파일을 저장하려고 할 때 카메라가 손상됩니다.

Question

내가 갇혔습니다. 카메라에서 사진을 얻고 저장하는 방법은 다음과 같습니다.

> > @Override 
>  public File createImageFile() throws IOException { 
>   String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); 
>   String imageFileName = "JPEG_" + timeStamp + "_"; 
>   File storageDir = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES); 
>   File imageFile = File.createTempFile(imageFileName, ".jpg", storageDir); 
>   model.currentPhotoPath = imageFile.getAbsolutePath(); 
>   return imageFile; 
>  } 

@Override 
public Intent getCameraPictureIntent(PackageManager packageManager) { 
    Intent pictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    if (pictureIntent.resolveActivity(packageManager) != null) { 
     try { 
      model.userPicFile = createImageFile(); 
     } catch (IOException e) { 
      Log.i(TAG, "Can't create file!"); 
     } 
     if (model.userPicFile != null) { 
      model.userPicFileUri = FileProvider.getUriForFile(context, 
        "com.internship.droidz.talkin.fileprovider", 
        model.userPicFile); 
      pictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, model.userPicFileUri); 
     } 
    } 
    return pictureIntent; 
} 

나는 임시 파일을 만들고, 그 결과를 의도로 설정합니다. 그런 다음 결과에 대한 startActivity를 입력하십시오. 사진을 찍어 제출하면 앱이 다운됩니다. Logcat은 아무 말도하지 않습니다. Manifest.xml에

public class RegistrationModel implements RegistrationContract.RegistrationModel { 

    String currentPhotoPath; 
    Uri userPicFileUri; 
    File userPicFile; 
}

감사합니다. 모든! 대답을 사용하여이 문제를 해결했습니다. Android - file provider - permission denial

List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY); 
for (ResolveInfo resolveInfo : resInfoList) { 
    String packageName = resolveInfo.activityInfo.packageName; 
    context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION); 
}
