I am trying to use this However that gives me error .

Here is the situation. I have an app with a Google Maps fragment which works very nice when I run it on my Android Phone through USB. The maps shows as it should. But when I upload it on Google Play and install it from there, the maps is blank and the log shows: “INTERACT_ACROSS_USERS_FULL”.

I've done some searching around and I found that it is a matter of signature. From a previous thread, someone recommended to add the following in the manifest:

<permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL" android:protectionLevel="signature"/>

I have tried first with "signatureOrSystem" (from a previous thread) and now I'm trying with "signature" (waiting on Google Play now), but this is a blind thing to do, as I don't understand what it does. I also saw this:

"signature" A permission that the system grants only if the requesting application is signed with the same certificate as the application that declared the permission. If the certificates match, the system automatically grants the permission without notifying the user or asking for the user's explicit approval.

Unfortunately, I don't understand what this means. What does this mean: "if the requesting application is signed with the same certificate as the application that declared the permission".

For GooglePlay, I have created a certificate from scratch and attach it to the release.apk (Generate Signed APK). Was there a way to connect this certificate to the app itself? I'm really sorry for so many dumb questions, but I would really like to understand how to solve this issue.

Thank you in advance!

I am trying to use this However that gives me error .

I uploaded an app to Google Play Store but it is incompatible with all the devices. The app is actually a SignalR based chat application. Check out this image 

I am attaching the AndroidManifest.xml file.Any help would be appreciated.

<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>

<supports-screens 
      android:smallScreens="true" 
      android:normalScreens="true" 
      android:largeScreens="true"
      android:xlargeScreens="true"
      android:anyDensity="true" />
<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="19" 
    android:maxSdkVersion="21" />

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission     android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

 

I am using signalr library.I am using this library for a chat app in android. I firstly developed eclipse based project and use the jar files.The app is working fine.

But when i try to upload the app to the Google Play.It shows me a message that your app doesn't supports any devices. I even tried to upload the app without the libraries then it gets uploaded supports over 6K android devices.

As this library is updated for gradle for android.So i simply convert it into gradle project for android studio as well.Works perfectly but still won't supports any devices.

I am trying to use this However that gives me error .
