How can I fix "Could not GET jcenter.bintray.com/com/google/dagger/dagger-android-processor/2.35.1/dagger-android-processor-2.35.1.pom"?

I'm practicing Dagger 2 from this tutorial:
vogella.com Dagger tutorial.
But I got this error while running my Android project:
Could not GET 'https://jcenter.bintray.com/com/google/dagger/dagger-android-processor/2.35.1/dagger-android-processor-2.35.1.pom'
How can I fix this issue?
This is my build.gradle Module:
plugins {
id 'com.android.application'
}
android {
compileSdkVersion 31
buildToolsVersion "31.0.0"
defaultConfig {
applicationId "com.vogella.android.dagger2simple"
minSdkVersion 17
targetSdkVersion 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'com.google.android.material:material:1.4.0'

}
android {
configurations.all {
resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
}
}

Replace jcenter() with mavenCentral() in all your build.gradle files.
As mentioned in migrating away from JCenter guide

Unable to include dependence library when export aar file

I created a module and now I am trying to export the .aar file but I cannot include the gradle dependencies I used in the module to the .aar file. I tried the solution of this post with no success. Here is how my app level .build file looks like:
apply plugin: 'com.android.library'
android {
compileSdkVersion 28
buildToolsVersion "29.0.2"
defaultConfig {
minSdkVersion 19
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
consumerProguardFiles 'consumer-rules.pro'
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility = 1.8
targetCompatibility = 1.8
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'

implementation ('com.google.android.exoplayer:exoplayer-core:2.10.0')
{transitive=true}
implementation ('tyrantgit:explosionfield:1.0.1')
{transitive=true}
}
What am I missing?

I don't know if this is what is resulting to the apps crashing in some phones

Set the min SDK version within your project's AndroidManifest.xml file:
<uses-sdk android:minSdkVersion="21"/>

Android Error: "File 'root/res/drawable-mdpi/popup_bottom_medium.9.png' uses reserved file or directory name 'res'."

My Android project has error while producing signed APK as below.
File 'root/res/drawable-mdpi/popup_bottom_medium.9.png' uses reserved file or directory name 'res'.ere
It didn't appear when I make APK without sining.
I found popup_bottom_medium is in android sdk (android-28) but I dont know why the error is happening on this specific file.
Please kindly help us
let me put build.gradle in our code. Actually in this project, we using two self-made library. so totally we have three build.gradle.

I put my 9-patch files in the drawable folder, not the drawable-mdpi etc... folders. Try that and see if it helps.

file name change. eg popup_bottom_medium_9.png

getTitle,getDescription,createPendingIntent(), getLargeIcon() missing in Playback Notifications with ExoPlayer

I am trying to implement Playback Notifications with ExoPlayer. But getTitle,getDescription,createPendingIntent(), getLargeIcon are missing and android studio is showing red (Cannot resolve method). How can i get these?
I wrote my code exactly same as the link. I tried it multiple times.
This is my build.gradle file (if required):
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.mediaplayertest"
minSdkVersion 18
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
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'
implementation "com.android.support:support-media-compat:28.0.0"
implementation "com.android.support:support-compat:28.0.0"
implementation 'com.google.android.exoplayer:exoplayer:2.9.5'
}

You need to define the gradle implementation correctly.
From The hello world example
implementation 'com.google.android.exoplayer:exoplayer-core:2.X.X'
implementation 'com.google.android.exoplayer:exoplayer-dash:2.X.X'
implementation 'com.google.android.exoplayer:exoplayer-ui:2.X.X'
In your gradle build script you have asked for the just "exoplayer"
NOTE: that for the PlaybackNotificationManager class you will need exoplayer-ui meaning for that particular class you would just need
implementation 'com.google.android.exoplayer:exoplayer-ui:2.9.5' but I would also include exoplayer-core
