Why do you need a log?

Whenever you run into an issue and try to report it you must have seen the request from the support or development teams to provide a log or a logcat.

A log helps the development team debug the issue and find out the resolution.

To generate a logcat you would need to enable adb on your phone as well as your PC.

What is adb?

adb stands for Android Debug Bridge. adb is a versatile command-line tool that lets you communicate with a device. The adb command facilitates a variety of device actions, such as installing and debugging of apps.

To enable adb

  1. On your phone

    • Enable Developer options in Settings (Settings > About phone > Tap Build number 7 times).
    • Enable Android debug (Settings > System > Developer options > Android debugging).

  2. On your computer,

    • Install adb on your PC.

    • There could be issues here with the device driver or the OS type. You can find details on how to install adb here.

    • Connect your device to your computer.

    • Detect your device by typing the below command at the command prompt:

      $ adb devices

    • You would have to accept an authorization on your phone. A pop up like this will appear.
  • Check the option Always allow from this computer and click Ok.
  • Check that your device is being detected by adb.
  • Once you accept the authorization shown above you will see the display on you screen like this.
  • If you do not accept the message will say that the device is unauthorized.

Generate a bug report using adb

  • Try to reproduce the error. For e.g if Music app is crashing then run it again. The app you are
    facing an issue with will crash.

  • Now Run this command at the command prompt / console:

    $ adb logcat -d > logcat.txt

  • This will create a file called logcat.txt in the current folder.

  • Check the file for any personal data. You can either scroll the log file or do a search. Remember the file can be quite large.

  • Once you have the logcat file please share it with the development team as an attachment to the Gitlab error .

Additionally, the radio buffer can be viewed or stored with logcat. If needed or requested, type the below command:

`adb logcat -db radio > radio.txt`

Next save it as radio.txt and share with the development team or on Gitlab.

Capture a bug report from a device

  • Pre requisites for sending this report from the device:
    • To be able to attach the bug report once it is created, there should be an email account configured on the phone.

    • Enable Developer options on the device. If Developer options has not been enabled on your device check this guide.

    • In Developer options, tap Bug report.
  • Select the type of bug report you want and tap Report. Two options will be displayed - Interactive and Full Report. Check with the developers what type of report they require.

  • After a moment you get a notification that the bug report is ready.

  • Swipe down on the notifications to share the bug report you just created.

  • You would see a warning regarding the information in your log. Check the logs for any personal information before sharing.
  • Once you have accepted the above warning you will be shown the option to share the information. Here we are assuming you will go ahead with the email option.
  • The below screenshot is how the email will show up. Add the email ID of the person or Murena team you want to send the log to.
