[android]导出apk报错 Conversion to Dalvik format failed with error 1

 

 

在项目加入混淆之后，导出都会提示

 

Conversion to Dalvik format failed with error 1

 

解决方法：

 

在 android-sdk-windows\tools\proguard\bin目录找到：

proguard.bat

用记事本打开，内容如下：

@ECHO OFF

REM Start-up script for ProGuard -- free class file shrinker, optimizer,
REM obfuscator, and preverifier for Java bytecode.

rem Change current directory and drive to where the script is, to avoid
rem issues with directories containing whitespaces.
cd /d %~dp0

IF EXIST "%PROGUARD_HOME%" GOTO home
SET PROGUARD_HOME=..
:home

set java_exe=
call "%PROGUARD_HOME%"\..\lib\find_java.bat

call %java_exe% -jar "%PROGUARD_HOME%"\lib\proguard.jar %*

 

把

call %java_exe% -jar "%PROGUARD_HOME%"\lib\proguard.jar %*

改为：

call %java_exe% -jar "%PROGUARD_HOME%"\lib\proguard.jar %1 %2 %3 %4 %5 %6 %7 %8 %9

 

即可！
