Answer 1

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.

Answer 2

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 !!!

Answer 4

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")
            }
        }
    }
}

Answer 5

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.
