需要帮助处理由java.lang.IncompatibleClassChangeError引起的致命异常

Question

因此,我昨天在Android Studio中遇到了这个错误,这是我以前从未见过的,这是由过去3个月未触及过的一段代码引起的.这来自用于注册推送通知的代码,本周早些时候工作正常,但现在它导致了这个错误:

05-20 10:37:02.064 22471-22681/com.appname E/AndroidRuntime: FATAL EXCEPTION: IntentService[RegIntentService]
                                                               Process: com.appname, PID: 22471
                                                               java.lang.IncompatibleClassChangeError: The method 'java.io.File android.support.v4.content.ContextCompat.getNoBackupFilesDir(android.content.Context)' was expected to be of type virtual but instead was found to be of type direct (declaration of 'java.lang.reflect.ArtMethod' appears in /system/framework/core-libart.jar)
                                                                   at com.google.android.gms.iid.zzd.zzeb(Unknown Source)
                                                                   at com.google.android.gms.iid.zzd.<init>(Unknown Source)
                                                                   at com.google.android.gms.iid.zzd.<init>(Unknown Source)
                                                                   at com.google.android.gms.iid.InstanceID.zza(Unknown Source)
                                                                   at com.google.android.gms.iid.InstanceID.getInstance(Unknown Source)
                                                                   at com.appname.services.RegistrationIntentService.onHandleIntent(RegistrationIntentService.java:32)
                                                                   at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:65)
                                                                   at android.os.Handler.dispatchMessage(Handler.java:102)
                                                                   at android.os.Looper.loop(Looper.java:135)
                                                                   at android.os.HandlerThread.run(HandlerThread.java:61)

这是我的RegistrationIntentService类:

package com.appname.services;

import android.app.IntentService;
import android.content.Context;
import android.content.Intent;
import com.google.android.gms.gcm.GoogleCloudMessaging;
import com.google.android.gms.iid.InstanceID;
import com.appname.MainSharedPreferences;
import com.appname.R;
import java.io.IOException;

public class RegistrationIntentService extends IntentService {

    private static final String TAG = "RegIntentService";

    public RegistrationIntentService() {
        super(TAG);
    }
    public static void startService(final Context context) {
        final Intent intent = new Intent(context, RegistrationIntentService.class);
        context.startService(intent); //HERE is the line that is causing the crash
    }

    @Override
    public void onHandleIntent(Intent intent) {
        InstanceID instanceID = InstanceID.getInstance(this);
        try {
            String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId) , GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
            MainSharedPreferences.saveGCMInstanceToken(token, getApplicationContext());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

这是从我的MainActivity类调用上面的类的代码行:

RegistrationIntentService.startService(getApplicationContext());

有关我的MainActivity的一些信息,如果它有帮助......

public class MainActivity extends SocialActivity implements SeekBar.OnSeekBarChangeListener

public abstract class SocialActivity extends AppCompatActivity implements GraphRequest.GraphJSONObjectCallback

我试过跳回几个较旧的提交,但得到了同样的错误.这让我相信我的Android Studio或java版本可能存在问题.我更新了我的java版本并重新安装了Android Studio,仍然出现同样的错误.也尝试在旧版本的单独计算机上,仍然是相同的错误.

我甚至尝试根据本指南从GCM迁移到Firebase ,最终再次收到相同的错误.

我可以注释崩溃应用程序的行,它会正常运行,但之后我不再收到通知.

任何有关此事的帮助或建议将不胜感激!

编辑:这是我的相关编译/类路径语句...

在appname build.gradle中:

buildscript {
    repositories {
        jcenter()
    }
    repositories { mavenCentral() }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
        classpath 'com.google.gms:google-services:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

在app build.gradle中:

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    //...
}

allprojects {
    //...
}

android {
   //...
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.google.code.gson:gson:2.5'
    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support:recyclerview-v7:+'
    compile "com.google.firebase:firebase-messaging:9.0.0"
    //...
}

apply plugin: 'com.google.gms.google-services'

更新可能27:

我们刚刚发布了一个update(version 9.0.1)来修复我在第一次编辑中提到的不兼容性.
请更新您的依赖项,如果仍有问题,请告知我们.

谢谢!

原答案5月20日:

您遇到的问题是由于
play-services / firebase sdk v9.0.0和 com.android.support:appcompat-v7 >= 24
(与android-N sdk发布的版本)不兼容

您应该能够通过定位支持库的早期版本来修复它.喜欢:

compile 'com.android.support:appcompat-v7:23.4.0'
