The method getResources() is undefined for the type

在非activity的独立类（public class readwhatsapp）中调用getResources()时（InputStream is = getResources().openRawResource(R.raw.wa_contacts.db)），出现The method getResources() is undefined for the type

这是因为 getResources() 其实是contex中传递过去的，在非activity类中没有找到可以传递的cavas

解决：将activity类中contex传递过去就好了

创建全局变量，用于保存传递过来的context

private Context context;

调用InputStream is = context.getResources().openRawResource(R.raw.wa_contacts.db);就OK了
