Camera_intent가 중지되었습니다.

Question

저는 Android의 초보자이며 근본적으로 기본 카메라 응용 프로그램을 실행하고 사진을 찍어 장치에 저장하는 첫 번째 응용 프로그램을 최근 개발했습니다. 그러나 카메라 앱을 실행하려고하면 앱이 계속 충돌합니다. 이걸 정리하도록 도와주세요. 감사.

가 나는 또한 manifest.xml 파일에 권한을 추가 한

Answer 1

전나무 일 당신은 사진을 촬영 버튼을 클릭 할 때 :

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

          if (intent.resolveActivity(getPackageManager()) != null) { 
           File photoFile = null; 
           try { 
            photoFile = createImageFile(); 
           } catch (Exception ex) { 
            ex.printStackTrace(); 
           } 
           if (photoFile != null) { 

            Uri photoURI = FileProvider.getUriForFile(getApplicationContext(), 
              BuildConfig.APPLICATION_ID + ".provider", 
              photoFile); 
            intent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI); 
            startActivityForResult(intent, 1); 
           } 
          } 

방법 :으로 onActivity 결과에서 이제

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 = new File(Environment.getExternalStorageDirectory(), "FOLDER_NAME"); 
     File image = File.createTempFile(
       imageFileName, /* prefix */ 
       ".jpg",   /* suffix */ 
       storageDir  /* directory */ 
     ); 


     mCurrentPhotoPath = image.getPath(); 

     return image; 
    } 

:

try { 


        Uri takenPhotoUri = getPhotoFileUri(mCurrentPhotoPath); 
        new ProcessIMG().execute(takenPhotoUri.getPath()); 

       } catch (Exception e) { 
        e.printStackTrace(); 
       } 

방법 : 당신이이

public Uri getPhotoFileUri(String fileName) { 
     if (isExternalStorageAvailable()) { 

      File mediaStorageDir = new File(Environment.getExternalStorageDirectory(), "FOLDER_NAME"); 
      if (!mediaStorageDir.exists() && !mediaStorageDir.mkdirs()) { 
       Log.d("GymT", "failed to create directory"); 
      } 
      return FileProvider.getUriForFile(getApplicationContext(), 
        BuildConfig.APPLICATION_ID + ".provider", 
        new File(fileName)); 


     } 
     return null; 
    } 

xml이라는 이름의 폴더를 res와 cre 안에 만듭니다. menifest 넣어에서

<?xml version="1.0" encoding="utf-8"?> 
<paths > 
    <external-path name="/storage/emulated/0/" path="."/> 
</paths> 

이제 : 파일 이름 provider_paths.xml을 먹은 당신이의 Andorid 7.0에서 응용 프로그램을 사용하기 때문에

<provider 
      android:name="android.support.v4.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> 

private boolean isExternalStorageAvailable() { 
     String state = Environment.getExternalStorageState(); 
     return state.equals(Environment.MEDIA_MOUNTED); 
    }
