//Android的Bitmap轉成Base64並存入資料庫的方法
 
 // 先把 bitmpa 轉成 byte
 ByteArrayOutputStream stream = new ByteArrayOutputStream();
 bmp.compress(Bitmap.CompressFormat.PNG, 100, stream );
 byte bytes[] = stream.toByteArray();
 // Android 2.2以上才有內建Base64，其他要自已找Libary或是用Blob存入SQLite
 String base64 = Base64.encodeToString(bytes, Base64.DEFAULT); // 把byte變成base64
 
 // 再來是轉回來, 把Base64變回bytes

# How do I test my APN push notification certificates (PEM key)?
# https://www.pubnub.com/knowledge-base/discussion/234/how-do-i-test-my-pem-key
# You can test your PEM key using the following command, which should hang if successful until you press enter:
# openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert pnpush.pem -key pnpush.pem
# The above tests the PEM Key in sandbox mode. For production mode, use the following command:
# openssl s_client -connect gateway.push.apple.com:2195 -cert pnpush.pem -key pnpush.pem
# You can also test your PEM Key by running the Python script below using the script below. The usage would be:
# python push_debug.py <CERT_PATH> <DEVICE_TOKEN>
