Question

我想在Android中创建宏应用程序，这将帮助用户设置为用户执行计划任务的要求，如预定的视频录制（如Windows操作系统中的camstudio），GPS，蓝牙，摄像头控制。我知道必须根据设备做这些事情。

Advance Features :    
• Shake the device to upload the last photo to Facebook.    
• Turn on Wi-fi or Data connection when you launch a particular app (and off again when closed).
• Respond to an incoming SMS by sending your current location.    
• Toggle the power button to tell you the time (e.g. when its in your pocket).    
• Use NFC tags to configure the device (turn on bluetooth, set volume etc).

实际上，除了预定视频录制之外，我还有代码可以执行所有操作。

你们可以帮助我 ..

干杯：）

Answer 1

您实际上不必使设备具有这些功能。你需要的是Service，它实现了各种监听器，例如：

SensorListener到detect shaking of device。
BroadcastReceiver to fire when SMSs are received.
或Handle WiFi.

您可以使用SpotRecorder（house4hack）代码尝试使用，该代码包含在后台启动RecorderService服务的活动（我们需要进行查看以使其不可见。这应该在服务中完成）< / p>

我们可以使用AlarmManager来设置特定时间的警报，当警报管理器通过使用意图再次启动您的服务来触发该时间时，可以使用相同的方法来停止您的应用程序。

不确定，但您可以尝试使用WindowManager并从服务中调用它。看看这次失败的尝试here。
