Xposed

Xposed能够勾住(Hook) Android应用程序对象的方法，实现AOP，一个简单的例子：

public class WebViewHook implements IXposedHookLoadPackage {    // handleLoadPackage 会在android加载每一个apk后执行    public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {           // 可以从lpparam中获取当前apk的名字        if (! lpparam.packageName.equals("com.tencent.mobileqq")) {            return;        }        XposedBridge.log("WebViewHook handleLoadPackage: " + lpparam.packageName);        // 勾住 WebView 所有的构造器        XposedBridge.hookAllConstructors(WebView.class, new XC_MethodHook() {            @Override            protected void beforeHookedMethod(MethodHookParam param) throws Throwable {                // 打开webContentsDebuggingEnabled                XposedHelpers.callStaticMethod(WebView.class, "setWebContentsDebuggingEnabled", true);                XposedBridge.log("WebViewHook new WebView(): " + packageName);            }        });    }}

上面的代码可以为QQ打开WebView的webContentsDebuggingEnabled
