And also i dont understand why initialization of SDK is not actual and it stroked. I have tried solutions which on stack. Doesn't help.
Also if any1 know the good example where Firebase and Facebook auth integrated well? Because as always firebase guide is totally collapsed my brain.

You need add
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//initialize Facebook SDK
FacebookSdk.sdkInitialize(getApplicationContext());
if (BuildConfig.DEBUG) {
FacebookSdk.setIsDebugEnabled(true);
FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
}
setContentView(R.layout.activity_main); }
Need add meta-data to Application
<application android:label = "#string/app_name" ... >
...
<meta-data android:name = "com.facebook.sdk.ApplicationId" android:value = "#string/facebook_app_id" />
...
</ application>
instead of
<activity android:name=".FacebookLoginActivity"
>
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id"/>
</activity>

You don't really need to initialize FacebookSDK manually as it gets initialized automatically, just change your manifest file as #Boris showed. Hope it will work now.

Cause of Error Message "Error:(27) Tag <manifest> attribute package has invalid type 4."

When trying to build my app, I get the following error message: "Error:(27) Tag <manifest> attribute package has invalid type 4." Any ideas on what is causing this? Here is a copy of my manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dummy.tanc">
<application
android:supportsRtl="true"
android:allowBackup="true"
android:fullBackupContent="false"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<meta-data android:name="com.google.android.gms.games.APP_ID"
android:value="#string/app_id" />
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version"/>
<activity
android:name="com.google.example.games.tanc.MainActivity"
android:label="#string/title_activity_main"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

I think it is because, in your manifest, you've set your package name (line 2) to be
package="com.dummy.tanc"
and in when defining the activity (line 18), you've used
android:name="com.google.example.games.tanc.MainActivity"
Because of this mismatch, the issue could be arising. Change the line 18 to
android:name="com.dummy.tanc.MainActivity"

It means attribute package has type float but not string.
I guess your package name contains only numbers, something like package="1.0".

Android Permission Denial: broadcasting Intent

I really do not know what is wrong, but my if widget is update by system by "APPWIDGET_UPDATE" it throws following exception. I tried several things, exporting receiver (true/false), I tried it on emulators and real phones, but it is same. I added several intent-filters, but it did not work.
11-06 20:10:10.279: W/ActivityManager(61): Permission denied: checkComponentPermission() reqUid=1000
11-06 20:10:10.279: W/ActivityManager(61): Permission Denial: broadcasting Intent { act=android.appwidget.action.APPWIDGET_UPDATE (has extras) } from com.ency.easychange (pid=1196, uid=10034) requires null due to receiver com.android.settings/com.android.settings.widget.SettingsAppWidgetProvider
My AppWidgetProvider is only declared, because I tried to eliminate possibilities, but the exception is throw before ExchangeRateWidgetProvider.onReceive() is called.
public class ExchangeRateWidgetProvider extends AppWidgetProvider {
public static final String tag = "ExchangeRateWidgetProvider";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
}
}
My Manifest:

I appreciate if you can take a look ...

Your problem lies somewhere in your Java code, where you are attempting to send the android.appwidget.action.APPWIDGET_UPDATE broadcast. That is to be broadcast by the OS, not by apps, and that is what the Permission Denial is about.

changing launching activity

i want to change my launching activity.for the moment my manifest is this:
<application android:icon="#drawable/iconbj" android:label="#string/app_name"
android:debuggable="true">
<activity android:name=".Main" android:label="#string/app_name" android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:label="DemoPlayActivity" android:name="DemoPlayActivity" android:screenOrientation="landscape"></activity>
</application>
now I have created another activity which is a splash screen and i want to launch this instead of Main so I tried this way:
<application android:icon="#drawable/iconbj" android:label="#string/app_name"
android:debuggable="true">
<activity android:name=".Splash" android:label="#string/app_name"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="Main" android:label="Main"
android:screenOrientation="landscape">
</activity>
<activity android:label="DemoPlayActivity" android:name="DemoPlayActivity"
android:screenOrientation="landscape"></activity>
</application>
but i get thisproblem with permission:
[2011-03-31 16:32:44 - BlackJackNuovo]
ActivityManager:
java.lang.SecurityException:
Permission Denial: starting Intent {
act=android.intent.action.MAIN
cat=[android.intent.category.LAUNCHER]
flg=0x10000000
cmp=com.phinet.android.blackjack/.Main
} from null (pid=-1, uid=-1) requires
null.
please help me :)
Update
NO WAY. I did this way:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.phinet.android.blackjack" android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
<application android:icon="#drawable/iconbj" android:label="#string/app_name"
android:debuggable="true">
<activity android:name="com.phinet.android.blackjack.Splash" android:label="Splash"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.phinet.android.blackjack.Main" android:label="Main"
android:screenOrientation="landscape">
</activity>
<activity android:label="com.phinet.android.blackjack.DemoPlayActivity" android:name="DemoPlayActivity"
android:screenOrientation="landscape"></activity>
</application>
</manifest>
but it seems to lunch always the Main activity,this is the concole log:
[2011-04-01 10:57:10 - BlackJackNuovo] Uploading BlackJackNuovo.apk onto device '9000d365e767'

WHY?

<activity android:name="Main" android:label="Main"
android:screenOrientation="landscape">
</activity>
<activity android:label="DemoPlayActivity" android:name="DemoPlayActivity"
android:screenOrientation="landscape"></activity>
Should still have the leading .
<activity android:name=".Main" android:label="Main" android:screenOrientation="landscape">
</activity>
<activity android:label=".DemoPlayActivity" android:name="DemoPlayActivity"android:screenOrientation="landscape">
</activity>
This is stating it has a relative path to your Classes. You could make absolute references if you wished, i.e. "com.your.app.Main"
