I have a android application (Java) that uses an Android Library. Everything works fine, but I need to wrap this application into a Xamarin application. So I decided to transform this application into a 2nd Android Library. I created my Xamarin Android application, and an Android Java Bindings Library project in which I added the two .aar files to the "Jars" folder.
The problems come when I try to compile this binding project. I get a lot of errors like this one :
/.../obj/Release/generated/src/Com.Google.Common.Util.Concurrent.ForwardingListenableFuture.cs(17,17): Error CS0102: The type `Com.Google.Common.Util.Concurrent.ForwardingListenableFutureInvoker' already contains a definition for `id_delegate' (CS0102)
When I open the generated ForwardingListenableFuture.cs file there's this code :
[global::Android.Runtime.Register ("com/google/common/util/concurrent/ForwardingListenableFuture", DoNotGenerateAcw=true)]
internal partial class ForwardingListenableFutureInvoker : ForwardingListenableFuture, global::Com.Google.Common.Util.Concurrent.IListenableFuture {
public ForwardingListenableFutureInvoker (IntPtr handle, JniHandleOwnership transfer) : base (handle, transfer) {}
protected override global::System.Type ThresholdType {
get { return typeof (ForwardingListenableFutureInvoker); }
}
static IntPtr id_delegate;
// Metadata.xml XPath method reference: path="/api/package[@name='com.google.common.util.concurrent']/class[@name='ForwardingListenableFuture']/method[@name='delegate' and count(parameter)=0]"
[Register ("delegate", "()Lcom/google/common/util/concurrent/ListenableFuture;", "GetDelegateHandler")]
protected override global::Com.Google.Common.Util.Concurrent.IListenableFuture Delegate ()
{
if (id_delegate == IntPtr.Zero)
id_delegate = JNIEnv.GetMethodID (class_ref, "delegate", "()Lcom/google/common/util/concurrent/ListenableFuture;");
return global::Java.Lang.Object.GetObject<global::Com.Google.Common.Util.Concurrent.IListenableFuture> (JNIEnv.CallObjectMethod (Handle, id_delegate), JniHandleOwnership.TransferLocalRef);
}
static IntPtr id_delegate;
// Metadata.xml XPath method reference: path="/api/package[@name='com.google.common.util.concurrent']/class[@name='ForwardingFuture']/method[@name='delegate' and count(parameter)=0]"
[Register ("delegate", "()Ljava/util/concurrent/Future;", "GetDelegateHandler")]
protected override global::Java.Util.Concurrent.IFuture Delegate ()
{
if (id_delegate == IntPtr.Zero)
id_delegate = JNIEnv.GetMethodID (class_ref, "delegate", "()Ljava/util/concurrent/Future;");
return global::Java.Lang.Object.GetObject<global::Java.Util.Concurrent.IFuture> (JNIEnv.CallObjectMethod (Handle, id_delegate), JniHandleOwnership.TransferLocalRef);
}
static IntPtr id_delegate;
// Metadata.xml XPath method reference: path="/api/package[@name='com.google.common.collect']/class[@name='ForwardingObject']/method[@name='delegate' and count(parameter)=0]"
[Register ("delegate", "()Ljava/lang/Object;", "GetDelegateHandler")]
protected override global::Java.Lang.Object Delegate ()
{
if (id_delegate == IntPtr.Zero)
id_delegate = JNIEnv.GetMethodID (class_ref, "delegate", "()Ljava/lang/Object;");
return global::Java.Lang.Object.GetObject<global::Java.Lang.Object> (JNIEnv.CallObjectMethod (Handle, id_delegate), JniHandleOwnership.TransferLocalRef);
}
}
Indeed, the "id_delegate" is duplicated..
I also have warnings like this related to the 1st .aar (not the application one) :
/../JARTOXML: Warning J2X9001: Couldn't load class com/company/project/controllers/activities/MenuActivity : java.lang.NoClassDefFoundError: android/support/v4/app/FragmentActivity (J2X9001)
