通过以上步骤,就可以在Android Studio中使用JNI了。首先配置NDK,然后创建JNI文件并实现本地方法,编译生成动态库,最后在Java代码中调用本地方法。这样就可以在Java代码中调用C/C++代码,实现更高效的功能和更好的性能。 参考资料: [Android Developer Documentation - JNI]( [Android Developer Documentation - NDK](...

可选项: Documentation for AndroidSdk:安卓开发者官网的一些离线文档 Samples for SDK:此项在高版本tools中已不提供,需要在IDE里通过Import Sample引入,当然也可以下载离线版),内置的安卓示例程序,推荐安装。 Sources for Android SDK:安卓API的源代码,推荐安装。
The Android Studio editor has a considerable amount of built-in knowledge of Java programming syntax and the classes and methods that make up the Android SDK, as well as knowledge of your own code base. As code is typed, the editor scans what is being typed and, where appropriate, makes ...
QUT 也能同时获取到 Java 堆栈(因为可以回溯 JNI/OAT/JIT)。在需要回溯出 Java 堆栈的情况下,我们也尝试对比了 QUT 和 native 获取 Java 堆栈的性能,总的来说 QUT 有基本不输于 Java 堆栈的获取性能(遇到性能较差的机器可能会稍好一些),而且避免了涉及和改变虚拟机状态,适用性会更广一点。
