Android混淆

开启混淆

在app下面的build.gradle中将minifyEnable设置成true

buildTypes {
        release {
            minifyEnabled true//混淆打包
            shrinkResources true//去掉不用资源
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
    }

填写混淆文件

在proguard-rules.pro中填写混淆文件

#---------------------------------webview------------------------------------
-keepclassmembers class fqcn.of.javascript.interface.for.Webview {
   public *;
}
-keepclassmembers class * extends android.webkit.WebViewClient {
    public void *(android.webkit.WebView, java.lang.String, android.graphics.Bitmap);
    public boolean *(android.webkit.WebView, java.lang.String);
}
-keepclassmembers class * extends android.webkit.WebViewClient {
    public void *(android.webkit.WebView, jav.lang.String);
}

编译时的注意事项：

可能会报错：

然后在proguard-rules.pro中添加去掉这部分混淆的代码：

#---------------------------------2.第三方包-------------------------------
-dontwarn com.google.**
-keep class com.google.**



#---------------------------------3.与js互相调用的类------------------------
