I have been doing some NFC development on android, and I have hit a brick wall. I launch the app and it immediatly fails with a "Unfortunately,..... has stopped working".
Some quick googling showed I need the put the permission in the manifest. I did that, but lo and behold, I still get the same error!
Here is the start of my manifest:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<uses-permission android:name="android.permission.NFC" />
<uses-sdk android:minSdkVersion="10"/>
<uses-feature android:name="android.hardware.nfc" android:required="true" />
<activity
android:name=".MainActivity"
<!-- rest of the file --->
And the output in logcat:
java.lang.RuntimeException: Unable to resume activity {za.co.fnb.ms.nfcreader/za.co.fnb.ms.nfcreader.MainActivity}: java.lang.SecurityException: NFC permission required: Neither user 10253 nor current process has android.permission.NFC.
What am I doing wrong here?
The section
<uses-permission android:name="android.permission.NFC" />
<uses-sdk android:minSdkVersion="10"/>
<uses-feature android:name="android.hardware.nfc" android:required="true" />
Needs to be outside of your application tag.
Like
<uses-permission android:name="android.permission.NFC" />
<uses-sdk android:minSdkVersion="10"/>
<uses-feature android:name="android.hardware.nfc" android:required="true" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
...
Read Structure of the Manifest File
<uses-permission>, <uses-sdk>, and <uses-feature> go outside the <application> element:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.commonsware.android.jimmyb"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.NFC"/>
<uses-feature
android:name="android.hardware.nfc"
android:required="true"/>
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="15"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter android:label="#string/app_name">
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<data android:mimeType="vnd.secret/agent.man"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
</manifest>
(from this sample project)
Add these to activities which you use nfc:
<activity
android:name="com.example.example.CLASSNAME"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.nfc.action.TAG_DISCOVERED"/>
</intent-filter>
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<data android:mimeType="mime/type" />
</intent-filter>
<meta-data android:name="android.nfc.action.TECH_DISCOVERED"
android:resource="#xml/nfc_type"/>
</activity>
And also you have to define permissions before application tag.

I have an application that may or may not work with NFC. I have added these lines to manifest:
<manifest ...>
<uses-feature android:name="android.hardware.nfc" android:required="false"/>
<uses-permission android:name="android.permission.NFC" />
</manifest>
When I search for the application in google play, the message continues: "Your device is not compatible with this version"
I have verified that the NFCAdapter is not null, I have requested the pertinent permissions directly in execution ... but that message continues to come out.

my problem is not a bad code. I waited for one to two days and the problem was solved. It is possible that google servers did not resolve the request well and took a little longer to update. I really do not know what the reason was but my app is already working :)
My manifest gives me this error:
Element type "activity" must be followed by either attribute
specifications, ">" or "/>"
I have however opened and closed the activity tag as expected. I've also cleaned the project in an attempt to solve this problem but to no avail.
Here is my manifest.
<?xml version="1.0" encoding="utf-8"?>

your

should be
<activity

Instead of:
<activity
android:name="com.TeamX.shuttle_App.Main"
android:label="#string/app_name"
</activity>
Do this:
<activity
android:name="com.TeamX.shuttle_App.Main"

On my Main Activity i have to show the first sector block value of Mi-fare classic tag. when i hold new tag at mobile at that time app also show tag information.

Android studio , is giving me some issues. I clearly declared android. permission.GET_TASKS in the manifest. But it still closes the app.
Error:

Move your permission Tag outside of Application Tag
<uses-sdk
android:minSdkVersion="16"
android:targetSdkVersion="16" />
<uses-permission android:name="android.permission.GET_TASKS"/>
<application
android:icon="#drawable/ic_launcher"
<!--Elements inside application Tag-->

As I've read here, here and here, I've done :
1) copied all the drawables from #android/drawable to my corresponding folders hdpi, mdpi, e.t.c -
so I havn't any icon from #android/drawable folder in the project
2) put the icon drawable to the drawable folder of the res
3) cleaned the project
What can be solution for this ?
I think it is linked to having the icon attribute setting to a color #android:color/transparent. Maybe try a transparent drawable rather than a color.
I've found the solution - it was in
<activity
....
android:icon="#android:color/transparent" - the problem string
...
</activity>
when I removed that string, everythins worked fine
