Environment requirements (optional)

SDK Integration

1. Decompress the SDK package.

   Download and decompress the software package to obtain the files shown in the figure below.

   Figure 1 File directory
   

2. Create a project.
   • Open Android Studio, choose File > New > New Project, choose Phone and Tablet > Empty Activity, and click Next.
   Figure 2 Creating a project
   
   • Enter project information and click Finish. (Note that the minimum Android API version is 23.)
   Figure 3 Setting project information
   

3. Integrate the SDK.
   • In Android Studio, switch the project directory to Project.
     Figure 4 Switching to Project

     

   • Copy the .aar packages in the libs directory to your project directory.
     Figure 5 Adding the .aar packages

     

4. Add dependencies.
   • Add a third-party dependency.

   The SDK depends on some open-source libraries. You must add dependencies on these libraries in Gradle as follows:

   Create the config.gradle file in the root directory of the project. (If you have created a unified configuration file, refer to the config.gradle file in the demo to configure the version.)

   Figure 6 Opening the config.gradle file
   
   • Add the following information to the first line of the build.gradle file:

     apply from:"config.gradle"

     The third-party dependency statement and version number used in config.gradle are as follows:

                 "rxandroid"              : 'io.reactivex.rxjava3:rxandroid:3.0.2',
                 "appcompat-v7"           : 'androidx.appcompat:appcompat:1.3.0',
                 "vectordrawable"         : 'androidx.vectordrawable:vectordrawable:1.2.0-alpha02',
                 "rxjava"                 : 'io.reactivex.rxjava3:rxjava:3.0.13',
                 "recyclerview"           : 'androidx.recyclerview:recyclerview:1.2.1',
                 "aspectjrt"              : 'org.aspectj:aspectjrt:1.9.6', 
                 "okhttp"                 : 'com.squareup.okhttp3:okhttp:4.9.1',
                 "gson"                   : 'com.google.code.gson:gson:2.8.9',
                 "design"                 : 'com.google.android.material:material:1.3.0',
                 "lifecycle-process"      : 'androidx.lifecycle:lifecycle-process:2.4.1',
                 "eventbus"               : 'org.greenrobot:eventbus:3.3.1',
                 "constraint-layout"      : 'androidx.constraintlayout:constraintlayout:2.0.4',
                 "glide"                  : 'com.github.bumptech.glide:glide:4.13.0',
                 "swiperefreshlayout"     : 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0',
                 "hms:scan-kit"           : 'com.huawei.hms:scan:2.1.0.300',

   Figure 7 Setting the build.gradle file
   
   • Add the open-source package dependencies and meeting SDK dependencies to app/build.gradle.
     

     The original Android Support Library is no longer maintained or evolved by Google. Therefore, Android 28 will be upgraded to AndroidX.

     Since the 70.8.5 version released in August, Huawei Cloud Meeting will no longer be developed based on the Support Library. Instead, AndroidX will be used for iteration.

     If you are still using the original Android Support Library dependency:

     • It is recommended that you change it to the AndroidX dependency. Otherwise, you may fail to connect to the AndroidX SDK version in subsequent development. For details, see Getting Started.
     • If you cannot upgrade to Android X as soon as possible, we will provide the original SDK developed based on the Support Library and maintain the SDK for six months. During the maintenance period, you can still integrate our SDK of 70.7.5 and earlier versions for development. Issues found in these versions will be fixed and updated. However, new functions in later iterations will be implemented only on the SDK of AndroidX.

     If you have any questions, dial 4000-955-988 or 950808 and press 1 and then 2.

     1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

     // Some third-party frameworks used by the SDK api rootProject.ext.dependencies["appcompat-v7"] api rootProject.ext.dependencies["recyclerview"] api rootProject.ext.dependencies["design"] api rootProject.ext.dependencies["aspectjrt"] api rootProject.ext.dependencies["rxandroid"] api rootProject.ext.dependencies["constraint-layout"] api rootProject.ext.dependencies["glide"] implementation rootProject.ext.dependencies["rxjava"] implementation rootProject.ext.dependencies["gson"] implementation rootProject.ext.dependencies["eventbus"] implementation rootProject.ext.dependencies["okhttp"] implementation rootProject.ext.dependencies["hms:scan-kit"] implementation rootProject.ext.dependencies["lifecycle-process"] implementation rootProject.ext.dependencies["swiperefreshlayout"]

   • Add the meeting dependencies.

     1 2 3 4 5 6 7 8 9 10

     implementation(name: 'HWMFoundation-release', ext: 'aar') implementation(name: 'HWMMobileCommonUI-release', ext: 'aar') implementation(name: 'HWMMobileConfUI-release', ext: 'aar') implementation(name: 'HWMPermission-release', ext: 'aar') implementation(name: 'HWMNativeSdk-release', ext: 'aar') implementation(name: 'HWMUiSdk-release', ext: 'aar') implementation(name: 'HWMCLink-release', ext: 'aar') if (needConfChat == null || needConfChat.toBoolean()) { implementation(name: 'imsdk-release', ext: 'aar') }

   

   If some modules are injected by themselves or are not opened, you do not need to add dependencies but must delete the corresponding .aar packages.

   These modules are:

   • MobileHybrid module. For details, see Customizing a Screen for Adding Participants to a Meeting.
   • imsdk module. For details, see Enabling or Disabling Chat for a Meeting.
   • Add the following to project/build.gradle allprojects/repositories:

     flatDir { dirs 'libs' }

   If Google cannot be connected, you can add your own Maven repository.

   Figure 8 Adding a Maven repository

   

   • Configure gradle-wrapper.properties by following the instructions provided in Configuring gradle-wrapper.properties.
   Figure 9 gradle-wrapper.properties
   
   • Choose Build > make project and wait until the project compilation is complete.
   

   If libc++_shared.so is integrated into the application layer, no configuration is required. If the dynamic library is used in the .aar package of a third-party library, you only need to add the following configuration in the build.gradle file:

   packagingOptions {

   merge lib/armeabi-v7a/libc++shared.so

   }

5. Configure the obfuscation script.
   • Add the following information to the build.gradle file to configure the obfuscation script:

   buildTypes {
           release {
               minifyEnabled true
               proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
           }
   }

   • Add the following information to the proguard-rules.pro file:

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318

6. Add permissions.
   Add permissions required in the AndroidManifest.xml file.

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

   <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.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.DISABLE_KEYGUARD" /> <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" /> <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" /> <uses-permission android:name="com.huawei.android.launcher.permission.CHANGE_BADGE" /> <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.VIBRATE" /> <!--Enable the foreground server to keep alive during the meeting.--> <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

7. Add the screen sharing service.
   To use the screen sharing function, add the following service statement to the AndroidManifest.xml file:

   1 2 3 4

   <!-- Add the following configuration to the SDK. If the value of compileSdkVersion is greater than or equal to 29, add android:foregroundServiceType="mediaProjection". Otherwise, delete android:foregroundServiceType="mediaProjection".--> <service android:name="com.huawei.hwmconf.sdk.ScreenRecorderService" 4ce9861d-fad1-42b6-807c-fbf8a0c2320e2412108500276004ce9861d-fad1-42b6-807c-fbf8a0c2320e241210850027600android:exported="false" android:enabled="true"/>

8. Initialize the SDK.
   • The initialization must be placed in onCreate of the application, and it must be called as early as possible so that the SDK can obtain the current activity and jump to a specified page by listening to the activity lifecycle.

     1 2 3 4 5

     OpenSDKConfig sdkConfig = new OpenSDKConfig(this) .setAppId("fdb8e4699586458bbd10c834872dcc62") // Set a unique app ID. The application name can be entered. This parameter is mandatory when the app ID is used for login. .setServerAddress(DBConfig.Default.getInstance().getServerAddress()) // Set the IP address of the meeting server. .setServerPort(DBConfig.Default.getInstance().getServerPort()); // Set the port of the meeting server. HWMSdk.init(this,sdkConfig);

9. Learn the examples.
   • Login API

     1	HWMSdk.getOpenApi(Application).login(LoginParam, HwmCallback<LoginResult>);

   • API for creating a meeting

     1	HWMSdk.getOpenApi(Application).createConf(CreateConfParam, HwmCancelableCallBack<ConfInfo>);

   • API for joining a meeting

     1	HWMSdk.getOpenApi(Application).joinConf(JoinConfParam, HwmCancelableCallBack<Void>);

   • API for initiating a call
