using openFileOutput() in a class. (not an activity)

Question

my Activity class calls to another non-activity class and when i try to use openFileOutput, my IDE tells me that openFileOutput is undefined. please help:

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.*;

import android.util.Log;
import android.content.Context;

public class testFile(){

Context fileContext;

public testFile(Context fileContext){
    this.fileContext = fileContext;
}

public void writeFile(){
    try{
            FileOutputStream os = fileContext.getApplicationContext().openFileOutput(fileLoc, Context.MODE_PRIVATE);
        os.write(inventoryHeap.getBytes()); // writes the bytes
        os.close();
        System.out.println("Created file\n");
    }catch(IOException e){
        System.out.print("Write Exception\n");
    }
}
}

Solution 1

I deleted my answer from before, since I was wrong, the problem I see is that you add () to the class declaration: public class testFile(){. it should be public class testFile{. That's all.

Solution 2

You've already got a Context.

FileOutputStream os = fileContext.openFileOutput(fileLoc, Context.MODE_PRIVATE);
