Question

我的应用程序在调试中运行正常，但在创建apk以发布时，我收到了关注错误。

Process: neocom.dealerbook, PID: 9044
    java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0

这是MapActivity.java:103

Callback<ClienteConfiguracao> callback = new Callback<ClienteConfiguracao>() {
                int failCount = 0;
            @Override
            public void success(ClienteConfiguracao clienteConfiguracao, Response response) {
                currentClient = clienteConfiguracao.getDealerships().get(0); /* Line 103 */
                setupToggles(currentClient);

                List<String> mAuthorization = clienteConfiguracao.getAuthorization();
                toAllowPermissions = new HashMap<>();
                Set<String> allImplementedKeys = PermissionManager.ALL_PERMISSIONS.keySet();
                for (String key : mAuthorization) {
                    if (allImplementedKeys.contains(key)) {
                        List value = PermissionManager.ALL_PERMISSIONS.get(key);
                        toAllowPermissions.put(key, value);
                    }
                }

这是我构建的proguard文件，用于搜索我收到的错误，Retrofit网站和其他人。

-assumenosideeffects class android.util.Log {
    public static boolean isLoggable(java.lang.String, int);
    public static int v(...);
    public static int i(...);
    public static int w(...);
    public static int d(...);
    public static int e(...);
}
-dontwarn retrofit.**
-dontwarn com.squareup.okhttp.**
-dontwarn okio.**
-dontwarn retrofit.appengine.UrlFetchClient
-keep class retrofit.** { *; }
-keep class com.squareup.okhttp.** { *; }
-keep interface com.squareup.okhttp.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation*
-keepattributes SourceFile
-keepattributes LineNumberTable


-keepclasseswithmembers class * {
    @retrofit.http.* <methods>;
}

有没有关于它的提示？

Answer 1

使用gson进行改造时，将Progard规则添加到序列化和反序列化的类中非常重要。

例如：

-keep class com.example.model.** { *; }

PS：另一个建议是使用rules snippets from this repository。许多不同的库都有规则。

Answer 2

问题出在这里

currentClient = clienteConfiguracao.getDealerships().get(0);

clienteConfiguracao.getDealerships()为空。您需要检查它是否包含

的元素

if (clienteConfiguracao.getDealerships().size() > 0) {
    clienteConfiguracao.getDealerships().get(0);
} else {
    //handle empty ArrayList
}

Answer 3

只需添加-keep class com.google.gson.** { *; }

即可

Answer 4

在app build

中使minifyEnabled为false

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

Proguard配置使用改造改造
