Why does my game crash on Android?

Because of Android's extreme device fragmentation, device-specific issues, version differences, out-of-memory on low-RAM devices, and ANRs from main-thread blocks, cause crashes you cannot reproduce on your device. Android has thousands of device models with different chipsets, GPUs, RAM, and manufacturer OS customizations, plus many Android versions. Your game runs across all of them but you test on a few, so crashes happen on the combinations you did not test: device-specific issues (a model, chipset, or manufacturer quirk triggering a crash), Android-version differences, out-of-memory (budget and older devices have limited RAM, a leading crash cause), and ANRs (the main thread blocked too long, a distinct Android failure). These are invisible on your test device. Bugnet captures Android crashes with device, version, and memory context plus stack traces, so you see which devices and versions crash and why (device, version, memory, or ANR), revealing the Android-specific cause so you can fix it and verify per version.

What is an ANR and how do I fix it?

An ANR (Application Not Responding) is when your app's main thread is blocked too long and Android kills it, fix it by moving heavy work off the main thread so it stays responsive. On Android, the main thread must stay responsive (handling input and updates), and if it is blocked for too long (a few seconds), Android shows an ANR and may kill the app. So an ANR is a freeze-then-kill from the main thread being stuck, distinct from a crash (a fatal error). Common causes of the block: heavy work on the main thread (computation, loading, processing), synchronous I/O on the main thread (file, database, or network operations), long lifecycle-callback work, and lock contention. The fix is keeping the main thread responsive by moving heavy/blocking work off it (to background threads or async), so it never blocks long enough to trigger an ANR. Bugnet captures ANRs and crashes from Android with context (what the app was doing), so you can see your ANRs, identify what is blocking the main thread, move that work off it, and verify per version that ANRs dropped on the affected devices.

How do I handle Android device fragmentation?

Capture crashes from real devices to see the fragmentation's effects, fix the high-impact device-specific issues, test a representative range, and use scalable settings, since you cannot own every device, field capture is how you handle it. Android fragmentation makes testing every device impossible. Capture crashes from real players' devices with device, version, and memory context (revealing which of the many devices crash and why), fix the high-impact device-specific issues first (rank by affected players, so you fix the crashes hitting the most players, like out-of-memory on low-RAM devices), test a representative range (popular models, low-end devices, major OS versions), and use scalable settings (so the game adapts to device capability). Bugnet captures Android crashes from real devices with device, version, and memory context and ranks by impact, so the crashes across the fragmentation become visible and prioritized, letting you find and fix the device-specific issues hitting the most players and verify per version, handling Android's fragmentation by making its invisible, device-specific crashes visible and fixable.

Ways to Fix Android Crashes

Quick answer: Capture crashes with device, Android version, and memory context, identify the pattern (device-specific, version-specific, out-of-memory, or ANR), fix the cause, and verify per version, Android's fragmentation causes crashes invisible on your device.

Android's extreme fragmentation makes it crash in ways you cannot reproduce on your device. Here are the best ways to fix Android crashes.

Capture Crashes With Device and Version Context

Fix Android crashes by capturing them with device, Android version, and memory context, since crashes happen across countless device models and OS versions you do not have. The captured context is the only way to see what crashes across Android's range.

Bugnet captures crashes from real Android devices with device, version, and memory context plus stack traces, so you see which of the many devices and OS versions crash, the basis for fixing them.

Identify the Android-Specific Pattern

Fix Android crashes by reading the pattern, do they cluster on specific devices (a manufacturer or chipset issue), Android versions (an OS-version difference), low-memory devices (out-of-memory), or show as ANRs (a main-thread block)? The pattern points at the cause.

Bugnet groups Android crashes by signature with device, version, and memory context, so the pattern (device, version, memory, or ANR) is visible, revealing the right Android-specific cause to fix.

Fix the Cause and Verify on Android

Fix Android crashes by addressing the cause the pattern revealed, handle the device/manufacturer issue, support the Android version, reduce memory for low-RAM devices, or unblock the main thread for ANRs, then verify per version on the affected devices.

Bugnet tracks crashes per version with device context, so after fixing you can confirm the crashes stopped on the affected devices and Android versions, verifying the fix across Android's fragmentation.

Fix Android crashes by capturing them with device, version, and memory context, identifying the pattern (device-specific, version-specific, out-of-memory, or ANR), fixing the cause, and verifying per version.
