Google Maps Android v2 Authorization failure

I am testing the sample google code on an actual device having 2.3.6.I thought it might be the problem with the key ,so I created different key on a different account through Google's API Console.Still the same problem "Google Maps Android API-Authorization Failure". Here is the log: ``` 12-07 10:31:30.476: D/dalvikvm(17791): DexOpt: couldn't find field Landroid/content/res/Configuration;.smallestScreenWidthDp 12-07 10:31:30.484: W/dalvikvm(17791): VFY: unable to resolve instance field 24 12-07 10:31:30.484: D/dalvikvm(17791): VFY: replacing opcode 0x52 at 0x0012 12-07 10:31:30.484: D/dalvikvm(17791): VFY: dead code 0x0014-0018 in Lcom/google/android/gms/common/GooglePlayServicesUtil;.b (Landroid/content/res/Resources;)Z 12-07 10:31:30.718: D/dalvikvm(17791): GC_CONCURRENT freed 197K, 46% free 3063K/5639K, external 408K/517K, paused 3ms+4ms 12-07 10:31:30.789: W/dalvikvm(17791): Unable to resolve superclass of Lmaps/a/du; (411) 12-07 10:31:30.789: W/dalvikvm(17791): Link of class 'Lmaps/a/du;' failed 12-07 10:31:30.789: W/dalvikvm(17791): Unable to resolve superclass of Lmaps/a/ej; (2363) 12-07 10:31:30.789: W/dalvikvm(17791): Link of class 'Lmaps/a/ej;' failed 12-07 10:31:30.789: W/dalvikvm(17791): Unable to resolve superclass of Lmaps/j/k; (2379) 12-07 10:31:30.789: W/dalvikvm(17791): Link of class 'Lmaps/j/k;' failed 12-07 10:31:30.789: E/dalvikvm(17791): Could not find class 'maps.j.k', referenced from method maps.y.ae.a 12-07 10:31:30.789: W/dalvikvm(17791): VFY: unable to resolve new-instance 3571 (Lmaps/j/k;) in Lmaps/y/ae; 12-07 10:31:30.789: D/dalvikvm(17791): VFY: replacing opcode 0x22 at 0x007d 12-07 10:31:30.820: D/dalvikvm(17791): VFY: dead code 0x007f-008f in Lmaps/y/ae;.a (Landroid/view/LayoutInflater;Lcom/google/android/gms/maps/GoogleMapOptions;Z)Lmaps/y/ae; 12-07 10:31:31.281: D/dalvikvm(17791): GC_CONCURRENT freed 297K, 46% free 3222K/5959K, external 408K/517K, paused 3ms+4ms 12-07 10:31:31.523: D/dalvikvm(17791): GC_EXTERNAL_ALLOC freed 227K, 45% free 3397K/6087K, external 431K/517K, paused 52ms 12-07 10:31:31.648: I/System.out(17791): 0 12-07 10:31:31.734: D/dalvikvm(17791): GC_CONCURRENT freed 188K, 43% free 3531K/6151K, external 544K/1029K, paused 5ms+4ms 12-07 10:31:32.125: D/libEGL(17791): loaded /system/lib/egl/libGLES_hgl.so 12-07 10:31:32.132: D/BRCM_EGL(17791): eglCreateContext() context: 0xd7090, VC context 1, Thread 17810 12-07 10:31:32.148: D/BRCM_EGL(17791): eglCreateWindowSurface() surface: 0xd70d0, VC surface: 1, Thread: 17810 12-07 10:31:32.148: D/BRCM_EGL(17791): eglMakeCurrent(0xd7090, 0xd70d0, 0xd70d0) Thread: 17810 12-07 10:31:32.859: E/Google Maps Android API(17791): Authorization failure. ``` Here's is my manifest: ``` <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.smartapps4u.googlemapslib" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" /> <uses-feature android:glEsVersion="0x00020000" android:required="true"/> <permission android:name="com.smartapps4u.googlemapslib.permission.MAPS_RECEIVE" android:protectionLevel="signature"/> <uses-permission android:name="com.smartapps4u.googlemapslib.permission.MAPS_RECEIVE"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/> <uses-library android:name="com.google.android.maps" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="My API key"/> <activity android:name=".MainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> ``` Any help would be appreciated.
