Android java.lang.IllegalArgumentException:无法找到本机库:main [英] Android java.lang.IllegalArgumentException: Unable to find native library: main

问题描述

今天，我找到了一些项目，这些项目演示了android ndk编程.这是此项目

Today I found some projects, which demonstrates android ndk programming. Here is this projects

我正在尝试启动项目 DroidBlaster .我已经编译了所有本机库，没有错误.结果如下:

I'm trying to start project DroidBlaster. I have compiled all native libraries without errors. Here is result:

我只是做了一些小改动:

I just made some small changes:

1).已添加到AndroidManifest.xml选项android:hasCode="true"

1). Added to application tag in AndroidManifest.xml option android:hasCode="true"

2).我从本地活动扩展，并在活动的static块中加载了所有库.

2). I extended from native activity and load all libraries in static block of activity.

我这样做是因为，如果不进行此更改，Android将无法找到在AndroidManifest.xml (此处为作者的代码)中声明的库libdroidblaster.so :

I did this, because, without this changes, android can't find library libdroidblaster.so which was declared in AndroidManifest.xml(Here is code from author):

<activity
            android:name="android.app.NativeActivity"
            android:label="@string/app_name" >
            <meta-data
                android:name="android.app.lib_name"
                android:value="droidblaster" />

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

现在我的AndroidManifest.xml看起来像:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.demo.droidblaster"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="22" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        android:hasCode="true">

        <activity android:name=".MainActivity"
                  android:label="@string/app_name"
                  android:configChanges="orientation|keyboardHidden">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name="android.app.NativeActivity"
            android:label="@string/app_name" >
            <meta-data
                android:name="android.app.lib_name"
                android:value="droidblaster" />
        </activity>
    </application>

    <uses-permission android:name="android.permission.RECORD_AUDIO" />

</manifest>

还有我的新活动:

public class MainActivity extends NativeActivity {
    static {
        System.loadLibrary("irrlicht");
        System.loadLibrary("droidblaster");
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

当我尝试启动应用程序时，出现此错误:

When I try to start app, I get this error:

因此，原因是:

java.lang.IllegalArgumentException: Unable to find native library: main

我找不到解决此问题的解决方案.

I can't find a solution to fix this problem.

有人知道如何解决吗?
