Android Development Backend Cloud Bmob usage

<span id="Label3"></p><p><p>Since the development of the application needs to build servers and databases, so understand the online back-end cloud services, The initial understanding of the choice of domestic bmob, the following is a brief introduction of its use:</p></p>1. Register BMOB Account<p><p>Enter www.bmob.cn in the URL field or in the Baidu input Bmob to search, open Bmob official website, Click on the top right corner of the "registration", in the jump page fill in your name, email, set the password, confirm to your mailbox activation Bmob account, You can use Bmob easy to develop the Application.</p></p><p><p></p></p>2. Site background Creation app<p><p>After entering the Bmob backstage, click "create app" in the upper left corner of the background screen, enter the name of your app in the pop-up box, then confirm that you have an app waiting to be Developed.</p></p><p><p></p></p>3. Get the app key and download the SDK<p><p>Select the app you want to develop and go to the app</p></p><p><p></p></p><p><p>On the jump page, go to settings/app key, click Copy to get Application ID</p></p><p><p></p></p><p><p></p></p><p><p></p></p>4. Installing BMOBSDK<p><p>first, Create the "libs" directory under your project root directory and place the downloaded BMOBSDK file in the Directory.</p></p><p><p>second, Add the appropriate permissions in your Application's <code>AndroidManifest.xml</code> files:</p></p><pre class="brush:php;gutter:true;"><uses-permission android:name= "android.permission.INTERNET"/><uses-permission android:name= " Android.permission.ACCESS_WIFI_STATE "/><uses-permission android:name=" android.permission.ACCESS_NETWORK_ State "/><uses-permission android:name=" Android.permission.READ_PHONE_STATE "/><uses-permission Android:name= "android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name= " Android.permission.READ_LOGS "/><?xml version=" 1.0 "encoding=" utf-8 "?> <manifest xmlns:android="/http/ Schemas.android.com/apk/res/android "package=" cn.bmob.example "android:versioncode=" 1 "android:versio Nname= "1.0" > <uses-sdk android:minsdkversion= "8" android:targetsdkversion= "+"/> <uses-permission Andro Id:name= "android.permission.INTERNET"/> <uses-permission android:name= "android.permission.ACCESS_NETWORK_ State "/> <uses-permission android:name=" Android.permission.ACCESS_WIFI_STATE "/> <uses-permission Android:name= "android.permission.READ_PHONE_STATE"/> <uses-permission android:name= " Android.permission.RECEIVE_BOOT_COMPLETED "/> <uses-permission android:name=" android.permission.WRITE_ External_storage "/> <uses-permission android:name=" Android.permission.READ_LOGS "/> <application A ndroid:allowbackup= "true" android:icon= "@drawable/ic_launcher" android:label= "@string/app_name" Andro Id:theme= "@style/apptheme" > <activity android:name= "cn.bmob.example.MainActivity" andro id:screenorientation= "portrait" android:label= "@string/app_name" > <action android:name= "an Droid.intent.action.MAIN "/> <category android:name=" Android.intent.category.LAUNCHER "/> &lt ; Activity android:name= ".
