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)

Manifest Merge issues with Lottie

I was getting started with Lottie when I came across this error. I added the dependency to my build.gradle
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'org.jsoup:jsoup:1.11.2'
implementation 'com.airbnb.android:lottie:2.8.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'android.arch.navigation:navigation-fragment:1.0.0-alpha06'
implementation 'android.arch.navigation:navigation-ui:1.0.0-alpha06'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
Since I added implementation 'com.airbnb.android:lottie:2.8.0' build succeeds but I cant run my application as there is an error in the Manifest Merging.

</manifest>

The fact that the error has androidx.core.app.CoreComponentFactory points to the fact that the new "Jetpack" support library packages are being used. Seeing that your manifest uses the "older" packages points to the fact that it probably is used by lottie.
You can make sure that this is the reason by inspecting the library.
To resolve the issue you can use an older lottie library, start using the jetpack support library packages or resolve the merge manually. You can take a look at the merged manifest if you navigate to the AndroidManifest.xml and switch to the Merged Manifest tab at the bottom of the window.

Suggestion:
add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:14:5-35:19 to override.app main manifest (this file), line 21

Unresolved package "generated" in AndroidManifest.xml

In my Android Studio androidManifest.xml file, I found an unresolved package generated. How can I fix it?
The issued code is : android:name=".provider.generated.SquawkProvider
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.aaa">

</service>
</application>
</manifest>

This issue stems from annotation processing now being included in Gradle from version 2.2. You can fix project and get it running with the following changes.
Project level "build.gradle" remove this line:
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.2'
App level "build.gradle" remove this line:
apply plugin: 'android-apt'
and change this line replacing apt with annotationProcessor:
apt 'net.simonvt.schematic:schematic-compiler:0.6.3'

In build.gradle(Module:app)
remove this two line
1) Top on the file
apply plugin: 'android-apt'
2) in dependencies
apt 'net.simonvt.schematic:schematic-compiler:0.6.3'
add this
annotationProcessor 'net.simonvt.schematic:schematic-compiler:0.6.3'

If the above responses don't work for you, make sure you are using the latest version of Android Studio and gradle plugin (4.4 as of this post) and have changed all the 'compile' lines with 'implementation'.
After that try Build -> Clean Project then Build -> Rebuild Project. (All of this after following #drspaceboo's answer of deleting classpath and plugin lines, then changing apt to annotationProcessor.)

Try this:-
Go to File -> Invalidate Caches / Restart and then Invalidate and Restart.

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

AdMob error: Didn't find class "com.google.ads.AdView"

So I'm on Android Studio v 0.3.6 and I'm having problems with Google Play Services. I was already using the Admob jar in my project but I had to update it so I tried to add them via the instructions. My project compiles fine however when I try to run an activity I get the following error:
Didn't find class "com.google.ads.AdView" on path: /data/app/com.mre. example-1. apk
See the full error output here Relevant portion of my build.gradle:

Over the past two days I have tried every variation of adding the GPS library to my project, to just the jar to both to none. At first I deleted the jar from my /libs and added the required lines to my build.gradle but that didn't work either. I thank you in advance for any help you can provide.

The package changed to com.google.android.gms.ads.AdRequest and com.google.android.gms.ads.AdView
Change your import and your layouts
Follow this tutorial to migrate your apk.

In my case I forget to add google_play_services_lib to my project. I fixed that by adding this library... Hope it will help someone...

Landed in similar problem while configuring firebase. Need to add play-services as dependency in app level gradle file -
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.google.android.gms:play-services:9.0.0'
}
Important part here is -
compile 'com.google.android.gms:play-services:9.0.0'
Post this sync your project and all required classes should be available.
