Question

我正在写一个标准的应用程序，拍摄照片，然后将其保存到手机，一旦我点击保存按钮，它保存图像，但崩溃与强制关闭，我在这里阅读至少10-15个线程同样的问题，但没有一个帮助。我正在测试三星Galaxy S

这是意图

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 

imageFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/picture.jpg";  

File imageFile = new File(imageFilePath); 
Uri imageFileUri = Uri.fromFile(imageFile);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,imageFileUri );
startActivityForResult(cameraIntent, 1337);

也是OnActivity

protected void onActivityResult (int requestCode, int resultCode, Intent data) {  
super.onActivityResult(requestCode, resultCode, data); 
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) 
    {  

     BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
     bmpFactoryOptions.inJustDecodeBounds = false;  
     Bitmap bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);
     image.setImageBitmap(bmp);
     }
    }

提前致谢

这是LogCat

Answer 1

如果没有看到你的LogCat，很难说是什么问题。但是，看起来你正在用相机拍照并以全分辨率加载它。 Galaxy S配备500万像素摄像头。

<（>（（2592 * 1944 * 32）/ 8）/ 1024）/ 1024 = 19.22 MB。您可能遇到OutOfMemoryError。

保存照片后，Android会一直崩溃
