在将Android Studio更新到3.0版本后,我无法预览我的应用程序的布局,我收到了以下错误:
'Failed to load AppCompat ActionBar with unknown error'.
我该怎么解决这个问题?但是如果我在我的设备上运行应用程序,它可以正常运行。
这是我的Gradle文件:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion '26.0.2'
defaultConfig {
applicationId 'com.halloo'
minSdkVersion 16
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
}
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-v7:24.2.1'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'
testCompile 'junit:junit:4.12'
}
dependencies {
compile 'com.squareup.okhttp3:okhttp:3.5.0'
}
dependencies {
compile 'com.android.support:support-v4:24.+'
}
dependencies {
compile 'com.android.support:cardview-v7:24.0.0'
compile 'com.android.support:recyclerview-v7:24.0.0'
}
dependencies {
compile 'com.android.support:support-v4:24.+'
compile 'junit:junit:4.12'
}
dependencies {
compile 'com.android.support:support-v4:24.+'
compile 'com.mikhaellopez:hfrecyclerview:1.0.0'
}
非常感谢您在此事上的时间和帮助。
compile 'com.android.support:support-v4:24.+'
