App merge release resources error in Android Studio

I get the following errors while trying to build a signatured APK:
I've looked through ThreadPoolExecutor.java and there are some errors but when I'm editing it, it says that it's not part of the project so I'm assuming it's part of the IDE? What could be the problem?
Here's my plugin.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
applicationId 'com.riddimdub.radio'
minSdkVersion 24
targetSdkVersion 28
versionCode 1
versionName "1.3"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
}

I found the answer:
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
In the android { }

cant import some libraries in android studio

I am trying to import some libraries like Picasso, etc. but Android Studio shows up with this message.
here is the build.gradle(Module:app)
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.example.mypc.urumcafe"
minSdkVersion 17
targetSdkVersion 25
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(include: ['*.jar'], dir: 'libs')
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'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
compile 'com.android.volley:volley:1.0.0'
compile 'com.amitshekhar.android:android-networking:1.0.1'
compile 'com.android.support:design:25.3.1'
testCompile 'junit:junit:4.12'
}
I just want to import 'com.amitshekhar.android:android-networking:1.0.1'but as you can see in the uploaded image there is "failed to resolve" error.
so how can I fix this? the same story is for Picasso lib.
Thank you.

Update your build tools version to 27.0.3 and corresponding dependencies to sdk version 27.
here is the updated build.gradle and it is working perfectly.
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
buildToolsVersion "27.0.3"
defaultConfig {
applicationId "com.example.mypc.urumcafe"
minSdkVersion 17
targetSdkVersion 27
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(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',
{
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:27.1.1'
compile 'com.android.support.constraint:constraint-layout:2.+'
compile 'com.android.volley:volley:1.0.0'
compile 'com.amitshekhar.android:android-networking:1.0.1'
compile 'com.android.support:design:27.1.1'
testCompile 'junit:junit:4.12'
}

The newest version of the library is 1.0.2.
Use this and try again:
com.amitshekhar.android:android-networking:1.0.2

you might be lacking the Maven Central (or the jitpack.io for v1.0.2) repository:
allprojects {
repositories {
google()
mavenCentral()
jcenter()
}
}

Download the latest version of Android Support Repository, Android Support Library and Google Repository from your SDK Manager.
I think it should solve the issue.
