Android Bugreport Metrics
HexDroid analyzes uploaded Android bug reports and extract relevant metrics.
These metrics enabling users to generate custom graphs, track performance trends over time, and compare multiple data
points.
By combining and correlating various metrics, HexDroid facilitates "sensor fusion,"
offering a comprehensive view to help users better understand system behavior, identify potential issues, and assess the
overall impact of different factors.
Each metric derived from bugreport will contain the following additional properties:
| Property | Description |
|---|
build | eg: AP2A.240805.005 |
fingerprint | eg: google/cheetah/cheetah:14/AP2A.240805.005/12025142:user/release-keys |
bootloader | eg: cloudripper-14.5-11677884 |
androidSdkVersion | eg: 34 |
ANRs (Application Not Responding)
| Metric ID | Description | Properties |
|---|
anr.count | Total number of ANRs (per package) found in bugreport | package |
Tombstones (Native Crashes)
| Metric ID | Description | Properties |
|---|
tombstone.count | Total number of Tombstones (Native Crashes) (per package) found in bugreport | package, abi |
SELinux Violations
| Metric ID | Description |
|---|
selinux.count | Total number of SE Linux violation found in bugreport |
| Metric ID | Description | Properties |
|---|
gfx.jankyFrames | The total number of frames that were rendered slower than the frame rate, causing noticeable stuttering or lag. | package |
gfx.jankMissedVsync | Frames that missed the vsync, leading to visual tearing or stuttering. | package |
gfx.jankHighInputLatency | Frames affected by high input latency, making the app feel unresponsive to user interactions. | package |
gfx.jankSlowUiThread | Frames delayed due to slow execution on the UI thread, often because of heavy processing or blocking tasks. | package |
gfx.jankSlowBitmapUpload | Frames delayed due to slow uploading of bitmap data to the GPU, impacting smoothness. | package |
gfx.jankSlowIssueCommands | Frames delayed by slow issuance of rendering commands to the GPU, causing visual lag. | package |
gfx.jankFrameDeadlineMissed | Frames that failed to meet the rendering deadline, leading to skipped or delayed frames. | package |
