FlutterJNI FlutterJNI 的作用就是架起 Android 端Java与 Flutter Engine C/C++ 端的一座接口桥梁。为了方便 JNI 接口的管理,这里将所有的 JNI 接口都封装在了 FlutterJNI 里,方便使用 大部分FlutterJNI中的调用都与特定的“platform view”相关,而“platform view”

java层启动过程 熟悉android的朋友都知道,一个APP启动会先执行Application再执行Activity(AndroidManifest.xml中配置的启动Activity),结合这个,我们先看看Application里做了什么,在分析过程中我们将挑取一些关键的native方法作为c++层入口方法作进一步的分析。 // io.flutter.app.FlutterApplicationpublicclassFlutterApplicationext...
Clicking the Resume button skips to the next exception (every network call basically). And if you have only "Uncaught exceptions" ticked, does it occur? If so, then I think this is likely the same issue asdart-lang/sdk#53334. A recent bug causes the VM to treat somecaughtexceptions as...
