【问题描述】：

我正在尝试将 openwhispersystems 中的 curve25519-java 集成到我的 Android 应用程序中，并使用 API 23 (Marshmallow) 对其进行编译。当使用非本机代码时，我得到这个运行时异常：

java.lang.VerifyError: Rejecting class org.whispersystems.curve25519.java.fe_mul because it failed compile-time verification (declaration of 'org.whispersystems.curve25519.java.fe_mul' appears in /data/app/com.fenritz.safecam-1/base.apk)

任何想法为什么它被拒绝以及我该如何解决这个问题。

    【解决方案1】：

    由于单个方法中的变量太多而引发此异常。只需将其分为两种方法即可解决问题。这是修复：

    package org.whispersystems.curve25519.java;

public class fe_mul {

//CONVERT #include "fe.h"
//CONVERT #include "long.h"

/*
h = f * g
Can overlap h with f or g.

Preconditions:
   |f| bounded by 1.65*2^26,1.65*2^25,1.65*2^26,1.65*2^25,etc.
   |g| bounded by 1.65*2^26,1.65*2^25,1.65*2^26,1.65*2^25,etc.

Postconditions:
   |h| bounded by 1.01*2^25,1.01*2^24,1.01*2^25,1.01*2^24,etc.
*/

/*
Notes on implementation strategy:

Using schoolbook multiplication.
Karatsuba would save a little in some cost models.

Most multiplications by 2 and 19 are 32-bit precomputations;
cheaper than 64-bit postcomputations.

There is one remaining multiplication by 19 in the carry chain;
one *19 precomputation can be merged into this,
but the resulting data flow is considerably less clean.

There are 12 carries below.
10 of them are 2-way parallelizable and vectorizable.
Can get away with 11 carries, but then data flow is much deeper.

With tighter constraints on inputs can squeeze carries into int32.

      【解决方案2】：

      嘿，亚历克斯，我认为这是您问题的解决方案。从同步块捕获异常在运行时失败，并出现以下异常：Rejecting class fr.inra.ar​​ttest.MyClass 因为它未能通过编译时验证。因此，请检查任何对同步的调用。您还可以从这个谷歌错误帖子中阅读更多关于这个问题的信息。 https://code.google.com/p/android/issues/detail?id=80961.

      希望对您有所帮助！

      【讨论】：

      • 我已经仔细检查了所有内容，在它的任何地方都没有同步块。所以问题可能依赖于其他地方。
