android - 在 Android 应用程序的 BlackBerry Playbook 上创建文件时出现问题？

转载作者：行者123 更新时间：2023-11-29 02:06:25

我正在使用 RIM 的 eclipse 插件在 Blackberry Playbook 上运行我的 android 应用程序。

我在“/accounts/1000/shared/documents”目录中创建的文件被“锁定”(当我浏览到它们并尝试使用 AIR 浏览器打开时，我收到错误消息“文件已锁定”)。我在“/sdcard”目录(由 Environment.getExternalStorage 返回的目录)中创建的文件工作正常。我可以使用以下代码以编程方式创建和读取这些文件。

关于如何在文档目录中创建未“锁定”的文件有什么建议吗？

public class TempActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        try
        {
            File docFile = new File("/accounts/1000/shared/documents/tmp.txt");
            File sdcardFile = new File(Environment.getExternalStorageDirectory().getPath() + "/tmp.txt");

            FileWriter writer = new FileWriter(docFile);

            try
            {
                writer.write("Hello doc file");
                Log.i("success writing doc file", "success writing doc file");
            }
            catch (Exception e)
            {
                Log.e("exception writing doc file", Log.getStackTraceString(e));
            }

            writer.close();
            writer = new FileWriter(sdcardFile);

            try
            {
                writer.write("Hello sdcard file");

                Log.i("success writing sdcard file", "success writing sdcard file");
            }
            catch (Exception e)
            {
                Log.e("exception writing sdcard file", Log.getStackTraceString(e));
            }

            writer.close();
            FileReader in = new FileReader(docFile);
            BufferedReader reader = new BufferedReader(in);

            try
            {
                Log.i("firstLine in doc file", reader.readLine());
            }
            catch (Exception e)
            {
                Log.e("exception reading doc file", Log.getStackTraceString(e));
            }

            in.close();
            reader.close();
            in = new FileReader(sdcardFile);
            reader = new BufferedReader(in);

            try
            {
                Log.i("firstLine in sdcard file", reader.readLine());
            }
            catch (Exception e)
            {
                Log.e("exception reading sdcard file", Log.getStackTraceString(e));
            }

            in.close();
            reader.close();
        }
        catch (Exception e)
        {
            Log.e("exception", Log.getStackTraceString(e));
        }

    }
}
