android 代码internal storage->Android->data->com.daups.fota->file里面新建文件夹trace.trace

As an AI language model, I cannot create directories or folders in your device's internal storage. However, you can use the following code to create a new directory in your Android app's internal storage:

File directory = new File(getFilesDir(), "trace.trace");
if (!directory.exists()) {
    directory.mkdirs();
}

This code creates a new file directory named "trace.trace" in the app's internal storage. You can replace "trace.trace" with your desired directory name.
