这样才能保证中兴T815 Android手机交付行动HEADSET_PLUG的 [英] Way to ensure delivery of Action HEADSET_PLUG for ZTE T815 Android phone

问题描述

我已经注册一个BroadcastReceiver接收ACTION_HEADSET_PLUG这对于大多数设备工作正常，即每当耳机插入或拔下它被调用。但在其他如中兴T815，其意图是从来没有当耳机插入发送/接收/拔出。

有关参考这里是code接收机注册：

 私人最终的BroadcastReceiver headsetPlugReceiver =新的广播接收器（）{    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        Log.d（TAG，收到的意图=+意向）;
        如果（intent.getAction（）。equalsIgnoreCase（Intent.ACTION_HEADSET_PLUG））{
            //做的东西
        }
    }
};公共无效的onCreate（捆绑savedState）{
    super.onCeate（savedState）;
    // ...
    registerReceiver（headsetPlugReceiver，新的IntentFilter（Intent.ACTION_HEADSET_PLUG））;
}
 

更多信息：
其目的是派出，但HEADSET_HOOK命令在耳机解雇之后。

而当意图是派出

 最终诠释麦克风= intent.getIntExtra（话筒，0）;
 

总是返回0（即没有麦克风）。

所以

1. 有一些配置/ code，它可以迫使这个交付
   意图？


2. 如何获得的意图，正确地报告是否
   麦克风的存在与否？

解决方案

原来，中兴T815具有OMTP TRRS配置其音频插孔，而不是CTIA / AHJ像其他现代的Andr​​oid设备。

请参阅 http://en.wikipedia.org/wiki/Phone_connector_%28audio%29

事务中的悲惨状态，尝试使用音频供给inpout跨产品时尤其如此。

I have registered a BroadcastReceiver to receive ACTION_HEADSET_PLUG which works fine for most devices, ie it is called whenever the headset is plugged or unplugged. But on others eg the ZTE T815, the Intent is never sent/received when the headset is plugged/unplugged.

For reference here is the code for the receiver registration:

private final BroadcastReceiver headsetPlugReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG, "Received intent=" + intent);
        if (intent.getAction().equalsIgnoreCase(Intent.ACTION_HEADSET_PLUG)) {
            // do stuff
        }
    }
};

public void onCreate(Bundle savedState) {
    super.onCeate(savedState);
    // ...
    registerReceiver(headsetPlugReceiver, new IntentFilter(Intent.ACTION_HEADSET_PLUG));
}

Further info: The Intent is dispatched but only after the HEADSET_HOOK command is fired on the headset.

And when the Intent is dispatched

final int microphone = intent.getIntExtra("microphone", 0);

always returns 0 (ie no microphone).

So

1. Is there some config/code that can force the delivery of this Intent?
2. How do I get the Intent to correctly report whether a microphone exists or not?

解决方案

It turns out the ZTE T815 has an OMTP TRRS config for its audio socket instead of CTIA/AHJ like every other modern Android device.

See http://en.wikipedia.org/wiki/Phone_connector_%28audio%29

A sad state of affairs, especially when trying to use audio feed inpout across products.
