7,169 PointsUsing fileToWrite.exists() method of file class doesn't work. Why?
I'm applying the check right before the method copyResult(in, out) is being called. What am I missing?
import java.io.InputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
public class FileUtilities {
public static boolean copyResult;
public static void saveAssetImage(Context context, String assetName) {
File fileToWrite = new File(context.getFilesDir(), assetName);
AssetManager assetManager = context.getAssets();
try {
InputStream in = assetManager.open(assetName);
FileOutputStream out = new FileOutputStream(fileToWrite);
if(fileToWrite.exists())
copyResult = copyFile(in, out);
} catch(FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private static boolean copyFile(InputStream in, FileOutputStream out) {
// Copy magic intentionally omitted
return true;
}
}

155,055 PointsYou're so close! You only want the file to be written if it does not already exist. Your 16th line is what needs adjusting... you're almost there.
Example answer:
import java.io.InputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
public class FileUtilities {
public static boolean copyResult;
public static void saveAssetImage(Context context, String assetName) {
File fileToWrite = new File(context.getFilesDir(), assetName);
AssetManager assetManager = context.getAssets();
try {
InputStream in = assetManager.open(assetName);
FileOutputStream out = new FileOutputStream(fileToWrite);
if(fileToWrite.exists() == false)
copyResult = copyFile(in, out);
} catch(FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private static boolean copyFile(InputStream in, FileOutputStream out) {
// Copy magic intentionally omitted
return true;
}
}
