问题描述
看似随机，Android Studio 安装的 apk 已损坏.它通常以 lambda 为中心(但每次都是不同的).我正在使用 Jack 编译和最新版本的所有内容(在最后列出).问题一直存在，直到我进行了干净的构建(然后一切正常).间歇性故障是一种新现象.使用 Jack 和 Java 8 特性一段时间以来，情况稳定.不幸的是，我无法确定在不稳定的故障开始之前发生了什么变化.
Seemingly at random, the apk that Android Studio installs is corrupted. It usually centers around lambdas (but it's a different one every time). I'm using Jack compilation and the latest version of everything (listed at the end). The problem persists until I do a clean build (and then everything's fine). The intermittent failures are a new phenomena. Things were stable with Jack and Java 8 features for awhile. Unfortunately, I can't pinpoint what changed before the flaky failures began.
示例代码:
private static final Ordering<Foo> ORDER_BY_FOO =
Ordering.natural().onResultOf(Foo::getId);
实际问题分配(在番石榴代码中):
Actual problem assignment (in Guava code):
ByFunctionOrdering(Function<F, ? extends T> function, Ordering<T> ordering) {
this.function = checkNotNull(function); // <-- Fails
[...]
class ByFunctionOrdering<F, T> extends Ordering<F> {
final Function<F, ? extends T> function;

- Android Studio/gradle 构建工具 2.2.2
- Gradle 2.14.1
- 构建工具版本 25.0.0
- sourceCompatibility/targetCompatibility JavaVersion.VERSION_1_8
- compileSdkVersion/targetSdkVersion 24
推荐答案
我认为这是构建工具 25.0.0 和 25.0.1 中的错误.恢复到 24.0.3 为我解决了这个问题.
I assume this is a bug in Build Tools 25.0.0 and 25.0.1. Reverting back to 24.0.3 fixed this issue for me.
更新更新到 com.android.tools.build:gradle:2.2.3 后，我度过了一个完整的工作日，使用 Build Tools v25.0.1 没有构建错误.
UPDATEAfter updating to com.android.tools.build:gradle:2.2.3, I had a full work-day without build errors with Build Tools v25.0.1.
