FileManager将进入ANR

Question

我启动FileManager的意图如下

    private void pickFile() {
       Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
       intent.setType("file/*").addCategory(Intent.CATEGORY_OPENABLE);
       startActivityForResult(intent, PICK_FILE_RESULT_CODE);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

       switch (requestCode) {
          case PICK_FILE_RESULT_CODE: {
              Log.d("Mass", "inside onActivityResult PICK_FILE_RESULT_CODE path:" + Util.getRealPathFromUri(mContext, data.getData()));
              launchFileUploadActivity(Util.getRealPathFromUri(mContext, data.getData()));
           }
           break;
    }
}
    private void launchFileUploadActivity(String path) {
         Intent i = new Intent(getActivity(), UploadActivity.class);
         i.putExtra("filePath", path);
         i.putExtra(Constants.KEY_APP_NO, mTrackData.getId() + "");
         i.putExtra("isImage", false);
         startActivity(i);
    }

如果我没有在FileManager中选择任何文件并单击“上一步”，它将无法理解错误所在。它甚至不会出现在onActivityResult上。请有人推荐我。我想要启动一个意图，就像gmail启动附件一样。

当我在gmail应用程序中点击附件时，我得到了这个ActivityManager的日志

{act=android.intent.action.GET_CONTENT cat=[android.intent.category.OPENABLE] typ=*/* flg=0x3080000 cmp=com.android.documentsui/.DocumentsActivity (has extras)} from uid 10068 on display 0
I/ActivityManager( 2420): Start proc 29052:com.android.documentsui/u0a40 for activity com.android.documentsui/.DocumentsActivity
I/ActivityManager( 2420): Start proc 29074:com.android.externalstorage/u0a10 for content provider com.android.externalstorage/.ExternalStorageProvider
I/ActivityManager( 2420): Displayed com.android.documentsui/.DocumentsActivity: +988ms (total +1s334ms)

有没有办法创建这样的意图来引用这个logcat

在调用launchFileUploadActivity之前，请检查data和data.getData()是否为null。

if (data != null && data.getData() != null)
    launchFileUploadActivity(Util.getRealPathFromUri(mContext, data.getData()));
