我之前已经看过这个问题了,但在你将这个问题标记为多余之前,我只想说我已经试图弄清楚这个问题三个小时了,我只是感到困惑。我的目标是拍摄照片,将其设置为imageview,然后将其上传到Firebase存储。为了获得完整尺寸的照片,我相信我必须将其保存到本地文件,因为FileProvider会引用文件以及全尺寸照片的位置。到目前为止这是正确的吗?我无法为我的生活获得FileProvider来实现这一目标。
经过多次尝试,这就是我所拥有的:
// It all starts here
public void onClick(View v) {
Log.d("DebugMySocks", "Change photo button clicked");
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
photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(getApplicationContext(),
getPackageName(),
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
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;
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mProfileImage.setImageBitmap(imageBitmap);
}
}
// in manifest file
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/filepaths" />
</provider>
// in /xml/filepaths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="com.example.kevin.moresocksplease/files/Pictures" />
</paths>
,错误信息为:
java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Android/data/com.example.kevin.moresocksplease/files/Pictures/JPEG_20171214_111337.jpg706457555.jpg
答案 0 :(得分:0)
替换:
<external-path name="my_images" path="com.example.kevin.moresocksplease/files/Pictures" />
使用:
<external-files-path name="my_images" />
