Rejecting re-init on previously-failed class java.

This weird logcat messages started when I switched to supportLibrary 28, not happens on 27.1.1. I tried with an empty default project and the result exactly the same.

The problem is easily reproducible,

Create a new project with an empty activity and run on an emulator except API28 emulator. It'll give that error on my API21 emulator:

Rejecting re-init on previously-failed class java.lang.Class<android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper>

My API24 device shows more detailed log:

I tried API21 emulator, API24 hardware device and API 28 emulator. Only API28 emulator didn't produce that error.

I googled, searched SO and also reported to android issue tracker I can't find any solution and android team says that is an intended behavior. So I don't know what to do. Should I ignore an error message? Is there anybody have this issue?

build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    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'
}

MainActivity.java:

package com.example.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

</android.support.constraint.ConstraintLayout>

This happens when using a class that is not compatible with your minimum sdk version. The code compiles because it leaves it up to you for deployment. Try using a higher min sdk version to verify this.

Well, as it appears that Google isn't interested in fixing it; I've decided to (for now) force using support library 27; at least it fixes the crashes on the few devices that support lib 28 crash on.

The fix that I'm using is adding the following into build.gradle however note, this is for a fix for android; only works for users of com.android.support libraries.

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "com.android.support") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "27.+"
            }
        }
    }
}

If you replace AppCompatActivity with Activity in public class MainActivity extends AppCompatActivity, the warning will be gone as the conflict is related to AppCompat in Android X.

However, not the best solution if you need to keep the backward compatibility for older devices. Otherwise you can just ignore this warning until any fix will appear.
