android aidl接口初步了解

摘要: 本文以最简单的代码解说aidl，本文是androidstudio开发。。app指的是创建项目。。mylibrary是依赖工程，大致思路：在项目中创建一个依赖工程，在依赖工程中创建aidl文件（记得重新构建工程），创建service服务类，注册服务，在app类中创建aidl文件(必须和依赖工程的aidl文件一致)，开启服务。。得到数据(google在5.0之前。。bindService开启是隐式意图；5.0则要设置为显示意图。。不然会异常退出)；

//app类

onclick.setOnClickListener(new View.OnClickListener() {
@Override

Intent intent = new Intent();

//5.0版本则设置为显示意图
//否则设置为Intent intent = new Intent("you action("参考mylibrary清单文件")")
intent.setClass(MainActivity.this, MAIDLService.class);
bindService(intent, connection, BIND_AUTO_CREATE);

}
});
}

ServiceConnection connection = new ServiceConnection() {

Log.e("张三",aidlone.getName().length()+"");
titles.setText(aidlone.getName());

} catch (Exception e) {
e.printStackTrace();
}
}

//
@Override

}

//app中的aidl

// Aidlone.aidl
package com.qudoulicai.www.aidltest;

// Declare any non-default types here with import statements

//mylibrary依赖包

//服务类

}
};

@Nullable

}
}

//aidl文件

// Aidlone.aidl
package com.qudoulicai.www.mylibrary;

// Declare any non-default types here with import statements

}

//mylibrary清单文件

<service

//app中的布局文件

//ps：有不足之处请多包涵。。。创建依赖文件记得引用文件“

compile project(':"you libray name"')
