如何创建一个新的可写文件？

Question

我有一个jobIntentService创建一个文件以便在其中添加一些文本，但我得到错误/data/user/0/com.example.projet/files/log.txt（Is a directory)。我不知道我做错了什么...下面是我的代码：

public void ecritureLog(Context context) {

        File path = context.getFilesDir();
        File file = new File(path, "log.txt");

        if (!file.exists()) {
            try {
                file.createNewFile();
            } catch (Exception e) {
                Log.d("Debug ecriture log", "exeption levée : " + e.getMessage());
            }
        }

        try {
            FileOutputStream stream = new FileOutputStream(file);
            stream.write("text-to-write".getBytes());
            stream.close();
        } catch (Exception e) {
            Log.d("Debug ecriture log", "exeption levée : " + e.getMessage());
        }
    }

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

谢谢你的帮助！

有了你们的评论，这就有了最后的代码：

public void ecritureLog(Context context) {

        File path = context.getExternalFilesDir(null);
        File file = new File(path, "/log.txt");

        if (file.exists() && file.isDirectory() ) {
            if (!file.delete()){
                Log.d("Debug ecriture log", "!file.delete()");
                return;
            }
        }

        try {
            FileOutputStream stream = new FileOutputStream(file);
            Log.d("Debug ecriture log", "chemin: " +file.getAbsolutePath());
            stream.write("text-to-write".getBytes());
            stream.close();
        } catch (Exception e) {
            Log.d("Debug ecriture log", "exeption levée : " + e.getMessage());
        }
    }

谢谢！
