android - Android Realm openTransaction不返回

我正在尝试将我的应用程序中的Realm从版本0.85更新到版本4.1.1。在某些情况下，realm.beginTransaction不返回。我试图用realm.executeTransaction替换它，但没有任何效果。以下是Realm的详细日志：

V/REALM_JNI:  --> Java_io_realm_internal_OsSchemaInfo_nativeCreateFromList
V/REALM_JNI:  --> Java_io_realm_internal_OsRealmConfig_nativeCreate
V/REALM_JNI:  --> Java_io_realm_internal_OsRealmConfig_nativeSetInMemory -1605354496

V/REALM_JNI:  --> Java_io_realm_internal_SharedRealm_nativeBeginTransaction -1605349584

因此，在我看来，Relam在调用SharedRealm.nativeBeginTransaction时卡住了，这与调试时看到的匹配。

这是我的项目build.gradle

buildscript {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
        classpath 'com.google.gms:google-services:3.1.0'
        classpath ('io.realm:realm-gradle-plugin:4.1.1'){
            exclude group: 'com.google.guava'
        }
        classpath ('com.google.firebase:firebase-plugins:1.1.0'){
            exclude group: 'com.google.guava', module: 'guava-jdk5'
        }

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

而我的模块build.gradle

apply plugin: 'com.android.application'

    }



    defaultConfig {

        targetSdkVersion 26
        versionCode code
        versionName "$version"

        multiDexEnabled true
    }

    aaptOptions {

        }
        debug {
            buildConfigField "boolean", "DEV", "true"
            signingConfig signingConfigs.release
        }
    }
}

我正在使用Android Studio 3.0，并且必须启用D8才能进行构建

对发生的事情有任何想法吗？

最佳答案

发生问题是因为realm.beginTransaction（）如果被同时在不同线程上发生的写事务阻止，则不会返回。就我而言，这是由于调用RealmResults.clear（）造成的。通过用deleteAllFromRealm（）替换它来修复此问题。
