如何將Jess（.jar文件）庫轉換為.dex文件，或在Android上運行Java類文件？

Question

我試圖在終端IDE（android）上運行Jess，但是當我嘗試運行以下命令時：

terminal++@192.168.0.102:~/sdcard/myJess$ dx --dex --output=jess.dex Jess71p2/lib/jess.jar

我收到消息：

warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)

我嘗試了其他方法，例如通過ssh連接到其他計算機，但是它不可用並且無法像本地一樣快速。 有誰知道解決方案或其他方法？

Answer 1

Jess 7與Android不兼容。 傑西8，將會在今天的任何一天發布。 因此，請留意www.jessrules.com。

Answer 2

您需要在dx選項中添加--no-strict ，並且如果您遇到OutOfMemory異常，則應編輯 dx腳本並擴展內存范圍：

dalvikvm -Xss262912 -Xmx500M -cp $APK com.spartacusrex.spartacuside.external.dx $@

將-Xmx500M更改為所需的內存

也就是說，直到停止接收OOM異常為止。

對我來說，從JDK的tools.jar中-Xmx900M tools.jar時，限制是-Xmx900M此后，由於我的手機有大約900-990MB的可用空間，因此無法分配更多的內存。

• 解壓縮類文件后的下一步是重新打包jess.jar中所有剩余的資源文件，因為dex文件沒有資源。
• 使用java命令或winrar或任何文件瀏覽器觀察該jar文件的內容，並找到資源文件夾。 您可能會發現多個這樣的resources文件夾，並將其全部提取出來。

• 確保您的dex文件具有名稱classes.dex然后將所有文件重新打包到一個新的jess_for_android.jar中，並將所有資源與原始jess.jar文件中的資源保持在同一目錄樹中

• 最后，當您嘗試使用它時，請使用dalvikvm命令，而不要使用java否則（可能）會出現錯誤：

   dalvikvm -cp path_To_your_repacked_jar Main_className $@ 

內存選項-Xss和-Xmx是可選的。
