https://blog.csdn.net/Ltp_zy/. has found a solution. I don't know if you have used it. Please answer

for now.

Here's a workaround for the problem:

Add to your MainActivity: 

@Override
public AssetManager getAssets() {
    return getResources().getAssets();
}

we know what's causing this, but fixing it is non-trivial at this point in M development. The workaround should be ok though.
