How to run many HTTP connections in android?

Question

I have a list with id's which i'm going to use in URL's, to get some data using HttpConnection. I was trying to use AsyncTask from the loop, but it was a bad idea, because my program crashed with:

java.lang.OutOfMemoryError: Failed to allocate a 124606360 byte allocation with 16777216 free bytes and 103MB until OOM

How to make many connections one after another correctly?

This has nothing to do with "many connections". You are attempting to allocate a ~120MB block of heap space, and that will fail nearly all of the time. — CommonsWare, May 04 '17 at 12:31
`to get some data` What kind of data? And where do you want to put it? — greenapps, May 04 '17 at 12:40

You can try to add android:largeHeap="true" your in your AndroidManifest.xml

<application
    android:allowBackup="true"
    android:hardwareAccelerated="false"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

Or you can try using network library such us Volley, Okhttp, Retrofit, etc.
