MSDK -- Android-ActivationAndBindingDemo代码跟读

“MSDK的激活和绑定已经弃用，现在只需要完成MSDK注册就可以使用MSDK的功能”

一、概述

这边文章主要讲一下MSDK激活和绑定示例代码跟读，初步了解SDK的绑定登录等功能实现原理即状态监听。

二、代码

安装SDK代码：MApplication.java

注册App和连接飞机代码：ConnectionActivity.java，DemoApplication.java

安装SDK，注册，连接飞机等相关代码和上篇MSDK -- Android-ImportAndActivateSDKInAndroidStudio代码跟读文章过程基本类似，这边不再做重复解读。

主代码： MainActivity.java

实现了UI界面初始化，账号登录登出功能，登录状态检查，绑定状态检查。

UI界面初始化：

使用了R.layout.activity_main布局初始化activity界面：

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

initUI();
initData();

}

对登录登出按钮组件进行绑定，激活和绑定信息状态的text的显示组件绑定：

private void initUI(){

bindingStateTV = (TextView) findViewById(R.id.tv_binding_state_info);
appActivationStateTV = (TextView) findViewById(R.id.tv_activation_state_info);
loginBtn = (Button) findViewById(R.id.btn_login);
logoutBtn = (Button) findViewById(R.id.btn_logout);
loginBtn.setOnClickListener(this);
logoutBtn.setOnClickListener(this);

}

登入登出按钮事件绑定：

@Override
public void onClick(View v) {

switch (v.getId()) {
case R.id.btn_login:{
loginAccount();
break;
}
case R.id.btn_logout:{
logoutAccount();
break;
}
default:
break;
}
}

数据的状态监听，实现了app激活状态，绑定状态的MSDK代码层面的回调显示并实时进行回调刷新：

1.App激活状态监听AppActivationStateListener，并通过状态变更回调实时更新显示到text中

appActivationStateTV.setText("" + appActivationState);

2.飞机绑定状态监听回调：AircraftBindingStateListener，并通过状态变更回调实时更新显示到text中

bindingStateTV.setText("" + bindingState);

private void setUpListener() {
// Example of Listener
activationStateListener = new AppActivationState.AppActivationStateListener() {
@Override
public void onUpdate(final AppActivationState appActivationState) {
MainActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
appActivationStateTV.setText("" + appActivationState);
}
});
}
};

bindingStateListener = new AircraftBindingState.AircraftBindingStateListener() {

@Override
public void onUpdate(final AircraftBindingState bindingState) {
MainActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
bindingStateTV.setText("" + bindingState);
}
});
}
};
}

private void initData(){
setUpListener();

appActivationManager = DJISDKManager.getInstance().getAppActivationManager();

if (appActivationManager != null) {
appActivationManager.addAppActivationStateListener(activationStateListener);
appActivationManager.addAircraftBindingStateListener(bindingStateListener);
MainActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
appActivationStateTV.setText("" + appActivationManager.getAppActivationState());
bindingStateTV.setText("" + appActivationManager.getAircraftBindingState());

}
});
}
}

DJI账号的登入登出功能：

登入：loginAccount

private void loginAccount(){

UserAccountManager.getInstance().logIntoDJIUserAccount(this,
new CommonCallbacks.CompletionCallbackWith<UserAccountState>() {
@Override
public void onSuccess(final UserAccountState userAccountState) {
showToast("Login Success");
}
@Override
public void onFailure(DJIError error) {
showToast("Login Error:"
+ error.getDescription());
}
});

}

登出：logoutAccount

private void logoutAccount(){
UserAccountManager.getInstance().logoutOfDJIUserAccount(new CommonCallbacks.CompletionCallback() {
@Override
public void onResult(DJIError error) {
if (null == error) {
showToast("Logout Success");
} else {
showToast("Logout Error:"
+ error.getDescription());
}
}
});
}

}
