 <p>I add this as a response as I can't add long comments. I have checked the .pom files of the maven repository. The main difference between 2.3.2 and 2.4.0/2.5.0 is that 2.4.0/2.5.0 add some exclusions to the dependency:</p> <pre><code>&lt;exclusions&gt; &lt;exclusion&gt; &lt;artifactId&gt;crashlytics-core&lt;/artifactId&gt; &lt;groupId&gt;com.crashlytics.sdk.android&lt;/groupId&gt; &lt;/exclusion&gt; &lt;exclusion&gt; &lt;artifactId&gt;crashlytics-ndk&lt;/artifactId&gt; &lt;groupId&gt;com.crashlytics.sdk.android&lt;/groupId&gt; &lt;/exclusion&gt; &lt;exclusion&gt; &lt;artifactId&gt;digits&lt;/artifactId&gt; &lt;groupId&gt;com.digits.sdk.android&lt;/groupId&gt; &lt;/exclusion&gt; &lt;exclusion&gt; &lt;artifactId&gt;crashlytics&lt;/artifactId&gt; &lt;groupId&gt;com.crashlytics.sdk.android&lt;/groupId&gt; &lt;/exclusion&gt; &lt;exclusion&gt; &lt;artifactId&gt;beta&lt;/artifactId&gt; &lt;groupId&gt;com.crashlytics.sdk.android&lt;/groupId&gt; &lt;/exclusion&gt; &lt;/exclusions&gt; </code></pre>
