LeanCloud在android studio的SDK安装和连接

之前看官方文档看到头晕，网上我看都是有jar包的，我就有点迷终于摸索出来了一点方法在Android studio中去安装SDK，连接leancloud

官网下载好SDK

可以根据需要下载，可用Git，SDK下载网址：

点击链接下载: SDK下载.

复制相应包

看产品文档需要哪个包，就下载哪个。在这里我需要存取数据，所以用了leancloud-push-lite，把这一整个文件夹放到项目的目录下

放置目录如图：

修改整个项目的gradle文件（可适当参照对比）

buildscript {
    
    repositories {
        google()
        jcenter()
        maven {
            url "https://oss.sonatype.org/content/groups/public/"//仓库地址
        }

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://oss.sonatype.org/content/groups/public/"//仓库地址
        }


    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

在app的build.gradle依赖加上

    implementation 'cn.leancloud:storage-android:6.5.6'
    implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'

把

 implementation fileTree(dir: 'libs', include: ['*.jar'])

再修改为

   // implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation ('cn.leancloud:realtime-android:6.5.3') {
        exclude group: 'cn.leancloud', module: 'realtime-core'}

加上

    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    lintOptions {
        abortOnError false
    }

所有修改之后如下，可对比参照：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"

    defaultConfig {
        applicationId "com.example.huanwu"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }


    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    lintOptions {
        abortOnError false
    }


}

dependencies {
   // implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation ('cn.leancloud:realtime-android:6.5.3') {
        exclude group: 'cn.leancloud', module: 'realtime-core'
    }

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'


    implementation 'androidx.recyclerview:recyclerview:1.2.0-alpha03'

    implementation 'cn.leancloud:storage-android:6.5.6'
    implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'

}

在app的AndroidManifest.xml文件上

加上

  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

 android:name=".MainActivity"

 <receiver android:name="cn.leancloud.push.AVBroadcastReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
                <action android:name="android.intent.action.USER_PRESENT"/>
                <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
            </intent-filter>
        </receiver>

修改之后的文件参考如下

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.test">

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

    <application
        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/AppTheme"
        android:name=".MainActivity">
        >

        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <receiver android:name="cn.leancloud.push.AVBroadcastReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
                <action android:name="android.intent.action.USER_PRESENT"/>
                <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
            </intent-filter>
        </receiver>

    </application>

</manifest>

测试自己的活动

package com.example.test;

import androidx.appcompat.app.AppCompatActivity;
import android.app.Application;
import android.os.Bundle;
import cn.leancloud.AVOSCloud;
import cn.leancloud.AVObject;

public class MainActivity  extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        // 提供 this、App ID、App Key、Server Host 作为参数
        // 注意这里千万不要调用 cn.leancloud.core.AVOSCloud 的 initialize 方法，否则会出现 NetworkOnMainThread 等错误。
        AVOSCloud.initialize(this, "XC2Rr7WVhYA68PaFTu2voQQf-gzGzoHsz", "UF3Ivhw9uLXPDUDJ4m2MBTQh", "https://please-replace-with-your-customized.domain.com");//放自己的域名

        AVObject testObject = new AVObject("TestObject");
        testObject.put("words", "Hello world!");
        testObject.saveInBackground().blockingSubscribe();
    }
}

如果编译有问题，可以尝试在app的build.gradle加上

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

加上之后参考如下

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"

    defaultConfig {
        applicationId "com.example.huanwu"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }


    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    lintOptions {
        abortOnError false
    }


}

测试成功
