### Android Studio 1.1 with blank Android project woes

I am trying to use the gradle/artifact method in the tutorials at:

http://wiki.ros.org/android/Tutorials/hydro/Installation%20-%20Android%20Studio%20Development%20Environment

I have a lot of problems trying to build a RosJava 'blank' Android Studio project both on Windows and Ubuntu.

By 'blank' Android Studio project, I did the following: Fresh install of Android Studio (1.1) and SDK (24.1.2) Project Close if one open, or ... 'Start a new Android Studio Project' File > New Project... > Phone and Tablet , API 18 - 4.3 Jelly Bean > Blank Activity > Finish It complains about rendering problems, but once the Gradle build completes it is okay.

Build and run the project, it works. See the 'Hello World' on the blank App.

In the project explorer, open 'Gradle Scripts > build.gradle (Module: app), and add lines so the file 'dependencies' section is replaced with the following 2 sections, repositories and dependencies:

repositories {

maven {

url 'https://github.com/rosjava/rosjava_mvn_repo/raw/master'

}

mavenCentral()


}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

compile 'com.android.support:appcompat-v7:22.0.0'

//compile 'org.ros.android_core:android_honeycomb_mr2:[0.1,0.2)'

//compile 'org.ros.rosjava_core:rosjava:[0.1,0.2)'


}

Click the 'Sync Now' in the yellow band near the top, and wait for the Gradle task to finish

Do Build > ReBuild Project Again the project runs with no problem.

On Windows, I had to remove a line in AndroidManifest.xml:

Uncomment the 'compile ... gingerbread line, in Build.gradle: app click the yellow bar to Sync Now rebuild the project, and see the errors The errors are below:
