显式 Activity Class 未找到

Question

这是我出现错误的片段部分：

private void openaccess() {    
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {    
        if (ContextCompat.checkSelfPermission(getActivity(), android.Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
        } else {    
            CropImage.activity(mainImageURI)
                    .setGuidelines(CropImageView.Guidelines.ON)
                    .setAspectRatio(1,1)
                    .setAutoZoomEnabled(false)
                    .start((Activity) getContext());

            //  startActivityForResult(intent, CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE);
        }
    }
}

这是清单代码：

<?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="com.example.zub.epiphany_atlantic">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/epip_logo"
        android:label="EpiPhany"
        android:roundIcon="@drawable/epip_logo"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:replace="android:label">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".HomeActivity" />
        <activity android:name=".LoginActivity" />
        <activity android:name=".RegistrationActivity" />
        <activity android:name=".ProfileActivity"></activity>
    </application>
</manifest>

错误出现在 CropImage 的 .start((Activity) getContext()) 端。（我也试过 getActivity()）。

这是错误：

请帮我看看这里该做什么。似乎系统无法从清单文件中找到 .ProfileActivity activity。

您需要将 CropImageActivity 添加到您的 AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
  android:theme="@style/Base.Theme.AppCompat"/>
