首先,在這個問題上有很多問題,但沒有一個反映我的問題。例如,我讀了this和this。DownloadManager IllegalStateException在DIRECTORY_DOWNLOADS中創建下載文件
,我有這個問題,是在非常少數情況下,我的功能setDestinationInExternalPublicDir
結果在下面的堆棧跟蹤:

我使用的是標準Environment
不斷告訴DownloadManager
保存文件的位置。
android.app.DownloadManager dm = (android.app.DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse("url.to.file.ext"));
request.setMimeType("mime/type");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
Utils.setDownloadRequestVisibility(request, android.app.DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "file.ext");
request.setTitle(context.getString(R.string.download));
dm.enqueue(request);
如前所述,甚至有1%的用戶可能會遇到此錯誤。什麼可能導致它?
