Dear @EDWIN_JAMES,
as @Patryk_F has already said, your Arduino code is missing the correct string terminator (i.e. the ASCII character "linefeed", 0x0A, or decimal 10). To obtain this your last sending to the app via BT shall be made by using a hc05.println(); and not just with a .print();
You can refer to very detailed instructions by reading the FAQ from @ABG :
Moreover, to be sure that your Arduino is sending data correctly, you could, at the beginning, use a ready made app, like Serial Bluetooth Terminal that you can download free from Google Appstore. Once you are sure that the communication from Arduino to your Android device is working fine, then you can go on with your app. Last, but not least, remember that you shall cross Tx and Rx piins between HC05 and Arduino CPU board.
Best wishes
