wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# MQTT # Android Mqtt Client
基于[mosquitto](https://github.com/eclipse/mosquitto)的android mqtt客户端
* 使用[mosquitto/lib](https://github.com/eclipse/mosquitto/tree/master/lib)的代码，用c++封装接口
* 对外提供java接口，简单易用
* 支持OpenSSL加密
* 实现订阅、解除订阅、发布消息等功能
MQTT安卓客户端 ## 接口
MqttClient.java
```java
/**
* 获取单例
*/
public static MqttClient getInstance()
```
```java
/**
* 启动mqtt服务
*/
public void start(@NonNull String host, int port, @NonNull String uuid, boolean clearSession)
public void start(@NonNull String host, int port, @NonNull String uuid, boolean clearSession, @NonNull String caFilePath, @NonNull String username, @NonNull String password)
```
```java
/**
* 重连服务
*/
public void reconnect()
```
```java
/**
* 订阅主题
*/
public void subscribe(String topic)
public void subscribe(String topic, int qos)
public void subscribe(List<String> topicList)
public void subscribe(List<String> topicList, List<Integer> qosList)
```
```java
/**
* 解除订阅
*/
public void unsubscribe(String topic)
public void unsubscribe(List<String> topicList)
```
```java
/**
* 发布消息
*/
public void publish(String topic, String message)
public void publish(String topic, String message, int qos)
```
```java
/**
* mqtt事件回调接口
*/
public interface MqttCallback {
@WorkerThread
void onMessage(@NonNull String topic, @NonNull String message);
@WorkerThread
void onLog(String str);
}
```
```java
/**
* 设置mqtt事件回调
*/
public void setOnMqttCallback(@Nullable MqttCallback callback)
```
## 使用
```
- 导入Module: Android Studio -> File -> New -> Import Module -> 选中“library”文件夹
- 修改app/build.gradle文件，添加ndk abiFilters设置
android {
...
defaultConfig {
...
ndk {
abiFilters 'armeabi-v7a', 'x86', 'arm64-v8a'
}
}
}
- 添加依赖
dependencies {
implementation project(':library')
}
```
## 编译问题
因为默认支持OpenSSL，依赖静态库只添加了三个abi版本，所以项目编译默认只支持```'armeabi-v7a', 'x86', 'arm64-v8a'```，如需支持其他cpu abi，请自行编译OpenSSL静态库
* 把```libssl.a libcrypto.a```文件添加到```/library/src/main/jni/lib```目录下，并用文件夹区分abi类型
* 修改```library/build.gradle```，添加对应的abi类型
* 修改```app/build.gradle```，添加对应的abi类型
## 禁用OpenSSL
修改```/library/src/main/jni/Android.mk```文件，注释掉下面的代码
```
...
# ssl lib
#include $(CLEAR_VARS)
#LOCAL_MODULE := ssl
#LOCAL_SRC_FILES := lib/$(TARGET_ARCH_ABI)/libssl.a
#include $(PREBUILT_STATIC_LIBRARY)
# crypto lib
#include $(CLEAR_VARS)
#LOCAL_MODULE := ssl_crypto
#LOCAL_SRC_FILES := lib/$(TARGET_ARCH_ABI)/libcrypto.a
#include $(PREBUILT_STATIC_LIBRARY)
...
#LOCAL_CFLAGS += -DWITH_TLS_PSK
#LOCAL_CFLAGS += -DWITH_TLS
...
# link lib
#LOCAL_STATIC_LIBRARIES := ssl ssl_crypto
...
```
## 例子
app module只实现了简单的调用，相关日志输出到了logcat

/** \brief Represents a <a HREF="http://www.json.org">JSON</a> value.
*
* This class is a discriminated union wrapper that can represents a:
* - signed integer [range: Value::minInt - Value::maxInt]
* - unsigned integer (range: 0 - Value::maxUInt)
* - double
* - UTF-8 string
* - boolean
* - 'null'
* - an ordered list of Value
* - collection of name/value pairs (javascript object)
*
* The type of the held value is represented by a #ValueType and
* can be obtained using type().
*
* Values of an #objectValue or #arrayValue can be accessed using operator[]()
* methods.
* Non-const methods will automatically create the a #nullValue element
* if it does not exist.
* The sequence of an #arrayValue will be automatically resized and initialized
* with #nullValue. resize() can be used to enlarge or truncate an #arrayValue.
*
* The get() methods can be used to obtain default value in the case the
* required element does not exist.
*
* It is possible to iterate over the list of member keys of an object using
* the getMemberNames() method.
*
* \note #Value string-length fit in size_t, but keys must be < 2^30.
* (The reason is an implementation detail.) A #CharReader will raise an
* exception if a bound is exceeded to avoid security holes in your app,
* but the Value API does *not* check bounds. That is the responsibility
* of the caller.
