android - 当我的代码没有出现在堆栈上时，如何解释 ANR traces.txt？

转载作者：塔克拉玛干更新时间：2023-11-01 21:47:10

我正在尝试在我的 Android 应用程序中调试持续性 ANR(“应用程序无响应”)。

我已经阅读了这些主题:

最重要的消息是使用 StrictMode ，我会做的。

但是，我仍然想解释一下我反复看到的 ANR 堆栈的原因。首先，我没有看到任何主线程——而是在主“组”中看到许多线程，包括一个名为“waitForActivityStart”的线程。

在所有线程上我都看不到我的代码，所以我很困惑为什么我自己的代码会导致这种 ANR。我从我安装的库中看到的唯一代码是 Google Analytics (GA)，您可以看到标题为“GAThread”的代码。那会是罪魁祸首吗？如果是这样，有人可以解释我如何从这份报告中推断出这一点吗？

这是我在运行 4.2.2 的 Nexus 7 上使用 ADB 提取的 traces.txt 的输出

最佳答案

基本调查步骤

找到“等待锁定”
- 您可以找到监控状态“Binder Thread #15”prio=5 tid=75 MONITOR
- 如果找到“waiting to lock”就幸运了
- 示例:WAITING锁定 threadid=74 持有的 <0xblahblah>(一个 com.foo.A)
您可以注意到“tid=74”现在持有一个任务。所以去tid=74
tid=74 可能是 SUSPENDED 状态!找主要原因!跟踪并不总是包含“等待锁定”。在这种情况下，很难找到主要原因。
