Bmob 萌新也能简易上手之一注册登录- *2020版（有demo）

前言：一切以Bmob官方开发文档为准： http://doc.bmob.cn/data/android/develop_doc/ ，新手快速入门： http://doc.bmob.cn/data/android/ 。查看Bmob后台数据是个好习惯
作为只会app客户端，不懂服务端的人，Bmob简直就是救命稻草！用它来存放爬取的数据，朋友圈数据，图片语音视频,还有app版本更新…易如反掌。经常有同学问如何上传头像、文件、图片bla bla，重要的事说三遍：绑定独立域名，绑它，绑它！具体怎么绑问度娘。当然Bmob也提供此类服务，收费,至于价格，还好啦…demo下载：

demo基于androidx，AS4.0导入demo无压力。先让app跑起来，再细看代码。固执使用V4,V7包的同学，自行导包，代码基本一致。官网下个AS 4.0不香么，无需翻墙，速度很快： https://developer.android.google.cn/studio 。安装参考： https://blog.csdn.net/qq_41976613/article/details/91432304
本文除Bmob注册登录，还有沉浸式状态栏、权限申请的方法

特别提醒：使用androidx的同学 ,查看下 gradle.properties文件中是否包含以下两行，若无则加上：

android.useAndroidX=true
android.enableJetifier=true

一、Bmob SDK 导入

1）工程目录下的 build.gradle 文件中添加：

maven {url 'https://dl.bintray.com/chaozhouzhang/maven' }

添加后的样子：


// Top-level build file where you can add configuration options common to all sub-projects/modules.buildscript {repositories {google()jcenter()}dependencies {classpath 'com.android.tools.build:gradle:3.5.3'// NOTE: Do not place your application dependencies here; they belong// in the individual module build.gradle files}
}allprojects {repositories {google()jcenter()maven {url 'https://dl.bintray.com/chaozhouzhang/maven' }}
}task clean(type: Delete) {delete rootProject.buildDir
}

2) app下 build.gradle 文件中添加：

1）useLibrary 'org.apache.http.legacy'
2）compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1_8}3）implementation 'cn.bmob.android:bmob-sdk:3.7.8'implementation 'io.reactivex.rxjava2:rxjava:2.2.6'implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'implementation 'com.squareup.okhttp3:okhttp:3.14.1'implementation 'com.squareup.okio:okio:2.2.2'implementation 'com.google.code.gson:gson:2.8.5'

添加后的build.gradle文件：

apply plugin: 'com.android.application'android {useLibrary 'org.apache.http.legacy'compileSdkVersion 29buildToolsVersion "29.0.2"defaultConfig {applicationId "com.example.asus.bmobtest"minSdkVersion 21targetSdkVersion 29versionCode 1versionName "1.0"testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'}}compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1_8}
}dependencies {implementation fileTree(dir: 'libs', include: ['*.jar'])implementation 'androidx.appcompat:appcompat:1.1.0'implementation 'androidx.constraintlayout:constraintlayout:1.1.3'testImplementation 'junit:junit:4.12'androidTestImplementation 'androidx.test:runner:1.2.0'androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'implementation 'cn.bmob.android:bmob-sdk:3.7.8'implementation 'io.reactivex.rxjava2:rxjava:2.2.6'implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'implementation 'com.squareup.okhttp3:okhttp:3.14.1'implementation 'com.squareup.okio:okio:2.2.2'implementation 'com.google.code.gson:gson:2.8.5'
}

前面两步是如何导入Bmob，不要忘记同步一下

二、清单文件配置

配置 Bmob Provider

<!--Bmob--><providerandroid:name="cn.bmob.v3.util.BmobContentProvider"android:authorities="自己的包名.BmobContentProvider" />

***强烈建议在清单文件里加上相应权限，否则注册时会出现9015错误
errorCode:9015,errorMsg:java.net.Inet6AddressImpl.lookupHostByName(Inet6AddressImpl.java:150)
FileProvider请改成自己报名
完整清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"package="com.example.asus.bmobtest"><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android: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.WAKE_LOCK" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/><uses-permission android:name="android.permission.CAMERA"/><uses-permission android:name="android.permission.READ_CONTACTS"/><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.RECORD_AUDIO"/><uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/><uses-permission android:name="android.permission.VIBRATE"/><uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/><uses-permission android:name="android.permission.CALL_PHONE"/><applicationandroid:name=".base.BaseApp"android:allowBackup="true"android:icon="@mipmap/ic_launcher"android:networkSecurityConfig="@xml/network_security_config"android:requestLegacyExternalStorage="true"android:label="@string/app_name"android:roundIcon="@mipmap/ic_launcher_round"android:supportsRtl="true"android:theme="@style/AppTheme"android:usesCleartextTraffic="true"tools:ignore="GoogleAppIndexingWarning"><activity android:name=".activity.LoginActivity"  ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity> <!-- Bmob --><providerandroid:name="cn.bmob.v3.util.BmobContentProvider"android:authorities="com.example.asus.bmobtest.BmobContentProvider" /><providerandroid:name="androidx.core.content.FileProvider"android:authorities="com.example.asus.bmobtest.fileprovider"android:exported="false"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/filepaths" /></provider><activity android:name=".TestActivity"   /><activity android:name=".activity.RegisterActivity" /></application></manifest>

三、数据类

1）用户类 MyUser，注意要继承BmobUser

public class MyUser extends BmobUser {private String tokenNickName;public String getTokenNickName() {return tokenNickName;}public void setTokenNickName(String tokenNickName) {this.tokenNickName = tokenNickName;}
}

2）Bmob单例管理类：BmobManager

public class BmobManager {private static final String BMOB_SDK_ID = "自己Bmob账号";private volatile static BmobManager mInstance = null;private BmobManager() {}public static BmobManager getInstance() {if (mInstance == null) {synchronized (BmobManager.class) {if (mInstance == null) {mInstance = new BmobManager();}}}return mInstance;}//初始化Bmobpublic void initBmob(Context mContext) {Bmob.initialize(mContext, BMOB_SDK_ID);}// 手机登录成功后获取本地对象public MyUser getUser() {return BmobUser.getCurrentUser(MyUser.class);}// 是否登录public boolean isLogin() {return BmobUser.isLogin();}}

3）自定义Application类

对Bmob进行初始化，并在清单文件 AndroidManafest.xml 标签下进行指定，保险起见务必加上该类完整包名！

public class BaseApp extends Application {private static Context sContext;private static int mainThreadId;private static Handler handler;@Overridepublic void onCreate() {super.onCreate();sContext = getApplicationContext();mainThreadId = android.os.Process.myTid();handler = new Handler();//只在主进程中初始化if (getApplicationInfo().packageName.equals(getCurProcessName(getApplicationContext()))) {//初始化bmobBmobManager.getInstance().initBmob(this);SpUtils.getInstance().initSp(sContext);//对SharedPreference进行初始化}}@Overridepublic void onTrimMemory(int level) {super.onTrimMemory(level);}// 获取当前进程名public static String getCurProcessName(Context context) {int pid = android.os.Process.myPid();ActivityManager activityManager = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);for (ActivityManager.RunningAppProcessInfo appProcess :activityManager.getRunningAppProcesses()) {if (appProcess.pid == pid) {return appProcess.processName;}}return null;}public static Handler getHandler() {return handler;}public static Context getContext() {return sContext;}public static int getMainThreadId() {return mainThreadId;}
}

    android:name=".base.BaseApp"

四、活动基类BaseActivity

权限申请，其他项目也能用

public class BaseActivity extends AppCompatActivity {//申请运行时权限的Codeprivate static final int PERMISSION_REQUEST_CODE = 1000;//申请窗口权限的Codepublic static final int PERMISSION_WINDOW_REQUEST_CODE = 1001;//申明所需权限private String[] mStrPermission = {Manifest.permission.READ_PHONE_STATE,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CAMERA,Manifest.permission.READ_CONTACTS,Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.RECORD_AUDIO,Manifest.permission.CALL_PHONE,Manifest.permission.ACCESS_FINE_LOCATION};//保存没有同意的权限private List<String> mPerList = new ArrayList<>();//保存没有同意的失败权限private List<String> mPerNoList = new ArrayList<>();private OnPermissionsResult permissionsResult;/*** 一个方法请求权限** @param permissionsResult*/protected void request(OnPermissionsResult permissionsResult) {Log.i("register","base activity request 请求权限:" );if (!checkPermissionsAll()) {requestPermissionAll(permissionsResult);}}/*** 判断单个权限** @param permissions* @return*/protected boolean checkPermissions(String permissions) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {int check = checkSelfPermission(permissions);return check == PackageManager.PERMISSION_GRANTED;}return false;}/*** 判断是否需要申请权限** @return*/protected boolean checkPermissionsAll() {mPerList.clear();for (int i = 0; i < mStrPermission.length; i++) {boolean check = checkPermissions(mStrPermission[i]);//如果不同意则请求if (!check) {mPerList.add(mStrPermission[i]);}}return mPerList.size() > 0 ? false : true;}/*** 请求权限** @param mPermissions*/protected void requestPermission(String[] mPermissions) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {requestPermissions(mPermissions, PERMISSION_REQUEST_CODE);}}/*** 申请所有权限** @param permissionsResult*/protected void requestPermissionAll(OnPermissionsResult permissionsResult) {this.permissionsResult = permissionsResult;requestPermission((String[]) mPerList.toArray(new String[mPerList.size()]));}@Overridepublic void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {mPerNoList.clear();if (requestCode == PERMISSION_REQUEST_CODE) {if (grantResults.length > 0) {for (int i = 0; i < grantResults.length; i++) {if (grantResults[i] == PackageManager.PERMISSION_DENIED) {//你有失败的权限mPerNoList.add(permissions[i]);}}if (permissionsResult != null) {if (mPerNoList.size() == 0) {permissionsResult.OnSuccess();} else {permissionsResult.OnFail(mPerNoList);}}}}super.onRequestPermissionsResult(requestCode, permissions, grantResults);}protected interface OnPermissionsResult {void OnSuccess();void OnFail(List<String> noPermissions);}/*** 判断窗口权限** @return*/protected boolean checkWindowPermissions() {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {return Settings.canDrawOverlays(this);}return true;}/*** 请求窗口权限*/protected void requestWindowPermissions() {Toast.makeText(this, "申请窗口权限，暂时没做UI交互", Toast.LENGTH_SHORT).show();Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName()));startActivityForResult(intent, PERMISSION_WINDOW_REQUEST_CODE);}   }

五、注册类RegisterActivity

这里为了方便，使用账号密码登录，也可用短信或者第三方登录。短信登录每天有免费条数限制，具体查看官方文档。下面的注册方法，请从界面的EditText读取相关数据再调用。
参数：
myAccount 账号，方便起见，请填入电话号码
password 密码
nickName 你的网络称呼
关键注册代码：

//账号密码注册，private void signUp(final String myAccount, final String password,String nickName) {MyUser user = new MyUser();user.setUsername(myAccount);user.setPassword(password);user.setTokenNickName(nickName);user.signUp(new SaveListener<MyUser>() {@Overridepublic void done(MyUser user, BmobException e) {if (e == null) {Loggerr.i("注册成功");//去登录loginByAccount(myAccount, password);} else {Loggerr.i("注册失败：" + e.toString());}}});}

五、登录类LoginActivity

若为单独登录界面，请从界面的EditText读取相关数据再调用。参数注册。关键代码：

/*** 账号密码登录*/private void loginByAccount(final String username, String password) {//此处替换为你的用户名密码BmobUser.loginByAccount(username, password, new LogInListener<MyUser>() {@Overridepublic void done(MyUser user, BmobException e) {if (e == null) {Loggerr.i("登录成功");startActivity(new Intent(LoginActivity.this, TestActivity.class));} else {Loggerr.i("登录失败：" + e.toString());Toast.makeText(LoginActivity.this, "登录失败："+ e.toString(), Toast.LENGTH_SHORT).show();//不能回复自己评论弹出删除框}}});}

六、运行代码

登录成功后，去Bmob后台查看_User表，确定注册成功
登录Bmob，查看后台数据

Bmob后台用户数据：

登录成功后，成功跳转主页面：
