uni-app 仅仅音频聊天原生插件 Android IOS双端

针对uni-app中实现音频聊天功能的需求，你可以通过开发原生插件来分别在Android和iOS平台上实现该功能。以下是一个简化的代码示例，展示了如何在Android和iOS上分别创建音频聊天的原生插件。

Android端原生插件

首先，在Android平台上，你可以使用AudioRecord和AudioTrack类来实现音频录制和播放。以下是一个简化的插件实现：

MyAudioPlugin.java

package com.example.uniappplugin;

import android.media.AudioFormat;
import android.media.AudioManager;
import android.media.AudioRecord;
import android.media.AudioTrack;
import android.util.Log;
import io.dcloud.feature.uniapp.bridge.UniJSCallback;
import io.dcloud.feature.uniapp.common.UniModule;

public class MyAudioPlugin extends UniModule {

    private AudioRecord audioRecord;
    private AudioTrack audioTrack;

    public void startAudioChat(UniJSCallback callback) {
        int sampleRateInHz = 44100;
        int audioBufferSize = AudioRecord.getMinBufferSize(sampleRateInHz,
                AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT);

        audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC,
                sampleRateInHz, AudioFormat.CHANNEL_IN_MONO,
                AudioFormat.ENCODING_PCM_16BIT, audioBufferSize);

        audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC,
                sampleRateInHz, AudioFormat.CHANNEL_OUT_MONO,
                AudioFormat.ENCODING_PCM_16BIT, audioBufferSize,
                AudioTrack.MODE_STREAM);

        audioRecord.startRecording();
        audioTrack.play();

        // Start a thread to read from audioRecord and write to audioTrack
        new Thread(() -> {
            byte[] buffer = new byte[audioBufferSize];
            while (true) {
                int read = audioRecord.read(buffer, 0, buffer.length);
                audioTrack.write(buffer, 0, read);
            }
        }).start();

        callback.invoke("Audio chat started");
    }

    public void stopAudioChat(UniJSCallback callback) {
        if (audioRecord != null) audioRecord.stop();
        if (audioTrack != null) audioTrack.stop();
        callback.invoke("Audio chat stopped");
    }
}

iOS端原生插件

在iOS平台上，你可以使用AVAudioSession和AVAudioRecorder/AVAudioPlayer来实现音频录制和播放。以下是一个简化的插件实现：

MyAudioPlugin.m

#import <Foundation/Foundation.h>
#import <AVFoundation/AVFoundation.h>
#import <UniAppPlugin/UniAppPlugin.h>

@interface MyAudioPlugin : NSObject <UniModule>

@end

@implementation MyAudioPlugin

- (void)startAudioChat:(NSDictionary *)args resolver:(UniJSResolver)resolver rejecter:(UniJSRejecter)rejecter {
    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];
    [audioSession setActive:YES error:nil];

    NSURL *url = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:@"audio.caf"]];
    AVAudioRecorder *recorder = [[AVAudioRecorder alloc] initWithURL:url settings:nil error:nil];
    [recorder record];

    // Play the recorded audio in real-time (not recommended for production, just for simplicity)
    AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
    [player play];

    resolver(@"Audio chat started");
}

- (void)stopAudioChat:(NSDictionary *)args resolver:(UniJSResolver)resolver rejecter:(UniJSRejecter)rejecter {
    // Assuming you have a reference to the recorder and player instances
    [recorder stop];
    // You should find a way to stop the player without delay
    resolver(@"Audio chat stopped");
}

@end

请注意，这些代码只是演示性的，并未处理所有可能的错误和边界情况。在实际应用中，你需要添加更多的错误处理和资源管理逻辑。
