我正在尝试使用拍照Intent(MediaStore.ACTION_IMAGE_CAPTURE)并将其保存到外部缓存中。在开始活动之前，我要求获得CAMERA, READ_EXTERNAL_STORAGE,WRITE_EXTERNAL_STORAGE权限。创建的代码示例Intent如下：

private Intent createIntent() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    Uri resultUri = null;
    File path = context.getExternalCacheDir();
    if (path != null && !path.exists() && !path.mkdirs()){
          return null;
    }
    File file = new File(path.getPath(), "resultImage.jpeg");
    if (path != null) {
       resultUri = FileProvider.getUriForFile(
       context,
       context.getPackageName() + ".provider",
       file);
    }
    intent.putExtra(MediaStore.EXTRA_OUTPUT, resultUri);
    intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
    return intent;
}

在运行 Android 10 及更低版本的设备上，它可以正常工作，但在 Android 11 上，我收到此错误并收到RESULT_CANCELED或只是在相机应用程序中崩溃。

我的文件提供者：

        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"/>
        </provider>

和提供者路径：

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
    <cache-path name="cache" path="/"/>
    <external-cache-path name="external_cache" path="/"/>
</paths>

我也尝试使用getExternalFilesDir而不是缓存，但得到了同样的错误。
