最近在封装sdk，里面的http请求使用了Google的Volley网络框架，在混淆打包以后，在其他工程里面运行报错，错误如下：

     Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/android/volley/toolbox/StringRequest;        at com.rdwl.rdsigmeshlib.http.RDHttp.<init>(Unknown Source:8)        at com.rdwl.rdsigmeshlib.http.RDHttp$Companion.getInstance(Unknown Source:15)        at com.rdwl.sigmeshdemo.activity.RegisterActivity.getCode(RegisterActivity.kt:44)        at java.lang.reflect.Method.invoke(Native Method)         at androidx.appcompat.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:397)         at android.view.View.performClick(View.java:6608)         at android.view.View.performClickInternal(View.java:6585)         at android.view.View.access$3100(View.java:785)         at android.view.View$PerformClick.run(View.java:25921)         at android.os.Handler.handleCallback(Handler.java:873)         at android.os.Handler.dispatchMessage(Handler.java:99)         at android.os.Looper.loop(Looper.java:201)         at android.app.ActivityThread.main(ActivityThread.java:6861)         at java.lang.reflect.Method.invoke(Native Method)         at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:547)         at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:873)      Caused by: java.lang.ClassNotFoundException: Didn't find class "com.android.volley.toolbox.StringRequest" on path: DexPathList[[zip file "/system/framework/org.apache.http.legacy.boot.jar", zip file "/data/app/com.rdwl.sigmeshdemo-sxexhkCXCIuH9KPUmyFfDg==/base.apk"],nativeLibraryDirectories=[/data/app/com.rdwl.sigmeshdemo-sxexhkCXCIuH9KPUmyFfDg==/lib/arm, /data/app/com.rdwl.sigmeshdemo-sxexhkCXCIuH9KPUmyFfDg==/base.apk!/lib/armeabi-v7a, /system/lib]]        at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:171)        at java.lang.ClassLoader.loadClass(ClassLoader.java:379)        at java.lang.ClassLoader.loadClass(ClassLoader.java:312)        at com.rdwl.rdsigmeshlib.http.RDHttp.<init>(Unknown Source:8)         at com.rdwl.rdsigmeshlib.http.RDHttp$Companion.getInstance(Unknown Source:15)         at com.rdwl.sigmeshdemo.activity.RegisterActivity.getCode(RegisterActivity.kt:44)         at java.lang.reflect.Method.invoke(Native Method)         at androidx.appcompat.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:397)         at android.view.View.performClick(View.java:6608)         at android.view.View.performClickInternal(View.java:6585)         at android.view.View.access$3100(View.java:785)         at android.view.View$PerformClick.run(View.java:25921)         at android.os.Handler.handleCallback(Handler.java:873)         at android.os.Handler.dispatchMessage(Handler.java:99)         at android.os.Looper.loop(Looper.java:201)         at android.app.ActivityThread.main(ActivityThread.java:6861)         at java.lang.reflect.Method.invoke(Native Method)         at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:547)         at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:873)

我的混淆规则比较直接，如下：

-keep class com.android.volley.** {*;}

我一直以为是我的混淆规则有问题，导致找不到这个相关类。搞了好久。。。

解决方法

比较蠢的解决方法，就是反正这个网络框架都是开源的，直接在项目里依赖完我的sdk后再依赖volley就好了。保证sdk中的volley依赖和项目中的版本号相同，这样就没问题了。

    // 我的sdk包    implementation files('libs/xxxx.aar')    // 依赖volley    implementation 'com.android.volley:volley:1.1.1'
