Gradle动态配置 （1）

什么是BuildTypes、Flavors、BuildVariants

BuildTypes：构建类型，AndroidStudio的Gradle组件默认提供给了“debug”“release”两个默认配置，此处用于配置是否需要混淆、是否可调试等

Flavors：产品渠道，默认不提供任何默认配置，在实际发布中，根据不同渠道，我们可能需要用不同的包名，服务器地址等

BuildVariants：每个buildtype和flavor组成一个buildvariant

productFlavors {
	shichang360 {
	//设置manifest变量
		manifestPlaceholders = [INSTALL_CHANNEL_VALUE: "360"]
	}
	wandoujia {
		manifestPlaceholders = [INSTALL_CHANNEL_VALUE: "wandoujia"]
	}
	yingyongbao {
		manifestPlaceholders = [INSTALL_CHANNEL_VALUE: "yingyongbao"]
	}
}

也就是说，可以根据三个市场版本，与三种不同的buildType 形成九个组合，既9个BuildVariants

buildTypes {

		buildConfigField("String", "APP_DOMAIN_URL", "\"http://172.25.50.50:8105\"")
		buildConfigField("String", "APP_DOMAIN_NO_SE_URL", "\"http://172.25.50.51:8008\"")
		buildConfigField("String", "SAFEGUARD_RELEASE_KEY", "\"DixGK928Zqyge0BR2SC23ZzYgkm4SAcU\"")
		buildConfigField("String", "APP_FEEDBACK_URL", "\"http://172.24.9.15:8101/app/help\"")
		// 移除无用的resource文件 动态资源绑定会被删除，暂时关闭
		shrinkResources false
		//zipAlign 优化 http://www.jizhuomi.com/android/environment/203.html
		zipAlignEnabled true
		minifyEnabled true
		proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro', 'proguard-robile-rules.pro'
		signingConfig signingConfigs.config
	}
	//debug运行版本
	debug {
		buildConfigField("String", "APP_DOMAIN_URL", "\"http://172.25.50.50:8105\"")
		buildConfigField("String", "APP_DOMAIN_NO_SE_URL", "\"http://172.25.50.51:8008\"")
		buildConfigField("String", "SAFEGUARD_RELEASE_KEY", "\"gQhUN4JRQAinOuM4+c/qLDFGE2cg1MIsdyjao0j8y60=\"")
		buildConfigField("String", "APP_FEEDBACK_URL", "\"http://172.24.9.15:8101/app/help\"")
		zipAlignEnabled false
		minifyEnabled false
		signingConfig signingConfigs.config
		manifestPlaceholders = [INSTALL_CHANNEL_VALUE: "test"]
	}
}

默认debug运行时设置渠道为“test”

		android:value="${INSTALL_CHANNEL_VALUE}"/>

		//获取渠道信息
		ApplicationInfo applicationInfo = null;
		try {
			applicationInfo = getPackageManager().getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA);
		} catch (PackageManager.NameNotFoundException e) {
			e.printStackTrace();
		}
		if (applicationInfo != null) {
			String value = applicationInfo.metaData.getString("INSTALL_CHANNEL_VALUE");
			RunningContext.setInstallValue(value);
//			System.out.println("INSTALL_CHANNEL_VALUE" + value);
//			JDRToast.makeText(this, "INSTALL_CHANNEL_VALUE	" + value).show();
		}

参照钱包之前做法，渠道号用于接口请求公共参数上，至此，渠道号设置完毕。
