拦截系统函数出错
android o上尝试拦截 android.webkit.WebView的loadUrl方法
代码如下： Class<?> webViewClass = getClassLoader().loadClass("android.webkit.WebView"); HookManager.findAndHookMethod(webViewClass, "loadUrl", String.class, new MethodCallback() { @Override protected void beforeHookedMethod(MethodHookParam param) throws Throwable { super.beforeHookedMethod(param); Log.d("panda", "i'm in method " +param.method.getName()+" beforeHookedMethod"); } @Override protected void afterHookedMethod(MethodHookParam param) throws Throwable { super.afterHookedMethod(param); Log.d("panda", "i'm in method " +param.method.getName()+" afterHookedMethod"); } }); 异常如下： E/AndroidRuntime: FATAL EXCEPTION: main Process: com.panda.hook.andhook, PID: 17591 java.lang.VerifyError: Verifier rejected class com.panda.hook.andhook.MainActivity: void com.panda.hook.andhook.MainActivity.onCreate(android.os.Bundle) failed to verify: void com.panda.hook.andhook.MainActivity.onCreate(android.os.Bundle): [0x4B] 'this' argument 'Reference: com.panda.hook.andhook.MyWebview' not instance of 'Reference: android_webkit_WebView' (declaration of 'com.panda.hook.andhook.MainActivity' appears in /data/app/com.panda.hook.andhook-jnxRzI9vY8XQW7tN8LeIQA==/split_lib_slice_0_apk.apk) at java.lang.Class.newInstance(Native Method) at android.app.Instrumentation.newActivity(Instrumentation.java:1174) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2669) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2856) at android.app.ActivityThread.-wrap11(Unknown Source:0) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1589) at android.os.Handler.dispatchMessage(Handler.java:106) at android.os.Looper.loop(Looper.java:164) at android.app.ActivityThread.main(ActivityThread.java:6494) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:438) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:807)
