SecurityException:权限被拒绝ACCESS_ALL_DOWNLOADS [英] SecurityException: Permission Denial ACCESS_ALL_DOWNLOADS

问题描述

我正在尝试使用DownloadManager下载文件.是的，我知道人们已经收到此错误.但是我的似乎还没有解决.我每次都尝试过.

I am trying to download files using DownloadManager. Yes I know people already got this error. but mine does not seems to be resolved. I have tried everytime.

我已取消此权限:

<使用权限android:name ="android.permission.INTERNET"/>< uses-permission android:name ="android.permission.ACCESS_ALL_DOWNLOADS"/>< uses-permission android:name ="android.permission.WRITE_EXTERNAL_STORAGE"/>

我的代码

public void startDownload(String str) {
    try {
        MarshmellowPermissions permissions = new MarshmellowPermissions(context);
        permissions.checkWriteExternalStoragePermission();
        DownloadManager mManager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
        DownloadManager.Request mRqRequest = new DownloadManager.Request(Uri.parse(str));
        mRqRequest.setDescription("This is Test File");
        long idDownLoad = mManager.enqueue(mRqRequest);
        mManager.remove(idDownLoad);
        try {
            mManager.openDownloadedFile(idDownLoad);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

}

此行出现错误

mManager.openDownloadedFile(idDownLoad);

这是错误日志:

java.lang.SecurityException:权限被拒绝:从pid = 3926读取com.android.providers.downloads.DownloadProvider uri content://downloads/all_downloads/15，uid = 10086需要android.permission.ACCESS_ALL_DOWNLOADS，或grantUriPermission()

推荐答案

看起来还没有人对此有一个答案，我已经解决了这个问题，并希望分享我的解决方法.因此，基本上，这是行不通的，因为我没有在运行时请求权限.

Look's like no one has an answer for this yet, I have already solved the issue and wanted to share how I solved it. So basically It wasn't working because I wasn't asking for permission on runtime.

我所做的是向运行时询问权限.在下面使用此代码.

What I did was ask the permission on runtime. Using this code below.

ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
