Android: 升级到新版本的 gradle 后出现“并购失败”错误

在接受更新项目到新版本的 gradle 之后，我得到了这个错误:

Error:Execution failed for task ':app:processDebugManifest'.
Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.0-alpha1) from [com.android.support:cardview-v7:26.0.0-alpha1] AndroidManifest.xml:24:9-38
is also present at [com.android.support:design:25.3.1] AndroidManifest.xml:27:9-31 value=(25.3.1).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:22:5-24:41 to override.

我怎样才能解决这个问题？ 这是我的应用程序的 build.gradle文件:

android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.sample.bookReader"
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
}
...
}


dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:multidex:+'
compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
compile 'com.android.support:cardview-v7:26.0.0-alpha1'
compile 'com.android.support:design:25+'
compile 'com.jakewharton:butterknife:8.2.1'
apt 'com.jakewharton:butterknife-compiler:8.2.1'
...
}

这是该项目的 build.gradle:

buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.1'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}


allprojects {
repositories {
jcenter()
maven { url "https://www.jitpack.io" }
}
}


task clean(type: Delete) {
delete rootProject.buildDir
}

我如何修复这个错误，同时维护通过更新等级版本所做的更改？

You are using multiple versions of the Android Support Libraries:

compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
compile 'com.android.support:cardview-v7:26.0.0-alpha1'
compile 'com.android.support:design:25+'

Two are 26.0.0-alpha1, and one is using 25+.

Pick one concrete version and use it for all three of these. Since your compileSdkVersion is not O, use 25.3.1 for all three of these libraries, resulting in:

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support:design:25.3.1'

  • Update your support library to last version

  • Open Manifest File , and add it into Manifest File

  • <uses-sdk tools:overrideLibrary="android.support.v17.leanback"/>

  • And add for recyclerview in >> build.gradle Module app :

  • compile 'com.android.support:recyclerview-v7:25.3.1'

  • And click : Sync Now

I changed all support library versions to 25.3.1 and worked like a charm:

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'

You also need to change compileSdkVersion and targetSdkVersion to 25:

compileSdkVersion 25
targetSdkVersion 25

Put this at the end of your app module build.gradle:

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '25.3.0'
}
}
}
}

The answer are accepted but one thing you could also do is to define the libraries from your project structure. What you can do is :

  1. Comment all the libraries in which problem is coming
  2. Goto your project structure
  3. Add libraries from there and it'll sync automatically and the problem goes off.
  4. If problem persists try looking from the error log that what library is it demanding after following all the above 3 steps.

What happens is the predefined libraries as off now now I'm taking the appcompat:26.0.0-alpha1 it uses the older version of the things when you add something new and tries to resolve it with the old stuffs. When you add it from your project structure, it'll add the same thing but with the new stuffs to resolve it. Your problem would be resolved.

you try read link this

It happen the same thing to me. See on Gradle -> Build Gradle -> and make sure that the compatibility matches in both compile "app compat" and "support design" lines, they should have the same version.

Then to be super sure, that it will launch with no problem, go to File -> Project Structure ->app and check on tab propertie the build Tools version, it should be the same as your support compile line, just in case i put the target SDK version as 25 as well on the tab Flavors. 

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-
core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
*compile 'com.android.support:appcompat-v7:25.3.1'*
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
*compile 'com.android.support:design:25.3.1'*
}

Thats what I did and worked. Good luck!

I'm not using different versions of libraries and got the same error, it's happened after remove buildToolsVersion in AS RC 1, but adding tools:node="replace" did the trick, just add this into your manifest.xml inside <application ..../> block:

<meta-data
tools:node="replace"
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

You can find out what library depends on a wrong version of the support library and exclude it like this:

compile ('com.stripe:stripe-android:5.1.1') {
exclude group: 'com.android.support'
}

stripe-android in my case.

The error for me was:

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.2) from [com.android.support:percent:26.0.2] AndroidManifest.xml:25:13-35
is also present at [com.android.support:support-v4:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:23:9-25:38 to override.

The solution for me was in my project Gradle file I needed to bump my com.google.gms:google-services version.

I was using version 3.1.1:

classpath 'com.google.gms:google-services:3.1.1

And the error resolved after I bumped it to version 3.2.1:

classpath 'com.google.gms:google-services:3.2.1

I had just upgraded all my libraries to the latest including v27.1.1 of all the support libraries and v15.0.0 of all the Firebase libraries when I saw the error.

I solve that with putting this at the end of my app module build.gradle:

    configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '26.0.0'
}
}
}
}

I have updated old android project for the Wear OS. I have got this error message while build the project:

Manifest merger failed : Attribute meta-data#android.support.VERSION@value value=(26.0.2) from [com.android.support:percent:26.0.2] AndroidManifest.xml:25:13-35
is also present at [com.android.support:support-v4:26.1.0] AndroidManifest.xml:28:13-35 value=(26.1.0).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:23:9-25:38 to override.

My build.gradle for Wear app contains these dependencies:

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.support:wearable:2.4.0'
implementation 'com.google.android.gms:play-services-wearable:16.0.1'
compileOnly 'com.google.android.wearable:wearable:2.4.0'}

SOLUTION:

Adding implementation 'com.android.support:support-v4:28.0.0' into the dependencies solved my problem.

Try deleting the meta data and rebuild project.
