Hi,
I'm learning both Android and Scala. Now I'm trying to add an ActionBar.
The app works when I use ant. But when I use pfn's [android-sdk-plugin], the
activity cannot be displayed properly. ActionBar is displayed but it fills the
whole screen.
Here is how I create an ActionBar app using sbt.
# Using Ant
First, I create a new project "action-bar-demo" in its parent directory
"mydemo".
$ mkdir mydemo && cd mydemo
$ android create project -t android-19 -p action-bar-demo -k
com.example.actionbardemo -a ActionBarDemo
$ cd ..
Then I copy v7-appcompat code into "mydemo".
$ cp -R ${ANDROID_HOME}/extras/android/support/v7/appcompat .
$ android update lib-project -p appcompat
Set `minSdkVersion` to 7, add a theme, extends
`android.support.v7.app.ActionBarActivity`, and referencing the library
project.
$ cd action-bar-demo
$ edit AndroidManifest.xml
$ edit src/com/example/actionbardemo/ActionBarDemo.java
$ android update project -p . -l ../appcompat
Compile and install.
$ ant debug install
Then run the app on device, it *works*.
# Using Sbt
Next, I create `Build.scala` and `plugins.sbt` in directory `project`.
## `plugins.sbt`
```
addSbtPlugin("com.hanhuy.sbt" % "android-sdk-plugin" % "1.2.3")
```
## `Build.scala`
I borrowed `Build.scala` from the plugin's [wiki].
BTW, it seems the wiki page is outdated:
1. `import AndroidKeys._` should be `import android.Keys._`.
2. `AndroidSdkPlugin.androidBuildSettings` should be
`android.Plugin.androidBuild`.
Finally, the content of `project/Build.scala` is:
```
import sbt._
import sbt.Keys._
import android.Keys._
object MyProjectBuild extends Build {
// meta project
lazy val root = Project(id = "meta-project", base = file(".")) settings(
packageT in Compile <<= packageT in Android in myproject,
packageRelease <<= packageRelease in Android in myproject,
packageDebug <<= packageDebug in Android in myproject
) aggregate(myproject, appcompat)
// android application project
lazy val myproject = Project(id = "myproject", base =
file("action-bar-demo")) settings(
appSettings:_*
)
val appcompat = Project(id = "appcompat",
base = file("appcompat")) settings(
android.Plugin.androidBuild: _*)
lazy val appSettings = android.Plugin.androidBuild :+
(name := "actionbardemo") :+
(compile in Compile <<= compile in Compile
dependsOn(packageT in Compile in appcompat))
}
```
Run the app on device, the ActionBar cannot be displayed properly.
$ sbt myproject/android:run
Is there any problem in my `Build.scala`? Please help me. Thank you.
