Vector drawables not loading in xml ResourceNotFoundException

I am having trouble with loading vector files in my splash background xml file. The vector has been loaded successfully because I can open the vector file in android studio and I get a small graphic of the vector on the side of the xml file. However, the design view of the xml file shows an error for the vector file, and I get a ResourceNotFoundException when trying to run my app.
Code below:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:opacity="opaque">
<item android:drawable="#color/colorPrimary"/>
<item>
<bitmap
android:gravity="center"
android:src="#drawable/ic_loading_screen_logo"/>
</item>
</layer-list>
splash background.xml
My grade version is classpath 'com.android.tools.build:gradle:4.0.1'
and I have included the following line in my grade app file vectorDrawables.useSupportLibrary = true
It seems that any vector file that I use has this error, so there is some setting of some sort that is missing.
Please assist in anyway.
Thanks,

The problem is wrapping the xml drawable in a <bitmap/>
Try this:
Replace
<item>
<bitmap
android:gravity="center"
android:src="#drawable/ic_loading_screen_logo"/>
</item>
With:
<item android:gravity="center"
android:drawable="#drawable/ic_loading_screen_logo"/>

replace <bitmap to <item
make sure that your vector is in drawable folder not in drawable-24.
check vectory path may be its too long.

Android not recognizing string resource

In my android app, I have a string
<string name="action_upload">Upload Image</string>
in the strings file. Then in a menu file I have
navigation_screen.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context="android.arin.NavigationScreen" >
<item
android:id="#+id/action_upload"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/action_upload"/>
<item
android:id="#+id/action_forward"
android:icon="#drawable/ic_action_forward"
android:title="#string/action_forward"
android:showAsAction="ifRoom" />
</menu>
However when I try to run it, I get an error saying:
[2014-06-19 17:26:18 - ARIN] W/ResourceType( 9060): ResXMLTree_node size 0 is smaller than header size 0x100.
[2014-06-19 17:20:26 - ARIN] C:\Users\NAME\Documents\NAME\NAME\ARIN\res\menu\navigation_screen.xml:5: error: Error: No resource found that matches the given name (at 'title' with value '#string/action_upload').
I even tried a Project clean in eclipse, but still problem persists.
Does anyone know how to fix it?
Thanks

This may seem like a weird answer, but did you save the xml file. Hit Ctrl-S and try it again.
If that doesn't work: Are the other strings you declared in the strings.xml file visible?

error: Multiple annotations found at this line:

I am implementing searchview in my app, for which I copied this options_menu.xml from a separate working project of searchview.
I get this error in res/menu/options_menu.xml
Multiple annotations found at this line:
- error: No resource identifier found for attribute 'actionViewClass' in package
'com.example.indianconstitution'
- error: No resource identifier found for attribute 'showAsAction' in package
'com.example.indianconstitution'
Code:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/action_search" // error in this line
android:icon="#drawable/ic_launcher"
android:title="#string/action_search"
yourapp:actionViewClass="android.support.v7.widget.SearchView"
yourapp:showAsAction="always" />
</menu>
Can anyone figure out this problem?
Thanks in advance...

Looks like you copied this from a project that uses appcompat-v7 into one that doesn't.
Either include appcompat-v7, following the instructions, or just replace yourapp:x attributes with android:x attributes. If you go this way, though, you should also replace the action view class with the corresponding one in the framework (i.e. android.widget.SearchView).

color-palette or third party plugin in order to set colors in eclipse

Is there easy way to manipulate colors in android ?
In dot.net we have color palette to change the color of
objects(button-background,text-color.. etc)
similarly is there any color palette/or/-any-plugins in object
browser of eclipse IDE at design time
Note:: I am aware of changing the color by adding color codes in styles.xml and referencing it in layout.xml

You can do this in some cases directly,
e.g in TextView you can change the Text Color by applying this statement in
Java code
textView1.setTextColor(Color.Red);
for other objects like buttons etc. you can not change their Color Directly like C#.
You have to create different .xml file and then you will store this .xml file inb drawable folder, in your activity_main(where button is created in your layout file) you have to make reference
e.g
<Button
android:background="#drawable/red_button" />
now the colored button .xml file located in
res/drawable/red_button.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#drawable/red_button_pressed" />
<item android:state_focused="true" android:drawable="#drawable/red_button_focus" />
<item android:drawable="#drawable/red_button_rest" />
</selector>

Android [string array] cannot be resolved or is not a field

I'm getting an error about a string array (located in strings.xml) not being able to be resolved.
I've done everything the internet says:
Restarted Eclipse
Deleted my R.java file inside the gen folder
My values folder is still inside the res folder, not moved
None of my XML files have erros
Ran Project -> Clean
I don't have android.R imported in my class.
Checked the R.java class, it indeed doesn't have an app_categories property (my array's name)
The relevant part of the XML:
<string-array name="app_categories">
<item >Cat 1</item>
<item >Cat 2</item>
<item >Cat 3</item>
<item >Cat 4</item>
<item >Cat 5</item>
<item >Cat 6</item>
<item >Cat 7</item>
<item >Cat 8</item>
<item >Cat 9</item>
</string-array>
The Java code:
String[] categoryNames = getResources().getStringArray(R.string.app_categories);
All my other strings are visible. I have another array defined just like this one, and that one isn't visible either.
Exact error below:
app_categories cannot be resolved or is not a field [class_name].java [path] line 45 Java Problem

Just try out this way :
getResources().getString(R.array.app_categories_list);
Instead of R.string use R.array you will get your arraylist.

Don't put your string arrays in strings.xml You must create a new file called arrays.xml and place them there.
And when calling you need R.arrays.myarray, not R.strings.MyArray

After cleaning your project try restarting the adb server by running adb kill-server and adb start-server from the command line

a solution may be to create the R manually:
just hover over the error in the activity file where the problem was and then manually create it, which will cause R to generate the string array you created in strings.xml
