
dependencies {
...
provided files('libs/amazon-device-messaging-1.0.1.jar')
...
}
May you have an idea?

You probably have something along this lines in your dependencies section:
compile fileTree(include: ['*.jar'], dir: 'libs')
This means you're compiling all jars in libs folder into your app. So probably the answer that says switch compile to provided works, but in addition to provided you do compile for all jars in libs folder anyway.
You would need to remove the fileTree line, and include any jars you have there (excluding amazon-device-messaging-1.0.1.jar) manually.

The solution to fix the crash is to edit the build.gradle (Module:app) file.
Remove the line: compile fileTree(include: ['.jar'], dir: 'libs')*
Go to the libs folder and find out all the jar files you require
Include them one by one for compilation. For example, compile files('libs/ePOS2.jar')
Add ADM jar file provided files('libs/amazon-device-messaging-1.0.1.jar')
Build the project
