Question

我正在尝试为Android服装创建一个应用程序，但是一旦应用程序启动我就会收到此错误。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.demo.wear"
        minSdkVersion 21
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.support:wearable:1.2.0'
    compile 'com.google.android.gms:play-services-wearable:7.5.0'

    provided "org.projectlombok:lombok:1.16.4"

    compile 'com.jakewharton:butterknife:6.1.0'
}

我看到很多关于这个主题的问题，但我找不到解决方案。

以下是需要的清单和gradle文件。

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.demo.wear" >

    <uses-feature android:name="android.hardware.type.watch" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.DeviceDefault" >
        <activity
            android:name="com.demo.wear.ui.WishesActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Answer 1

一个正常的原因是活动的$scope.toHtml = function(string){ return $sce.trustAsHtml(string); }; - 属性中的包名称是错误的，但据我所知，在你的情况下它是正确的，我也看了一些我自己的gradle- / manifest-files，你的两个似乎都没问题。

因此我建议尝试清理整个项目，然后完全重建它（假设您使用的是Android Studio：Build-＆gt; Clean Project和Build-＆gt; Make Project）。这通常对我的情况有帮助。
