4,630 PointsThe following code is similar to what you just wrote. Modify this code to only write the file if it does not already exi
What wrong with my code
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);
if (fileToWrite.exists() == false) { copyResult = copyFile(in, out); }
AssetManager assetManager = context.getAssets();
try {
InputStream in = assetManager.open(assetName);
FileOutputStream out = new FileOutputStream(fileToWrite);
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;
}
}

132,143 PointsYour actually pretty close, the fileToWrite variable needs to be moved inside try clause to be properly scoped:
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) {
AssetManager assetManager = context.getAssets();
try {
InputStream in = assetManager.open(assetName);
File fileToWrite = new File(context.getFilesDir(), 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;
}
}
