Android Studio + dropbox-android-sync-sdk-1.1.2

Question

Can someone explain how I can enable the Dropbox SDK in Android Studio? On the Dropbox website, I found information for the Eclipse IDE. I tried to include it in Android Studio, but with no result. The IDE cannot find the com.dropbox.sync class.

Answer 1

I have never used Android Studio before, so I had to look for it ... these are good instructions for adding an external library to an Android Studio project: How do I add a library project in Android Studio?

After that, with the Dropbox Android Sync SDK, I nested the contents of the libs in the Android SDK into the libs in my Android project, and then added this line to build.gradle (inside dependencies ):

 compile files('libs/dropbox-sync-sdk-android.jar') 

It seemed to work for me. If you tried this and it didn’t work (or if you tried something else), provide some details.

EDIT Paste my answer from Android and DropboxSync Library for completeness:

I found this SO answer useful: enable .so library in apk in android studio

Part of my build.gradle file now looks like this, and my application starts up successfully:

 dependencies { compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar') compile fileTree(dir: 'libs', include: '*.jar') } task nativeLibsToJar( type: Zip, description: 'create a jar archive of the native libs') { destinationDir file("$buildDir/native-libs") baseName 'native-libs' extension 'jar' from fileTree(dir: 'libs', include: '**/*.so') into 'lib/' } tasks.withType(Compile) { compileTask -> compileTask.dependsOn(nativeLibsToJar) } 

Answer 2

The official solution did not work for me. And I notice "Compile" in tasks.withType (Compile) has an obsolete warning.

The following lines in build.gradle work:

 dependencies { compile files('libs/dropbox-sync-sdk-android.jar') } android { tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask -> pkgTask.jniFolders = new HashSet<File>(); pkgTask.jniFolders.add(new File(projectDir, 'libs')); } } 

Place the 'libs' folder from Dropbox sdk at the same level with the 'build' and 'src' folders.

You have the official answer on the Dropbox Developer Blog:

It's funny that a question interesting enough for the api developers answer is rated negatively ...
