我正尝试在基于官方CameraX演示应用程序https://github.com/android/camera/tree/master/CameraXBasic
的全新Android Studio项目中使用CameraX库。我已经在我的(模块)build.gradle中添加了以下依赖项:
implementation "androidx.camera:camera-core:1.0.0-alpha01"
implementation "androidx.camera:camera-camera2:1.0.0-alpha01"
和我的AndroidManifest.xml看起来像:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="simplediary.raouf.camerapoc">
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>
尝试运行项目时出现以下错误
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:1.1.0-beta01] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:9:3-23:17 to override.
现在将“ tools:replace =“ android:appComponentFactory”添加到清单中的application元素会导致此错误:
Manifest merger failed with multiple errors, see logs
因此,在AndroidManifest.xml的“ Merged Manifest”下,这些是我现在看到的错误:
Error: tools:replace specified at line:9 for attribute android:appComponentFactory, but no new value specified app main manifest (this file), line 8 Error: Validation failed, exiting app main manifest (this file)
如何解决此问题?完整的build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "simplediary.raouf.camerapoc"
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner
"android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation "androidx.camera:camera-core:1.0.0-alpha01"
implementation "androidx.camera:camera-camera2:1.0.0-alpha01"
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'
}
