jni 常见错误收集

1. 写错了load的library

2. Android.mk文件编写错误
        /jni/Android.mk:4: *** missing separator.  Stop.

3. LOCAL_MODULE配置不能有扩展名
        //jni/Android.mk:hello.so: LOCAL_MODULE_FILENAME must not contain a file extension

        objs/hello/helo.o'.  Stop.

        添加多cpu平台的支持 APP_ABI := armeabi armeabi-v7a x86

6. c语言方法名称错误，导致java代码无法寻找到c代码
