裁剪图像时出错

Question

我试图裁剪从Gallery和Camera中选择的图像。我不能裁剪大部分图像。它不叫onActivityResult()。以下是我的代码。每次在裁切图像后点击OK，我都会得到以下日志猫输出。

代码：

private void doCrop() { 
    Intent intent = new Intent("com.android.camera.action.CROP"); 
    intent.setType("image/*"); 

    List<ResolveInfo> list = getPackageManager().queryIntentActivities(
      intent, 0); 

    int size = list.size(); 
    if (size == 0) { 
     Toast.makeText(this, "Can not find image crop app", 
       Toast.LENGTH_SHORT).show(); 

     return; 
    } else { 
     intent.setData(mImageCaptureUri); 

     // intent.putExtra("outputX", 200); 
     // intent.putExtra("outputY", 200); 
     // intent.putExtra("aspectX", 1); 
     // intent.putExtra("aspectY", 1); 
     intent.putExtra("outputX", myImg.getWidth()); 
     intent.putExtra("outputY", myImg.getHeight()); 
     intent.putExtra("aspectX", 1); 
     intent.putExtra("aspectY", 1); 
     intent.putExtra("scale", true); 
     intent.putExtra("return-data", true); 
     intent.putExtra("outputFormat", 
       Bitmap.CompressFormat.PNG.toString()); 
     intent.putExtra("crop", "true"); 

     if (size == 1) { 
      Intent i = new Intent(intent); 
      ResolveInfo res = list.get(0); 

      i.setComponent(new ComponentName(res.activityInfo.packageName, 
        res.activityInfo.name)); 

      startActivityForResult(i, CROP_FROM); 
     } 
    } 

} 

的logcat：

请尝试整个源代码。

我正在使用相同的projet。这是该活动的代码：

代码：

private void doCrop() { 
    final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>(); 

    Intent intent = new Intent("com.android.camera.action.CROP"); 
    intent.setType("image/*"); 

    List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent, 0); 

    int size = list.size(); 

    if (size == 0) {    
     Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show(); 

     return; 
    } else { 
     intent.setData(mImageCaptureUri); 

     intent.putExtra("outputX", 200); 
     intent.putExtra("outputY", 200); 
     intent.putExtra("aspectX", 1); 
     intent.putExtra("aspectY", 1); 
     intent.putExtra("scale", true); 
     intent.putExtra("return-data", true); 

     if (size == 1) { 
      Intent i  = new Intent(intent); 
      ResolveInfo res = list.get(0); 

      i.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name)); 

      startActivityForResult(i, CROP_FROM_CAMERA); 
     } else { 
      for (ResolveInfo res : list) { 
       final CropOption co = new CropOption(); 

       co.title = getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo); 
       co.icon  = getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo); 
       co.appIntent= new Intent(intent); 

       co.appIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name)); 

       cropOptions.add(co); 
      } 

      CropOptionAdapter adapter = new CropOptionAdapter(getApplicationContext(), cropOptions); 

      AlertDialog.Builder builder = new AlertDialog.Builder(this); 
      builder.setTitle("Choose Crop App"); 
      builder.setAdapter(adapter, new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int item) { 
        startActivityForResult(cropOptions.get(item).appIntent, CROP_FROM_CAMERA); 
       } 
      }); 


      builder.setOnCancelListener(new DialogInterface.OnCancelListener() { 
       @Override 
       public void onCancel(DialogInterface dialog) { 

        if (mImageCaptureUri != null) { 
         getContentResolver().delete(mImageCaptureUri, null, null); 
         mImageCaptureUri = null; 
        } 
       } 
      }); 

      AlertDialog alert = builder.create(); 

      alert.show(); 
     } 
    } 
}
