Ok I had to change the start of my build.gradle file to this ....

<pre><code>android {
 buildToolsVersion project.androidToolsVersion
 compileSdkVersion project.androidSDKVersion.toInteger()
 sourceSets {
 main {
 manifest.srcFile 'AndroidManifest.xml'
 java.srcDirs = ['src']
 resources.srcDirs = ['src']
 aidl.srcDirs = ['src']
 renderscript.srcDirs = ['src']
 res.srcDirs = ['res']
 assets.srcDirs = ['assets']
 jniLibs.srcDir 'libs'
 }

 instrumentTest.setRoot('tests')
 }
}

// needed to add JNI shared libraries to APK when compiling on CLI
tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask -&gt;
 pkgTask.jniFolders = new HashSet&lt;File&gt;()

}
RBC*/
</code></pre>

I added the line:

<pre><code>jniLibs.srcDir 'libs'
</code></pre>

and I commented out 

<pre><code>// needed to add JNI shared libraries to APK when compiling on CLI
tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask -&gt;
 pkgTask.jniFolders = new HashSet&lt;File&gt;()
 pkgTask.jniFolders.add(new File(projectDir, 'libs'))
}
</code></pre>

In the <code>C:\Users\plankton\Desktop\ThePlaneThatCouldntFly\flappytrip\android\build.gradle</code> file.

I came about this solution after reading this <a href="https://github.com/libgdx/libgdx/issues/3027">https://github.com/libgdx/libgdx/issues/3027</a>

blocks|key|117112|text|在尝试将"Libgdx跨平台游戏开发Cookbook“中的libgdx-cookbook示例导入Android+Studio2.1.1时，我也遇到了同样的问题。在我的例子中，它是通过简单的：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|117113|117114|导入/samples项目；|unordered-list-item|style|CODE|117115|不升级android子项目下的Gradle+plugin+when+prompted;|117116|updating+build.gradle文件，使其使用我拥有的buildToolsVersion和compileSkdVersion：|117117|117118|buildToolsVersion+"23.0.3“compileSdkVersion+23|117119|重试。|117120|117121|因此，这可能与Gradle插件的版本有关。|117122|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/saltares/libgdx-cookbook^0|T|F|0|0|0|2|8|0|0|9|C|W|H|1E|H|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|13|8|@]|9|@$A|14|B|15|1|16]]|C|$]]|$1|D|3|-4|5|6|7|17|8|@]|9|@]|C|$]]|$1|E|3|F|5|G|7|18|8|@$A|19|B|1A|H|I]]|9|@]|C|$]]|$1|J|3|K|5|G|7|1B|8|@]|9|@]|C|$]]|$1|L|3|M|5|G|7|1C|8|@$A|1D|B|1E|H|I]|$A|1F|B|1G|H|I]|$A|1H|B|1I|H|I]]|9|@]|C|$]]|$1|N|3|-4|5|6|7|1J|8|@]|9|@]|C|$]]|$1|O|3|P|5|6|7|1K|8|@]|9|@]|C|$]]|$1|Q|3|R|5|G|7|1L|8|@]|9|@]|C|$]]|$1|S|3|-4|5|6|7|1M|8|@]|9|@]|C|$]]|$1|T|3|U|5|6|7|1N|8|@]|9|@]|C|$]]|$1|V|3|-4|5|6|7|1O|8|@]|9|@]|C|$]]]|W|$X|$5|Y|Z|10|C|$11|12]]]]

I faced this same problem when trying to import the <a href="https://github.com/saltares/libgdx-cookbook" rel="nofollow">libgdx-cookbook</a> samples from "Libgdx Cross-platform Game Development Cookbook" into Android Studio 2.1.1. In my case, it was solved by simply:

<ul>
<li>importing the <code>/samples</code> project;</li>
<li>not upgrading the Gradle plugin when prompted;</li>
<li>updating <code>build.gradle</code> file under the android subproject to make it use the <code>buildToolsVersion</code> and <code>compileSkdVersion</code> that I had:

<pre><code>buildToolsVersion "23.0.3"
compileSdkVersion 23
</code></pre></li>
<li>trying again.</li>
</ul>

So it maybe has to do with the version of the Gradle plugin.

I wanted to open up and project in Android studio that I haven't worked on in a while, but when Android Studio tries to load the project it fails with this error message:

<pre><code>Error:(21, 0) Cannot set the value of read-only property 'jniFolders' on task ':android:packageDebug'.
</code></pre>

I click on the link to the <code>build.gradle</code> and I guess these lines are the problem ...

<pre><code>// needed to add JNI shared libraries to APK when compiling on CLI
tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask -&gt;
 pkgTask.jniFolders = new HashSet&lt;File&gt;()
 pkgTask.jniFolders.add(new File(projectDir, 'libs'))
}
</code></pre>

I see an answer here: <a href="https://stackoverflow.com/questions/33758421/google-appinvites-break-build">Google AppInvites break build</a> that says to ...

<blockquote>
 Fixed by adding this instead:

<pre><code>android {
 sourcesets {
 main {
 jniLibs.srcDir new File(buildDir, 'lib')
 {
 }
}
</code></pre>
</blockquote>

But the above answer is not very clear. I am not sure what line to change and the braces in the answer do not seem to match up.

I am at a total loss at what to do? Any help is appreciated.

Thanks
