1.在Bmob官方网站的下载界面中，选择下载AndroidSDK，将下载的zip压缩包进行解压，得到bmobPush_版本号.jar，然后将它放在项目根目录下的"libs"目录中。

2.在应用程序AndroidManifest.xml文件中添加相应的权限：

    <permission        android:name="cn.bmob.permission.push"        android:protectionLevel="normal" >    </permission>    <uses-permission android:name="cn.bmob.permission.push" /> <!-- 添加自定义的权限 -->    <uses-permission android:name="android.permission.READ_LOGS" />    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.READ_PHONE_STATE" />    <uses-permission android:name="android.permission.WAKE_LOCK" />    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <uses-permission android:name="android.permission.VIBRATE" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <uses-permission android:name="android.permission.RECEIVE_USER_PRESENT" />

3.在应用程序AndroidManifest.xml文件中注册BmobPush SDK运行所需的推送服务和消息接收器：

        <service            android:name="cn.bmob.push.lib.service.PushService"            android:exported="true"            android:label="PushService"            android:permission="cn.bmob.permission.push"            android:process="cn.bmob.push" >            <intent-filter>                <action android:name="cn.bmob.push.lib.service.PushService" />            </intent-filter>        </service>        <receiver android:name="cn.bmob.push.PushReceiver" >            <intent-filter android:priority="2147483647" > <!-- 优先级加最高 -->                <!-- 系统启动完成后会调用 -->                <action android:name="android.intent.action.BOOT_COMPLETED" />                <!-- 解锁完成后会调用 -->                <action android:name="android.intent.action.USER_PRESENT" />                <!-- 监听网络连通性 -->                <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />            </intent-filter>        </receiver>        <receiver android:name=".PushReceiver" >            <intent-filter>                <action android:name="cn.bmob.push.action.MESSAGE" />            </intent-filter>        </receiver>

4.在activity_main.xml文件中添加控件。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".MainActivity" >    <Button        android:id="@+id/push"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignBottom="@+id/query_btn"        android:layout_alignRight="@+id/button1"        android:text="Push"        android:onClick="Push" /></RelativeLayout>

5.修改ActivitMain.java文件。

public class MainActivity extends Activity {private EditText mName;private EditText mFeedback;private EditText mQuery;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);// BmobPush的SDK初始化，并启动BmobInstallation.getCurrentInstallation(this).save();BmobPush.startWork(this, "0f83bf800fee187180e4191c4daecd68");}public void Push(View view) {BmobPushManager push = new BmobPushManager(MainActivity.this);push.pushMessageAll("Test");}}

6.在应用程序中创建一个消息接收器。

Push消息通过action=cn.bmob.push.action.MESSAGE的Intent把数据发送给客户端PushReceiver,消息格式由应用自己决定，PushService只负责把服务器下发的消息以字符串格式透传给客户端。PushReceiver代码示例如下：

public class PushReceiver extends BroadcastReceiver {String message = "";@Overridepublic void onReceive(Context context, Intent intent) {if (intent.getAction().equals(PushConstants.ACTION_MESSAGE)) {String msg = intent.getStringExtra(PushConstants.EXTRA_PUSH_MESSAGE_STRING);Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();JSONTokener jsonTokener = new JSONTokener(msg);try {JSONObject object = (JSONObject) jsonTokener.nextValue();message = object.getString("alert");//获取具体的消息内容} catch (JSONException e) {e.printStackTrace();}//把Notification显示在通知中NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);Notification notification = new Notification(R.drawable.ic_launcher, "Notification comes",System.currentTimeMillis());notification.setLatestEventInfo(context, "Bmob Test", message, null);manager.notify(R.drawable.ic_launcher, notification);}}}
