Have you registered your provider in the AndroidManifest.xml file?
as it is said in docs
If Yes, you will need to provide more information about how you work with the FileProvider class

RuntimeException: Unable to instantiate application com.company.app.Application: ClassNotFoundException

I've read a few answers on this site with the same or similar error messages, and I've tried all the solutions already. Sadly, none of them have worked so far.
My gradle files all look like they're properly set up for Multidex, the Application class extends MultiDexApplication and is referenced correctly in the manifest, I've cleaned all caches and restarted the IDE, deleting builds from the project and the device and re-building/re-installing, etc. etc.
Inspecting the APK, I found the Application in classes2.dex, correctly referencing .super Landroidx/multidex/MultiDexApplication;
The stack I'm getting is like this:

Can anyone figure out what this is all about?

In the module level build.gradle, we added these lines:
// Near the top
apply plugin: 'com.google.firebase.crashlytics'
// ...
android {
// ...
compileOptions {
sourceCompatibility 1.8
targetCompatibility 1.8
}
// ...
}
// ...
I have no idea how this fixed this crash, but I suppose that's what I get for using "It just works" libraries.

For Realm 3.7.1-3.7.2, Stetho-Realm won't work at all (unless you fork it and fix it for the code)
For Realm 4.0.0+ (that includes your version Realm 5.11.0), you need to use WickeDev's fork that supports Realm 4.0+.
repositories {
maven { url 'https://github.com/WickeDev/stetho-realm/raw/master/maven-repo' }
}

google maps api app keeps stopping in android studio

I am trying to create an application which utilizes Google Maps API. I followed the instructions (installed Google Play Services, created an API key, copied, and then pasted it in .xml file), but when I try to run this app, I get "Maps Demo (the name of the app) keeps stopping" message. (I use Nexus 5 API 28 AVD as an emulator) What might be reasons for that and how to solve this problem?

Avoid using play-services as whole in your gradle file.
compile 'com.google.android.gms:play-services:9.8.0'
instead use specific ones
compile 'com.google.android.gms:play-services-location:9.8.0'

Configure your app for multidex
Modify the module-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:
android {
defaultConfig {
...
minSdkVersion 15
targetSdkVersion 28
multiDexEnabled true
}
...
}
dependencies {
implementation "androidx.multidex:multidex:2.0.1"
}
Depending on whether you override the Application class, perform one of the following:
If you do not override the Application class, edit your manifest file to set android:name in the tag as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<application
android:name="androidx.multidex.MultiDexApplication" >
...
</application>
</manifest>
If you do override the Application class, change it to extend MultiDexApplication (if possible) as follows:
public class MyApplication extends MultiDexApplication { ... }
Or if you do override the Application class but it's not possible to change the base class, then you can instead override the attachBaseContext() method and callMultiDex.install(this) to enable multidex:
> public class MyApplication extends SomeOtherApplication { #Override
> protected void attachBaseContext(Context base) {
> super.attachBaseContext(base);
> MultiDex.install(this); } }
Caution: Do not execute MultiDex.install() or any other code through reflection or JNI before MultiDex.install() is complete. Multidex tracing will not follow those calls, causing ClassNotFoundException or verify errors due to a bad class partition between DEX files.
