PID：15208 java.lang.UnsatisfiedLinkError：dalvik.system.PathClassLoader

Question

I have just started learning cocos2d-x-3.11.1 in android studio (trying to compile with native C++ language) and I am getting this following error and a message on my phone "Unfortunately libcocos2dx has stopped"

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.granjur.org-1/base.apk"],nativeLibraryDirectories=[/data/app/com.granjur.org-1/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "libMyGame.so"

I have configured NDK , SDK and the ANT folders correctly from command line. I've been stuck with this from last two days!

AndroidManifest.xml

<uses-feature android:glEsVersion="0x00020000" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher">

        <!-- Tell Cocos2dxActivity the name of our .so -->
        <meta-data android:name="android.app.lib_name"
                   android:value="MyGame" />

        <activity
            android:name="org.cocos2dx.cpp.AppActivity"
            android:screenOrientation="landscape"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

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

</manifest>

Any help would be highly appreciated! Thank you!

Answer 1

在游戏目录中运行此命令以编译源一次：

cocos compile -p android --android-studio

Answer 2

Finally I have a genuine solution to the above problem for users working on android studio project of cocos2dx 3.8.1 above.

Just add this line in Application.mk :)

 APP_ABI := armeabi-v7a

Sample Application.mk file :

APP_STL := gnustl_static

APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -std=c++11 -fsigned-char
APP_LDFLAGS := -latomic


ifeq ($(NDK_DEBUG),1)
  APP_CPPFLAGS += -DCOCOS2D_DEBUG=1
  APP_OPTIM := debug
  APP_ABI := armeabi-v7a
else
  APP_CPPFLAGS += -DNDEBUG
  APP_OPTIM := release
  APP_ABI := armeabi-v7a

endif

The main problem was the device architecture compatibility with your application. We need to give exclusive support to devices with ARM architecture armeabi-v7a when running proj.android-studio.

Hope this will help many other like me.
