1. App crashes when it starts, because I make a error to set TextView.textcolor to a String resource Value, it should be a drawable resource value

<?xml version="1.0" encoding="utf-8"?> <resources> <string name="mainbtnlogin">Login</string> <drawable name="general_back_color">#FFFFFF</drawable> //this is right to assign to a color type variable <string name="general_text_color">#000000</string> //this is wrong to assign to a color type variable <drawable name="general_linkable_color">#0000FF</drawable> <string name="value_zero">0</string> </resources> |
2. I wrote a function which used Context of the activity. But when I finished coding, eclipse gave an error message. After a about 1 hour research, I finally found I wrote the function in the subclass of the activity. After moving the function to the main class, it works.
