saving a string array to a file error

Question

How to format directory in android project folder as jvm can't see datass.txt or sometimes logcat says read only file...(i am putting datass.txt in main project root)

i am passing an array of strings and want to save it to a file datass.txt so i can retrieve data when internet is not connected

public void FileWrite(String[]  temp) throws IOException{
        File m = new File("datass.txt");
     final String[] descs = temp ;
     DataOutputStream out = new DataOutputStream(new
                BufferedOutputStream(
                  new FileOutputStream(m)));


     for (int i = 0; i < 31; i ++) {

            out.writeUTF(descs[i]);

        }
}

where is your file? If you are trying to access external files, you may need to add permissions. — kosa

You need to add File Writing Permission in your AndroidManiFest.xml file.

android.permission.WRITE_EXTERNAL_STORAGE

Please visit this link for various other permission set.

it seems that you could a Index out of bound exception i am not sure but to guard your self change the for loop header to this

for(int i =0; i < descs.length ; ++i)
