How to receive parameters in app

Please write the app to receive parameter file according as the following description. If the app is installed first time, you need to run it to make the BroadcastReceiver registered. After that, even if it does not run in background, it will self-triggered when you push parameter file and press "settings -> About POS -> POS Configuration -> Update now" on terminal.

Permission

 android.permission.CLOUDPOS_PUSHSERVICE

The application declares the permission in manifest.

Register BroadcastReceiver

Use android BroadcastReceiver to get pushing notice. Here is the demo:

<!-- permission -->
<uses-permission android:name="android.permission.CLOUDPOS_PUSHSERVICE" />

<!-- receiver -->
<receiver
android:name="com.xxx.xxx.receiver.XXBroadcastReceiver">
    <intent-filter>
    	<action android:name="your package name" />
</intent-filter>
</receiver>

public class ParamFileReceiver extends BroadcastReceiver {
		
		private static final String MSG_TYPE_PARAM = "param:";
		@Override
		public void onReceive(Context context, Intent intent) {
			String notification = intent.getStringExtra("notification");
			if (notification != null
	&&MSG_TYPE_PARAM.equals(notification.subSequence(0,
MSG_TYPE_PARAM.length()))) {
				// remove unnecessary characters
				String fileName = notification
                                      .substring(MSG_TYPE_PARAM.length());
			}
		}
	}
}

Please notice that the pushed information has a type field, it is used to distinguish the third-party information pushed.

Get downloaded file name

Use BroadcastReceiver to get parameter file's name. And use ContentResolver to get file stream. Here is the demo:

String URI_PARAM_FILE = "content://com.wizarpos.wizarviewagent.paramfilesprovider/file/";

Uri uri = Uri.parse(ParamFileProvider.URI_PARAM_FILE + fileName);
ContentResolver resolver = context.getContentResolver();
Reader reader = null;
try {
	reader = new InputStreamReader(resolver.openInputStream(uri));
} catch (FileNotFoundException e) {
e.printStackTrace();
}

The callback of the result of distribute parameters

Send the distributed result to WizarView, WizarView will decide weather the parameter file is completed. If completed, stop the push. Otherwise, it will push all the time.Here is the demo:

public static final String KEY_READED = "readed";
public static final String KEY_ERRLOG = "errlog";

String URI_PARAM_FILE = "content://com.wizarpos.wizarviewagent.paramfilesprovider/file/";

Uri uri = Uri.parse(ParamFileProvider.URI_PARAM_FILE + fileName);
ContentResolver resolver = context.getContentResolver();
ContentValues vaules = new ContentValues();

vaules.put("readed", true);
vaules.put("readed", false);
vaules.put("errlog", "Error in parameter information.Can not apply");

// give the result to the server
Uri resultUri = resolver.insert(uri, vaules);
if(resultUri == null){
	Log.e(APP_TAG, "param happen error , you need check log for modify this question!");
}
