AndroidStudio 多渠道打包及获取渠道值以及如何转义纯数字

Build配置

在android{}内加

productFlavors {
        sanxing {
            manifestPlaceholders = [CHANNEL_VALUE: "32d2sss"]
        }
        guanwang {
            manifestPlaceholders = [CHANNEL_VALUE: "\\00000000"]
        }
}

AS 3.0+需在 defaultConfig {}内配置

flavorDimensions "default"//写其他的也行

manifest里的配置

代码中获取渠道号

try {
            PackageManager packageManager = ctx.getPackageManager();
            if (packageManager != null) {
                ApplicationInfo applicationInfo = packageManager.getApplicationInfo(ctx.getPackageName(), PackageManager.GET_META_DATA);
                if (applicationInfo != null) {
                    if (applicationInfo.metaData != null) {
                        String channel = applicationInfo.metaData.get("DEMO_CHANNEL")+"";
                        AppConfig.CHANNEL = channel;
                        LogService.i("Channel","当前的渠道为:"+channel );
                    }
                }
            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
            LogService.e("Channel",e.getMessage()+"");
        }

转义问题

如果你的渠道号是一堆0000001 那么最后获取出来就是1
如果想获取到位000001 那么就需要加转义字符\0000001
