当我们编写单词"应用程序"的代码颜色时，它会变为红色。谁能帮我解决这个问题？
这是我的build.gradle应用程序
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "com.example.nabeel.ask"
minSdkVersion 16
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner
"android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',
{
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
compile 'com.android.support:design:26.+'
compile 'com.facebook.android:facebook-android-sdk:4.6.0'
compile 'com.google.android.gms:play-services-auth:8.3.0'
compile 'com.google.android.gms:play-services:8.3.0'
}
