Replace resources in whole application

[ozodrukh]

Have someone experience in replacing Resources in whole application, i need to intercept getDrawable method everywhere

Testing on Genymotion, Android 4.1.1

i need some ideas how to work around

1. Approach to wrap context when attachBaseContext method called, failed. When inflating views it doesn't works :(
2. I found really strange behavior that the original(android) views and custom views are getting different types of Context. Cause i made efforts to set background via XML on ImageButton and get Exception, but when i create custom view extended from ImageButton it worked
   update on approach 2
   hmm, looks like if i define background as an attribute it falls, if do it by code it works

i found what is going on after all, the views calls TypedArray#getDrawable method

    public Drawable getDrawable(int index) {
        if (mRecycled) {
            throw new RuntimeException("Cannot make calls to a recycled instance!");
        }

        final TypedValue value = mValue;
        if (getValueAt(index*AssetManager.STYLE_NUM_ENTRIES, value)) {
            if (value.type == TypedValue.TYPE_ATTRIBUTE) {
                throw new RuntimeException("Failed to resolve attribute at index " + index);
            }
            return mResources.loadDrawable(value, value.resourceId, mTheme);
        }
        return null;
    }

Now i need to think how to replace loadDrawable method 😞

New plan, going to replace LayoutInflater with custom one and create custom attributes like Calligraphy did

OK, i think it is unnecessary, because the library like Decor can solve this problem
