放在哪里code为全球硬件密钥监听器？ [英] Where to put code for a global hardware key listener?

问题描述

我试图破解硬件的关键支撑到现有的应用程序，但感悟到我知道的太少Android应用开发的继续。结果
我可以反编译，并重新编译应用程序，而无需使用APKtool问题，我做了一个小的应用程序自己用的​​硬件关键支撑拉动编译smali code出来。作为参考，这部分是这样的：

 。方法公开的onkeydown（ILandroid /查看/ KeyEvent的;）z
 

如果我想有应用程序监听硬件钥匙全球（即在每一次活动，窗口，什么具备的，你的应用程序的），在那里应该我把的onkeydown code吗？难道我把它在一个单一的活动（如果是这样，哪一个），在所有的活动，或别的地方干脆？

编辑：我实现了全球这里是一个有点暧昧。我的意思是在整个应用程序，而不是系统范围。

解决方案

  

如果我想有应用程序监听硬件钥匙全球（即在每一次活动，窗口，什么具备的，你的应用程序），我在哪里应该放的onkeydown code？

您下载的Andr​​oid源$ C ​​$ C，修改它有某种全球硬件密钥的处理程序，编译修改的源，将其打包为ROMmod，并在设备上安装的ROMmod。

否则，只有前景活性（或，有时，窗口）将接收的按键事件。

I'm trying to hack hardware key support into an existing app, but came to realize I know too little of Android app development to continue.
I can decompile and recompile the app without problems using APKtool, and I made a small app myself with hardware key support to pull the compiled smali code out of. For reference, that part looks like this:

.method public onKeyDown(ILandroid/view/KeyEvent;)Z

If I want to have the app listen for hardware keys "globally" (i.e. in every activity, window, what-have-you, of the app), where ought I put the onKeyDown code? Do I put it in a single activity (if so, which one), in all activities, or someplace else altogether?

Edit: I realize "globally" is a bit ambiguous here. I mean throughout the entire app, not system-wide.

解决方案

If I want to have the app listen for hardware keys "globally" (i.e. in every activity, window, what-have-you, of the app), where ought I put the onKeyDown code?

You download the Android source code, modify it to have some sort of global hardware key handler, compile the modified source, package it into a ROM mod, and install the ROM mod on your device.

Otherwise, only the foreground activity (or, sometimes, window) will receive key events.
