Lint found fatal errors while assembling a release target - gradle error?

I am using AS 3.1 with gradle-4.5-all.zip and main build.gradle:
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
}
}
allprojects {
repositories {
jcenter()
google()
}
}
An app-level build.gradle looks like following:
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
buildToolsVersion "27.0.3"
useLibrary 'org.apache.http.legacy'
defaultConfig {
applicationId "com.example"
minSdkVersion 14
targetSdkVersion 27
versionCode 6
versionName "1.00"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
implementation 'ch.acra:acra:4.6.1'
implementation 'commons-validator:commons-validator:1.5.0'
implementation 'com.android.support:support-v13:27.1.1'
implementation 'com.google.code.gson:gson:2.8.0'
implementation 'com.nineoldandroids:library:2.4.0'
implementation 'com.google.zxing:core:3.3.0'
}
and works fine when I set up a debug version under AS 3.1 to my phone, but when I try to make release apk it shows me an error:
Lint found fatal errors while assembling a release target.
To proceed, either fix the issues identified by lint, or modify your build
script as follows:
...
android {
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
}
As I can see in the lint-results-release-fatal.html the reason is:
I would not like to change lintOptions to supress this error because it doesn't solve the problem, it just hide it. More over, when I use
implementation files('libs/commons-validator-1.5.0.jar')
instead of
implementation 'commons-validator:commons-validator:1.5.0'
the release apk is compiled without any error messages. Is it a some gradle bug or what!?
P.S. I have attached a file androidDependencies.txt. Package commons-logging doesn't appears in the dependencies at all! How is it possible to get the solution of above problem analysing this file?

the release apk is compiled without any error messages. Is it a some
gradle bug or what!?
It seems like that dependency has a package which conflicts with the Android itself. The reason why it works without implementation and adding it manually, it might be that it downloads needed packages when you add it to be downloaded from maven repository and that's when the issue came up.
Anyways, the solution at these situations might be using the latest version:
implementation 'commons-validator:commons-validator:1.6'
Or, exclude it as follows:
implementation ('commons-validator:commons-validator:1.5.0') {
exclude group: 'commons-logging', module: 'commons-logging'
}
Note: The following part can't be helpful (for this issue) since the error says:
Commons-logging defines classes that conflict with classes now
provided by Android
You could go deeply by running ./gradlew app:dependencies in the IDE terminal to see which one conflicts with the Android itself and then excluding it as above.

MultiDexApplication not found at app launch [duplicate]

I'm trying the new MultiDex Support on my app and so far I've managed to compile my app correctly, but when running it, I get the following exception:
java.lang.RuntimeException: Unable to instantiate application android.support.multidex.MultiDexApplication: java.lang.ClassNotFoundException: Didn't find class "android.support.multidex.MultiDexApplication" on path: DexPathList[[zip file "/data/app/me.myapp.main-2.apk"],nativeLibraryDirectories=[/data/app-lib/me..main-2, /vendor/lib, /system/lib]]

This is my gradle file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.0"
defaultConfig {
minSdkVersion 16
targetSdkVersion 21
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
debug {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
packagingOptions {
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
}
repositories {
mavenCentral()
mavenLocal()
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:support-v4:21.0.0'
compile 'com.android.support:support-v13:21.0.0'
compile 'com.android.support:appcompat-v7:21.0.0'
}
And my AndroidManifest.xml:
<application
android:name="android.support.multidex.MultiDexApplication">
I don't understand what the problem is. I think I'm doing everything according to the documentation. Is there something else i am missing? I made sure I had the latest support library and repo installed from the SDK manager.

The solution didn't help me because I was using jetpack version ie androidx. libraries.
Followed official doc.
And
I had to change name to androidx....Multidex.
<application
android:name="androidx.multidex.MultiDexApplication" >
...
</application>
Hope It helps other people looking for adding multidex with jetpack.

In my case its solved by changes below code in Manifest from
android:name="android.support.multidex.MultiDexApplication"
to
android:name="androidx.multidex.MultiDexApplication"

My configuration:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.14.+' // 0.14.1, 2014-11-6
}
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}
android {
compileSdkVersion = 21
buildToolsVersion = "21.1.0"
defaultConfig {
minSdkVersion 14
targetSdkVersion 21
multiDexEnabled true
}
}
Unfortunately, I have the same problem. But I found a strange situation:
build/intermediates/dex/debug:
-rw-rw-r-- 1 andrew andrew 2221176 Nov 6 20:18 classes2.dex
-rw-rw-r-- 1 andrew andrew 8357596 Nov 6 20:18 classes.dex
unzip apk, build/outputs/apk:
-rw-rw-r-- 1 andrew andrew 8357596 Nov 6 20:18 classes2.dex
-rw-rw-r-- 1 andrew andrew 2221176 Nov 6 20:18 classes.dex
In apk, the main classes of classes.dex should be bigger than classes2.dex, but its not. I do also dex2jar & unzip jar to check classes, the application class is not there in classes.dex, its in classes2.dex contrarily.
However, I should have fixed it. Here is my patched android gradle plugin you can try:
buildscript {
repositories {
mavenCentral()
maven { url 'https://github.com/yongjhih/android-gradle-plugin.m2/raw/master/' }
}
dependencies {
classpath 'com.infstory.tools.build:gradle:0.14.+'
}
}
The patch is in: https://github.com/yongjhih/android-gradle-plugin/commit/9c2212e3b1b4c6e1f7b47f2086aba1903a6258bf
or
https://android-review.googlesource.com/#/c/113331/
issue: https://code.google.com/p/android/issues/detail?id=78761
The official patch is https://android-review.googlesource.com/#/c/113201/ that already been merged, I think it might be fixed in next version.
Already been fixed 0.14.2 (2014/11/10). (from http://tools.android.com/tech-docs/new-build-system)
Release notes:
0.14.2 (2014/11/10)
Fix potential multi-dex issue where the dex files could be renamed during packaging, leading to the wrong main dex file being used.
Fix versionNameSuffix support
Fix BuildType.initWith to copy shrinkResources flag
setup default proguard rule file if none are provided (SDK/tools/proguard/proguard-android.txt)
BuildType.pseudoLocalesEnabled flag to include fake locales in apk.

Setting up your app project to use a multidex configuration requires that you make the following modifications to your app project, depending on the minimum Android version your app supports.
If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in your module-level build.gradle file, as shown here:
android {
defaultConfig {
...
minSdkVersion 21
targetSdkVersion 26
multiDexEnabled true
}
...
}
However, if your minSdkVersion is set to 20 or lower, then you must use the multidex support library as follows:
Modify the module-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:
android {
defaultConfig {
...
minSdkVersion 15
targetSdkVersion 26
multiDexEnabled true
}
...
}
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
Depending on whether you override the Application class, perform one of the following:
If you do not override the Application class, edit your manifest file to set android:name in the tag as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<application
android:name="android.support.multidex.MultiDexApplication" >
...
</application>
</manifest>
If you do override the Application class, change it to extend MultiDexApplication (if possible) as follows:
public class MyApplication extends MultiDexApplication { ... }
Or if you do override the Application class but it's not possible to change the base class, then you can instead override the attachBaseContext() method and call MultiDex.install(this) to enable multidex:
public class MyApplication extends SomeOtherApplication {
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}

I recently had this issue. Despite no change to my configuration this error started occurring. I tried all of the suggested solutions including deleting the virtual device and creating a fresh one.
However, I did notice that if I built an APK and dragged it into the emulator to install, it worked fine.
In the end cleaning the project and re-running and then it worked.

For me, the answer was to switch to the androidx versions
android:name="androidx.multidex.MultiDexApplication"
implementation "androidx.multidex:multidex:2.0.1"

I was using the latest Android Studio and following the official document to add support to multidex https://developer.android.com/studio/build/multidex.html . But I still got the same exception. I spent a lot of time solving it. At last, I found the cause was I enabled "Java Exception Breakpoints - Any exception", and "Exception Breakpoints - When any is thrown". After I disabled them, the app ran without problems.
Just follow the official document about multidex https://developer.android.com/studio/build/multidex.html . It works.

Delete ./gradle .idea and build directory
Clean project
Uninstall app if already install on device and again install

In my case I just changed the build.gradle and I leaved the AndroidManifest like that:
android:name=".MainApplication"
I am using React Native.

i jaust changed
in manifest application
android:name="android.support.multidex.MultiDexApplication"
to
android:name="androidx.multidex.MultiDexApplication"
and it's working fine

This worked for me.
File -> Sync Project with Grandle Files

Very strange, I got same error message, but after I fixed some gradle lines it worked. Maybe it helps somebody:
Project build.gradle:
from:
..
dependencies {
// Android Gradle Plugin
classpath 'com.android.tools.build:gradle:3.2.1'
// Analytics
**classpath 'com.google.gms:google-services:3.0.0'**
}
..
to:
..
dependencies {
// Android Gradle Plugin
classpath 'com.android.tools.build:gradle:3.2.1'
// Analytics
**classpath 'com.google.gms:google-services:3.2.1'**
}
..
In the module build.gradle:
from:
..
dependencies {
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.android.support:support-compat:26.1.0'
implementation 'com.android.support:appcompat-v7:26.1.0'
**implementation 'com.google.android.gms:play-services-analytics:12.0.1'**
}
..
to:
..
dependencies {
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.android.support:support-compat:26.1.0'
implementation 'com.android.support:appcompat-v7:26.1.0'
**implementation 'com.google.android.gms:play-services-analytics:16.0.5'**
}
..
There was no other changes in my code, but the fixed version worked on 4.x emulators too. Only the ** marked lines are changed.

The Problem is in Gradle File Please Increase the Version That's it
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.3'
}
}

[Solution] Use this special code
compileOptions {

}

Go to manifest -> inside application tag -> directly put your class name with dot or check the package of that file and add that manually.

Fatal Exception: java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV23

On my latest release a few of my users (less than 0.2%) are getting a crash because android.support.v7.app.AppCompatDelegateImplV23 can not be found. I can not reproduce the issue, I'm only getting reports over crashlytics. I have used apktool to extract the files out of my apk and I can see AppCompatDelegateImplV23.smali in there. Any idea what could be happening?
This is my compile line on gradle:
compile 'com.android.support:appcompat-v7:23+'
This is the exception:

EDIT: I've just gone over a lot of the reports, some are for AppCompatDelegateImplV23 and some are for AppCompatDelegateImplV14, some involved XPosed but most don't. The one thing that is common to all of them is that they are all for rooted phones.

First of all, we need to understand why java.lang.NoClassDefFoundError error occurs :
So the answer is that when there is a class file that your code depends on and it is present at compile time but not found at runtime. Look for differences in your build time and runtime classpaths.
So there are some options by that you can remove this error:
1) Make preDexLibraries to true:
dexOptions {
preDexLibraries = true
jumboMode = true
javaMaxHeapSize "2g"
//doesn't seem to be supported with multi dex
// incremental true
}
2) There may be the problem with the incremental build system. So try to try to remove your build folder from your project and Rebuild the project OR Right click on your project -> "Open module settings" -> Dependencies tab -> check if Export is checked for your library
3) You need to do more than just provide MultiDex support.
multiDexEnabled = true in your defaultConfig block
Include compile 'com.android.support:multidex:1.0.0' in your dependencies
Have your Application class extend MultiDexApplication instead of just Application. Alternatively, you can call MultiDex.install() in attachBaseContext() of your application
For more reference you can check the below link which has provided more advance understanding of multi dex.
https://developer.android.com/tools/building/multidex.html
4) Or at last you can add jar files of V7 into your project's libs folder and then add it your build System.
5) Also try removing the jar files as well as it still includes the com.android.support:support-v4:23+ as gradle has a repository where it downloads the jars delcared like compile 'compile 'com.android.support:appcompat-v7:23+'
Hope this can give you some clue about your error.

My guess is that the problem is due to the xposed framework. At the bottom of the stack trace, you can find that the zygote was started by the xposed framework.
at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:687)
at de.robv.android.xposed.XposedBridge.main(XposedBridge.java:117)
This means that the user is using a custom Android rom with the xposed framework installed. The framework is usually used to modify the behavior of the Android framework (and any app of course) code by injecting new code at run-time.
You can check how it works at: https://github.com/rovo89/XposedBridge/tree/art/app/src/main/java/de/robv/android/xposed
Since the code behavior can be altered in various degrees depending on what mods are installed via the xposed framework, I cannot pinpoint the exact cause of your exception. However, if all the stack traces you have got start with the XposedBrigde.main(), then I can say that your problem is due to the exposed framework or the mods installed via the framework.

NoClassDefFoundError with Android Studio on Android 4

I'm in the process of converting an existing app from Eclipse to Android Studio. However, when I run it on a device running 4.x (I've tested several versions on emulators), it immediately crashes with a NoClassDefFoundError.
I've tried commenting out references to the classes it can't find, but there's always another. As far as can tell, the offending class is always
Within my own code
An inner class (Update: With more investigation, this one isn't always true)
Everything works fine on a 5.0.1 emulator (I don't have a device to test on). My build.gradle file is fairly long, but looks like this:

Some examples of classes that cause trouble:
An anonymous class that implements an interface inside the facebook library (as a library project)
Parcelable.CREATOR implementations in my models
An inner class that extends android.os.Library
An inner class in my own code
A class that implements an interface in a library from maven
What's going wrong, and how do I fix it?

I was incompletely implementing MultiDex support, so some of my classes weren't in the proper dex file. To fix it, you have to do more than just set multiDexEnabled = true in your defaultConfig block. You also have to:
Include compile 'com.android.support:multidex:1.0.1' in your dependencies
Have your Application class extend MultiDexApplication instead of just Application. Alternatively, you can call MultiDex.install() in attachBaseContext() of your application.
See https://developer.android.com/tools/building/multidex.html for more details.

1) Add multiDexEnabled = true in your default Config
2) Add compile com.android.support:multidex:1.0.0 in your dependencies
3) Application class extend MultiDexApplication instead of just Application

1) add multiDexEnabled = true in your defaultConfig in build.gradle.
2) You also have to Include compile 'com.android.support:multidex:1.0.1'
3) add the following to your "application" tag in your manifest:
android:name="android.support.multidex.MultiDexApplication"
its working with me , hope that help

I solved the problem by removing multiDexEnabled = true in my case.

I also issue get resolved after doing following steps
1) add multiDexEnabled = true in your defaultConfig in build.gradle.
2) You also have to Include compile com.android.support:multidex:1.0.1
3) add the following to your "application" tag in your manifest:
android:name="android.support.multidex.MultiDexApplication"

I got the same issue, tried all solutions suggested on StackOverflow but they did not work in my case.
After that I found out that one of libraries compiled by Java 8. So, I need to enable Java 8 in my project too.
android {
//...
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
There are many reasons which leads to this error. Hope it helps.

In my case, it was Kotlin forEach was causing the exception.

Share external dependencies between modules in Android Studio

I'm trying to share 2 external dependencies between 2 modules in Android Studio.
The 2 dependencies are Twitter Core and Twitter4j (a Twitter library extension I'm experimenting with).
Here is the project structure:
Root project 'cineios-test'
+--- Project ':app'
\--- Project ':cineio-broadcast-android-sdk'
I set up the dependencies in my app build.gradle file:
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
buildscript {
repositories {
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
classpath 'io.fabric.tools:gradle:1.+'
}
}
repositories {
maven { url 'https://maven.fabric.io/public' }
}
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.lgorse.cineios_test"
minSdkVersion 18
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
packagingOptions{
exclude 'META-INF/LICENSE.txt'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile project(':cineio-broadcast-android-sdk')
//compile project(':cineio-broadcast-android')
//compile 'io.cine:cineio-broadcast-android-sdk:0.0.9'
compile ('org.twitter4j:twitter4j-stream:4.0.2'){
transitive = true;
}
compile('com.twitter.sdk.android:twitter:1.1.1#aar') {
transitive = true;
}
}
Here is the build.gradle file for the module, which is cineios-android-sdk:
apply plugin: 'android-library'
android {
compileSdkVersion 19
buildToolsVersion '19.1.0'
defaultConfig {
// applicationId 'io.cine.android'
minSdkVersion 18
targetSdkVersion 19
versionCode 11
versionName '0.0.11'
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
}
dependencies {
compile 'com.google.guava:guava:16.0'
compile 'com.loopj.android:android-async-http:1.4.5'
compile 'com.android.support:appcompat-v7:20.0.0'
compile 'com.android.support:support-v4:20.0.0'
}
Finally here is settings.gradle:
include ':app', ':cineio-broadcast-android-sdk'
project(':cineio-broadcast-android-sdk').projectDir = new File('cineio-broadcast-android/cineio-broadcast-android-sdk')
I know there are answers on SO but they refer adding local libraries as modules - but since these dependencies are remote I'm not sure how to adapt the hints to this situation.
I did try adding the dependencies to the other module (cineios-android) but a) it seems ridiculous to double them up like that and b)that would imply registering a new app in the Twitter API, which will probably lead to errors.

The correct approach really is to specify the dependencies in both the main app and the module.

There's really nothing ridiculous about it. Don't think of it as trying to "share" the dependency between the main app and the module. Look at it this way: your module depends on Twitter4j and Twitter Core. If you were to reuse that module in a different application, the module should be self-contained and should be able to specify its own dependencies without the parent project needing to set them up. Making all its dependencies explicit does this.
If the parent app also depends on Twitter4j and Twitter Core, and if you use the Maven Coordinate-style remote dependency specs as you have, the build system will ensure that only one copy actually gets linked into the app, so everything will be okay.
b)that would imply registering a new app in the Twitter API, which will probably lead to errors.
I'm not familiar with how that works, so I can't comment on it other than to say that if their API is well designed, hopefully just including the library shouldn't imply something like that. If you're having problems, clarify your question or ask a new one.

In your build.gradle add dependency like below:
dependencies {
compile 'org.openimaj:twitter:1.3.1'
}
