LogViewer 💻📝🔍

LogViewer is a simple tool to help you analyze Android logs. It allows you to analyze multiple log files at once and create (and apply) different filters on this set of log files showing a single filtered output differentiating each filter by a different color (defined by you).

Check out more details on https://tibagni.github.io/LogViewer/.

• 🔍 Analyze multiple log files at once
• 🎨 Create and apply different filters on the set of log files, showing a single filtered output differentiating each filter by a different color (defined by you)
• 🔎 Search across all open filter groups with a global Find dialog (Ctrl+Shift+F)
• 🌗 Modern UI with Light and Dark themes
• 🤖 Read bugreport information such as system properties, application packages, hidden system packages, carrier config, subscriptions etc.
• 📝 Note the important log entries in my log view
• ⏱️ Limit all logs by ignoring everything before or after a selected timestamp
• 🛠️ Adjust the log viewer preferences to match your workflow

• Java 8 or later (tested on Java 8, 11, 17, and 21)
• Gradle (optional, wrapper ./gradlew is included)

To get started with LogViewer, follow these steps:

1. Clone this repository and open it in IntelliJ IDEA or any other Java development environment of your choice.
2. Build the application by running ./gradlew build on the command line.
3. Create the standalone executable JAR by running ./gradlew shadowJar.
4. Run the application:

   java -jar build/libs/LogViewer-*-all.jar

   (Or run directly from IntelliJ IDEA).
5. Use the UI to analyze log files, applying filters and more...

To create a JAR file for the project, you can use the shadowJar task provided by Gradle. Run ./gradlew shadowJar on the command line to create a JAR file in the build/libs directory. The JAR file will be named LogViewer-{version}-all.jar, where {version} is the current version of the project.

To increase the app version, change it in app.properties. This file is located in src/main/resources/properties/app.properties and there is a symbolic link for it on the root folder to make it easier to access. You can use any text editor to edit this file, or you can use IntelliJ IDEA to open it and edit it directly from within the IDE.

You can run tests on IntelliJ by right-clicking on the test folder (it is under src/test) and selecting "Run 'All Tests'". Alternatively, you can run ./gradlew test on the command line to run all tests.

To create a Pull Request instead of pushing directly to master, use the bundled helper script (requires GitHub CLI):

1. Commit your changes locally.
2. Run:

   ./pr-workflow.sh <feature-branch-name>

   This will create a new branch from your commits, push it to GitHub, automatically open a PR targeting master using your commit messages for the title and description, and switch back to your local master.

Deployments are handled via the Release Deploy GitHub Action:

1. Run the version increment helper script:

   ./inc-ver-workflow.sh <new-version>
   # Example: ./inc-ver-workflow.sh 2.8

   This validates the new version number, updates app.properties, creates the commit and tag, and pushes them to GitHub.
2. On GitHub, navigate to the Actions tab ➔ Release Deploy.
3. Click Run workflow, enter the tag name (e.g., 2.8), and submit. The workflow will automatically build the standalone fat JAR, generate release notes, and publish the GitHub Release with the binary attached.
