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

The login with Twitter works ins debug, but not in release, also the size of the apk is bigger in the debug.
Where is the problem??
i have 3 activitys
this is the build.grandle

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.
I created my first android library and published it to GitHub.
Now a want to make other able to use it.
So a visited gitpack.io and followed the steps there.
The thing is, that my Gradle sync failed in the Project I want to use my lib, and the JitPack log says about a warning with missing maven plugin but build is successful.
Here my jitpack log
https://jitpack.io/com/github/ludev-studio/colorpicker-android/v1.0.0/build.log
and my libs build.gradle (module)
apply plugin: 'com.android.library'
apply plugin: 'maven'
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:support-core-utils:28.0.0"
implementation 'com.android.support:appcompat-v7:28.0.0'
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'
}
I hope you can help me!
When i build a new APK or generate a signed APK in release mode I get the following error:
Could not download kotlin-compiler.jar (com.android.tools.external.com-intellij:kotlin-compiler:26.1.4): No cached version available for offline mode
This is my Gradle code:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.caro.customelements"
minSdkVersion 23
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-rc01'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
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.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
}
I am not using Kotlin, just regular Java Android.
What should I do to fix this issue?
1) make sure you are connected to the internet.
2) go to file->settings->build, execution, deployment -> gradle -> make sure you have unchecked the "offline work" checkbox
3) rebuild the project and try build apk again
The android application has a dependency: com.googlecode.objectify
The following error is thrown while building the project:
com.android.builder.dexing.DexArchiveBuilderException: Failed to process /home/homecomp/.gradle/caches/modules-2/files-2.1/com.googlecode.objectify/objectify/5.1.16/148ca59a5f89b394eb998ce1894d222c7e11131d/objectify-5.1.16.jar

I would be very surprised if the Google App Engine SDK (which Objectify depends on) works on Android. If it did, it would certainly require the Remote API.
You might try Objectify6, which uses a newer Google SDK and REST-based API and is more likely to work on Android. You should check.
That said... directly accessing your datastore from a mobile app? Sounds like a terrible idea.
I get this error when trying to compile an android studio project, that uses the "weka" machine learning algorithm. The project is part of an uni assignment, just to be clear.
the build.gradle looks like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
applicationId "ac.univie.em2.project"
minSdkVersion 24
targetSdkVersion 26
versionCode 1

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
buildToolsVersion '26.0.2'
}
dependencies {
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.android.support:support-v4:26.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
// https://mvnrepository.com/artifact/nz.ac.waikato.cms.weka/weka-stable
implementation 'nz.ac.waikato.cms.weka:weka-stable:3.8.0'
}
Things we already tried:
1) adding the multidexenabled true flag
2) clean and rebuild
EDIT: We found a workaround, by not using maven for the weka dependency, but using the 3.6.6 jar directly. I would still love it if someone could tell me what the problem in out build.gradle file is
