android配置文件渠道名称怎么写

获取友盟渠道名

public static String getChannelName(Activity ctx) {
if (ctx == null) {
return null;
}
String channelName = null;
try {
PackageManager packageManager = ctx.getPackageManager();
if (packageManager != null) {
//注意此处为ApplicationInfo 而不是 ActivityInfo,因为友盟设置的meta-data是在application标签中，而不是某activity标签中，所以用ApplicationInfo
ApplicationInfo applicationInfo = packageManager.getApplicationInfo(ctx.getPackageName(), PackageManager.GET_META_DATA);
if (applicationInfo != null) {
if (applicationInfo.metaData != null) {
<span style="white-space:pre"> </span>//key换成说需要的key
channelName = applicationInfo.metaData.getString(key);
}
}

}
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return channelName;
}

提取为通用方法：


public static String getAppMetaData(Context ctx, String key) {
if (ctx == null || TextUtils.isEmpty(key)) {
return null;
}
String resultData = null;
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) {
resultData = applicationInfo.metaData.getString(key);
}
}

}
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}

return resultData;
}
