android - Proguard breaks parameterized constructor injection -

i set test project see how can use roboguice , proguard injected parameterized constructor.

this proguard-rules.pro file:

-keep class roboguice.** { *; } -keep interface roboguice.** { *; } -dontwarn roboguice.**  -keep class org.roboguice.** { *; } -keep interface org.roboguice.** { *; } -dontwarn org.roboguice.**  -keepattributes **  -keep class com.example.vladfatu.roboguicetest.application.testmodule  -keep class com.google.inject.binder -keep class com.google.inject.module -keep public class com.google.inject.** { *; }  # keeps fields , constructors @inject -keepclassmembers,allowobfuscation class * { @com.google.inject.inject <fields>; @com.google.inject.inject <init>(...); } 

this testmodule:

public class testmodule implements module {  public testmodule() {     super(); }  @override public void configure(binder binder) {     binder.bind(stateprovider.class).to(roboteststateprovider.class); }  } 

this stateprovider :

public interface stateprovider {  string getstate(); } 

this roboteststateprovider :

public class roboteststateprovider implements stateprovider {  private context context;  @inject public roboteststateprovider(context context) {     this.context = context; }  @override public string getstate() {     return "state"; }  } 

and application class:

public class robotestapplication extends application {  @override public void oncreate() {     super.oncreate();      roboguice.setuseannotationdatabases(false);     configureinjection(); }  protected void configureinjection() {     roboguice.getorcreatebaseapplicationinjector(this, roboguice.default_stage, roboguice.newdefaultrobomodule(this), new testmodule()); } } 

when tries create application injector(in application class) fails error:

could not find suitable constructor in com.example.vladfatu.roboguicetest.monitor.roboteststateprovider. classes must have either 1 (and one) constructor annotated @inject or zero-argument constructor not private.

i thought "@com.google.inject.inject (...);" line proguard rules should have fixed this, hasn't. tried decompiling apk sure @inject annotation there(before constructor) , is, still doesn't work.

obviously, without proguard works fine... roboguice version use 3.0

if want context can either:

1. @inject property
2. use provider<context> argument constructor

and include below in proguard-rules.pro file:

-keep class com.google.inject.binder -keepclassmembers class * {     @com.google.inject.inject <init>(...); } -keepclassmembers class * {     @javax.inject.inject <init>(...); } # there's no way keep @observes methods, use orn*event convention identify event handlers -keepclassmembers class * {     void *(**on*event); } -keep public class * extends android.view.view {     public <init>(android.content.context);     public <init>(android.content.context, android.util.attributeset);     public <init>(android.content.context, android.util.attributeset, int);     public void set*(...); }  -keep public class roboguice.** -keep class roboguice.** { *; } -keep class org.roboguice.** { *; } -keep public class javax.** -keep public class javax.annotation.** -keep public @interface javax.annotation.** -keep public interface javax.annotation.** -keep public class com.actionbarsherlock.** -keep public class android.** -keep public class android.** { *; } -keep public class android.content.res.resources.theme -keep public class android.content.res.resources.theme { *; } -keep public class android.content.res.resources -keep public class android.content.res.resources { *; } -keep public class com.google.** { *; } -keep public class com.google.** -keep public class android.support.** -keep public interface android.support.**  # # added work #  #-dontwarn roboguice.activity.robosherlockpreferenceactivity -dontwarn com.actionbarsherlock.** -dontwarn com.google.android.maps.** -dontwarn javax.annotation.nullable -dontwarn roboguice.activity.robomapactivity -dontwarn roboguice.activity.sherlockaccountauthenticatoractivity -dontwarn javax.annotation.checkreturnvalue -dontwarn javax.annotation.concurrent.guardedby -dontwarn javax.annotation.parametersarenonnullbydefault -dontwarn sun.misc.unsafe -dontwarn javax.annotation.checkfornull -ignorewarnings
