Android X:tools:replace 在 line:for 属性中指定,但没有指定新值
我在这个网站上尝试了很多解决方案,但问题仍然没有解决.问题是由于 Android X 库造成的.当我添加 Android X 时,这个问题得到了解决,但它打开了新问题.如何解决这个问题?
I have tried many solutions on this website but still, the problem is not solved. The issue is due to Android X library. When I added Android X, this issue was resolved but it opened up new issue. How to fix this issue?
之前这个错误出现了:
Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:19:5-142:19 to override.
我添加了tools:replace="android:appComponentFactory"
后,出现了这个错误:
After I added tools:replace="android:appComponentFactory"
, this error is came:
java.lang.RuntimeException: Manifest merger failed with multiple errors, see logs
at com.android.builder.core.AndroidBuilder.mergeManifestsForApplication(AndroidBuilder.java:540)
at com.android.build.gradle.tasks.MergeManifests.doFullTaskAction(MergeManifests.java:173)
合并错误(在 Android 清单中):
Merging Error (in Android Manifest):

Error: tools:replace specified at line:2 for attribute android:appComponentFactory, but no new value specified app main manifest (this file), line 1

推荐答案
我认为您正在迁移到 AndroidX 库.
I think you are migrating to AndroidX libs.
将下面的行添加到 gradle.properties 文件
Add below lines to gradle.properties file
android.useAndroidX=true
android.enableJetifier=true
从清单中删除 tools:replace="android:appComponentFactory"
.
将 android.support.v7.app.AppCompatActivity
替换为 androidx.appcompat.app.AppCompatActivity
迁移到 AndroidX
