Question

我要打开相机，单击并将完整图像上传到服务器。为此，我试图将图像保存到一个位置，然后从另一种方法上传。我在使fileprovider工作时收到此错误，并尝试了各种堆栈溢出解决方案，但似乎没有一种对我有用。

java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Android/data/com.learning.speeeddy.imagereader.app/files/Pictures/IMG_20180627_132113_1596259289.jpg

在MainActivity.java

private void dispatchTakePictureIntent() {
    Intent pictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if(pictureIntent.resolveActivity(getPackageManager()) != null){
        //Create a file to store the image
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File
            ex.printStackTrace();
        }
        if (photoFile != null) {
            Uri photoURI = FileProvider.getUriForFile(this,"com.learning.speeeddy.imagereader.fileprovider", photoFile);
            pictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
            startActivityForResult(pictureIntent, CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE);
        }
    }
}

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


    return image;
}

在AndroidManifest.xml

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

    <uses-feature android:name="android.hardware.camera"

</manifest>

在file_paths.xml（/ res / xml）

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="my_images" path="Android/data/com.learning.speeeddy.imagereader.app/files/Pictures" />
</paths>
