在集成测试过程中遇到LinearAlloc溢出

Question

这是一个为期3-4年的Android项目，运行在5.4.1级。集成测试是与莫基托，浓缩咖啡和匕首。

我遇到了一个问题，当我们向项目中添加一个Pendo库时，依赖项作为标准添加到Gradle中。一切运行良好，除非我们尝试运行集成测试(~2000)，否则这些测试都是用Spoon以碎片的方式运行的。

在集成测试的一半左右，每次在随机测试中，我们都会遇到一个本机崩溃，由于LinearAlloc超出了容量，导致测试无法运行。孤立地运行这些测试，或者在本地的类中运行，它们通过时没有问题，并且已经稳定了很长一段时间。

我把整个应用程序带回到了已知的好版本，只添加了Pendo依赖项，这导致了同样的问题，但是我不认为这是由于Pendo，因为我通过回到已知的好构建(在这个时候再次测试了理智)并添加了一个随机的新依赖，这导致了同样的问题。

据我所知，这可能与Android的方法限制有关。我应该说我们正在使用multidex来分解这个应用程序。还在使用Proguard和minify。

这里的部分问题是，我真的不知道该看什么来找出导致这种溢出的原因。在测试运行的日志之后，似乎没有什么问题，除了一些垃圾收集(我猜这意味着某个地方有漏洞)。我不确定这个问题是否是因为一些潜在的漏洞，而新的库正在把一些东西推到边缘，或者是我不知道的安卓系统中是否存在某种依赖限制，或者其他方式来分解文件，这样我们就不会让LinearAlloc填满。

从阅读中，我知道LinearAlloc的极限是在安卓5上增加的，我们在设备上(安卓10)和低于这个(安卓4)的设备上都有问题，而且自2017年以来我没有看到很多关于这个问题的讨论，所以我觉得我遗漏了一些显而易见的东西，或者在这个项目中出现了一些错误的配置，因为它是在那之前设置的。

任何帮助都会很感激的。我已经在下面抛出了一个压缩版本的gradle文件

好的，这是一个有趣的问题，如果任何人遇到类似的问题，就把这个放在一边。

在这种情况下，我们发出的错误信息似乎是相当误导的。帮助诊断这类错误的一个好方法是查看坠机留下的墓碑，有关更多信息，请参见https://source.android.com/devices/tech/debug/native-crash。

在这种情况下，pro卫兵是我们的敌人，它似乎在测试代码上执行某种类型的优化，导致变量被错误地分配，并通过添加-optimizations *other optimizations*,!code/allocation/variable来解决--这可能不适用于您的特定情况，但可能尝试配置proguard以不进行优化，看看这是否有帮助:D。
