Android Studio integration with MobileFirst

Question

I have several problems running the native android example (Hello World) from IBM MobileFirst Studio (Eclipse Kepler) with an integration with Android Studio.

I followed all the steps in the documentation including all prerequisites here . When I run the application via the context menu: Right click on the application Run As > Android Studio Project . MobileFirst launches Android Studio, but the application remains with the following errors and warnings in AndroidStudio configuration:

1. Warning: AndroidStudio asks me to migrate to Gradle. I ignore this migration, because I have found that the compilation and deployment Gradle is quite delayed.
2. I select my project and pressed F4, in the Project > Project SDK option, the SDK is invalid, I select one valid.
3. In the Modules > Modules SDK option, the SDK is invalid, I select one favorite, same as above.
4. In the Libraries option, there are 3 libraries not found, so I remove the references.
5. In SDK option I select only the API 10.

At this point the application compiles and deploys the emulator correctly. When running, the IBM splash screen appears and closes immediately without entering the application.

The following appears on the logcat:

Another problem is that when I return to launch the application from MobileFirst, AndroidStudio opens and asks me reload modified files (from MobileFirst) externally, apparently not synchronized and changes to the settings disappear.

Anyone know how to solve these problems?

I should clarify that for AndroidStudio be executed, I had to install a Fix Pack MobileFirst.

Sorry for my English.

Thanks for your opinions and help.

Answer 1

Gradle is not supported by Worklight projects for Android at this time.

For the rest of the issues, I got it to work by:

1. Specifying an SDK

2. In app-name.iml, remove the scope from the following line:

    <orderEntry type="library" name="libs" level="project" /> 

Looks like something has changed recently in Android Studio because projects used to work out of the box with it (except for Gradle, which is not supported at this time).

Try the above.
