Answer 1

According to your problem

java.lang.IllegalArgumentException: DrawerLayout must be measured with MeasureSpec.EXACTLY

So you should set EXACTLY width to your DrawerLayout .

You can set android:layout_width="match_parent" and try again .

Change

<android.support.v4.widget.DrawerLayout
            android:id="@+id/navigation_Drawerlayout"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            tools:openDrawer="start">
            <include layout="@layout/navigation_drawerlayout" />

to

<android.support.v4.widget.DrawerLayout
            android:id="@+id/navigation_Drawerlayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            tools:openDrawer="start">
            <include layout="@layout/navigation_drawerlayout" />
