Question

我创建了一个简单的活动。该活动允许用户从图库中选择图像或使用相机拍照。主要是它的工作正常，但是如果用户选择的图像有点大，我得到 JavaBinder（9581）：!!!失败的BINDER TRANSACTION !! logcat错误，活动关闭。

方法：

private void choosePhoto(){

    Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(i, RESULT_LOAD_IMAGE);
}

private void takePhoto(View view){

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, TAKE_PICTURE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){

    try {

        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {

            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            int rotationValue = ImageController.getCameraPhotoOrientation(getApplicationContext(), selectedImage, picturePath);

            Matrix m = new Matrix();
            m.postRotate(rotationValue);

            cursor.close();
            decodeImageFile(picturePath, m);
        }

        if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) {

            imageUri = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            if (imageUri != null) {

                    Cursor cursor = getContentResolver().query(imageUri, filePathColumn, null, null, null);
                    cursor.moveToFirst();
                    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                    String cameraPath = cursor.getString(columnIndex);
                    cursor.close();

                    Matrix m = new Matrix();
                    int rotationValue = ImageController.getCameraPhotoOrientation(getApplicationContext(), imageUri, cameraPath);
                    m.postRotate(rotationValue);

                    decodeImageFile(cameraPath, m);
            } else {

                    // Bundle extras = data.getExtras();
                    Matrix m = new Matrix();
                    int rotationValue = ImageController.getCameraPhotoOrientation(getApplicationContext(), imageUri, data.getExtras().get("data").toString());
                    m.postRotate(rotationValue);
                    // Need to work out what to do about the Matrix flip in the
                    // bug
                    // for Nexus5 Cameras.

                    nexus5CameraBugFix((Bitmap) data.getExtras().get("data"), m);
            }
        }
    } catch (Exception e) {

        Log.e("Exception", e.toString());
        retakePhotoDialog();
    }
}

logcat的：

11-26 12:31:27.441: E/JavaBinder(9581): !!! FAILED BINDER TRANSACTION !!!

我哪里错了？为什么我收到错误？

你应该为你得到的每个大位图压缩你的位图（来自gallery，来自netowrk）。以下是从图库中选择图片时始终使用的代码片段：

BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true;
    BitmapFactory.decodeStream(
            ctx.getContentResolver().openInputStream(selectedImage), null,
            o);

    // The new size we want to scale to
    final int REQUIRED_WIDTH = 300;

    // Find the correct scale value. It should be the power of 2.
    int width_tmp = o.outWidth, height_tmp = o.outHeight;
    int scale = 1;
    while (true) {
        if (width_tmp / 2 < REQUIRED_WIDTH
                || height_tmp / 2 < REQUIRED_WIDTH) {
            break;
        }
        width_tmp /= 2;
        height_tmp /= 2;
        scale *= 2;
    }

    // Decode with inSampleSize
    BitmapFactory.Options o2 = new BitmapFactory.Options();
    o2.inSampleSize = scale;
    return BitmapFactory.decodeStream(
            ctx.getContentResolver().openInputStream(selectedImage), null,
            o2);

在上面的代码中，selectedImage是指向所选图像的URI点。

你可以通过这种方式缩小图像大小来解决它：

public static Bitmap scaleDownBitmap(Bitmap photo, int newHeight, Context context) {

 final float densityMultiplier = context.getResources().getDisplayMetrics().density;        

 int height= (int) (newHeight*densityMultiplier);
 int width= (int) (height * photo.getWidth()/((double) photo.getHeight()));

 photo=Bitmap.createScaledBitmap(photo, width, height, true);

 return photo;
 }

选择newHeight并缩小图像。
