If the app names are the same the reason can be using multiple launcher intent in your manifest file. Check your merged manifest file instead of application manifest file.

i think u must have used this intent filter twice in multiple activities.check your manifest file

Why Custom Launcher doesn't work properly sometimes?

I created a custom launcher and set it to default launcher for my tablet. but when I open an application and then press Back button I will go to the last launcher(Default launcher of Samsung) although I setup my launcher as default before!
This is my launcher manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

No device supported for my app on Google Play Developer Console

I'm having trouble with the Google Play store that insists that my app is supported by 0 devices.
I've tested my app on different devices and it works very well, there's no reason for it to be incompatible with every single Android device.
Thanks in advance
This is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</manifest>
The 4 features being
android.hardware.CAMERA
android.hardware.CAMERA2
android.hardware.FAKETOUCH
android.hardware.PORTRAIT
And 3 permissions
android.permission.CAMERA
android.permission.READ_EXTERNAL_STORAGE
android.permission.WRITE_EXTERNAL_STORAGE
Google Play Resume

Looking at https://github.com/googlesamples/android-Camera2Basic/blob/master/Application/src/main/AndroidManifest.xml I'm pretty sure <uses-feature android:name="android.hardware.camera2" /> is not really a thing. Try changing it to <uses-feature android:name="android.hardware.camera" /> or remove it.

How To Avoid Google Play Services Update Required Warning

I'm using Google Maps in my Android app and I'm seeing the following message on some older devices:
I understand the nature of this message and that updating will resolve this issue.
However I would like to avoid users seeing this all together, and just want the map to load on all devices.
Here's what my dependencies look like:
Please note that I added individual parts of Google Play services that I needed rather than the full library as I started receiving an error from Android Studio about too many lines of code - this was the work around as I just have to many libraries as it seems.

Ideally I would like to know how to have the map just load and not force the user to update as my minSDK=10 and the app supports Android 2.3 devices and up.
Even if that means targeting a lower version of Google Play services to support SDK 10+ I'm ok with that solution.
Thanks!

However I would like to avoid users seeing this all together, and just want the map to load on all devices.
Then don't use Maps V2. Instead, use some other mapping solution (e.g., Open Street Map).
Otherwise, there is no "magic" dependency that will avoid this dialog on all devices. While you are welcome to use some older version of that play-services-maps dependency, there is no guarantee that ~1.5 billion devices will all support that particular version of the Play Services engine without any updates.

App working on my device but when I publish it to Google Play Store for Beta Testing not working

Yesterday I published my app on the Google Play Store as Beta Testing. When I run it from Eclipse on my device it works great, but when I download it from the Google Play Store it doesn't work.
The first screen is an Splash Fragment which shows the Facebook Login button, when I click it it asks for the permissions and then it goes back to the Splash Fragment (It should hide the Fragment).
I tested it on another device and it hides the Splash Fragment, enters to the MainActivity and it tells me that I am not online.
I don't underestand why it does work when I run it from my Eclipse but it doesn't work when I run the version that I download from the Google Play Store.

Google Maps requires that the API key be built to the Application Signing Key. That means that the Maps API key you use for debugging (running through Eclipse) will be different than the Maps API key which will work on apps exported from Eclipse and signed to post on the Play Store. All you need to do is get an updated Maps API key using the same key you sign your app with!
Also, see this for a method of creating one Maps API key for both Debug and Release versions of your signed package.

Make sure your facebook app is in live mode.
