Open the documentation for all the libraries you are using and double check if they have any specific rules to be put in proguard since that is enabled during release build. proguard obfuscates you’re APK when making a release build, which means removing code like annotations and comments etc. which also reduces the size of the apk.
So for some libraries to work, you have to specify some rules in your proguard file to no obfuscate certain things. Common error to be careful of when maiking debug and release builds.

Gradle sync faild: Unable to find valid certification path to requested target

While creating android library in project & creating new project in android studio 3.5.1 , I got the error as Unable to find valid certification path to requested target.
I have tried lots of solutions available on stack overflow eg.,set proxy but didn't worked for me.
I exactly didn't get the solution for this error.
If anyone has solution for this error please share.
My build.gradle looks like:
apply plugin: 'com.android.application'
android {
compileSdkVersion 29
buildToolsVersion "29.0.2"
defaultConfig {
applicationId "com.example.poc1"
minSdkVersion 21
targetSdkVersion 29

App not 64 bit compliant but doesn't include native code

I've been struggling to get my app 64 bit compliant. I even tried creating a new empty app using the same package name and signing key as my old app. The new app is 100% boilerplate code and I'm getting this message after uploading it to the play store. What am I missing? I'm starting to wonder if this message is completely erroneous.
This release is not compliant with the Google Play 64-bit requirement. The following APKs or App Bundles are available to 64-bit devices, but they only have 32-bit native code: . Learn more

I've read the url provded in "Learn More." As far as I can tell, the only thing that I needed to do to the empty app was add this to the build.gradle file:
ndk.abiFilters 'armeabi-v7a','arm64-v8a','x86','x86_64'

How to set up correctly the OSMbonuspack in my project?

Hello guys I tried to install the osmbonuspack in an Android Studio project. I tried this with the osmbonuspack wiki, but when I try to sync my project I get an error in this dependency. I assume that this is a compatibility problem. Can you please suggest me a solution?
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "mytestapplication.hello.com.map"
minSdkVersion 16
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'
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 'org.osmdroid:osmdroid-android:6.0.1'
implementation 'com.github.MKergall:osmbonuspack:6.5.2'
}
-This dependency returns the error:implementation 'com.android.support:appcompat-v7:28.0.0'

SDK 28 is not compatible with appcompat-v7.
You can now upgrade to osmbonuspack 6.5.3, which get rid from this dependency to appcompat-v7.
(and also upgrade to osmdroid 6.0.3)

Cant generate aar file from project

I am new in creating library from android studio. I have been reading this tutorial in developers website. So to try it out I have created a new project and without doing anything I edited the app level build.gradle file and here is how it looks like:
apply plugin: 'com.android.library'
android {
compileSdkVersion 28
defaultConfig {
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'
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'
}
Now when I am trying to build an apk(which is supposed to build aar file) isn't building anything as I cant see any confirmation message like something when I build an apk nor can't I find anything inside app/build/outputs folder..
Where am I going wrong? Is there anything that I am understanding wrong in the tutorial?
Here is the project structure - screen shot
