Android Studio报错Manifest merger failed : Attribute application@appComponentFactory value

本文主要是介绍Android Studio报错Manifest merger failed : Attribute application@appComponentFactory value，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Android Studio报错：

 What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86is also present at [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory).Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:10:5-24:19 to override.

意思就是说：

value=(androidx.core.app.CoreComponentFactory) from [androidx.core:core:1.0.0] 跟 

 value=(android.support.v4.app.CoreComponentFactory)

起冲突了，我在项目里引用的是：

 implementation 'androidx.appcompat:appcompat:1.0.0'implementation 'androidx.coordinatorlayout:coordinatorlayout:1.0.0'implementation 'com.google.android.material:material:1.0.0'

解决方案请看这篇文章：

AndroidStudio报错Manifest merger failed : Attribute application@appComponentFactory value=(android.sup

解决方案：

在清单文件 添加如下代码

  <application...android:theme="@style/AppTheme"android:appComponentFactory=""tools:replace="android:appComponentFactory">

我有两个项目都出现此问题了，第一个项目加入以上，就顺利解决了，但是第二个项目加入以后仍然报错：

Error:FAILURE: Build failed with an exception.* What went wrong:
Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.* Get more help at https://help.gradle.orgBUILD FAILED in 1s

仔细查看发现app的build.gradle文件出现问题了，这是有问题的：

implementation 'androidx.appcompat:appcompat:1.0.0'implementation 'androidx.coordinatorlayout:coordinatorlayout:1.0.0'implementation 'com.google.android.material:material:1.0.0'implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly'implementation 'com.android.support:appcompat-v7:28.0.0'implementation 'com.android.support.constraint:constraint-layout:1.1.3'

发现在编译的时候，不知道怎么就导入了最后两行，很明显跟第一行起冲突了，把最后两行删掉就行了，改后如下：

implementation 'androidx.appcompat:appcompat:1.0.0'implementation 'androidx.coordinatorlayout:coordinatorlayout:1.0.0'implementation 'com.google.android.material:material:1.0.0'implementation 'org.tensorflow:tensorflow-lite:0.0.0-nightly'
