Creates an ObjectOutputStream that writes to the specified OutputStream.

Usage

From source file:Main.java

/**
 * Get a stream that can be used for serialization
 * /* w w w  . j a v a2s  . c om*/
 * @param context
 *            We'll write our data to this context private dir
 * @param name
 * @return
 * @throws IOException
 */
public static ObjectOutputStream writeObjectStream(Context context, String name) throws IOException {
    OutputStream s = context.openFileOutput(name, Context.MODE_PRIVATE);

    // I'd prefer to not overwrite the old file, but Context doesn't offer a
    // fileRename option
    return new ObjectOutputStream(s);
