Target host must not be null, or set in parameters

I get this error “Target host must not be null, or set in parameters”. My manifest file has internet permission set, and I have put ‘http://’ before my Url. It still gives the same error. My URL does not have a ‘www.’ attached to it.

Part of my Code:

  • Comparison of Speech Recognition use in Android: by Intent or on-thread?
  • Android 6.0 Marshmallow : Weird error with fragment animation
  • Select text from TextView?
  • Android: How to get a radiogroup with togglebuttons?
  • Android Layout Animations from bottom to top and top to bottom on ImageView click
  • Get all child views inside LinearLayout at once
  • HttpPost post = new HttpPost("http://infocreation.something_something1.xml");
    

    Part of my manifest is like below:

    <uses-permission android:name="android.permission.INTERNET/>
    

    What do I do now?

  • How to create the best Android app project structure with Android Studio and Gradle?
  • Android - Multiple .apk file from single code base
  • Should I use AppCompat v7 if minsdk is 14
  • Android icon vs logo
  • Android onClick method doesn't work on a custom view
  • How should I track Fragments in Google Analytics v4?
  • 3 Solutions collect form web for “Target host must not be null, or set in parameters”

    It should be

    HttpPost post = new HttpPost("http://www.infocreation.something.xml");
    

    So I replaced the URL, with almost the same URL, except without the underscore and that worked. I realized from further searches (for example here) that URLs with _(underscore) are not valid, although that particular URL may work. Thanks for all your help.

    Are you putting a real and working url inot the HttpPost constructor?

    Anyway this is your solution:

    If you have the following code failing:

    HttpGet httpget = new HttpGet("www.host.com");
    

    Then the error is pretty easy to solve:
    The problem is that you have not added a protocol to the URL, so change it to:

    HttpGet httpget = new HttpGet("http://www.host.com");
    

    And then it will work as wanted.
