Question

我们想在我们的应用程序中集成Realm，我们遇到了以下问题：

StaticLoggerBinder的样子：

public class StaticLoggerBinder implements LoggerFactoryBinder {

    private static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();

    private static final String loggerFactoryClassStr = AndroidCustomLoggerFactory.class.getName();

    private final ILoggerFactory loggerFactory = new AndroidCustomLoggerFactory();

    private StaticLoggerBinder() {
    }

    public static final StaticLoggerBinder getSingleton() {
       return SINGLETON;   // line 27
    }

    public ILoggerFactory getLoggerFactory() { //line 30
       return this.loggerFactory;
    }

    public String getLoggerFactoryClassStr() {
       return loggerFactoryClassStr;
    }
}

根据我的理解，问题可能出在Realm的变换器上。它希望在我们的代码中包含一些未知的记录器。我们的应用程序的主要问题是，我们有一些第三方库，也使用SLF4J，我们无法修改它。我尝试使用0.90.1版本，而第三方库使用的SLF4J是1.6.4版本。 Dexguard是7.1.26。

另请注意，Realm适用于我的环境和具有相同依赖关系的另一个项目，但第三方库和SLF4J除外。

依赖项列表：

plugins:
apply plugin: 'com.android.library'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'dexguard'
apply plugin: 'realm-android'

dependencies:
provided 'javax.annotation:jsr250-api:1.0'
apt 'com.google.dagger:dagger-compiler:2.0.2'
compile([
        'com.google.dagger:dagger:2.0.2',
        'com.mcxiaoke.volley:library:1.0.18',
        'com.google.code.gson:gson:2.3.1',
        'io.reactivex:rxjava:1.0.11',
        'io.reactivex:rxandroid:0.24.0',
        'com.jakewharton.timber:timber:3.1.0',
        'com.squareup.okhttp:okhttp:2.6.0',
        'com.squareup.okio:okio:1.6.0',
        'com.android.support:support-v4:22.1.1'
])
compile files('libs/libconceal.jar')
compile files('libs/conceal_android.jar')
compile files('../dexguard/dexguard-runtime.jar')

compile files('libs/slf4j-api-1.6.4.jar')
compile files('libs/lib3rdparty.jar')

retrolambdaConfig 'net.orfjackal.retrolambda:retrolambda:2.3.0'

这可能吗，Realm在这里搞乱了吗？有什么办法可以阻止吗？

Realm不能与SLF4J一起使用？
