java.lang.NoSuchMethodError: no static or non-static method 解决方法

最近在调试JNI的时候报了一个莫名其妙的错误，纠结了很久，现象是同一种类型的函数可以注册成功，不同类型的就会抛出一项异常：

E AndroidRuntime: java.lang.NoSuchMethodError: no static or non-static method "Lcom/sprd/validationtools/phasecheckjni/PhaseCheckJNI;.eng_writephasecheck(III)I"
E AndroidRuntime: at java.lang.Runtime.nativeLoad(Native Method)

E AndroidRuntime: at dalvik.system.NativeStart.main(Native Method)

最后发现这是由于编译器优化引起的，需要在Android.mk里面加入如下属性即可：

LOCAL_PROGUARD_ENABLED:= disabled

问题解决~~

结论：Android jni中慎用Proguard
