Xposed work well, bug log shows error

[zjns]

device: xiaomi mi3w system: lineage 14.1 xposed version: v88 offical wiped dalvik-cache after flash xposed framwork: yes xposed module: twitter adfree, weiboxposed app: Twiiter, weibo the problem I found it exist on some xposed modules. like twitter adfree, weiboxposed, the modules work well on cm13 with v87 xposed framework and haven't any error. but on lineage14.1, there has some error but should not being here.

in fact, the class “com.sina.weibo.models.MBlogListBaseObject” is existed, but log shows it can't be find. the module works well bug log shows error. so I think this is a problem about xposed framework.

[rovo89]

Please contact the module developer. These errors are most likely from incompatible modules, e.g. because the apps they're hooking has changed. The class lookup mechanism is standard Java stuff, not Xposed-specific.

If you are the module developer, please link to the relevant code of the module which is doing the hook. And show the smali of the exact version of the app that you're trying to hook.

[zjns]

OK, I'll contact the author of "WeiboXposed" to solve the problem together. BTW, why "ClassNotFoundException" of the two apps all aim to the "com.google.android.webview", not the apps themselves.

[rovo89]

Good catch. It's possible that the wrong class loader is used here. And yes, then there's a chance that this is actually caused by the framework giving you the wrong classloader.

[pikrzysztof]

@rovo89 full logs disable XPosed (it fails to run) and everything fails to work, so while this particular bug (I mean WeiboXposed errors) is not XPosed problem, it showed another one.

[zjns]

I think the problem probably caused by time point when hook a method. eg. when open an app, maybe some classes will not load immediately, but Xposed module's hook function is going, so log shows not find class, just because of hook time point is too early. So this problem is caused by Xposed module, not caused by Xposed. And I think this maybe have some connection with Nougat art, not same with Marshmallow art; so Marshmallow Xposed didn't shows error, but Nougat Xposed shows error when use some Xposed modules.

[zjns]

@rovo89 I fond what thing cause the errors finally, the solve way is to close option "Multiprocess Webview" in "developer options". I am so excited to find it.

[zjns]

@rovo89 the issue could be closed.

[aviraxp]

Sorry, but any updates on this issue? This makes my module almost 100% broken.

[wanam]

I am the author of Twitter Adfree module, unfortunately i did not manage to reproduce that error. Disabling a feature under developer options is not a solution, As rovo89 said maybe the used classloader is wrong, no idea how it may get the wrong one, the class loader is assigned here.

And it is the same one i'm using:

    @Override
    public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
        if (lpparam.packageName.equals(COM_TWITTER)) {

            Class<?> mTweetView = null;
            try {
                mTweetView = XposedHelpers.findClass("com.twitter.tweetview.TweetView", lpparam.classLoader);
                XposedHelpers.findAndHookMethod(mTweetView, "e", boolean.class, new XC_MethodHook() {

                    @Override
                    protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                        // promoted_badge visibility
                        boolean visibility = (Boolean) param.args[0];

                        // if badge is going to be visible, just hide
                        // the tweet
                        if (visibility) {
                            ViewGroup vg = (ViewGroup) param.thisObject;
                            vg.setVisibility(View.GONE);
                            param.setResult(null);
                            return;
                        }
                    }
                });
            } catch (Throwable e) {
                XposedBridge.log(e);
            }
        }
    }
