Question

我想打开相机并从相机拍摄照片以将其上传到服务器。但是，每次我尝试打开相机时，应用程序崩溃都会显示上述错误，我尝试了多种解决方案，但它们对我都不起作用。我的代码如下：

我的包裹名称是

lc.android.gauge

并且应用程序ID为

com.test.gauge

授予权限后，我称为此方法

private void dispatchTakePictureIntent() {

    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File
        }
        // Continue only if the File was successfully created
        try {
            if (photoFile != null) {
                Uri photoURI = FileProvider.getUriForFile(this,
                        "com.test.gauge.fileprovider",
                        file);
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
                startActivityForResult(takePictureIntent, 0);
            }
        } catch (Exception e) {
            Log.e("imageException", e.toString());
        }
    }
}

应用程序在上述方法中在此行崩溃

Uri photoURI = FileProvider.getUriForFile(this,"com.test.gauge.fileprovider",file);

createImageFile（）方法

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();
    return image;
}

内部清单标签

<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />

内部应用程序标记

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="lc.android.gauge.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />
    </provider>

file_paths xml

<paths>
<external-files-path
    name="my_images"
    path="Android/data/com.test.gauge/files/Pictures" />

FileProvider错误，尝试调用虚拟方法'android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData
