Updated Android Studio - many errors now

Question

I was loading an old project into Android Studio. Android Studio asked to update which I allowed.

However - now I get error

build failed 10s 30ms Run build 9s 822ms Load build 10ms Configure build 413ms Calculate task graph 566ms Run tasks 8s 826ms null

In my

W:\android-studio-projects\sharedid\app\src\main\AndroidManifest.xml

file I have

<uses-sdk
  android:minSdkVersion="14"
  android:targetSdkVersion="25"
/>

...

In my

W:\android-studio-projects\sharedid\app\build.gradle 

file I have

compileSdkVersion 25

and

dependencies {
    api 'com.google.android.gms:play-services-maps:+'
    api 'com.google.android.gms:play-services-location:+'
    api 'com.android.support:appcompat-v7:+'
    api 'com.github.PhilJay:MPAndroidChart:v2.0.8'

also tried

    implementation 'com.google.android.gms:play-services-maps:+'

here is the whole file

My

Looks like this

buildscript {

        maven {
            url 'https://maven.google.com/'

        }
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

I am but lost on solving the Android Issues... Seems not to originate from my code but appcompat. Anyhow way to flush/fix this?

...

UPDATE 23rd April: I have made the following fixes

In W:\android-studio-projects\sharedid\build.gradle

dependencies {
    classpath 'com.android.tools.build:gradle:+'
}

In W:\android-studio-projects\sharedid\app\build.gradle

defaultConfig {
  applicationId "com.example.company.app"
  minSdkVersion 14
  compileSdkVersion 25
}

This resulted in a new set of errors - but I feel it is progress:

Answer 1

Although this already has an answer, this didn't work for me. For lot's of developers who might still facing this issue and are unable fix by any of the above mentioned work around. Please see, what worked for me. I noticed that in gradle.properties file there are 2 new lines,

android.useAndroidX=true
android.enableJetifier=true

Commenting these 2 in the gradle.properties made all my issues go away, and a successful build. I hope this helps to some of the developers finding the resolution.

Answer 2

You can solve the issue by updating the compileSdk version and build gradle of the app. First update the build tool version of the app to 3.1.1

dependencies {
    classpath 'com.android.tools.build:gradle:3.1.1'
}

Second change the compileSdkVersion version of the app.Two ways to update compileSdkVersion is:

1.Specify the buildToolVersion

defaultConfig {
    applicationId "com.robosoft.sampleproject"
    minSdkVersion 14
    compileSdkVersion 25
    buildToolsVersion '26.0.2'
}

2.If you dont specify build tool version increase the compilSdkVersion to 26 for gradle 3.1.1

defaultConfig {
    applicationId "com.robosoft.sampleproject"
    minSdkVersion 14
    compileSdkVersion 25
}

Answer 3

1. W:\android-studio-projects\sharedid\app\src\main\AndroidManifest.xml

---> You don't need add

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="25"
/>

2. W:\android-studio-projects\sharedid\app\build.gradle

   android {
   compileSdkVersion 27
   defaultConfig {
       applicationId "com.example.customer.app"
       minSdkVersion 15
       targetSdkVersion 27
       versionCode 1
       versionName "1.0"
       testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
   }
   buildTypes {
       release {
           minifyEnabled true
           proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
           signingConfig signingConfigs.release
       }
   }
   repositories {
       maven { url "https://jitpack.io" }
   }
   }
   
   dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   implementation 'com.google.android.gms:play-services-maps:15.0.0'
   implementation 'com.google.android.gms:play-services-location:15.0.0'
   implementation 'com.android.support:appcompat-v7:27.1.1'
   implementation 'com.github.PhilJay:MPAndroidChart:v2.0.8'
   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'
   }
   

3. W:\android-studio-projects\sharedid\build.gradle

   buildscript {
   
   repositories {
       google()
       maven {
           url 'https://maven.google.com/'
           name 'Google'
       }
       jcenter()
   }
   dependencies {
       classpath 'com.android.tools.build:gradle:3.1.1'
   
       // NOTE: Do not place your application dependencies here; they belong
       // in the individual module build.gradle files
   }
   }
   
   allprojects {
   repositories {
       google()
       maven {
           url 'https://maven.google.com/'
           name 'Google'
       }
       jcenter()
   }
   }
   
   task clean(type: Delete) {
   delete rootProject.buildDir
   }
   

You can try it.

Answer 4

When you update Android Studio, it always ask to update your gradle version.

If you allow to update the gradle version, Your whole build files need to update like Api's and target version Which is difficult to track.

What you can do is first re import as new project and don't allow upgrade the gradle version and try to compile then if it is compiled successfully then update your gradle version related to new Android Studio.

Answer 5

Remove the gradle from the project and let android studio make one

Answer 6

1. GoTO File>Project Structure(ctrl+ALT+Shift+S)
2. Click second button(Project) and change grade version to 4.4

Answer 7

In build.graddle(app)

try changing dependencies
