Question

我尝试在同一个活动中实施导出和导入（分别来往Google云端硬盘）到我的应用的可用性。

导出功能完美无缺。对于导入功能，我曾考虑使用播放服务中的Google Drive File Picker来获取要导入的txt文件的ID，然后读取该文件并将其导入我的数据库。

好吧，首先我连接到谷歌Api客户端，它确实可以用于导出。在onConnected方法中，我使用一个开关来导入或导出之间的分隔：

public void onConnected(Bundle connectionHint) {
    switch(driveCase){
        case 0:
            Log.i(TAG, "API client connected for export.");
            saveFileToDrive();
            break;
        case 1:
            Log.i(TAG, "API client connected for import.");
            pickFileFromDrive();
            readFileFromDrive();
            break;
    }
}

首先，我想显示GDrive文件选择器，所以：

private void pickFileFromDrive(){
    Log.i(TAG, "Open FilePicker Activity.");
    IntentSender intentPicker = Drive.DriveApi
            .newOpenFileActivityBuilder()
            .setMimeType(new String[] { "text/plain" })
            .build(mGoogleApiClient);



    try {
        startIntentSenderForResult(
                intentPicker, REQUEST_CODE_OPENER, null, 0, 0, 0);
    } catch (SendIntentException e) {
      Log.w(TAG, "Unable to send intent", e);
    }


}

这就是应用程序崩溃的点，文件选择器显示但我的应用程序停止工作......

这是onActivityResult：

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.i(TAG, "Taking result...");

            DriveId driveId = (DriveId) data.getParcelableExtra(
                    OpenFileActivityBuilder.EXTRA_RESPONSE_DRIVE_ID);
            pickedDriveId = driveId;

            Log.i(TAG, "Result Toke.");
        finish();

    }

关于可能是什么原因的任何想法？

提前致谢。
