a. 在我通过下载下载的Im中:
val downloadId: Long = downloadManager.enqueue(dr)
If user reopenning application, i m checking downloading status via:
fun isDownloadInProgress(): Boolean {
val dq: DownloadManager.Query = DownloadManager.Query()
dq.setFilterById(downloadId)
val cursor: Cursor? = downloadManager.query(dq)
if (cursor == null || !cursor.moveToFirst()) {
return false
}
val status: Int = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS))
if (status == DownloadManager.STATUS_RUNNING || status == DownloadManager.STATUS_PENDING) {
return true
}
return false
}
有了这部法典,我在小小小米的rash泥中发生了几起坠毁事件,有11和12种。

我的问题是:
- If am i using
DownloadManagerincorrect and there is another way for check download status, can someone suggest how to do this? - If is this a bug on Xiaomi ROM, can someone give me the link on issue?
感谢。
