ringtonemanager-getting the system's current ringtone

We look directly at the code

The code above is the code to get three ringtones for your phone.

In fact, the operation of getting ringtones is also very simple.

It mainly involves two classes of

1.ringtonemanager-Ringtone Management class

2.ringtone-Ringtones Operation class

It's basically a three-step process.

1. Get the URI

To get the URI method, you need to pass in a parameter ringtonemanager.type_notification (stream_notification). ) is

This parameter determines what kind of tone we get.

2. Get ringtone

The way to get it requires the first step to get the URI to come in, you can get the corresponding ringtone

3. Operation Ringtones

Only play () stop () is used to control the stop and play of the ringtone directly.

There is a method above

Mringtone_alarm.setstreamtype (Audiomanager.stream_alarm);

Say is set audio stream, this audio stream is what thing, also do not understand, saw someone said

in the audio subsystem of the Android Framework, each audio stream corresponds to an instance of a Audiotrack class, and each audiotrack is registered to Audioflinger when it is created. All audiotrack are mixed (Mixer) by Audioflinger and then transported to the audiohardware for playback. Audiotrack and Audioflinger communication mechanisms Typically, audiotrack and Audioflinger are not in the same process, and they connect through the binder mechanism in Android.

I checked the information, the feeling should be to control what audio parsing it
