Seems to be one error with gradle version which I don't know how to fix.
I am using android studio. Not very knowledgeable, so will need basic instruction on how to fix this.

Failed to resolve: com.google.android.material.material:1.0

I've been trying to get the floatingActionButton to work but it seems it's not working due to my gradle dependencies, the gradle code is shown below please i need some help on this,
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "-------------"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.android.material.material:1.0.0-alpha1;'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
There's a typo in your dependency definition. Remove semi-colon at end and replace . with : between com.google.android.material and material:1.0.0-alpha1
So all together, change
implementation 'com.google.android.material.material:1.0.0-alpha1;'
To
implementation 'com.google.android.material:material:1.0.0-alpha1'

In higher android versions everything works fine. Help please )
Reduce your compile sdk version and target version to 26
and change the appcompat-v7
to the following
com.android.support:appcompat-v7:26.0.0-beta1
then check run it.
