运行官方的helloworld.smali报错找不到类，好奇怪，经过一番google后才发现，原来要在root权限下才可以执行。

报错：

Dalvik VM unable to locate class 'Helloworld'java.lang.NoClassDefFoundError: Helloworldat dalvik.system.NativeStart.main(Native Method)Caused by: java.lang.ClassNotFoundException: Didn't find class "Helloworld" on path: /data/local/HelloWorld.zip

smali代码

.class public LHelloWorld;#Ye olde hello world application#To assemble and run this on a phone or emulator:##java -jar smali.jar -o classes.dex HelloWorld.smali#zip HelloWorld.zip classes.dex#adb push HelloWorld.zip /data/local#adb shell dalvikvm -cp /data/local/HelloWorld.zip HelloWorld##if you get out of memory type errors when running smali.jar, try#java -Xmx512m -jar smali.jar HelloWorld.smali#instead.super Ljava/lang/Object;.method public static main([Ljava/lang/String;)V    .registers 2    sget-object v0, Ljava/lang/System;->out:Ljava/io/PrintStream;    const-stringv1, "Hello World!"    invoke-virtual {v0, v1}, Ljava/io/PrintStream;->println(Ljava/lang/String;)V    return-void.end method
