springboot 下 java 调用 apktool

  • 从官网下apktool.jar
  • 把依赖加入gradle dependencies 下添加
compile files('tool/apktool.jar')

但是apktool和springboot 里面的依赖冲突了 报 java.lang.NoSuchMethodError 从报错种找到相关包:

  • org.yaml.snakeyaml springboot 下是1.25 apktool 下是 1.12 好吧
  • 要么编译springboot 要么编译 apktool
  • 本着新版本应该会向老版本兼容的原则 尝试把 apktool 的 snakeyaml 从1.12提升到1.25

编译 apktool

snakeyaml: 'org.yaml:snakeyaml:1.12:android',
修改为
snakeyaml: 'org.yaml:snakeyaml:1.25:android',
  • gradlew.bat 秒闪后退出 看不清报错信息 修改gradlew.bat 在 :execute 后加 pause 看报错信息
:execute
@rem Setup the command line

set CLASSPATH=%APP_HOME%\gradle\wrapper\gradle-wrapper.jar

@rem Execute Gradle
"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %GRADLE_OPTS% "-Dorg.gradle.appname=%APP_BASE_NAME%" -classpath "%CLASSPATH%" org.gradle.wrapper.GradleWrapperMain %CMD_LINE_ARGS%
pause

  • 看到原因 Unsupported class file major version 57 好吧 jdk13 不支持 换jdk 8 重新编译成功

  • 文件在: brut.apktool/apktool-cli, 没看到这句话 纠结了1kb好久

After build completes you should have a jar file at: ./brut.apktool/apktool-cli/build/libs/apktool-xxxxx.jar

import brut.androlib.Androlib;
import brut.androlib.AndrolibException;
import brut.androlib.ApkDecoder;

        } catch (BrutException e) {
            e.printStackTrace();
        }
        System.out.println("buildApk done");
    }

            decoder.setOutDir(new File(appDir2));
            decoder.setApkFile(inFile);
            decoder.decode();
        } catch (IOException|AndrolibException | DirectoryException e) {
            e.printStackTrace();
        }
    }
}
