simplewallpaperapp-android's Issues

Simple features

Hi there,
I hope you doing well.
I suggest adding these features to the app to make it more interacting and suitable to the user:
1- Randomizing or shuffling the wallpapers at home page to increase the chances of showing the user as much of wallpapers as possible. And to do that I suggest one of these methods:

• Swipe to refresh (when the user swipes the content will be shuffled on Realtime)
• Every time the user opens the app, he would find the content already is shuffled.

For me, I prefer the second one as "swipe to refresh" may cause app crash.

2- Making the wallpapers database online updated (by merging "wallpapers.json" and "categories.json" into one "content.json" or whatever name). To do that, the simplest way imo, is by implementing firebase Realtime database, hence my third suggestion comes:

3- implementing firebase messaging to send users simple messages once new wallpapers or categories would be added.

I think by adding 2 & 3 features, no need to update the app every time new wallpapers would be added to the .json file.

Reward Ad

Can you add Reward Ad? I think the app will be perfect.

package name changing issue

Changing the package name crashes my app. I have changed the package name from AndroidManifest.xml and defaultConfig from build.gradle.

Have i done anything wrong?

Collection Screen causing App Crash if close quickly.

The native ads loads in background of collection screen. If the user close the screen before it loads, App will crash.

Collections Screen is Empty

Hi Man!

Thanks for creating such awesome wallpaper app!

I find the Collections screen is empty. Is it a bug, or must I set something in the code?

Thanks!

Wallpapers not loading in list when device language is Arabic

Hi,
Can you fix this issue please?
I didn't notice at first when I was using the app. The problem is when I scroll down to see other wallpapers the progress bar continues looping for very long time (10 - 15 min. or more) and the wallpapers don't load. This happens only if the device language is other than English (ex; Arabic, Vietnamese, etc...), like in this video.

When I changed the device language to English, it works fine, like in this video

external wallpapers

Is there anything new about making wallpapers inserted into the app without having to insert a new update into the app by placing links within the json?

using a database?

I tried everything I could to use it and contribute here but without success, I ended up giving up.

Native Ad Loading multiple times.

While scrolling, a new ad starts loading and replaces the existing ad. I think this is not ideal to load ad multiple times even if the ad is already loaded.

data Collecting in the application

Hello.. Thank you very much for this wonderful application..
I uploaded the application, and after 15 days, I received this message from Google, and I told support that the application does not collect any information, and they pretended that it collects information .. Please, what is the solution?

Admob GDPR and Disruptive Ads issues

I'd like to bring to your attention two important issues that need immediate attention in the app development:

1. AdMob GDPR and UMP SDK Implementation:
Implement GDPR consent messages for users.

2. Disruptive Ads Issue on Google Console:
The app has been rejected by the Google Console due to disruptive ads.

It's the perfect sauce!

Sounds like a really perfect sauce! From adding a category to adding an image, it's so easy and convenient! If only the json file is changed so that it can be managed on the server rather than assets, it would be a more perfect source!

API level 19

Hi,
I wanted to increase the number of users who can find my app in the store so I set the "minSdkVersion" to 19 [Android 4.4] (as it is the lowest android version that supports Google Ads SDK) but the app hasn't launch and crashed at first. So, after simple searches I found this topic on Stack Overflow and the app launched successfully, but another problem raised, when I click on any wallpaper the app crashes again.

I just want to know what changes I should do to make the app compatible with Android 4.4. If the changes are simple, please direct them to this issue.
If they are too many or major changes, no problem in not making any modifications and closing this issue. Thanks.

Ads appearance enhancement

I have several suggestions regarding Ads and hope you consider them:

1- Replacing Splash interstitial Ad with "App Open Ad", Because interstitial Ad at App opening may be considered a violation to Google policies.

2- Replacing Smart Banner Ad with Normal Banner and add it to these sections:

• Home page (Wallpapers page)
• Collections page
• Favorites page
• Wallpaper activity (when the user open a single wallpaper, a Banner Ad will show inside it)

Usually Banner Ad doesn't bother the user app experience, so adding it to these section would be good for the App.

3- For Premium wallpapers, I noticed when I apply a wallpaper, there are 2 Ads will show, Reward Ad & interstitial Ad and that would be somewhat annoying for user experience, so I suggest removing interstitial Ad in Premium wallpapers.

4- I suggest Implementing interstitial Ad when the user saves a non-premium wallpaper. In that way, we will have 2 interstitial Ads, when the user saves non-premium wallpapers and when he applies them.

5- I suggest Implementing interstitial Ad after a certain number of clicks, lets say 7 clicks. Let me explain:

• When the user clicks on any wallpaper (whether it is a premium wallpaper or not), this is counted as 1 click
• When the user clicks on any collection, this is counted as 1 click

Lets say now he has 6 clicks, when he does the 7th click, an interstitial Ad will show.
I believe in that way, the user will get a good App experience and in the same time, a proper number of Ads will show. Hope you consider my suggestions and thanks a lot for your efforts.
