Android 相机意图在索尼手机中引发空指针异常

我想要的是

照相机意图

，它可以在除

索尼C2305

[4.2.2]以外的其他设备上完美运行。在4.2.2模拟器上进行测试，该模拟器运行良好

下面是代码片段。我使用呼叫

摄像机意图

 Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 getImagePath();
 intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
 startActivityForResult(intent, REQUEST_CAMERA);

---

将活动的结果获取为：

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
   if (requestCode == REQUEST_CAMERA) {
            if(resultCode == RESULT_OK)
            {
                BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
                btmapOptions.inSampleSize = 2;
                bm = BitmapFactory.decodeFile(currentFileUri.getPath(), btmapOptions);
                NewExpensesActivity.this.data.add(bm);
                imagesAdapter.notifyDataSetChanged();
                    compressedPath = ImageCompression.compressImage(currentFileUri.getPath());//ADDED 10018
                    galleryAddPic();
                    paths.add(compressedPath);//EDITED 10018

            }
        }
          }

但它在传递结果时抛出空指针异常 日志类别：

在这里，您没有在

tempFile

中提供任何图像名称，因此拍摄的图像可以使用该名称保存在SD卡中

现在，比如说，图像名称将是

123.jpg

…替换这个

File tempFile = new File(Environment.getExternalStorageDirectory().getPath()+"/ABC";);

与

File tempFile = new File(Environment.getExternalStorageDirectory().getPath()+"/ABC/123.jpg");

selectedImage是捕获图像的Uri，在索尼手机中工作正常。

where is

AddSxActivity.java:485

？检查onActivityResult中AddSxActivity.java类中的代码。你在那里得到了一些东西。另外，请发布您的全部活动代码。@SiddharthVyas:但同样的应用程序在其他手机上也可以正常工作。正是索尼导致了这些NPE。请检查编辑的SO。@Shayanpourvatan第485行：

bm=BitmapFactory.decodeFile（currentFileUri.getPath（），btmapOptions）

在其他手机上运行非常平稳，但没有抛出NPE。把它放在try-and-catch块中，现在让我们看看。我已经在传递那个些变量，正如你们所描述的那个样。请参阅。
