Logging support for Android devices

Build requirements: Android SDK 2.3+ Runtime requirements: Android OS 2.3+

Setup

Set up an account with Logentries at https://logentries.com/, and create a logfile, by clicking + Add New button and selecting the Manual Configuration Option at the bottom. Select Token TCP as the source type and copy the Token UUID printed in green.

Next, download the library jar file here and place it in the /lib folder of your Android project.

Add the android.permission.INTERNET to the project manifest file.

Use

In the desired Activity class, import com.logentries.android.AndroidLogger

To create an instance of the Logger object in an Activity class: AndroidLogger logger = AndroidLogger.getLogger(Context context, String token); Where

  • context: for example, if in an Activity class, use getApplicationContext(), or if in an Application class, use getBaseContext().

  • token: is the Token UUID we copied earlier which represents the logfile on Logentries

Log events are created using the following methods of the AndroidLogger class, which differ only in terms of the severity level they report:

  • severe, debug, info, config, fine, finer, finest, verbose

Eg: logger.error("Log Event Contents"); creates the log Sat Jul 30 16:04:36 GMT+00:00 2011, severity=ERROR, Log Event Contents.

Each method corresponds to those used in android.util.Log and java.util.logging.Logger.

Logging Device IP

Alternative Constructor which allows a User to log the devices IP:

To create an instance of the Logger object in an Activity class:

AndroidLogger logger = AndroidLogger.getLogger(Context context, String token, boolean logIp);

Where

  • context: for example, if in an Activity class, use getApplicationContext(), or if in an Application class, use getBaseContext().

  • token: is the Token UUID we copied earlier which represents the logfile on Logentries

  • logIp: Is an option to log the users IP address. The IP logged will be the public if it is available otherwise it is gotten via the Host Address.

DataHub Support

Additional constructors for AndroidLogger have been created for use with Logentries DataHub. There are two additional constructors added, one with a customID and one without customID. They are respectively:

  AndroidLogger logger = AndroidLogger.getLogger(Context context, String datahub_address, int datahub_port);

and

 AndroidLogger logger = AndroidLogger.getLogger(Context context, String datahub_address, int datahub_port, String customID);
  • context: for example, if in an Activity class, use getApplicationContext(), or if in an Application class, use getBaseContext().

  • datahub_address: is a String of the IP Address of your DataHub machine.

  • datahub_port: is an int of the port number of your incoming connection on your DataHub machine. The default is port 10000, but this can be changed to any port by altering the /etc/leproxy/leproxyLocal.config file on your DataHub machine and restarting the leproxy daemon using "sudo service leproxy restart".

  • customID - is a String of the customID you may wish to add to your log events. This is different from the deviceID which is now automatically set and entered into your logs.

The logger will now add the android deviceID as a Key Value Pair in your logs. This requires API 9 and above.

NOTE: You cannot use both Token-based and DataHub-based AndroidLogger constructors in your application. You can only use one or the other.
