Proguard config to use retrofit Retrofit

my app is running all ok in debug, but when creating apk to release, I'm getting the follow error.

Process: neocom.dealerbook, PID: 9044
java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0
at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:255)

Here is the MapActivity.java:103

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

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);

Here is the proguard file that I build searching for the errors that I got, Retrofit site and others.

-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>;

Is there any tip about it?

Answer Source

When using retrofit with gson is important to add the Progard rule to the classes that are serialized and deserialized .

For example:

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

PS: Another advice is to use the rules snippets from this repository. There are rules for a lot of different libraries.
