在小部件中录制音频出现错误 Android Studio

如何解决在小部件中录制音频出现错误 Android Studio

我想制作可以通过按小部件 3 次来录制音频的应用程序，但是当我尝试录制时出现如下错误

我使用 Kotlin 编写代码，这是我的代码

在小部件中：

class PanicButton : AppWidgetProvider() {
    companion object {
        private const val KEY_ACTION = "action_record"
        private const val KEY_ID = "id_record"

        @Volatile
        private var count = 0
    }

    override fun onUpdate(
        context: Context,appWidgetManager: AppWidgetManager,appWidgetIds: IntArray
    ) {
        // There may be multiple widgets active,so update all of them
        for (appWidgetId in appWidgetIds) {
            updateAppWidget(context,appWidgetManager,appWidgetId)
        }
    }

    override fun onReceive(context: Context,intent: Intent) {
        super.onReceive(context,intent)
        if (intent.action == KEY_ACTION) {
            count++
            Handler(Looper.getMainLooper()).postDelayed({
                count = 0
            },3000)
            when (count) {
                3 -> {
                    Toast.makeText(context,"Berhasil",Toast.LENGTH_SHORT).show()
                    RecordActivity.recording("${context.externalCacheDir?.absolutePath!!}/record.mpeg")
                    
                    val manager = AppWidgetManager.getInstance(context)
                    val views = RemoteViews(context.packageName,R.layout.panic_button)
                    views.setImageViewResource(R.id.recordButton,R.drawable.recording)
                    val id = intent.getIntExtra(KEY_ID,-1)
                    manager.updateAppWidget(id,views)

                    Handler(Looper.getMainLooper()).postDelayed({
                        views.setImageViewResource(R.id.recordButton,R.drawable.record)
                        manager.updateAppWidget(id,views)
                    },3000)
                }
                2 -> Toast.makeText(context,"Tekan sekali lagi",Toast.LENGTH_SHORT).show()
                1 -> Toast.makeText(context,"Tekan dua kali lagi",Toast.LENGTH_SHORT).show()
            }
        }
    }

    private fun updateAppWidget(
        context: Context,appWidgetId: Int
    ) {
        val views = RemoteViews(context.packageName,R.layout.panic_button)
        views.setOnClickPendingIntent(R.id.recordButton,getPending(context,appWidgetId))

        appWidgetManager.updateAppWidget(appWidgetId,views)
    }

    private fun getPending(context: Context,id: Int): PendingIntent {
        val intent = Intent(context,PanicButton::class.java)
        intent.action = KEY_ACTION
        intent.putExtra(KEY_ID,id)
        return PendingIntent.getBroadcast(context,id,intent,0)
    }
}

在记录活动伴侣对象中：

fun recording(data: String) {
    val recorder = MediaRecorder().apply {
        setAudioSource(MediaRecorder.AudioSource.MIC)
        setOutputFormat(MediaRecorder.OutputFormat.MPEG_4)
        setOutputFile(data)
        setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB)

        try {
            prepare()
        } catch (e: Exception) {
            e.printStackTrace()
        }
        start()
        println("START RECORDING")
    }
    Handler(Looper.getMainLooper()).postDelayed({
        recorder.apply {
            stop()
            release()
        }
        println("FINISH RECORDING")
    },3000)
}

我已经尝试了很多方法来输入它，但会不会是因为我尝试使用 Companion Object 中的函数进行录制？

非常感谢您回答我的问题...
