Question

某些服务器返回时会出现此错误。我正在使用异步任务。我已经改为改装，但错误仍然存在。据我所知，我不在代码中使用lambda表达式。我该如何解决这个错误？如果有必要，我可以把类代码。

错误：

引起：java.lang.ClassNotFoundException：路径上没有找到类“java.lang.invoke.MethodType”：DexPathList [[zip文件]   “/data/app/br.com.sis.app.aten-1/base.apk”，zip文件   “/data/app/br.com.sis.app.aten-1/split_lib_dependencies_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_0_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_1_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_2_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_3_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_4_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_5_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_6_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_7_apk.apk”，zip   文件“/data/app/br.com.sis.app.aten-1/split_lib_slice_8_apk.apk”，zip   文件   “/data/app/br.com.sis.app.aten-1/split_lib_slice_9_apk.apk"],nativeLibraryDirectories=[/data/app/br.com.sis.app.aten-1/lib/arm，   / system / lib，/ vendor / lib]]

这是我的傻瓜：

    apply plugin: 'com.android.application'

    android {
        compileSdkVersion 27
        buildToolsVersion "27.0.3"

        defaultConfig {
            applicationId "br.com.sis.app.aten"
            minSdkVersion 16

            versionCode 1
            versionName "0.0.0.5"
            multiDexEnabled true
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

        buildTypes {
            debug {
                debuggable true
            }
            release {

            }
        }
    }

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

app在这行asyncTask类中断：

@Override
protected void done() {
    try {
        postResultIfNotInvoked(get());
    } catch (Exception e) {
    ....
    }
}

Gson在休息前通过的方法：

public static Object parseJsonObjectToObject(JsonObject jsonObject, Object object) throws CommonsException {
    try {
        Gson gson = createGsonObject();

        String nameClass = object.getClass().getCanonicalName().toString();//CRASH!!!!!!
        Object objectParseGson = null;

        objectParseGson = createObject(nameClass);
        objectParseGson = gson.fromJson(jsonObject, object.getClass());

        return objectParseGson;

    } catch (Exception e) {
        throw new CommonsException(e.getLocalizedMessage(), e.getMessage());
    }
}

任何人都可以帮我吗？它并非在每种情况下都会中断，其他类似的项目也能顺利运行。

按照评论中的提示解决如下问题。

我有一个实例化应用程序的类：

public class MyApplicationInstance extends Application {

    private static MyApplicationInstance instanceApplication;

    private String dsChaveAcessoWbs;
    private Tracker mTracker;

    /**
     * Verificação de instancia devido uso da camera
     */
    public MyApplicationInstance() {

        if (instanceApplication == null) {
            instanceApplication = this;
        }
    }

    public static MyApplicationInstance getInstanceApplicationSingleton() {

        return instanceApplication;
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }
...
}

我在此课程中将Application更改为MultiDexApplication并且有效。

public class MyApplicationInstance extends MultiDexApplication {

    private static MyApplicationInstance instanceApplication;

    private String dsChaveAcessoWbs;
    private Tracker mTracker;

    /**
     * Verificação de instancia devido uso da camera
     */
    public MyApplicationInstance() {

        if (instanceApplication == null) {
            instanceApplication = this;
        }
    }

    public static MyApplicationInstance getInstanceApplicationSingleton() {

        return instanceApplication;
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }
...
}

我按照谷歌文档： https://developer.android.com/studio/build/multidex.html

错误ClassNotFoundException：未找到类“java.lang.invoke.MethodType”
