Error:Execution failed for task ':app:preDebugAndroidTestBuild' , when tried to run java program in android studio

Question

Getting the below error at the time of running java program in android studio.

Error:Execution failed for task ':app:preDebugAndroidTestBuild'.

Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

Any solution please. ?

For this you have to take a look at your dependencies and make sure that there are none of these conflicts. If you would like us to help you it will help to post your dependencies. — creativecreatorormaybenot, Apr 29 '18 at 17:34
I'm having the same problem. This is ridiculous. **It's a fresh new project.** Why would this happen?! Android Studio 3.0.1 — Alaa M., Mar 11 '19 at 05:53

Use implementation 'com.android.support:appcompat-v7:27.1.1' instead of implementation 'com.android.support:appcompat-v7:26.1.0' and change compileSdkVersion 26 to 27

I also updated `com.android.support` to 27: `implementation 'com.android.support:design:27.1.1'` and `targetSdkVersion` to 27. – E235 Feb 20 '19 at 07:37
What if I want to stay with SDK 26? Is it possible? – Alaa M. Mar 11 '19 at 05:55

For those who still facing the problem, above answer did not help me in android studio 2.2 Preview.

This fixed my issue.

add this to your gradle file.

configurations.all {
  resolutionStrategy {
    force 'com.android.support:support-annotations:23.1.1'
 }
}

Reference: https://github.com/JakeWharton/u2020/blob/05a57bf43b9b61f16d32cbe8717af77cd608b0fb/build.gradle#L136-L140

Android support library error after updating to 23.3.0

Resolved versions for app (22.0.0) and test app (21.0.3) differ

update - if the previous answer doesn't work :

you should update the compileSdkVersion and appcompat to the latest update till now compileSdkVersion is 27 , also appcompat is 27.1.1 and 28.0.0-alpha1 is a pre-release version

thus

change

compileSdkVersion 27

and

implementation 'com.android.support:appcompat-v7:26.1.0'

to latest update

implementation 'com.android.support:appcompat-v7:27.1.1'

you can check the latest updates from this link :

https://developer.android.com/topic/libraries/support-library/revisions

I also updated `com.android.support` to 27: `implementation 'com.android.support:design:27.1.1'` and `targetSdkVersion` to 27. — E235, Feb 20 '19 at 07:36

I answered before some minutes same question Reference. If you are not going to implement testing code, then remove junit from your app.

There are lot of other questions related to this.

Add these lines within your app dependencies braces,

android{
    configurations.all {
        resolutionStrategy.force 'com.android.support:support-annotations:27.1.1'
    }
}

Latest is 27.1.1 upto this date.

Well, I too faced the same problem here is how I fixed it

Goto app level Gradle file

There you will find what are all the config's you have set up. In my case here

android{
    **compileSdkVersion 26**
    defaultConfig {
        applicationId "com.xxxxxxxxxxx.yyyyyyyy.zzz"
        minSdkVersion 19
        **targetSdkVersion 26**
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    **implementation 'com.android.support:appcompat-v7:26.1.0'**
    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'
}

So here just change the compileSdkVersion & targetSdkVersion from 26 to 27 and

from dependencies change support appcomat

from   implementation 'com.android.support:appcompat-v7:26.1.0' 
to     implementation 'com.android.support:appcompat-v7:27.1.1'


android {
    **compileSdkVersion 27**
    defaultConfig {
        applicationId "com.xxxxxxxxxxx.yyyyyyyy.zzz"
        minSdkVersion 19
        **targetSdkVersion 27**
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    **implementation 'com.android.support:appcompat-v7:27.1.1'**
    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'
}

Got Fixed !!!

Error:

Error:Execution failed for task ':app:preDebugAndroidTestBuild'.

Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

This is due to there is no dependency added to your App build.gradle or might be its an old version. So, add a dependency for annotation support.

implementation 'com.android.support:support-annotations:27.1.1'

Here I have added annotation version 27.1.1 to solve your error if this is mismatched with different version then change it to the required version.

I found this very easy.

We will use update and use same version for all modules.

1. Go to project level `build.gradle`, use global variables

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlinVersion = '1.2.61'

    ext.global_minSdkVersion = 16
    ext.global_targetSdkVersion = 28
    ext.global_buildToolsVersion = '28.0.1'
    ext.global_supportLibVersion = '27.1.1'
}

2. Go to app level `build.gradle`, and use global variables

app level build.gradle

android {
    compileSdkVersion global_targetSdkVersion
    buildToolsVersion global_buildToolsVersion
    defaultConfig {
        minSdkVersion global_minSdkVersion
        targetSdkVersion global_targetSdkVersion
}
...

dependencies {
    implementation "com.android.support:appcompat-v7:$global_supportLibVersion"
    implementation "com.android.support:recyclerview-v7:$global_supportLibVersion"
    // and so on...
}

some library/module build.gradle

android {
    compileSdkVersion global_targetSdkVersion
    buildToolsVersion global_buildToolsVersion
    defaultConfig {
        minSdkVersion global_minSdkVersion
        targetSdkVersion global_targetSdkVersion
}
...

dependencies {
    implementation "com.android.support:appcompat-v7:$global_supportLibVersion"
    implementation "com.android.support:recyclerview-v7:$global_supportLibVersion"
    // and so on...
}

The solution is to make your versions same as in all modules. So that you don't have conflicts.

Tips for future

I felt when I have updated versions of everything- gradle, sdks, libraries etc. then I face less errors. Because developers are working hard to make it easy development on Android Studio.

Always have **latest but stable versions** Unstable versions are alpha, beta and rc, ignore them in developing.

I have updated all below in my projects, and feel flawless coding.

Update Android Studio (Track release)
Project level build.gradle - classpath 'com.android.tools.build:gradle:3.2.0' (Track android.build.gradle release & this)
Have updated buildToolVersion (Track buildToolVersion release)
Have latest compileSdkVersion and targetSdkVersion Track platform release
Have updated library versions, because after above updates, its necessary. (@See How to update)

Happy coding! :)

Add This Code to the bottom of build.gradle at app level. It will work...

configurations.all {
    resolutionStrategy.eachDependency{
        DependencyResolveDetails details ->
            def requested=details.requested
            if(requested.group=="com.android.support"){
            if(!requested.name.startsWith("multidex")){
                details.useVersion("26.0.1")
            }
        }
    }
}
