使用Mediastore API保存音频文件会在API 28-上引发RemoteException

如何解决使用Mediastore API保存音频文件会在API 28-上引发RemoteException

我没有找到任何官方文档来说明如何使用MediaStore API将音频文件保存在外部存储中。 在API 29+上，一切正常。在API 28上，我收到此错误：

E/JavaBinder: *** Uncaught remote exception!  (Exceptions are not yet supported across processes.)
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
    at java.lang.String.substring(String.java:2036)
    at com.android.providers.media.MediaProvider.insertFile(MediaProvider.java:2188)
    at com.android.providers.media.MediaProvider.insertInternal(MediaProvider.java:2592)
    at com.android.providers.media.MediaProvider.insert(MediaProvider.java:1872)

    at android.content.ContentProviderNative.onTransact(ContentProviderNative.java:152)
    at android.os.Binder.execTransact(Binder.java:731)

这是我使用的代码（当我叫“插入”时，我得到一个空的Uri）：

 //@RequiresApi(VERSION_CODES.Q)
@SuppressLint("InlinedApi")
private fun export(name: String,path: String) {
    val resolver = applicationContext.contentResolver
    val audioCollection =  if (VERSION.SDK_INT >= VERSION_CODES.Q) {
        MediaStore.Audio.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
    } else {
        MediaStore.Audio.Media.getContentUri(MediaStore.VOLUME_EXTERNAL)
    }

    val newAudioFileDetails = ContentValues().apply {
        put(MediaStore.Audio.Media.DISPLAY_NAME,name)
        put(MediaStore.Audio.Media.DATA,"data")
        put(MediaStore.Audio.Media.IS_PENDING,1)
    }

    val recordingUri = resolver.insert(audioCollection,newAudioFileDetails)
    Log.d(TAG,"recording Uri: ${recordingUri.toString()}")
    recordingUri?.let { recordingUri ->
        resolver.openFileDescriptor(recordingUri,"w")?.use {
            val bytesCopied = File(path).inputStream().copyTo(FileOutputStream(it.fileDescriptor))
            Log.d("TAG","bytes copied: $bytesCopied")
        }

        newAudioFileDetails.let {
            it.clear()
            it.put(MediaStore.Audio.Media.IS_PENDING,0)
            resolver.update(recordingUri,it,null,null)
        }
    }
}

编辑 我也尝试过这样做，但是插入时我总是得到一个空的Uri：

val newAudioFileDetails = ContentValues().apply {
        put(MediaStore.Audio.Media.DISPLAY_NAME,name)
        put(MediaStore.Audio.Media.IS_PENDING,1)

        if (VERSION.SDK_INT < VERSION_CODES.Q) {
            val audioDir = File(Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_MUSIC),"MyNewAlbumName")
            val audioPath = File(audioDir,"$name.mp3").absolutePath
            put(MediaStore.Audio.AudioColumns.DATA,audioPath)
        }
