Whenever you do read/write operation using StreamReader/StreamWriter classes, please make sure you are calling ioStream.close() inside first try{} block. Something like this:

    AssetManager AssetManager = mContext.getAssets();
    try {
        InputStream is = AssetManager.open("sample.json");
        int size = is.available();
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();
    } catch (Exception ex) {
        ex.printStackTrace();
    }

Even If you have another try{} block under catch/finally {} block still it will throw above exception.

instead you can assign ioStream = null in catch/finally {} block.

catch (Exception ex) {
  // If ioStream object is outside the try block
  ioStream = null;
}
