APK 源码预置到ROM时，编译成功，运行失败
    JNI_OnLoad returned bad version (-1)

    问题：源码编译时自动混淆了
    解决方法：
    mk中配置混淆脚本。

    1. # 代码混淆
    2. LOCAL_PROGUARD_FLAG_FILES := proguard-rules.pro

    混淆配置 proguard-rules.pro

    1. # Add project specific ProGuard rules here.
    2. # You can control the set of applied configuration files using the
    3. # proguardFiles setting in build.gradle.
    4. #
    5. # For more details, see
    6. #   http://developer.android.com/guide/developing/tools/proguard.html
    8. # If your project uses WebView with JS, uncomment the following
    9. # and specify the fully qualified class name to the JavaScript interface
    10. # class:
    11. #-keepclassmembers class fqcn.of.javascript.interface.for.webview {
    12. #   public *;
    13. #}
    15. # Uncomment this to preserve the line number information for
    16. # debugging stack traces.
    17. -keepattributes SourceFile,LineNumberTable
    19. # If you keep the line number information, uncomment this to
    20. # hide the original source file name.
    21. -renamesourcefileattribute SourceFile
    23. -ignorewarnings
    24. -keepattributes Signature,*Annotation*
    26. # 混淆后就会生成 类名->混淆后类名 的映射关系
    27. -verbose
    28. -printmapping mapping.txt
    31. # 不做预检验，preverify是proguard的四个步骤之一
    32. # Android不需要preverify，去掉这一步可以加快混淆速度
    33. -dontpreverify
    36. # 保留所有的本地native方法不被混淆
    37. -keepclasseswithmembernames class * {
    38.     native <methods>;
    39. }
    42. ### common-log
    43. -dontwarn ishawn.common.log.**
    44. -keep class ishawn.common.log.** { *;}
    45. -dontwarn me.pqpo.librarylog4a.**
    46. -keep class me.pqpo.librarylog4a.** { *;}
