Flutter 将 activity 添加到 Android ImageCropper 清单

Question

我正在尝试在我的应用程序中实施 ImageCropper。在 Android 上，我需要根据文档向清单中添加一些内容，但我无法使其正常工作...这是我的清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.memories">
<!-- Flutter needs it to communicate with the running application
     to allow setting breakpoints, to provide hot reload, etc.
-->
<application>
    <activity>         
    android:name="com.yalantis.ucrop.UCropActivity"             
    android:screenOrientation="portrait"             
    android:theme="@style/Theme.AppCompat.Light.NoActionBar"
    </activity>
</application>
<uses-permission android:name="android.permission.INTERNET"/>

但这会因以下错误而崩溃：

E/AndroidRuntime( 9936): at android.os.Looper.loop(Looper.java:223) E/AndroidRuntime( 9936): at android.app.ActivityThread.main(ActivityThread.java:7656) E/AndroidRuntime( 9936): at java.lang.reflect.Method.invoke(Native Method) E/AndroidRuntime( 9936): at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:592) E/AndroidRuntime( 9936): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:947) E/AndroidRuntime( 9936): Caused by: java.lang.IllegalStateException: Reply already submitted E/AndroidRuntime( 9936): at io.flutter.embedding.engine.dart.DartMessenger$Reply.reply(DartMessenger.java:155) E/AndroidRuntime( 9936): at io.flutter.plugin.common.MethodChannel$IncomingMethodCallHandler.success(MethodChannel.java:238) E/AndroidRuntime( 9936): at vn.hunghd.flutter.plugins.imagecropper.ImageCropperDelegate.onActivityResult(ImageCropperDelegate.java:106) E/AndroidRuntime( 9936): at io.flutter.embedding.engine.FlutterEngineConnectionRegistry$FlutterEngineActivityPluginBinding.onActivityResult(FlutterEngineConnectionRegistry.java:739) E/AndroidRuntime( 9936): at io.flutter.embedding.engine.FlutterEngineConnectionRegistry.onActivityResult(FlutterEngineConnectionRegistry.java:426) E/AndroidRuntime( 9936): at io.flutter.embedding.android.FlutterActivityAndFragmentDelegate.onActivityResult(FlutterActivityAndFragmentDelegate.java:677) E/AndroidRuntime( 9936): at io.flutter.embedding.android.FlutterActivity.onActivityResult(FlutterActivity.java:624) E/AndroidRuntime( 9936): at android.app.Activity.dispatchActivityResult(Activity.java:8310) E/AndroidRuntime( 9936): at android.app.ActivityThread.deliverResults(ActivityThread.java:5008) E/AndroidRuntime( 9936): ... 11 more I/Process ( 9936): Sending signal.

我在这里错过了什么？添加 activities 的正确方法是什么？

Answer 1

在 AndroidMainfest 中尝试此代码。可能是您在应用程序级别缺少启动器 Activity。

 <application
            android:name="io.flutter.app.FlutterApplication"
            android:label="example"
            android:icon="@mipmap/ic_launcher">
    <activity
        android:name=".MainActivity"
        android:launchMode="singleTop"
        android:theme="@style/LaunchTheme"
        android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
        android:hardwareAccelerated="true"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
            <meta-data
                android:name="flutterEmbedding"
                android:value="2" />
            <activity
                android:name="com.yalantis.ucrop.UCropActivity"
                android:screenOrientation="portrait"
                android:theme="@style/Theme.AppCompat.Light.NoActionBar"/>
  </application>

aaah...我改错了manifest...重要的是改main:

/android/app/src/main/AndroidManifest.xml

现在一切正常。
