【2】Android.mk文件内容
1 LOCAL_PATH := $(call my-dir) 2 3 include $(CLEAR_VARS) 4 5 LOCAL_LDLIBS := -lz 6 7 LOCAL_MODULE := hello-jni 8 LOCAL_SRC_FILES := hello-jni.c 9 10 include $(BUILD_SHARED_LIBRARY)
【3】Application.mk的代码
1 APP_ABI := armeabi armeabi-v7a x86 mips 2 APP_PLATFORM := android-14
【4】需进行配置----在build.gradle中做一个资源路径指定即可：
1 // build.gradle 2 android { 3 // 4 //... 5 sourceSets { 6 main { 7 //你的源码目录 8 jniLibs.srcDirs 'src/main/libs' 9 //此处有些是 10 jniLibs.srcDirs './libs' 11 12 } 13 } 14 }
【5】在Android NDK开发中，经常需要在C代码中回调JAVA中的方法
这时就需要知道java方法的方法名和方法签名。
使用javap -s 命令可以完成。
查看系统java系统方法
javap -s java.lang.String
查看自定义类：
转到class目录下执行：
javap -s com.example.ndksocket.MainActivity
【6】Android studio生成的class文件在哪里查看
CCallBackJava\app\build\intermediates\classes\debug\com\example\ccallbackjava
【7】String 转换为char的代码：
1 /** 2 * 把一个jstring转换成一个c语言的char* 类型. 3 */ 4 char* _JString2CStr(JNIEnv* env, jstring jstr) { 5 char* rtn = NULL; 6 jclass clsstring = (*env)->FindClass(env, "java/lang/String"); 7 jstring strencode = (*env)->NewStringUTF(env,"GB2312"); 8 jmethodID mid = (*env)->GetMethodID(env, clsstring, "getBytes", "(Ljava/lang/String;)[B"); 9 jbyteArray barr = (jbyteArray)(*env)->CallObjectMethod(env, jstr, mid, strencode); // String .getByte("GB2312"); 10 jsize alen = (*env)->GetArrayLength(env, barr); 11 jbyte* ba = (*env)->GetByteArrayElements(env, barr, JNI_FALSE); 12 if(alen > 0) { 13 rtn = (char*)malloc(alen+1); //"\0" 14 memcpy(rtn, ba, alen); 15 rtn[alen]=0; 16 } 17 (*env)->ReleaseByteArrayElements(env, barr, ba,0); 18 return rtn; 19 }
【8】LOG打印需要的代码
1 #include <android/log.h> 2 #define LOG_TAG "System.out" 3 #define LOGD(...) __android_log_print(ANDROID_LOG_DEBUG, LOG_TAG, __VA_ARGS__) 4 #define LOGI(...) __android_log_print(ANDROID_LOG_INFO, LOG_TAG, __VA_ARGS__) 5 //使用实例 6 LOGD("length = %d",length); 7 //修改Android.mk内容 8 LOCAL_LDLIBS := -llog
