Given I have a model class RemoteMediaFile, which is roughly defined like this:
public class RemoteMediaFile implements Parcelable {
private String mId;
private String mParentId;
public RemoteMediaFile() {
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.mId);
dest.writeString(this.mParentId);
}
private RemoteMediaFile(Parcel in) {
this.mId = in.readString();
this.mParentId = in.readString();
}
public static final Creator<RemoteMediaFile> CREATOR = new Creator<RemoteMediaFile>() {
public RemoteMediaFile createFromParcel(Parcel source) {
return new RemoteMediaFile(source);
}
public RemoteMediaFile[] newArray(int size) {
return new RemoteMediaFile[size];
}
};
}Then I'd like to use @Extra in my Activity, which should read the array from an Intent:
@EActivity
public class RemotePhotoDetailActivity extends BaseActivity implements RemotePlayer{
@Extra
protected RemoteMediaFile[] remoteFiles;
}However, this creates a ClassCastException:
Caused by: java.lang.ClassCastException: android.os.Parcelable[] cannot be cast to com.myapp.media.RemoteMediaFile[]

The generated code looks like this:
private void injectExtras_() {
Bundle extras_ = getIntent().getExtras();
if (extras_!= null) {
if (extras_.containsKey(REMOTE_FILES_EXTRA)) {
remoteFiles = ((RemoteMediaFile[]) extras_.getParcelableArray(REMOTE_FILES_EXTRA));
}
}
}A fix would be to read the RemoteMediaFile[] object from the intent like this:
private void injectExtras_() {
Bundle extras_ = getIntent().getExtras();
if (extras_!= null) {
if (extras_.containsKey(REMOTE_FILES_EXTRA)) {
Parcelable[] a = extras_.getParcelableArrayExtra(REMOTE_FILES_EXTRA);
remoteFiles = Arrays.copyOf(a, a.length, RemoteMediaFile[].class);
}
}
}When I do this manually, it will work properly.
