问题描述
我有一个运行在Android上阿卡的一个问题。我的应用程序崩溃,一旦我启动它。我用阿卡2.3.5,Scaloid 3.5-10。
我开始我的 SignInActivity 的用
私人隐含VAL系统= ActorSystem(登入)//,这将引发上述错误
覆盖高清的onCreate(savedState:捆绑):单位= {
super.onCreate(savedState)
的setContentView(R.layout.signin)
VAL etMail =找到[EditText上(R.id.etMail)
VAL etPass =找到[EditText上(R.id.etPass)
找到[按钮](R.id.signInBtn).setOnClickListener(新OnClickListener {
覆盖高清的onClick(V:查看):单位= {
签到(etMail.text.toString,etPass.text.toString)
}

我真的不看这个定义怎么可能有任何问题的,但。也许这是一个的 proguard.cfg 的问题?
java.lang.NoSuchMethodError: scala.collection.immutable.StringLike.toString
有人有一种类似的问题,并与一些正确的ProGuard选择固定它。我确实有SeqLike部分在我ProGuard的,但也许别的东西丢失了。
有没有人一个想法是什么,我做错了?
PS:我做之前( - 不同阿卡问题虽然),但因为我不能得到工作,直到我现在贴出另一个阿卡问题
。我们可以通过观察从Maven仓库项目POM文件检查库的依赖
阿卡2.3.5 ,的
您可以看到,阿卡依靠斯卡拉库2.10.4和Scaloid上2.11.2。
如果你想在同一个项目/ classpath中使用它们,它们需要有依赖库相同版本的(理想情况下)或具有向后兼容的版本,以避免冲突的类路径。
I have a problem with running akka on android. My App crashes once I start it. I use Akka 2.3.5, Scaloid 3.5-10.
I start my SignInActivity with
private implicit val system = ActorSystem("signin") // this throws the error above
override def onCreate(savedState: Bundle): Unit = {
super.onCreate(savedState)
setContentView(R.layout.signin)
val etMail = find[EditText](R.id.etMail)
val etPass = find[EditText](R.id.etPass)
find[Button](R.id.signInBtn).setOnClickListener(new OnClickListener {
override def onClick(v: View): Unit = {
signIn(etMail.text.toString, etPass.text.toString)
}
})

I dont really see how this definition could be of any trouble though. Maybe it's a proguard.cfg problem?
java.lang.NoSuchMethodError: scala.collection.immutable.StringLike.toString
Someone had a kind of similar problem and fixed it with some correct proguard options. I do have the SeqLike Part in my proguard, but maybe something else is missing.
Has anyone an idea what I'm doing wrong?
PS: I did make a similiar post before (Akka on Android multiple reference.conf - different akka problem though) , but since I couldn't get working until now I posted another akka question.
One can check the library dependencies by looking at the project pom file from Maven repository:
You can see that Akka relies on scala-library 2.10.4 and Scaloid on 2.11.2.If you want to use them in the same project/classpath, they need to have the same version of dependency libraries (ideal case) or have backward compatible versions, in order to avoid classpath clashes.
