如何使用安卓设置应用的SettingsDumpService.dump()方法

public class MySettingsDumpService extends SettingsDumpService {
    @Override
    public void onDump(FileDescriptor fd, PrintWriter writer, String[] args) {
        // 在这里编写导出设置信息的逻辑
    }
}

<service android:name=".MySettingsDumpService"
         android:permission="android.permission.DUMP" />

public void dumpSettings() {
    try {
        // 创建一个FileDescriptor和PrintWriter对象
        FileDescriptor fd = new FileDescriptor();
        PrintWriter writer = new PrintWriter(new FileOutputStream(fd));

        // 调用SettingsDumpService的dump()方法
        MySettingsDumpService service = new MySettingsDumpService();
        service.onDump(fd, writer, null);

        // 关闭PrintWriter对象
        writer.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
}
