It seems to me that the proguard cache is not used correctly in the plug-in.

If I generate my app with clean and then android:install, then everything works ok. Proguard is executed, the app is installed and runs without problems.

However, if I leave out the clean and I don't change any code (e.g. I just change something in xml files), then proguard is not executed again, but the dex file is regenerated nevertheless without using proguard and apparently without including the scala library.

This is the output:

[info] [debug] cache hit, skipping proguard!
[info] [debug] Forcing clean dex
[info] Generating classes.dex
[info] Packaged: guidemate-debug-unaligned.apk (2,64MB)
[info] Debug package does not need signing: guidemate-debug-unaligned.apk
[info] zipaligned: guidemate-debug.apk
[info] Installing...
[info] [guidemate-debug.apk] Install finished: 2,64MB in 17,17s. 157,37KB/s

In tasks.scala (proguardTaskDef), there is this part:

if (inputs.proguardCache exists (_.exists)) {
    s.log.info("[debug] cache hit, skipping proguard!")
    None
}  

I think the problem could be that None is returned here instead of the cached jar file.

When I set it to false, it compiles but when the device tries to install the app, this error pops out: INSTALL_FAILED_INVALID_APK.

On N emulator: INSTALL_FAILED_INVALID_APK: Failed to extract native libraries, res=-2.

Or am I doing anything wrong?

Having these preconditions

• multiproject
• multi-dex enabled
• predex cache in place

Changing anything in project library and do run results in exception

java.lang.IllegalArgumentException: Source predex-libraries/classes-fea1db6a2e85fdeda8f2073688c847728e688fa4.jar/classes.dex 
and destination predex-libraries/classes-fea1db6a2e85fdeda8f2073688c847728e688fa4.jar/classes.dex must be different

See full showcase https://github.com/aafa/sbt-multiproject

Interestingly, doing reload + run (both each time) can make it work but not for long - I'm getting OutOfMemory exception after a while.

If I have a simple Activity that uses anonymous functions:

class MyActivity extends Activity with ViewFinder {
  override def onCreate(savedInstanceState: Bundle) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.main)

    val y = { (x: Int) => x + 1 }

    Log.i("foo", y(4).toString)
  }
}

my app crashes with :

Hi,

Your plugin is awesome but sometimes, without any reason it doesn't work.

Sometimes, when I launch the compilation, I get a crash from SBT telling me that I have more than 65K methods.

Then I type clean in the console, retry and it just works. Next compilation works, and so on for several hours, and for no obvious reason, the same error comes back. I make no modification to the sbt file or anything like this. It just kind of random (or there is a cause I have not yet found).

Moreover I have a huge proguard file. I know it s applied automatically (when proguard is used) because otherwise I would get lots of warnings.

Here is my plugin sbt file

addSbtPlugin("com.hanhuy.sbt" % "android-sdk-plugin" % "1.2.2")

addSbtPlugin("com.hanhuy.sbt" % "sbt-idea" % "1.6.0")

addSbtPlugin("com.timushev.sbt" % "sbt-updates" % "0.1.2")

and here is my build.sbt file

// so we can use keywords from Android, such as 'Android' and 'proguardOptions'
import android.Keys._
import android.Dependencies.{aar,apklib}

// load the android plugin into the build
android.Plugin.androidBuild


// project name, completely optional
name := "OBackup"

// pick the version of scala you want to use
scalaVersion := "2.10.2"

// scala 2.10 flag for feature warnings
scalacOptions in Compile += "-feature"

// for non-ant-based projects, you'll need this for the specific build target:
platformTarget in Android := "android-19"

Do you have an idea about the reason?

Regards

We are using android-sdk-plugin in a new Android project.

In order to avoid 65K methods error, we have set up our project to use a multidex configuration and we have disabled the proguardCache, setting proguardCache in Android := Seq.empty

Here more info about our config:

proguardScala in Android := true,
useProguard in Android := true,
proguardCache in Android := Seq.empty

....

dexMaxHeap in Android := "2048m",
dexMulti in Android := true,
dexMinimizeMainFile in Android := true,
dexMainFileClasses in Android := multiDexClasses

Since we use multiDex, incremental=false is always shown in console and the compilation time is too long.

Are we missing anything in our config for using multiDex with incremental?

Thanks!

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.x" on path: ...

I'm using 1.6.6 and it seems this old exception is back. It occurs ~50% of the times when launching apps. And when that happens I have to do a clean and rebuild which is annoying.

Could you take a look?

Hi, A simple app with android-sdk-plugin works fine. The problems start when trying to add javacv (bindings to opencv). Below is given my sbt file. At first try I was able to install the app on device but it crashed with AndroidRuntime(20677): java.lang.NoClassDefFoundError: org.bytedeco.javacpp.opencv_core$Rect. After this I can not install the app at all and Proguard is barking (1500 lines worth of complaints). Any ideas? Can the problem be related to "maven-plugin"?

import android.Keys._

android.Plugin.androidBuild

platformTarget in Android := "android-16"

scalaVersion := "2.11.6"

classpathTypes += "maven-plugin"

libraryDependencies ++= Seq(
  "org.bytedeco"                 % "javacpp"         % "0.11",
  "org.bytedeco"                 % "javacv"          % "0.11",
  "org.bytedeco.javacpp-presets" % "opencv" % ("2.4.11-0.11") classifier "",
  "org.bytedeco.javacpp-presets" % "opencv" % ("2.4.11-0.11") classifier "android-arm"
)

name := "hello-world"

javacOptions in Compile ++= Seq("-source", "1.7", "-target", "1.7")
'''

Both support-v4 and support-v13, since version 20.0.0. What a pity! I am not sure, but this code will probably have to be modified.

There is also another problem: in Macroid I was happily including the dependencies the simple way:

libraryDependencies ++= Seq(
  "com.google.android" % "android" % "4.1.1.4" % "provided",
  "com.android.support" % "support-v13" % "19.1.0"
)

Now that I have to unpack the AAR, it would make more sense to just use the plugin. However I don’t rely on resource ids, don’t have an AndroidManifest.xml, don’t want to publish as AAR instead of plain Scala library. Do you think I actually should? Or would it be possible to include the plugin without all that and just use aar to extract the jar from the AAR?

Trying to build a Android project with a Android library and a Android project. Both containing scala code.

I have followed this https://gist.github.com/pfn/5872770 and created this Build.scala

import sbt._ import sbt.Keys._

import android.Keys._

object MyProjectBuild extends Build {

// meta project lazy val root = Project(id = "ABM", base = file(".")) settings(Seq( packageT in Compile <<= packageT in Android in ABM, packageRelease <<= packageRelease in Android in ABM, packageDebug <<= packageDebug in Android in ABM, run <<= run in Android in ABM ) ++ android.Plugin.androidCommands: _* ) aggregate(ABM, GR)

// android application project lazy val ABM = Project(id = "Custom", base = file("ABM")) settings( android.Plugin.androidBuild(GR) ++ Seq( proguardScala in Android := true, proguardOptions in Android ++= Seq( "-dontobfuscate", "-dontoptimize" ) ): _*) dependsOn GR

val GenericRace = Project(id = "GR", base = file("GR")) settings ( Seq( scalacOptions in Compile += "-deprecation", javacOptions in Compile += "-deprecation", libraryDependencies ++= Seq(/* "com.viewpagerindicator" % "library" % "2.4.1" % "provided", "com.android.support" % "support-v4" % "18.0.0", "com.android.support" % "appcompat-v7" % "18.0.0"_/) ) ++ android.Plugin.androidBuild: __) }

But whenever i run the application on a device i get Class not found exception

Could not find class 'scala.Some' or java.lang.NoClassDefFoundError: scala.concurrent.ExecutionContext

These files are not in the classes.dex.

I'm trying to build .aar file with sbt but I'm getting this error:

[error] Not a valid key: package-release (similar: package-name, set-release, packageName)
[error] android:package-release
[error]  

I already changed

enablePlugins(AndroidApp) line to enablePlugins(AndroidLib) but still get this error.

To build aar I'm using sbt clean android:package-release command.

How can I fix this?

Is there any chance that someone could look into supporting scala 3 projects with sbt-android?

Starting with the sbt-android example projects, and adding addSbtPlugin("ch.epfl.lamp" % "sbt-dotty" % "0.5.0") and scalaVersion := "3.0.0-M3" I haven't been able to get this to work yet.

Has anyone been able to do this successfully yet? Is there more migration work that needs to be done to make this plugin support scala 3?

Upgrade the build to sbt 1.2.8 in order to support the release of an sbt 1.x version of this plugin.

Bump the version to 2.0.0-SNAPSHOT and remove most things deprecated in the 1.x releases of the plugin.

Parallelize build across scripted tests so build time on Travis isn't pushing the 50 minute limit.

Huge props to @soc for doing a bunch of work to get this started.
