Question

After finally getting the Android Facebook SDK to properly import thanks to this, I found that eclipse does not recognize the override of onclick in FbDialog.java:

mCrossImage.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mListener.onCancel();
        FbDialog.this.dismiss();
    }
});

Nor does it recognize the overrides of onServiceConnected and onServiceDisconnected in the TokenRefreshServiceConnection implementation of ServiceConnection

@Override
public void onServiceConnected(ComponentName className, IBinder service) {
    messageSender = new Messenger(service);
    refreshToken();
}

@Override
public void onServiceDisconnected(ComponentName arg) {
    serviceListener.onError(new Error("Service disconnected"));
    // We returned an error so there's no point in
    // keeping the binding open.
    mAuthActivity.unbindService(TokenRefreshServiceConnection.this);
}

All three methods say, in the warning, that the method must override a superclass method. I have not modified the code at all yet. I checked that Eclipse recognizes the types as the same ones in the respective superclasses, and I have tried pressing control-shift-o to organize the imports, which was a fix suggested in this answer for a similar problem.

These overrides are part of the SDK, not any separate project. I set up the project to use Android SDK 2.2 as was shown on Facebook’s instructions, and 4.0.3, which should be, theoretically, compatible with all previous versions. I have yet to get Facebook’s own code to work. As a side note, is there a jar I can use instead? It would make this much easier.

Guessing your Project Properties -> Java Compiler Compiler compliance level is set to 1.5, not 1.6 (or higher).

Change this.
