FirebaseApp initialization unsuccessful - error crashing app

In my main Activity right after i try to initialize the two references it crashes, only to find out the error "FirebaseApp initialization unsuccessful"
private StorageReference mStorageReference;
private DatabaseReference mDatabaseReference;
mStorageReference = FirebaseStorage.getInstance().getReference("uploads");
mDatabaseReference = FirebaseDatabase.getInstance().getReference("uploads");
there is some code between the private declaration and the code itself, but that is not relevant to this problem
The manifest is:

I set up everything with Tools-Firebase, and i know that the code looks like it is glued together, since it is. I've been going through threads and just added things but nothing worked. If this matters, i am running the app on my phone, not emulator.

Is your google-json file is well setted ?
Also Firebase needs time to connect to it server and gives you the instance referred to your device , give it some time or use a promise to make sure firebase is connected to it server and instance is generated, then perform the action that need firebase instance.

In build.gradle(Project) I Changed 'com.google.gms:google-services:4.1.0' To 'com.google.gms:google-services:4.2.0' and the problem is solved

This one here is non-sense, because that's a Gradle plugin:
dependencies {
implementation 'com.google.gms:google-services:4.2.0'
}
And this one belong to the bottom of the file:
apply plugin: 'com.google.gms.google-services'

Manifest merger failed with multiple errors, see logs on Android Studio

The error says that "Error:Execution failed for task ':app:processDebugManifest'. > "
I have tried many solutions on this website but still, the problem is not solved. Please help me

On Merged Manifest says that
Merging Errors: Error: tools:replace specified at line:5 for attribute
android:appComponentFactory, but no new value specified app main
manifest (this file), line 4 Error: Validation failed, exiting app
main manifest (this file)

For me, the solution was to just migrate to AndroidX.
On Android Studio, go to:
Refactor > Migrate to AndroidX
clean the project.

I.m delete this
tools:ignore="GoogleAppIndexingWarning",
tools:replace="android:appComponentFactory"
and fix this problem.good luck :)

Just remove the below line:
tools:replace="android:appComponentFactory"
And recompile and finally it works for me!

you should try this:
1:Remove tools:replace="android:appComponentFactory"
2:Provide new value for android:appComponentFactory" attribute
from:
Manifest merger failed, error on compiling
it worked for me!

solve my problem
Refactor > Migrate to AndroidX

In my case an error in Manifest file brought about this error at the time of generating apk although app was building flawlessly.
It was want of explicit 'exported' attribute in activity elements in Manifest file. after that apk too generated successfully .

Failed to resolve all androidx libraries

I've added the library for the Room database. It was a androidX library. I didn't know a lot about libraries (I am a beginner) and also didn't know about AndroidX. I got these manifest merger errors and while resarching for a solution, I found out about the AndroidX libraries. So I wanted to migrate my project to AndroidX, but Android Studio can't resolve any of these libraries.

Try adding these in your project build.gradle file,
buildscript {

jcenter()
maven { url 'https://maven.google.com' }
mavenCentral()
}
...
}
allprojects {

For Kotlin DSL
repositories {
maven { setUrl("https://maven.google.com") }
}

Java code cannot access Kotlin's package since Kotlin 1.0.0 [duplicate]

After updating kotlin to RC-1036 i'm facing a weird issue: my code is not even compiled and packed.
When build passes and the app is launched i'm getting ClassNotFoundException: Didn't find class "example.myapplication.MainActivity".
I have tried to decompile apk with apktool and didn't find my classes inside the archive. There are no classes in build/intermediates dir either.
This is my project:

super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
hello.text = "New text"
}
}
Build tools version is 2.0.0-beta2;
Might be something wrong with sourseSets, though nothing works if i try to reconfigure it somehow. Appreciate any help.

You should have both these plugins:
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
The first makes sure the Kotlin code compiles, the second is for the UI imports.

Noclassdeffounderror - Can't find v7 support (android studio)

so im trying to build an app using GCM. i've opened 2 modules for this. a backend (GCM messaging with appengine and a regular module - the names are "app" (regular module" and "backend").
i'm recieving this problem and i can't figure the solotion for it.
when the app is starting i get the following error:

doew anyone knows how to fix it???

Problem Solved!
Ok so i did the following:
manifast:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.daniel.testing6" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission
android:name="com.example.gcm.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />
<application
android:name="com.example.daniel.testing6.Application"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity

android:label="#string/app_name" >

</intent-filter>
</activity>
<activity
android:name=".Main2Activity"
android:label="#string/title_activity_main2"
android:theme="#style/AppTheme.NoActionBar" >
</activity>
</application>
</manifest>
ok so to get rid of the error i went to the gradle of my module app:
so it will look like that:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "23.0.0 rc2"
defaultConfig {
applicationId "com.example.daniel.testing6"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(path: ':backend', configuration: 'android-endpoints')
//
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.google.android.gms:play-services:8.1.0'
compile 'com.android.support:multidex:1.0.0'
compile 'com.android.support:design:22.2.1'
}
next i created an Application as follows:
package com.example.daniel.testing6;
import android.content.Context;
import android.support.multidex.MultiDex;
import android.support.multidex.MultiDexApplication;
/**
* Created by Daniel on 05-Oct-15.
*/
public class Application extends MultiDexApplication {
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
and a main activity normally:
package com.example.daniel.testing6;
import android.content.Context;
import android.content.Intent;
import android.os.PersistableBundle;
import android.support.multidex.MultiDex;
import android.support.multidex.MultiDexApplication;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends ActionBarActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startActivity(new Intent(this, Main2Activity.class));
}
}
the manifast calls the Application that uploading all its data and then moves to the activity once the data is with in our reach :)

You also have to:
Include `compile 'com.android.support:multidex:1.0.0'` in your dependencies
See https://developer.android.com/tools/building/multidex.html for more details.
Also have your Application class extend MultiDexApplication instead of just Application. Alternatively, you can call MultiDex.install() in attachBaseContext() of your application

Installing/updating Android Support Library and Android Support Repository in SDK manager will fix such errors
