我希望能够暂停/播放和跳过正在不同应用程序(例如 Spotify/Youtube Music 等)中播放的音乐。有没有办法在 Flutter 应用程序中控制它？

提前致谢!

最佳答案

据我所知，目前没有针对此的软件包。我有一个我正在尝试运行的仅限 Android 的应用程序，解决方案是创建一个平台 channel ，然后为此做一些事情。

package com.example.myapp

import android.content.Context
import android.content.Intent
import android.media.AudioManager
import android.os.Build
import android.os.Bundle
import android.os.Handler
import android.os.Looper
import android.view.KeyEvent
import androidx.annotation.RequiresApi
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugin.common.BinaryMessenger
import io.flutter.plugin.common.MethodChannel

class MainActivity: FlutterActivity() {
  private val METHOD_CHANNEL_NAME = "com.example.myapp/media_control"
  private var methodChannel: MethodChannel? = null
  private var audioManager: AudioManager? = null;

  @RequiresApi(Build.VERSION_CODES.O)
  override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
      super.configureFlutterEngine(flutterEngine)

      setupChannels(this, flutterEngine.dartExecutor.binaryMessenger)
  }

  @RequiresApi(Build.VERSION_CODES.O)
  override fun onCreate(savedInstanceState: Bundle?) {
      audioManager = context.getSystemService(Context.AUDIO_SERVICE) as AudioManager
      super.onCreate(savedInstanceState)
  }

  @RequiresApi(Build.VERSION_CODES.O)
  private fun setupChannels(mainActivity: MainActivity, binaryMessenger: BinaryMessenger) {
      methodChannel = MethodChannel(binaryMessenger, METHOD_CHANNEL_NAME)
      methodChannel!!.setMethodCallHandler { call, result ->
            if(call.method == "pause") {
                sendMediaButton(KeyEvent.KEYCODE_MEDIA_PAUSE)
                result.success("Success");
            }
            else if (call.method == "play") {
                sendMediaButton(KeyEvent.KEYCODE_MEDIA_PLAY)
                result.success("Success");
            }
            else if (call.method == "skipNext") {
                sendMediaButton(KeyEvent.KEYCODE_MEDIA_NEXT)
                result.success("Success");
            }
            else if (call.method == "skipPrevious") {
                sendMediaButton(KeyEvent.KEYCODE_MEDIA_PREVIOUS)
                result.success("Success");
            }
      }
  }

    private fun sendMediaButton(keyCode: Int) {
        var keyEvent = KeyEvent(KeyEvent.ACTION_DOWN, keyCode)
        audioManager!!.dispatchMediaKeyEvent(keyEvent)

        keyEvent = KeyEvent(KeyEvent.ACTION_UP, keyCode)
        audioManager!!.dispatchMediaKeyEvent(keyEvent)
    }

}
