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
