Question

I got an Eclipse project source code(I was told that on Android Studio, maybe they just confused), and I start to migrating the code to android studio refers to

Answer 1

That's a problem related to BOM (Byte Order Mark) character. Byte Order Mark BOM is a Unicode character used for defining a text file byte order and comes in the start of the file. Eclipse doesn't allow this character at the start of your file, so you must delete it. For this purpose, use a rich text editor, such as Notepad++, and save the file with encoding "UTF-8 without BOM." That should remove the problem.

Answer 2

At bottom right of the project change file encoding UTF-8 to UTF-16.

1. A new dialog will get open. Select convert it and run it.
2. It will give you some errors then again change UTF-16 to UTF-8.
3. Convert it and run the project. This time your project will run successfully.

Answer 3

On lower-right corner, you can set the file encoding. Select another option than UTF-8

If a popup appear, choose the option Convert.
