打包升级兼容适配

一. 配置：

implementation 'com.umeng.sdk:common:1.5.1'
implementation 'com.umeng.sdk:analytics:7.5.0'

二.清单文件配置

    <meta-data android:value="5d3572c53fc19544630000d6" android:name="UMENG_APPKEY"/>
    <meta-data android:value="${UMENG_CHANNEL_VALUE}" android:name="UMENG_CHANNEL"/>
# 三. moudle gradle配置
android {
    compileSdkVersion 28
    buildToolsVersion "29.0.0"
    defaultConfig {
        flavorDimensions "default"
        manifestPlaceholders = [qqappid: "100424468"]
        applicationId "com.example.ument"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
        Alpha {//自己打包测试使用
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Alpha]
        }
        Tencent {//投放应用宝市场
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Tencent]
        }
        Baidu {//投放百度市场
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Baidu]
        }
        Qihoo {//投放360市场
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Qihoo]
        }
        Alibaba {//投放阿里巴巴
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Alibaba]
        }
        Vivo {//投放vivo市场
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Vivo]
        }
        Oppo {//投放oppo市场
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Oppo]
        }
        Xiaomi {//投放小米市场
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Xiaomi]
        }
        Huawei {//投放华为应用市场
             manifestPlaceholders = [UMENG_CHANNEL_VALUE: Huawei]
        }

        productFlavors.all { flavor ->
            flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name]
        }
    }

}

国际化

//英文资源
<resources>
    <string name="app_language">language</string>
</resources>

//中文资源
<resources>
    <string name="app_language">语言</string>
</resources>

生成新的Locale对象

public Locale(String language, String country) {
        this(language, country, "");
}

//例如,生成English，不限地区的Locale对象
new Locale("en", ")

更改系统的语言设置

    Resources resources = context.getResources();
    Configuration configuration = resources.getConfiguration();
    configuration.locale = newLocale;
    resources.updateConfiguration(configuration, resources.getDisplayMetrics());//更新配置
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        initLocaleLanguage();
        setContentView(R.layout.activity_main);
    }
}

更改语言配置需要在MainActivity的setContentView()之前设置

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        initLocaleLanguage();
        setContentView(R.layout.activity_main);
    }
}
    private void initLocaleLanguage() {
        Resources resources = context.getResources();
        Configuration configuration = resources.getConfiguration();
        configuration.locale = newLocale;
        resources.updateConfiguration(configuration, resources.getDisplayMetrics());//更新配置

重启MainActivity

//重启MainActivity
Intent intent = new Intent(SettingActivity.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
