Android Studio suddenly can't find ANY drawable components

Like the title suggests, all of a sudden, my Android Studio projects simply can't locate any of my drawable resources that I call when using android:background="#drawable/serving_editor_background" for example, it'll just give me this error code for every single drawable that has been called:
AAPT: error: resource drawable/serving_editor_background (aka com.example.poop123:drawable/serving_editor_background) not found.
Execution failed for task ':app:mergeDebugResources'.
> com.android.build.gradle.tasks.ResourceException (no error message)
ParseError at [row,col]:[2,6]
Message: The processing instruction target matching "[xX][mM][lL]" is not allowed.
It literally does it for every single one (with their respective names and file path), all of the ones that used to work up until now, not a single one works, and I never changed anything in the gradle, but I'll still provide it:

I'm getting really frustrated at this, because I changed absolutely nothing (just a specific XML code for a certain activity), and now none of the drawables can be found.
If any more info, let me know.

Bascially, I loaded up an old version of the project, copy pasted all the new code into the current project, noticed that on one of the drawable's, I had an extra
<?xml version="1.0" encoding="utf-8"?>
And for some reason it completely clogged up the whole thing, and the exception messages it gave, had 0 to do with it in a sense, had to manually find the problem myself.

First of all locate the drawable folder of your project and see the resources. if you found the resources try android:src="#drawable/resource"

Android Studio can't find resource and resource linking failed

Recently I had problems with AAPT2. The problems were caused by my username that contained non-ascii characters. I created another Windows account(without non-ascii characters) and installed Android Studio on it. Then I opened my older project and when AS asked me to update I agreed to that. Now when I try to build my app I get these errors:
Android resource linking failed
D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-v28\values-v28.xml:7: error: resource android:attr/dialogCornerRadius not found.
D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-v28\values-v28.xml:11: error: resource android:attr/dialogCornerRadius not found.

D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:2971: error: resource android:attr/ttcIndex not found.
error: failed linking references.
Most of threads I found of StackOverflow suggest that this problem might be related to support library, they say that version of it might be wrong. How could I change the version? My project also uses OpenCV library and configuration of it might be invalid.
What I tried already was cleaning and rebuilding project and adjusting compileSDKVersion in Gradle.

Also below is my build.gradle file app module. In this file in sub-clause 'dependencies' entries with support library are underlined and AS shows me a warning:
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 26.1.0. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:customtabs:26.1.0
I tried changing versions to newer or older but this warning still appears.

}

implementation 'com.android.support.constraint:constraint-layout:+'
}

I had the same error fixed it by updating the compilesdkversion to 28, since currently my build tools version is 28.0.3 , hence the version should be same as to have a perfect build.
Also check for your implementation 'com.android.support:appcompat-v7:28.0.0'
Change the respective Dependency versions to 28, it will prevent run time crashing

Tried adding all kinds of dependencies but it didn't fix it. Anyone has an idea?
EDIT: After commenting out all Firebase dependencies there is no error. Does anyone know why? Is there a way to use Firebase's storage without the error?

Android library card.io skipping camera and not scanning card on Moto X 2nd Gen

I'm trying to use the fantastic card.io library to scan credit cards just like Über manages to do on my Moto X 2nd Gen and the library is not working. It gives the following output on Android Monitor:
I/card.io: card.io 5.4.2 09/27/2016 11:38:46 -0500
E/card.io: Failed to load native library: dlopen failed: cannot locate symbol "__aeabi_memcpy"
referenced by "/data/app/br.com.feliperochamachado.cardscantest-2/lib/arm/libcardioDecider.so"...
I/card.io: Processor not Supported. Skipping camera.
Since Über does work properly on this same phone, and it does use card.io, I believe it is a problem with my setup, but it is a very simple test app that only try to reproduce the barebones guidelines to get it working. Here is my gradle.build file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.0"
defaultConfig {
applicationId "br.com.feliperochamachado.cardscantest"
minSdkVersion 19
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
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-v7:24.1.1'
compile 'io.card:android-sdk:5.4.2'
testCompile 'junit:junit:4.12'
}
And here is my manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="br.com.feliperochamachado.cardscantest">
<!-- Permission to vibrate - recommended, allows vibration feedback on scan -->

<uses-feature android:name="android.hardware.camera.flash" android:required="false" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"

android:theme="#style/AppTheme">

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Activities responsible for gathering payment info -->
<activity android:name="io.card.payment.CardIOActivity" android:configChanges="keyboardHidden|orientation" />
<activity android:name="io.card.payment.DataEntryActivity" />
</application>
</manifest>
The code that calls the scanning activity follows:
public void onScanPress(View v) {
Intent scanIntent = new Intent(this, CardIOActivity.class);
// customize these values to suit your needs.
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true); // default: false
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_CVV, false); // default: false
scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_POSTAL_CODE, false); // default: false
// MY_SCAN_REQUEST_CODE is arbitrary and is only used within this activity.
startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);
}
And my layout is very simple:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:orientation="vertical"
tools:context="br.com.feliperochamachado.cardscantest.MainActivity">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Scan Card"
android:onClick="onScanPress"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</LinearLayout>
Clicking on the button will write the aforementioned warnings to the Android Monitor, skip using the camera altogether, and display a data entry form instead.
I can't find what is wrong. Perhaps the library SDK is not bundling the needed libs, but I don't even know where to look to check it out!
Importing the SampleApp inside the SDK into Android Studio 2.2.2 gives the same result!

I've commented on two issues on the card.io github projects:
https://github.com/card-io/card.io-Android-SDK/issues/166
https://github.com/card-io/card.io-Android-source/issues/100
The sample app worked fine on a Moto X 1st Gen device.
Since ÜBER does work correctly on my device, I've tried to downgrade the library version and it did work correctly with the version 5.4.0. Just had to change my gradle dependcies to 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-v7:24.1.1'
compile 'io.card:android-sdk:5.4.2'
testCompile 'junit:junit:4.12'
}
I'll be giving this feedback on card.io's issue tracker on github.
EDIT: It also works fine with version 5.4.1!

java.lang.NoClassDefFoundError: com.google.android.gms.R$string

I am having a little trouble with the complier,
Same code I use on Nexus 5, no error.
as Soon as I use it in Tablet, it crash right away and the error said
java.lang.NoClassDefFoundError: com.google.android.gms.R$string
with brunch of unknown source...
and if i remove
multiDexEnabled true
and remove
compile 'org.twitter4j:twitter4j-core:4.0.2'
then it works on both, does anybody know the reason why?
Below is my build.grade
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.package.name"
minSdkVersion 16

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
and then a lot of activities

I look into my code many time, and I look at each library I am using and I was able to fix it.
First, like #BrainMiz said mutiDexEnabled should set it off. I just comment it instead of set it as false.
defaultConfig {
applicationId "com.package.name"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
//multiDexEnabled true
}
Second, it is the dependencies.
Since I don't have any jar in my libs folder I remove
compile fileTree(dir: 'libs', include: ['*.jar'])
also remove all not being used gms library, only add the one that being used. I have to give some credits to #Radix because I did found some error in my code regarding to the code that where I check if the device has google play store.
dependencies {
//compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'org.twitter4j:twitter4j-core:4.0.2'
compile 'com.android.support:multidex:1.0.1'
compile 'com.android.support:appcompat-v7:23.1.1'
//compile 'com.google.android.gms:play-services:8.4.0'
compile 'com.android.support:design:23.1.1'
compile 'com.squareup.okhttp:okhttp:2.5.0'
//compile 'com.android.support:support-v4:23.1.1'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.isseiaoki:simplecropview:1.0.8'
compile 'com.qozix:tileview:2.0.7'
compile 'com.android.support:cardview-v7:23.1.1'
compile 'com.google.android.gms:play-services-gcm:8.4.0'
}

I believe you should try turning multiDexEnabled false and get rid of the compile 'com.google.android.gms:play-services-gcm:8.4.0' . You have two play-services which forces you to turn multiDexEnabled to true

Change this line
<uses-permission
android:name="com.google.android.c2dm.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
with this
<permission android:name="<your-package-name>.permission.C2D_MESSAGE"

Also i see a lot of anomaly in your manifest with respect to how you have declared GCM . Have a look at the technical docs.

Got the same problem.. just clean the project, then make it and finally run it

In my case, I changed the theme of my app in the AndroidManifest.xml file and cleared out my styles.xml file (because I'm a noob and hoped to just use an out-of-the-box android theme). After launching the app, I assume there were zombie references to the old theme that caused the error because, after reverting my changes, the error disappeared.

I did remove
compile 'com.android.support:multidex:1.0.1'
and sync project. After added this line and synced again. Next, cleaned project to remove old dex files (may cause problem with dex archives merging), and it helped.

I had the same issue
Had in gradle.build dependencies :
compile 'com.android.support:multidex:1.0.0'
And in AndroidManifest.xml :
<application
...
android:name="android.support.multidex.MultiDexApplication">

Having same issue and was stuck for a whole day. Finally got solution.
Add in your app level gradle.build:
repositories {
jcenter()
}
dependencies {
compile 'com.google.android:multidex:0.1'
}
Then override attachBaseContext in your Application class like below:
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
And don't forgot to enable mutlidex support as below:
android {
...
defaultConfig {
...
multiDexEnabled true
}
}
