Android Studio : Unfortunately the app has stopped. I have found a lot of errors in the LayoutInflator.java

Question

As per the comments I have added the ActivityMain.xml file below the logcat. I am trying to build a simple app with a floating action bar in it. I don't know where I have made the mistake.

The following is the message in the logcat.

        mPrivateFactory = original.mPrivateFactory;
        setFilter(original.mFilter);
    }

   public View inflate(@LayoutRes int resource, @Nullable ViewGroup root) {

    }

@BrunoFerreira I have just added it for your reference. Thank you ! — NoviceMi, Jul 17 '17 at 16:18
@HiI'mFrogatto So does that mean I have to make a specific change in my MainActivity.Java file ? — NoviceMi, Jul 17 '17 at 16:22

android.view.InflateException: Binary XML file line #15: Error inflating class android.support.design.widget.FloatingActionButton

this is the exception. I think maybe you not imported design-library;

compile 'com.android.support:design:25.4.0'

or maybe bad attributes

EDIT UPDATE

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab_youtube"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_marginBottom="260dp"
    android:layout_marginRight="@dimen/fab_margin_right"
    app:backgroundTint="@color/Color2"
    app:elevation="6dp"
    android:src="@drawable/ic_youtube"
    android:visibility="invisible"
    app:pressedTranslationZ="12dp" />

Different line from your code is

app:backgroundTint="@color/Color2"
    app:elevation="6dp"

'com.android.support:design:25.3.1' was added to the gradle in the beginning. So it has to be bad attributes but can you help me in where to look exactly? – NoviceMi Jul 17 '17 at 16:15
com.android.support:appcompat-v25.3.1+ added support for tinting widgets on devices running pre android 5.1 (API Level 21). To make use of it make sure you extend or set the AppCompat Theme and use app:backgroundTint instead of android:backgroundTint. Also change android:elevation to app:elevation – Fr099y Jul 19 '17 at 03:12
I hope that helps. But how exactly should I make that change? Should I type it in 'styles.xml' ? And if so.. what should I type? – NoviceMi Jul 19 '17 at 14:42
Answer updated. use 'app:' instead of 'android:'. It maybe help you – Fr099y Jul 19 '17 at 15:53
but where should I use? – NoviceMi Jul 19 '17 at 20:06
Just in FloatingActionButtons. Are you cheched the my answer? I updated the answer. Copy my code and replace your FloatingActionButtons. Then check the it is working or not – Fr099y Jul 20 '17 at 03:39

i think you forgot add support compile 'com.android.support:design:25.3.1' Just add this dependencies in your gradle file like this

 dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:25.3.1'
    compile 'com.android.support:cardview-v7:25.3.1'
    compile 'com.android.support:support-v4:25.3.1'
}

I already had added the design code line to the dependencies. Nevertheless i pasted your code over mine and still no change, So what next? — NoviceMi, Jul 17 '17 at 16:17
