1、问题

 

chenyu@chenyu:~/Android_dev/Test/app/jni$ ndk-build
[armeabi] Compile thumb  : FirstJni <= JniClient.c
/home/chenyu/Android_dev/Test/app/jni/JniClient.c: In function 'callMethod2':
/home/chenyu/Android_dev/Test/app/jni/JniClient.c:74:18: error: void value not ignored as it ought to beint result = (*env)->CallVoidMethod(env, jobj, method2, 5, 5);^
make: *** [/home/chenyu/Android_dev/Test/app/obj/local/armeabi/objs/FirstJni/JniClient.o] Error 1

 

 

 

2、原因

 因为我写得callMethod2方法里面是这样写的

 

int result = (*env)->CallVoidMethod(env, jobj, method2, 5, 5);

特码很明显啊，我有返回值了，还调用（*env）->CallVoidMethod(env, jobj , method2, 5, 5);

 

自己傻逼啊，这个本地方法明显没有返回值
