直接上代码,不用解释

<span style="font-size:18px;">ApplicationInfo appInfo = null;
		try {
			appInfo = getPackageManager().getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA);
		} catch (NameNotFoundException e) {
			e.printStackTrace();
		}
		if (appInfo.metaData != null) {

			String appid = appInfo.metaData.getString("PUSH_APPID");
			String appsecret = appInfo.metaData.getString("PUSH_APPSECRET");
			String appkey = (appInfo.metaData.get("PUSH_APPKEY") != null) ? appInfo.metaData.get("PUSH_APPKEY").toString() : null;
			Log.e(TAG,"appid="+appid);
			Log.e(TAG,"appsecret="+appsecret);
			Log.e(TAG,"appkey="+appkey);
		}</span>
