Android版的System.loadLibrary摊位加载本地库 [英] Android System.loadLibrary stalls while loading native library

问题描述

我有一个相当大的共享库文件（= 12megabytes）不包含任何JNI code任何责任。

I have a rather large shared library file (= 12megabytes) which does not contain any JNI code whatsoever.

致电时的System.loadLibrary（SOME_FILE）方法的从不返回并不会产生相关的输出。此外，Windows任务管理器报告该仿真器实例未占用所有的CPU资源。

When calling System.loadLibrary("some_file") the method never returns and no relevant output is generated. Also, Windows Taskmanager reports that the emulator instance is not hogging all the CPU power.

我有以下code类：

static 
{
    System.out.println("Trying");
    System.loadLibrary("some_file");
    System.out.println("Works");
}

下面是从LogCat中给出的输出：

Here is the output given from LogCat:

I/System.out(534): Trying
D/dalvikvm(534): Trying to load lib /data/data/app/lib/libsome_file.so 0x40643c20

如果我上传使用该库libsome_file.so本地测试应用程序和模拟器shell中运行这一点，那么应用程序的工作。

If I upload a native test application that uses the library libsome_file.so and run this from the emulator shell, then the application works.

有没有进行调试的System.loadLibrary正在做或任何人都不会有一些提示，为什么的System.loadLibrary一去不复返？法

Is there any method to debug what System.loadLibrary is doing or does anyone have some hints why System.loadLibrary might never return?

推荐答案

我找到了解决自己的问题。我没有使用任何额外的调试工具，但离开了库加载时所运行一些code。具体code绞刑，使得悬挂的System.loadLibrary以及

I found the solution to the problem myself. I did not use any additional debug tools, but left out some code that was run when the library loaded. The particular code hanged, making System.loadLibrary hang as well.
