ADB throws SecurityException while starting service after system update to Nexus 7: "Caller uid=2000 is not privileged to communicate with user=-2"

I am issuing following command to Nexus 7 tablet: ``` adb.exe -s 015d2109567231a0f shell am startservice -n com.packagename/.ExServiceName --ei port 59777 ``` and getting: ``` Starting service: Intent { cmp=com.packagename/.ExServiceName (has extras) } java.lang.SecurityException: Caller uid=2000 is not privileged to communicate with user=-2 at android.os.Parcel.readException(Parcel.java:1425) at android.os.Parcel.readException(Parcel.java:1379) at android.app.ActivityManagerProxy.startService(ActivityManagerNative.java:2648) at com.android.commands.am.Am.runStartService(Am.java:415) at com.android.commands.am.Am.run(Am.java:111) at com.android.commands.am.Am.main(Am.java:82) at com.android.internal.os.RuntimeInit.nativeFinishInit(Native Method) at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:235) at dalvik.system.NativeStart.main(Native Method) ``` It all worked without problems until I applied a system update to my tablet! Current tablet information: ``` Model number: Nexus 7 Android version: 4.2 Kernel version: 3.1.10-g22b4fcd ``` Service manifest: ``` <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.packagename" android:versionCode="1" android:versionName="1.0"> <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" /> <uses-permission android:name="android.permission.INTERNET"/> <application android:label="@string/app_name" android:icon="@drawable/ic_launcher" android:theme="@style/AppTheme"> <service android:name=".ExServiceName" android:exported="true"></service> </application> </manifest> ``` I am developing under `Windows 7 x64` Can you please tell me how to make the service successfully accept the intent without throwing exceptions of any kind?
