Question

我无法在Android Jelly Bean模拟器上与WhatsApp共享音频文件。我的代码当前可以在Lollipop和更高版本上运行，但我不知道为什么在较低设备上会发生此错误。

    val share = Intent(Intent.ACTION_SEND)

    share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)

    //Audio MIME type
    share.type = "audio/*"

    //File uri (from file provider on api level 24 or higher)
    share.putExtra(Intent.EXTRA_STREAM, fileUri(context))

    context.startActivity(Intent.createChooser(share, context.getString(R.string.share_title)))

内部fileUri方法

if (Build.VERSION.SDK_INT < 24)
        return Uri.fromFile(this)
    return FileProvider.getUriForFile(context, context.applicationContext.packageName
            + ".[myprovidername].provider", this)

Answer 1

那可能是因为WhatsApp需要Uri的列表，即使只有一个。尝试返回类似这样的内容

ArrayList<Uri> uriList = new ArrayList<Uri>();
uriList.add(Uri.fromFile(this));

代替

Uri.fromFile(this)

在Android 4.2上与WhatsApp共享音频文件失败
