android极光推送初步了解

推送可以及时,主动的与用户发起交互

(1)继承jar包,照示例AndroidManifest.xml添加.

(2)自定义MyApp继承自Application,在onCreate方法中调用JPushInterface.init(MainActivity.this);

或者在Activity的onCreate中调用.

(3)另外,在activity的onResume方法要调用JPushInterface.onResume(this);否则,推送不会出现,

在onPause中调用JPushInterface.onPause(this);

这样,可以通过服务器往安装了App的所有用户发送一条推送.

通过Alias往客户端发送信息.

在客户端的onCreate中

JPushInterface.setAlias(MainActivity.this, "aa", new TagAliasCallback() {

                    @Override

                    public void gotResult(int arg0, String arg1, Set<String> arg2) {

                        Log.e("info",arg1+"-----------");

                        //arg1是tag

                    }

                });

这句就是将"aa"当成该设备的别名,达到往指定客户端发送消息的目的.

别名和签名设置的异常处理

有时会因为网络原因,有一定几率设置别名或标签失败.

privatevoidsetAlias() {

EditText aliasEdit = (EditText) findViewById(R.id.et_alias);

String alias = aliasEdit.getText().toString().trim();

if(TextUtils.isEmpty(alias)) {

Toast.makeText(PushSetActivity.this,R.string.error_alias_empty, Toast.LENGTH_SHORT).show();

return;

}

if(!ExampleUtil.isValidTagAndAlias(alias)) {

Toast.makeText(PushSetActivity.this,R.string.error_tag_gs_empty, Toast.LENGTH_SHORT).show();

return;

}

// 调用 Handler 来异步设置别名

mHandler.sendMessage(mHandler.obtainMessage(MSG_SET_ALIAS, alias));

}

privatefinalTagAliasCallback mAliasCallback =newTagAliasCallback() {

@Override

publicvoidgotResult(intcode, String alias, Set<String> tags) {

String logs ;

switch(code) {

case:

logs ="Set tag and alias success";

Log.i(TAG, logs);

break;

case:

logs ="Failed to set alias and tags due to timeout. Try again after 60s.";

Log.i(TAG, logs);

mHandler.sendMessageDelayed(mHandler.obtainMessage(MSG_SET_ALIAS, alias),*);

break;

default:

logs ="Failed with errorCode = "+ code;

Log.e(TAG, logs);

}

ExampleUtil.showToast(logs, getApplicationContext());

}

};

privatestaticfinalintMSG_SET_ALIAS =;

privatefinalHandler mHandler =newHandler() {

@Override

publicvoidhandleMessage(android.os.Message msg) {

super.handleMessage(msg);

switch(msg.what) {

caseMSG_SET_ALIAS:

Log.d(TAG,"Set alias in handler.");

// 调用 JPush 接口来设置别名。

JPushInterface.setAliasAndTags(getApplicationContext(), (String) msg.obj,null, mAliasCallback);

break;

default:

Log.i(TAG,"Unhandled msg - "+ msg.what);

}

}

};

自定义通知栏的样式

自定义样式放在init()之后.

                CustomPushNotificationBuilder builder=new CustomPushNotificationBuilder(MainActivity.this, R.layout.my_push, R.id.iv_push, R.id.tv_title, R.id.tv_content);

                builder.statusBarDrawable=R.drawable.ic_category_2;//最顶层状态栏小图标

                builder.layoutIconDrawable=R.drawable.ic_category_2;  //下拉状态时显示的通知图标.

                JPushInterface.setPushNotificationBuilder(2, builder);

JPushInterface.setDefaultPushNotificationBuilder(builder); //设置该对话框为默认

.自定义消息:

所接收的消息不再局限于Notification,而是可以直接取出消息中的内容,从而用自己的方式显示给用户.

此时需要自定义一个MyReceiver继承自BroadcastReceiver.

public class MyReceiver extends BroadcastReceiver {

    @Override

    public void onReceive(Context ctx, Intent intent) {

        Bundle bundle =intent.getExtras();   //接受到消息

        Log.e("info", "[MyReceiver] onReceive - " + intent.getAction() + ", extras: " + printBundle(bundle));

          if (JPushInterface.ACTION_REGISTRATION_ID.equals(intent.getAction())) {

                String regId = bundle.getString(JPushInterface.EXTRA_REGISTRATION_ID);

                Log.d("info", "[MyReceiver] 接收Registration Id : " + regId);

                //send the Registration Id to your server...

            } else if (JPushInterface.ACTION_MESSAGE_RECEIVED.equals(intent.getAction())) {

                Log.d("info", "[MyReceiver] 接收到推送下来的自定义消息: " + bundle.getString(JPushInterface.EXTRA_MESSAGE));

//                processCustomMessage(ctx, bundle);

            } else if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {

                Log.d("info", "[MyReceiver] 接收到推送下来的通知");

                int notifactionId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID);

                Log.d("info", "[MyReceiver] 接收到推送下来的通知的ID: " + notifactionId);

            } else if (JPushInterface.ACTION_NOTIFICATION_OPENED.equals(intent.getAction())) {

                Log.d("info", "[MyReceiver] 用户点击打开了通知");

                JPushInterface.reportNotificationOpened(ctx, bundle.getString(JPushInterface.EXTRA_MSG_ID));

//                //打开自定义的Activity

                Intent i = new Intent(ctx, TwoActivity.class);

                i.putExtras(bundle);

                i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

                ctx.startActivity(i);

            }

    }

    // 打印所有的 intent extra 数据

    private static String printBundle(Bundle bundle) {

        StringBuilder sb = new StringBuilder();

        for (String key : bundle.keySet()) {

            if (key.equals(JPushInterface.EXTRA_NOTIFICATION_ID)) {

                sb.append("/nkey:" + key + ", value:" + bundle.getInt(key));

            } else {

                sb.append("/nkey:" + key + ", value:" + bundle.getString(key));

            }

        }

        return sb.toString();

    }

在类中接收完消息后,还需要在AndroidManifest.xml中添加

<receiver

    android:name="com.lj.pushdemo1.MyReceiver"

    android:enabled="true">

    <intent-filter>

        <action android:name="cn.jpush.android.intent.REGISTRATION" />

        <action android:name="cn.jpush.android.intent.MESSAGE_RECEIVED" />

        <action android:name="cn.jpush.android.intent.NOTIFICATION_RECEIVED" />

        <action android:name="cn.jpush.android.intent.NOTIFICATION_OPENED" />

        <category android:name="com.lj.pushdemo1" />

    </intent-filter>

</receiver>

获取 RegistrationID API

集成了JPush SDK的应用程序第一次注册到JPush服务器时,服务器会返回一个唯一的该设备的标识:RegistertionID.

String id=JPushInterface.getRegistrationID(MainActivity.this);

调用网络接口来发送消息

sendno:发送的编号.

app_key: 应用程序的appKey

receiver_type:接受者的类型 ----2.指定tag----3.指定alias----4.广播----5.根据registrationId进行推送.

msg_content:发送的内容,在这里必须要JSON格式.

platform:要发送的平台

verfication_code:将sendno+receiver_typ+receiver_values+API MasterSecret(在应用的详细信息里面)字符串拼接起来后,用md5加密

设置保留最近通知条数 API

JPushInterface.init(context);

JPushInterface.setLatestNotificationNumber(context,);保留最近的3条
