Android接入阿里云热修复介绍

1.AndroidManinifest.xml中加入权限

 <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_EXTERNAL_STORAGE"/>

2.AndroidManinifest.xml里application中加入以下，在AS中打开在第五步下载的文件
App ID："hotfix.idSecret"
App Secret："emas.appSecret"
RSA密钥："hotfix.rsaSecret"

<meta-data
android:name="com.taobao.android.hotfix.IDSECRET"
android:value="App ID" />
<meta-data
android:name="com.taobao.android.hotfix.APPSECRET"
android:value="App Secret" />
<meta-data
android:name="com.taobao.android.hotfix.RSASECRET"
android:value="RSA密钥" />

3、在app的build.gradle中加入依赖等

plugins { id 'com.android.application'}
//加载文件
apply plugin: 'com.aliyun.ams.emas-services'
android {
    compileSdkVersion 30
    buildToolsVersion '30.0.3'
    defaultConfig {
        applicationId "com.wb.hotfixdemo"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
dependencies {
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'com.google.android.material:material:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
//阿里云依赖
    api 'com.aliyun.ams:alicloud-android-hotfix:3.3.0'
}

4、SophixStubApplication
目前集成已经完毕了，下面就是代码的实现，新建一个类SophixStubApplication继承SophixApplication

public class SophixStubApplication extends SophixApplication {
    private final String TAG = "SophixStubApplication";
    // 此处SophixEntry应指定真正的Application，并且保证RealApplicationStub类名不被混淆。
    @Keep
    @SophixEntry(MyRealApplication.class)
    static class RealApplicationStub {}
    @Override
    public void onCreate() {
        super.onCreate();
        SophixManager.getInstance().queryAndLoadNewPatch();
    }
    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
//         如果需要使用MultiDex，需要在此处调用。
//         MultiDex.install(this);
        initSophix();
    }
    private void initSophix() {
        String appVersion = "0.0.0";
        try {
            appVersion = this.getPackageManager().getPackageInfo(this.getPackageName(), 0).versionName;
        } catch (Exception e) {
        }
        final SophixManager instance = SophixManager.getInstance();
        instance.setContext(this)
                .setAppVersion(appVersion)
                .setSecretMetaData(null, null, null)
                .setEnableDebug(true)
                .setEnableFullLog()
                .setPatchLoadStatusStub(new PatchLoadStatusListener() {
                    @Override
                    public void onLoad(final int mode, final int code, final String info, final int handlePatchVersion) {
                        if (code == PatchStatus.CODE_LOAD_SUCCESS) {
                            Log.i(TAG, "sophix load patch success!");
                        } else if (code == PatchStatus.CODE_LOAD_RELAUNCH) {
                            // 如果需要在后台重启，建议此处用SharePreference保存状态。
                            Log.i(TAG, "sophix preload patch success. restart app to make effect.");
                        }
                    }
                }).initialize();
    }
}

5、MyRealApplication

public class MyRealApplication extends Application {
}

6、AndroidManinifest.xml里加入SophixStubApplication

 <application
        android:name=".SophixStubApplication"//加入此项
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.HotFixDemo">

到这已经完成阿里云热修复的百分之八十，后面就是下载工具实现发布补丁
