大家好，我正在制作一个 android 应用程序来通过我的应用程序接听所有来电所以我自己问
下面的代码不适用于棉花糖及以上。这段代码一直有效到 Lolipop。
private void acceptCall_n() {
// for HTC devices we need to broadcast a connected headset
boolean broadcastConnected = MANUFACTURER_HTC.equalsIgnoreCase(Build.MANUFACTURER)
&& !audioManager.isWiredHeadsetOn();
if (broadcastConnected) {
broadcastHeadsetConnected(false);
}
try {
try {
// logger.debug("execute input keycode headset hook");
Runtime.getRuntime().exec("input keyevent " +
Integer.toString(KeyEvent.KEYCODE_HEADSETHOOK));
} catch (IOException e) {
Log.e("Call Exception ",e.toString());
HelperMethods.showToastS(getBaseContext(),"Call Exception one "+e.toString());
// Runtime.exec(String) had an I/O problem, try to fall back
// logger.debug("send keycode headset hook intents");
String enforcedPerm = "android.permission.CALL_PRIVILEGED";
Intent btnDown = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN,
KeyEvent.KEYCODE_HEADSETHOOK));
Intent btnUp = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,
KeyEvent.KEYCODE_HEADSETHOOK));
sendOrderedBroadcast(btnDown, enforcedPerm);
sendOrderedBroadcast(btnUp, enforcedPerm);
}
}catch (Exception e){
e.printStackTrace();
Log.e("Call Exception two",e.toString());
HelperMethods.showToastS(getBaseContext(),"Call Exception two "+e.toString());
}finally {
if (broadcastConnected) {
broadcastHeadsetConnected(false);
}
}
}
