How to check what is the latest version of a dependency to use in gradle

Question

I've always added dependencies like this:

dependencies {     compile 'com.android.support:mediarouter-v7:19.+' } 

but in the recent versions of Android Studio, they recommend not to use the + as it can lead to errors. How to know what's the latest version? I can try every combination of 19.y.x until gradle complains, but what's the real way do check?

edit: sometimes, that page helps me figure it out.

There may be other ways, but here is what i use:

You can find out the latest version using Android Studio by replacing the version number of your library in build.gradle compile line, with just + , and click on Sync Now in upper right corner of the window.

in your case, for example

dependencies { compile 'com.android.support:mediarouter-v7:+' }

Android Studio will pop up a hint/bulb, which has options Replace with specific version you can click, which will fill-in the latest version in-place of +. Please see below screeshot:

If this doesn't work the first time, let gradle complete its sync, and retry (replace + with + or any file modification will do, click the sync now again and hint bulb will show up).

For example, for your library, i simply pasted this line compile 'com.android.support:mediarouter-v7:+' under my dependencies and followed the above process, Android Studio filled in with below version
