Android-support-v4 库在 B4A 中没有 JobIntentService

Question

I have a library and it depends on Android-support-v4 (The JobIntentService class). I'm going to use it in Basic4Android.

There are two ways of adding supprt-v4 dependency to project:

• Add
  <dependsOn>com.android.support:support-v4</dependsOn>
  to library xml.
• Add

dependsOn>support-annotations</dependsOn>
<dependsOn>support-compat</dependsOn>
<dependsOn>support-v4</dependsOn>
<dependsOn>support-core-ui</dependsOn>
<dependsOn>support-core-utils</dependsOn>
<dependsOn>support-fragment</dependsOn>
<dependsOn>support-media-compat</dependsOn>

to that xml.

If I use the first way, I can't find JobIntentService . If I use the second way it's fine, but It will have a conflict with the AppCompat library.

So how an I have a complete code of support-v4 without experiencing conflicts?

I know that JobIntentService exists in support-compat part of android-support-v4, but adding it beside com.android.support:support-v4 still causes duplications.

Since the first way uses Maven artifacts to get your library from Jcenter , it might download an old version that does not include this class in it's class path.

To resolve this clear libraries of B4A placed in the sdk m2repository folder named b4a_remote , delete it and let the B4A redownload the files. Therefore it will download fresh and updated libraries that contain this class.
