4,139 PointsThe following code is similar to what you just wrote. Modify this code to only write the file if it does not already exi
i keep getting errors but i dont see were im going wrong
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();
if(fileToWrite.exists()){
copyResult = copyFile(in, out);
}
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;
}
}

23,309 Pointshey, you are close. See, the error you get is "what is in and what is out?" Because they are not defined yet. You are copying a file if the file does not exist.
file.exists() returns true if it does exist, we only want to copy when it does NOT exist.
so (!file.exists()) copy the files.
This has to go underneath the input and output streams or else I have not yet defined what to copy. So check out the code I have below.
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;
}
}
