Android 如何从相机拍摄多幅图像并保存到阵列中，然后转换64Base

这是我的职责

我必须动态捕获多个图像，并在运行时显示在图像视图中，保存到数组中，然后数组编码到Base64，然后发布到json

    private void setPic() {
    // Get the dimensions of the View
    int targetW = account_image.getWidth();
    int targetH = account_image.getHeight();

    // Get the dimensions of the bitmap
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(String.valueOf(mCurrentPhotoPath), bmOptions);
    int photoW = bmOptions.outWidth;
    int photoH = bmOptions.outHeight;

    // Determine how much to scale down the image
    int scaleFactor = Math.min(photoW / targetW, photoH / targetH);

    // Decode the image file into a Bitmap sized to fill the View
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inSampleSize = scaleFactor;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions);

    account_image.setImageBitmap(bitmap);
}

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);

    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();



    Log.e("Getpath", "Cool" + mCurrentPhotoPath);
    return image;
}

请指导我如何完成工作

您好，欢迎来到StackOverflow。请花些时间阅读帮助页面，特别是命名和的部分。更重要的是，请阅读。您可能还想了解。那么，还缺少很多代码。甚至没有定义数组。
