Automate Android Crash Debugging with Bugly: Mapping Upload & Custom Logs

1. Use Bugly to automatically restore stack traces

When first integrating Bugly, the obfuscated Java stack traces were hard to read; manually uploading mapping files allowed Bugly to de‑obfuscate them. By using the Android Studio Symbol Table plugin, mapping files can be uploaded automatically in two steps.

Step 1: Add the Bugly Gradle dependency in the project‑level build.gradle.

Step 2: Apply the plugin and configure appId, appKey, execute, and upload in the module‑level build.gradle, then sync and rebuild. The plugin will download from jCenter and upload the mapping file automatically.

2. Quickly locate the exact source line of an exception

Release builds often differ from development builds, and ant scripts may modify source code (e.g., removing logs), causing line numbers in the uploaded crash to mismatch the current source. To solve this, the team archives the source code of each build in a bin directory. When a crash occurs, the corresponding archived source can be downloaded to pinpoint the exact line.

3. Reconstruct user operation paths with custom logs

By encoding key business‑logic nodes and reporting them through Bugly’s custom‑log feature, the team can view the sequence of operations that led to an exception. A custom‑log parsing platform then restores the operation path, making it easier to reproduce and fix the bug.
