android - java.lang.IllegalArgumentException：无法加载本机库

Question

我在我的项目（原生活动）中使用纯原生 NDK。当我在 Android.mk 文件中添加带有我的 .so 的预构建静态库时，它工作正常。但是当我尝试链接 Prebuilt 共享库时，它显示以下异常：

03-27 16:42:09.982: E/AndroidRuntime(1275): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.irrlicht.example/android.app.NativeActivity}: java.lang.IllegalArgumentException: Unable to load native library: /data/app-lib/com.irrlicht.example-1/libHelloWorldMobile.so

这是我的 Android.mk 文件：

....

include $(CLEAR_VARS)
LOCAL_C_INCLUDES := /Users/karthi/Android/openal-soft-master/jni/OpenAL/include
LOCAL_MODULE := openal
LOCAL_SRC_FILES := /Users/karthi/Android/openal-soft-master/libs/armeabi/libopenal.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := HelloWorldMobile

LOCAL_CFLAGS := -D_IRR_ANDROID_PLATFORM_ -pipe -fno-exceptions -fno-rtti -fstrict-aliasing

LOCAL_C_INCLUDES := -I ../../include -I /Users/karthi/Android/openal-soft-master/jni/OpenAL/include

LOCAL_SRC_FILES := main.cpp android_tools.cpp game.cpp

LOCAL_LDLIBS := -lEGL -llog -lGLESv1_CM -lGLESv2 -lz -landroid

LOCAL_SHARED_LIBRARIES := openal

include $(BUILD_SHARED_LIBRARY)

在我的 AndroidManifest.xml 中：

<activity android:name="android.app.NativeActivity"
        android:label="HelloWorldMobile"
        android:launchMode="singleTask"
        android:configChanges="orientation|keyboardHidden"
        android:screenOrientation="landscape"
        android:clearTaskOnLaunch="true">
        <meta-data android:name="android.app.lib_name" android:value="HelloWorldMobile" />                            
        <intent-filter>
                    <action android:name="android.intent.action.MAIN" />

最后在 Application.mk 中：

APP_PLATFORM := android-18
APP_MODULES  := HelloWorldMobile
APP_STL      := stlport_static

我也尝试将最后一行替换为，

APP_STL := stlport_shared

我还应该怎么做才能将预构建的共享库与我的本机库链接？我在这里想念什么？任何帮助将不胜感激。

我通过创建 Native Activity 的子类并加载共享库解决了这个问题，如下所示：

package com.irrlicht.example;

public class MyActivity extends android.app.NativeActivity {

    static {
       System.loadLibrary("HelloWorldMobile");
       System.loadLibrary("openal");
    }
 }

在 AndroidManfest.xml 中，我包含MyActivity了而不是android.app.NativeActivity. 从这里得到这个解决方案。但是有没有办法在不使用 java 类的情况下完全解决这个问题？

1）在您的开放模块定义中，将 LOCAL_C_INCLUDES 替换为 LOCAL_EXPORT_C_INCLUDES 。前者对于预构建被忽略，后者会将值导出到依赖它的模块。这将允许您删除 HelloWorldMobile 定义中的相应路径。

2) 尝试将“openal”添加到您的 APP_MODULES 以确保它位于 libs/$ABI/ 下，否则该库可能永远不会成为您的 .apk 的一部分，从而阻止 HelloWorldMobile 的加载。
