Android Download Manager "download Unsuccessful"

This is my first time trying to implement DownloadManager and no matter what I try, I always get a notification saying 'Download unsuccessful.' I've looked at many other SO forums,

Solution 1:

This issue occur due to network security. If You are using un-secure url in above pie API, then it can't execute your url. Check Official Documentation.

Reason for avoiding cleartext traffic is the lack of confidentiality, authenticity, and protections against tampering; a network attacker can eavesdrop on transmitted data and also modify it without being detected.

Add following in manifest to bypass all security.

<applicationandroid:name=".ApplicationClass"....android:usesCleartextTraffic="true">

I spent a day on using Download Service and finally it worked. To sum it up for anyone who wants to try for the first time:

1. Dont't forget to add WRITE_EXTERNAL_STORAGE and INTERNET permissions in Manifest.
2. use requestPermissions() to grant permission from user.
3. use getExternalFilesDir() instead of getExternalStorageDirectory().
4. If you're downloading from http:// so add usesCleartextTraffic="true" to manifest.
